This STUPID Fertilizer Experiment Killed EVERY ONE Of My Plants!

I took popular fertilizers with very different NPK ratios and tested them in a controlled experiment to attempt to answer one of the biggest gardening questions: does NPK ratio matter, and does changing NPK ratios influence plant growth and behavior? The results of this experiment shocked me, and I learned more about fertilizers as a result.
This fertilizer experiment took place over 70 days. I will take you through the entire experiment from start to finish, as well as explain what the NPK ratio is, how NPK ratios can affect plant growth and much more.

what about that "miracle gro soil"? I used it to plant grass seed and the grass turned yellow! Must be the same problem - no trace nutrients - good theory! I've been adding mulched grass and that seems to be saving the grass.

[@donnabrooks1173]

Love the pumpkin recipe. Dale is very much loved and spoiled as they should all be. You and Britney are awesome parents. I think your theory sounds very logical, like plants, we need trace minerals along with the vitamins. We could possibly die if we totally lacked some of them as well. What do you about a vegan fertilizer experiment?

[@danoenco9487]

Reminds me of the urine VS miracle grow experiment. I'm still hoping you revisit that one with a 1/3 compost mix rather than 100% coir.

Unlike Laura/Garden Answers who might mention a failed planting only if enough people comment on it, but even then it's very "oh I don't know what happened" followed by a quick shrug & off to the next topic. She's not a gardener..... she's a plant hoarder

[@luclucas135]

This is a failed conclusion to a failed experiment....

[@TheMillennialGardener]

So do I. I honestly learned more making this video than I have any other videos this year. I am happy to share the experience with the community.

[@Ash-fd8ww]

This is what is so important. Without these honest, fair, and truthful results, any garden video could lead someone to copying it, and having disasterous results without the huge funding to fix it (that some other channels have). Thank you so much. This is as shocking as the Miraclegro vs. Kellogg's results by EpicGardening, and the Miralegro vs urine conclusion from your own channel.

[@samsteel4456]

You were basically trying to run a hydroponic dutch bucket system but failed when you added peat moss which is organic and holds on to way too much water . Additionally, it has the potential to significantly change the ph of the medium to very acidic, locking out many nutrients and preventing availability to the plants. You should repeat the experiment with only perlite. It is not organic and won't add anything to the system, unlike peat moss when it breaks down. Set up the same experiment but this time, wash off the dirt from the roots as best as possible and then plant in perlite. Set up a watering schedule for 4-6 times per day for a minute or so and drain to waste. That way you will see the affects from only the fertilizer and not the decomposing peat moss. No offence, but i think your theory of why that experiment failed is way out in left field and has nothing to do with miracle grow not providing various micronutrients. I think it failed due to nutrient lockout and lack of oxygen to the roots.

[@jujube2407]

This 100%

[@davidjslack]

Correct. It’s a hydroponic experiment. Hoocho grows in straight coir without draining. Tons of food. Rerun the Miracle Grow experiment after mastering fundamentals of hydroponics.

[@mcgritty8842]

I was thinking similar. Ph, ec and ppm probably need to be considered; similarly to inert cannabis grows (I’m a noob)

[@SubvertTheState]

Bravo. Yeah I think soil that's oversaturated with water has straight up murdered my plants before. It creates an anaerobic environment around the roots so the only things going on biologically are decay.

[@habaristra6248]

Whenever a transplant's growth is stalled , or I miss the schedule to take starts out of the cells and transplant into bigger pots or into the ground...I use a very diluted solution of hydro chemicals (tomato blend). This technique has worked flawlessly. If I were to use Miracle Grow instead? Death and Damnation.

[@GetMeThere1]

The lesson I draw from this is that you can't go wrong with quality topsoil and compost as a healthful basis for plant growth.

[@TheMillennialGardener]

What I think I learned is that $7 boxes of MiracleGro aren't enough to satisfy the needs of plants. They work great to boost plants when given supplemental organics and healthy soil, but they're not enough on their own. From now on, I'll look at them more like a supplement than actual food.

