Oh NOW you tell me. Been battling blight and powdery mildew for weeks.

[@joeyossarian4689]

Hahaha right?!

[@Gardeningchristine]

They have the 1/2 gallon pump sprayer at dollar general for $4, and about $6 at Walmart if you can’t/don’t want to carry a whole gallon.

[@danarzechula3769]

My arthritic wrists thank you😂

[@coldwhitespring5004]

I used these two recipes that I found online for what was probably late blight on my tomatoes: 1 tsp baking soda, 1 tsp vegetable oil, and 1 tsp mild dishsoap for 1 liter of water, and a few drops of iodine mixed in 47/60 low fat milk and water. I alternated between these two, one spraying a week for each, and it worked!

[@TonyisToking]

I've been spraying my plants with epsom/sea salt and fulvic acid lately. I find it keeps the leaves very healthy by just giving it the trace minerals it needs. Fulvic is supposed to help with nutrient uptake into growth tips.

[@TonyisToking]

I also use Dr. Bronners as a surfacant. I think that helps prevent PM/Blight as well. Cause of pH, like you said.

[@AlissaPaige91]

Can we do some videos on gardning I'm containers on a budget? I live in an apartment complex and all my plants are out front of the building. I work 2 jobs and don't have much money to keep buying bigger pots etc. Going through a 2year long divorce where I used to have a huge garden at my old house. It's a huge change with different issues I run into. Thank you for all your amazing videos ❤❤❤❤

[@commonlaw5400]

If you someone who works in a grocery store or any place that makes cakes with icing-the icing buckets are perfect for container gardening. You should be able to get those for free. The Gardening Channel with James Prigioni and Next Level Gardening have container playlists. Luke may have one as well. Watch the curbs on recycle day-Kitty litter buckets are strong.

[@AlissaPaige91]

@commonlaw5400 thank you! I appreciate it. I've used 5 gallon buckets and mop buckets before but never thought of the kitty litter ones. I have a cat and have thrown so many away 🤦‍♀️

[@lulumchugh3908]

I must say, I'm a pretty new subscriber (within the past year or so)... and every video I have watched since finding your channel, has helped me tremendously. So much helpful information. Thank you. Admirable!!!!

[@Angela410R]

Thank you for the great information. I will certainly put this information to good use. I believe I've heard you speak of this prior to this video and put to good use although I have forgotten to do so this year, thank you for the reminder. Love, MIgardener

[@polaniecj]

Been asking for this video for years in live streams and comments.😅 glad to finally see it! Thank you so oooo much ❤

[@stephanieflowers2783]

Such great info!!!! I haven’t used ANY of these methods but have written all of them down for future use. 😊

[@kristinpagan2361]

I'm a pretty green gardener so I'd never heard of these 3 homemade sprays. Definitely not the aspirin spray. Something to remember for the coming season - I'm in the Southern hemisphere so spring has sprung. I'm just waiting for the last frost date to make it's visit.

[@AlissaPaige91]

Thank you! I needed this so much.

[@minivandreamin1789]

Great info! Thanks!!

[@lindap7983]

Always great information! Thanks so much!

[@victoriaturnershoemaker3723]

Thank you!

[@markkristynichols845]

Spot on, and n ALL THE THINGS!!! And oh how I was so ticked at myself when I killed my plants by spraying mid day-DUH! I should have known better! But so spot on as usual Luke! ❤ all y’all, Kristy in Missouri zone 6b😃🇺🇸🇺🇸🇺🇸

[@mommad1326]

Ahhh I AM subscribed!! 😮ok Luke I’m here for you and how timely for my lilac!

[@Iamfarashuu]

Blight got me this year. Thx

[@purplechris9480]

I grow brandy wine tomatoes. Guess what no blight. And they still are producing. Michigan zone 5.

[@Heatherhigleydrums]

Ooh I'm trying this in England...planted them out so late though as weather has been so awful here.. probably none will develop in time at this rate- I didn't realise how long they needed!