[@lynnwilhelm7928]

​​@@TheMillennialGardener you can't draw that conclusion from this experiment. I'm pretty sure those products aren't meant to be used in a nearly inert medium. Remember too that we don't "feed" plants. They make their own food. We provide the nutrients they need to make that food. And technically plants make that food from carbon hydrogen and oxygen (pretty much from the air).

[@JM-ym8mm]

@@TheMillennialGardener That's the wrong conclusion to reach

[@JohnJohn-wr1jo]

I think that what you discovered is what I've believed and practiced for years. Fertilizers are simply an ammendment that should only be used if your soil is lacking necessary nutrients and you want instant results. When building soil those ammendments can be sourced naturally and are superior to the commercial NPK fertilizers. We always tended our compost heaps and supplemented beds with organic mushroom compost from local growers. Long term this is the only way to go in my opinion. I know too many gardeners who go the synthetic and even organic fertilizer route and the long term results are less than desirable.

[@jeil5676]

Every experiment is supposed to have a "control". Your results dont mean much without one. In this case you should have had 2 more pots with the same soil but you dont add any food, water only. You could have had an additional 2 more pots on top of that in which you fed with organic food, be it granular mixed into the medium or water sol. or w/e. Always use a control.

[@sisterclare1]

There may be another factor at play here and it doesn't have anything directly to do with the micros, and you kinda answered it yourself. First you added dissolved fertilizer every 2 weeks into an inert medium. The plants had a feast or famine feeding. The inert media has no nutritional carry over. Any organic such as compost, fish fertilizer etc breaks down slowly, even when pre-digested and continues to feed for many days/weeks after application. That is why when used as a supplement to the liquid fertilizer solution the plants do better. If you were to ration out the same amount of liquid fertilizer into your daily watering schedule so in 2 weeks the same dose was applied, I say your plants would have done much better. Hydroponics works the same way with diluted doses applied daily over time and the plants thrive...For your consideration. Happy gardening.

[@marcfruchtman9473]

That is another possibility as well.

[@TheMillennialGardener]

I think the plants would have had a better shot had I fed them less but a lot more often, but seeing the results of the experiment, I'm very much convinced it was a micro-nutrient deficiency. If you look at the labels at 2:50, they aren't very impressive, especially when you compare them to my big back of Jack's 20-20-20, which contains more things. I'm going to have to re-structure the experiment to account for these missing micros/secondary macro's. I think MiracleGro is less expensive than Jack's and other water soluble fertilizers for a reason. They don't have the trace nutrient content.

[@tendrocksteve]

​@@TheMillennialGardener You should be able to identify exactly which micronutrient deficiency they had as the symptoms are quite varied. You can't because that's not what caused your plants to die. As an elder millennial (born in 82) I probably had more experience as an 18 year old growing weed in my basement with miracle grow potting mix and miracle grow 15-30-15 alone than you do now. I used the small scoop per gallon to fertilize (not feed because plants eat light, I don't say I'm feeding myself when I take a vitamin) If you use a huge dose of fertilizer like you did you better be damn sure the soil never dries out at all because that will concentrate the salts and burn your plants. But go ahead and disregard my comment like you're doing with everyone else because you did your research and noticed there are more ingredients in one brand than another. A lot of those extra micronutrients are added in hydro formulations because it's common to use RO water, tap water has plenty of micros. Peat moss and coco coir are technically compost and have trace minerals in them as well.

[@theromulus8772]

I grow in inert material (coco+perlite) and if I did not water with fertilizer every time I would have some serious deficiencies. The work around to that would be slow release granules but even with that the results aren't so great.

[@justin1730]

Peat has a good cation exchange capacity. It helps to use dolomite lime as a pH buffer. If you are not adding compost for micronutrients, it is important to fertilize with hydroponic solution that contains the full range of usable nutrients.

[@ursamajor1936]

There is no such thing as an inert median that plants can grow in like soil , perlite won't work by itself as a median and neither will rock wall or clay pellets, funnily enough clay itself is the only completely inert median in nature but it has to be made into pellets for it to be well draining and than it's not able to hold enough water

[@kenhetro6742]

I've used Miracle Grow on my plants for 60 years along with other organic and non organic fertilizers. I worked for a huge greenhouse back in the early 1970's, which supplied all kinds of flowers to many of the florists in the whole valley. They used a water soluble fertilizer every time they watered their plants, but they only used half of the amount of fertilizer. I use miracle grow on my garden and grow tomatoes 10 feet high with a basket of tomatoes per plant. I know from years of gardening that potted plants will never do as good as plants grown in the garden.

As someone who does nutrient IV therapies in humans, I feel it’s similar-one cannot take a big concentration of any nutrient. Minerals often share channels and too much of one will block absorption of others. You can cause cardiac arrest by taking too much potassium, or magnesium, as it crowds out calcium which shares the same uptake channel (e.g. tunnel)

[@biancad2775]

As far as I remember, peat moss is used to lower the ph of the soil. I guess tomatoes don't like such an acidic environment.

[@thedivide3688]

Tomatoes like acidic soil. And the peat moss you get these days doesn’t really have that low of pH. And the science behind peat moss and studies have shown that the lowering of pH caused by peat moss is totally diminished in a week’s time. Coco peat also isn’t peat moss and the pH range pf coco peat is inline with what tomatoes want.

[@TheMillennialGardener]

Tomatoes love an acidic environment. I don't think the issue is with peat moss. All my potted plants, including all the giant tomatoes under my shade cover, are grown in the exact same mix. The only difference is that I add compost and mulch on top, and I fortify the soil with bone meal and organic 5-5-5. I think that MiracleGro products are just not designed to be the *only* thing you give your plants. They're made to enhance growth, not be the only thing given.

[@thedivide3688]

@@1165slugman If you do the research most of American potting soils based on peat moss have a relatively neutral pH. It has nothing to do with soil pH. Coco peat has been an issue for years in the nursery trade. Countries like the UK that have banned sphagnum peat moss are struggling with using Coco peat. It’s an okay media if you mix it in soil blends. By itself it’s horrible solo media.

[@diananazaroff5266]

I think the experiment was a total success! You were able to show that the base soil is very important. Fertilizers are great for additional nutrition, but you have to start off with something good. I'd love to see you use the initial soilless mix and add your homemade compost. Understood that everyone's compost will be different, but I'd like to see what that does for a plant. You could make it even more interesting by adding your Jacks 20-20-20 to one of the plants and not to the other. I experiment all the time with my plants. I'm currently growing peppers in a 6" wide x 8" deep x 24" long railing planter - and I've got 3 plants in each pot. I have to water them a little more because of the heat (I'm in GA), but they're doing very well.

I love your experiments. Thank you for taking the time to make those kind of videos as they are very important. Last Fall, I emptied my matured compost and dug it into my veggies beds. In March, I started my heirloom tomatoes (from my saved seeds) in a sterile potting soil intended for indoor plants, rather than in a seed starting soil. As soon as the first true leaves appeared, I started feeding them with half of the recommended doze of Miracle Grow water soluble 20-20-20 fertilizer. Later, I transferred the seedlings into 750 g yogurt containers (with drainage holes). I added some Miracle potting soil mixed with a bit of bone meal. By now, the seedlings did not fit under my grow lights, so I placed them inside my flimsy cold frame. When overnight frost was forecasted, I brought them indoors for the night and took them back out in the morning. This back and forth was going on for about two weeks. After the last frost date, I was ready to plant them into the ground. I put a handful of pelleted chicken manure, that contained calcium into each planting hole, lightly dusted the entire bed with dolomite calcium and watered each plant with transplanting fluid to prevent transplanting shock. Now, I continue to feed them every 10 - 14 days with Miracle Grow water soluble 20-20-20. My indeterminate heirloom tomatoes are growing strong 1' thick main stem and are 10 feet tall. I am harvesting fruit, that is noticeably bigger than it in the previous years. I believe that I have finally discovered the winning combination of organic + synthetic, from seed germination to harvest. By the way, I treated my peppers exactly the same as the tomatoes. Out of 8 pepper plants of the same variety, only one had end of blossom rot. At my ripe age, after gardening for the past 45 years, I finally started writing notes in my 1st gardening journal.

[@WompWompWoooomp]

I think you're on the right track with nutritional deficiencies, but I think it's secondary nutrients that are missing not trace nutrients. None of the formulas have any calcium, only the tomato formula has magnesium, and the all purpose and tomato have low levels of sulfur while the bloom booster has virtually no sulfur. The Bloom Booster not having any meaningful Sulfur certainly makes me wonder if that was the reason those plants didn't make it, as Sulfur is very important for plants. It'd be interesting to run the same experiment again but supplement the missing secondary nutrients to see how that changes things.

This is why I grow in-ground. So much less to worry about as far as fertilization and watering. I both fertilize and water my plants, but you can get by with doing neither and odds are your plants will produce something. I had a few volunteer tomato plants pop up in my pollinator garden last year that I didn't notice until later in the summer and they produced tomatoes with ZERO intervention from a human. No watering, no fertilizing and no staking and pruning.

out of all the fertlizers I've used, nothing beats good old blood, fish and bone for me. Every so often I just mix some into the top of the soil and water it in, can always see a big difference after I do it too. I don't really care to use specific fetlizer's, I've personally not seen any differerence when I use tomato fertilizer vs the bFB combo during the flowering/fruiting phase.

[@TheMillennialGardener]

I agree with most of the stuff we grow (except for crazy crops like corn and watermelons), but I believe it's very important that gardeners run stress tests like this to find out what doesn't work. These plants were sacrificial experiments, and I'm very glad I did this, because it taught me what the lower limits of plants and fertilizers were. I recommend every gardener try to design experiments and test the limits of the system until failure.

[@kooltube100]

@@TheMillennialGardener ey every garden is different. So maybe that applies to how specific fertlizers react to the plants. My soil is fairly clay but not in a crazy way, it'll probably hold onto liquid nutrients more due to that.

I think you are the first Gardner I have seen do this type experiment! Thank you!

[@joshuahoyer1279]

From my understanding, because both coco coir and perlite are completely inert in nature, they don't even have much nutrient retaining capacity. So after fertilizing, anything that runs out the bottom isn't even feeding the plant. And any time the plant is watered between feedings, any nutrients that do manage to stick around are washed out the bottom. It sounds like the poor plants just starved to death. Peat moss (controversy aside) retains a lot more nutrients, so maybe even changing that variable could make a big impact on the experiment?

[@KLFaber]

Yes, please re-do the experiment. Suggestion: Add a control plant so we can see how well the independent variable performs vs. doing nothing. My pepper plants have stopped putting on new blossoms and have thus far seemed immune to water soluble fertiziler. I am gong to try shade cloth next (zone 8a Atlanta, every day is 93 degrees).

[@mcgritty8842]

Keep the experiments coming. That’s how we keep open minds and thinking how to move forward with progress. I’m usinf a combo of granular and liquid feed for just extra quick nutrients My opinion (I’m new gardener) is that with inert soil, there can be a few extra factors to consider with liquid feeding like ph, ec and ppm. Some cannabis growers tend to use inert soil with only liquid feedings and they are anal about these things. If I remember correctly, feedings outsize the ph range can lead to nutrient lockout, similarly if the ppm is too high, the plant won’t absorb all the nutrients. I’m learning through others, my failure and if anything I say helps anybody in any possible way, then sweet. If not, I’m just glad to be heard cause I know someone read some of this 😂❤

Good morning! first off i appreciate all your content. it has helped me to be a better gardener. this year i have been reworking my garden adding raised beds and sun screen. when i built my raised beds I filled them with 6 inches of rough cut mulch on the bottom 6 inches then added 8 inches of organic compost to them. please note i live in the Missouri Ozarks so i went to Springfield recycle center and got the mulch for $8 a yard and Hansen's tree service for the compost at $40 per yard. i planted my 8 varieties of tomatoes, peppers, swiss chard, green beans, sunflowers, okra and summer squash. After about 3 weeks my plants (started from seed ) was very pale green and not growing at all the looked like they were dyeing. i have been gardening for the last 8 years directly in the soil and have had no problem i always add 1/8 cup of 10-10-10 and a table spoon of lime to the holes before i plant my plants and do not fertilize again and we get a large amount of tomatoes. we usually have 15 to 20 tomato plants and this year we have 40 tomato plants. I followed this standard this year also. Anyway looking at the plants i decided i needed to fertilize so i top dressed with a heave doe of 10-10-10 and then started a weekly watering of Miracle Grow tomato fertilizer like you used. all of my plants took off an became dark green ad started to grow. since ten i have kept up the weekly dose of Miracle grow and have again top dressed with 10-10-10. also i have added composted manure. to make a long stoy short after much time on the internet i determined that new compost does not have any nutrients in it as it until it starts breaking down. so i should be in better shape next year. i appreciate your content keep helping us novice gardeners. by the way my wife has demanded all the 36 by 65 ft garden be in raised beds next year :)

The medium became too acidic. In hydroponics, you need to PH balance the fertilizer liquid mix. That would kill the plants alone, it wouldn’t kill the plants if it was PH balanced.

[@TheMillennialGardener]

I don't think this is the case. All my tomatoes, cucumbers, squash, figs, etc. in my shade tunnel are grown in the exact same medium. The difference: I add organic 5-5-5, bone meal, I amend the tops with a few inches of compost, and I mulch them. I don't think this has anything to do with pH, because I had similar results when I used coco coir. I think all this shows is that inexpensive fertilizers like MiracleGro aren't nutritionally complete and it cannot be the only thing you give plants in a synthetic medium.

[@florencejessup2432]

Garden experiments are so much fun. Thanks for sharing this one with us. Often what we learn has less to do about growing our garden and more to do with scientific theory and testing our theory. In this case The Millennial Gardener states he wants to learn "What is the best fertilizer and does NPK really matter". But, the study he undertook actually tested "what happens to tomatoes and peppers, placed in an inert growing medium, when given infrequent feedings of various liquid fertilizers. In other words, it's not a valid test of his initial question. It also means there are at least five variables to consider in evaluating the outcome, the plants themselves, the growing medium, the fertilizer being applied, the method of application, and the frequency of application. Given that how do we evaluate the results? Here's one of many possibilities: Those of us that are experienced growers know that an inert growing medium does not provide enough nutrients to a plant to sustain life. We also know that the inert mix he selected drains pretty quickly. Since the method of application was a liquid drench, this means the nutrients drained from the medium fairly quickly. Since the frequency of application was every 14 days, this means that the plants were going for 12 or 13 days with no nutrients at all. So, one possible conclusion is that two weeks of starvation followed by a jolt of nutrients is not sufficient for plants to grow. Given the number of variables, there are other possible explanations for the outcome too, many of which have already suggested. Again, a fun lesson on how to design a scientific experiment . And, now we know why almost every study ends with a conclusion that "further study is required!"

[@rockinbobokkin7831]

I think the pH of peat moss could be a factor. If a plant isn't in ideal pH per that organism, it won't uptake nutrients. I use compost and manure with liquid fertilizer boosts, however I grew hydroponic plants or inert mediums and liquid fertilizers for many years. So, I believe a crucial missing element to your experiment is pH. Test your rain reservoir, then check your mixtures, and then check the pH of your soil medium with your water, and again with your fertilizer-water mix. Lots of people grow tomatoes in hydroponic systems, pH is crucial. If the peat is too acidic, and your rainwater is around only 5.5 , tomatoes will struggle. You need that pH boosted up to 6-7

Regarding coco coir, I had heard that salt is used in processing it, but if so, and then you add the micronized salt in the urea fertilizer, it's like double salt. I prefer to add both green and brown broken-down matter to make my soil, and supplement with more of this in this mixed with water to ferment for 2 days, then dilute with water and feed. I have also had good luck with pulverized bananas and egg shells in water to provide a boost of growth. It's like a sugar fix but has potassium and calcium, and potassium helps with heat stress. And yes, I use shade cloth too in zone 6B.

Keep up the great work! Now if we can get more rain around here....

[@jujube2407]

Peat moss is organically inert... but not chemically inert... you need black peat to be as close to chemically inert as possible... Highly decomposed peat will tend to remain more chemically stable as the organic decomposition process has already been carried out. For this reason you want to buy what is commonly known as “black peat” (H7-H10) where microbial activity has already dialed down and the peat moss more closely approaches what we would call an “inert media”. This however does not mean that Peat moss is chemically inert at this point as it does contain as a significant amount of substances that can affect your nutrient solution. One main characteristic of peat is that it’s acidic. This means that the pH of untreated peat will usually be between 3 and 4.5, too low for use in hydroponic applications. Peat is generally amended with calcium carbonate (lime) to make its pH go up and remain there but this process can be ineffective if the peat can still decompose very significantly (if you buy peat with decomposition < H7). This also contributes high amounts of Ca into the media which might lead to nutritional problems if Ca is also applied normally in solution. To alleviate these issues peat is also sometimes treated with lime/dolomite mixtures so that the counter-ions are both Mg and Ca. Alternatively - but more expensively - this problem can be solved by using phosphate buffer solutions that are run through the peat for a significant period of time. A potassium monobasic/dibasic phosphate buffer at a pH of 6.5 with a 100 mM concentration can buffer the peat moss. For this the buffer needs to be applied until the run-off pH out of the peat comes out unchanged. Then tap water should be applied to remove the K/P from the media. Note that this will only work for black peat that’s already gone through most of the decomposition process as lighter peats will simply decompose further and acidify the media again.

[@glennluteraan4434]

Samsteel is on the right track. Coco coir/perlite would have done better as it would not lower the PH like Peat moss. That being said, the main issue was PH and not a lack of micronutrients. Even the solution was too acidic and needed to likely be PH'd up to 6.0+/- and you would have had success. Soil would have buffered the PH and would not have required adjustment like the inert material does. The experiment would still have worked in Peat moss had you raised the PH of the fertilizer to compensate for the acidity of the moss. Basically, you locked out the ability for the plant to absorb all the different NPK.

[@deborahdunn7844]

Geez. They sound awesome! You can run those indeterminate tomatoes sideways once they reach 5 or 6 feet. Would love to have those green tomatoes to cook. Ummmmm.

This awesome what kind of fertilizers

[@hamsicle]

Alaska 5-1-1 to start and Neptune's 2-3-1 as they bloom. Boom, done. When I start seedlings, I water the tray with a dilute 5-1-1 fish emulsion and then just water. I'll fertilize them once when they go in the ground and then one more time with neptunes when they're done with veg.

Watermelon? Come on now! 😂

[@donnabrooks1173]

​@@deborahdunn7844 Yes!!! Coated with corn meal and fried. Yummy!! Red ones would be great for sandwiches and cooking with recipes. Less chopping.

[@cherylmackowiak3728]

So much wrong with your ‘experiment’. You did not test the null hypothesis and requires one , and for your case, two types of controls, as well as replication. Your plants look to have suffered from salt burn (way too much fertilizer). Note the burned leaves and apical buds. You did not test nutrient balance as you claim. Additionally, your potting mix was likely acidic, which alone would probably be ok but it added insult to injury to your poor plants. You have good ideas but need some professional guidance on how to appropriately test you hypotheses. A good Master Gardener’s course or conversations with your county extension team (free advice from professionals with years of trained experience) will help get you to where you are trying to go with this type of testing. Be careful with your claims and recommendations. In this case it’s horticultural malpractice.

I have to say, I've followed and listened to y, bought the products you suggested and have had success. I've learned lots from you. Thank you.

Might be the best video you've made yet. One thing I know for sure is that gardening comes with an element of failure. That's how we learn. I appreciate this video.

1st… 😊

Thanks for watching!

I use a mix of slow release miracle grow all purpose, and a lesser known brand of 10-10-10 slow release, as well as putting plants into some solid soil to start with. I usually just grab the 2 cu ft StaGreen bags and it has a good enough mix to suffice, and then I can amend and care for the soil over time.

[@James-kl7ig]

I used sunnyland 10-10-10 it's a good slow release

[@Angie-ep2ij]

I love that you shared this experiment. Speaking from the fact that I have killed thousands (littereally) of seedlings by over-fertilizing, and the evidence of crispy edges on the leaves, the seedlings needed much less fertilizer. I would have loved to see one with only water simply because plants make their own food, through photosynthesis, so it would probably still be alive. It would not thrive, but it is fascinating to see how long a seedling survives with only water. Thank you for your honesty. This is a great experiment, and definitely worth repeating.

[@miltonwelch8619]

Thanks for this very relevant video. I also thought that the amount of fertilizer per feeding was a bit skimpy, so that even with a nutrient based medium, plants if that size might still have required more food or greater frequency of feeding. I can't wait for your rerun!

[@shellyvlasic3584]

Awesome video. Learned so much. Yes redo this again with different medium. 😊

[@DiannasHomestead]

Thank you so much for sharing your experience with us. It's a learning experience 👍🏼

*Great experiment! it was very informative to see just how essential organic matter in the soil is for plants to survive. I'm so happy I used compost in my blueberry potting mixture otherwise I would have been toast... It would be cool if you made a video about what gardeners should use for their blueberry potting mix because when I researched it online everyone had a differnet answer and it was so confusing...* I got inspired to add blueberries to my garden from your videos on blueberries, and I bought the 25 gallon grow bags from your Amazon Store Front too. The potting mixture I used for my highbush blueberries was this: 45% GolfGreen Canadian sphagnum peat moss, 30% compost, 10% miracle grow potting mix 0.21-0.11-0.16, 10% miracle grow perlite 0.07-0.07-0.07, 5% high porosity HP mycorrhizae, and I also added some 4-10-0 GolfGreen bone meal, some jobe's organic 4-4-4, and some eleimental sulfer pellets. It was kind of a guess based on some articles I found online, hopefully it works out well, I'm also using miracle evergreen & acid loving water soluable food to give them a boost until the sulfer pellets kick in. What mixture would you have used? Would love to see a video on this! -From your Nova Scotia Canadian Subscriber :)

[@PassingTimeInPeachtree]

It’s nice to know that the manure products I buy and till into my garden soil are very important, more so than the fertilizers I use. I did use the bone meal this year and am having a nice harvest of tomatoes.

[@priayief]

For the last 20 years I've conducted at least two trials every years. I test potting mediums, soil additives, germination mediums and any else that gets me curious. The most similar trial to this one was to test two different potting mediums using Sweet Million tomatoes. One potting mix was Miracle Gro and the other was my homemade concoction that was primarily homemade compost, peat moss, perlite and Gaia Green 4-4-4. Both proved successful but the way they got there was quite different. Miracle Gro took a noticeable lead in size and density of the seedling. After about 3 weeks I thought it would prove the winner. But then, my homemade variety quickly caught up and maybe slightly surpassed the Miracle Gro. It was a good thing to know that I could be successful with either. I should add that I'm not looking for minor differences. At my level of production where I might get (say) 50 pounds of tomatoes one way and 48 (say) pounds another way, that doesn't matter to me. I'm looking for significant differences that I notice by simple observations.

Thanks Anthony. Thumbs up from a Long Islander living in Iowa. Hugs to Dale.

You're welcome! Dale sends his love 🐕

[@katherinegooch8147]

GREAT VIDEO!!! Can’t wait to see more experiments!!

[@danielleishman8648]

Notice how the tops leaves have died before the middle/bottom, where the water needs to travel the most distance. If it cant uptake water, it cant uptake nutrients properly. I have used water soluble nutrients with peat/ perlite and coco and perlite at least a dozen times and had completely healthy plants from seed to harvest.