[@user-ic2ug8ys1z]

1st! 😃🌱🐢 Would this help blight on fruit trees also?

[@camicri4263]

Mine are dead, didn't stand a chance!😟 Thank you Luke! Hopefully I remember next year! Blessings 💕🤗

[@jackiehorsley9263]

sounds like Its really working for you Luke I well have to try It sometime

[@leighniece4482]

Great job! Any thoughts on how to control potato bugs besides picking them off every day?

[@jessicastead5544]

A strong chamomile tea works too!

[@tammy5590]

Luke could you use Dr. Bonners soap instead of dish soap? The calcium nitrate was the best thing I have heard so far. Thank you so much.

[@anniecochrane3359]

I will use the dr bonners soap givern it is free of toxins and biodegradable. And works in the same way as a dish soap would, by helping the mixture to stick to the leaves

[@MIgardener]

I love Dr. Bronners. Amazing stuff.

[@dustyflats3832]

Calcium magnesium citrate😊

[@terrivance8750]

Luke, Just an FYI. while it may be advantageous, for absorption purposes, to apply foliar treatments @ certain times of day, the belief that water applied to foliage will act as mini magnifying glasses & burn the leaves has been proven to be a myth by numerous university studies.

[@dustyflats3832]

Maybe. I noticed water burned leaves of bush beans and broccoli this year. The broccoli was under bug netting and gave about a 3 shade factor. I think if the temp from sun is a real scorcher it can burn.

[@terrivance8750]

Sun scorch can happen if it's too hot for a given plant, especially if the plant needs water. Misting the plant will actually help to prevent scorch by cooling it down in the heat of the day (per Jim Putnam of Horttube who's been a garden professional some 37 years).

[@nchestercountynews4955]

I don't get more than 2 seasons out of "cheap" sprayers.. and generally they only carry them in big box stores for 2-3 years and cant get replacement parts

[@bobert59]

any tips or tricks for pill bugs? they attack my seedlings and young plants and eat through the stem.

[@bobvanepps7517]

I suspect that someone has already asked this. I have used the baking soda treatment for years with pretty good success. Would combining two or even all three of these methods into one spray have any benefit?

[@lewidlivelewid]

Luke, what are your thoughts on whey as an anti fungal?

[@JuxstLer]

What about neem oil? I used to use baking soda but neem oil seems to help too. Still think baking soda may be stronger

[@mmac3333]

Will this also work for Rose bush as well 🤔

[@j.armstrongsr.7009]

The undersides of the leaves should be sprayed also imo. Good video

[@MIgardener]

Totally agree!

[@lidip8700]

He mentioned that & showed that in the video. .;)

[@RC-pf2qi]

Would that work for blight on apple trees?

[@robertavillella6485]

Most people say the aspirin has to be uncoated or it will gum up the sprayer. I have not been able to find uncoated here in Canada, anywhere. Any thoughts on whether they need to be uncoated?

[@bobjvet23]

Can you use them all in combination? I mean alternating between them

[@54cal54]

What about the 3 tablespoons of vegetable oil you used to use with the baking soda mix?

[@MIgardener]

That is entirely optional and can help the spray further stick on the leaf but I have found it to not be 100% necessary over the years.

[@susangibbons312]

Are there any garden-safe sprays you recommend for deterring DEER? Can't afford the best barrier options...

[@pquin1495]

Will these work for black spots on fruit trees?

[@claraobrien7185]

When should you start spraying…when first planted?

[@amysinger2201]

Had a what the heck moment when I realized we are already 2 weeks past our average 1st frost date up here in MT, so yeah, what the hay, lets spray!

[@barbaraengle768]

I have black spot on my bean leaves,some a little yellow with it,plants look good and are only about 2 weeks old..is this blight?

[@gang-ridertv5433]

Bruh, shoulda told us this 2 months ago!

[@debrak.6430]

How much water did u use with the 2 tsp? I have had really bad blight on tomatoes, squash....also powdery mildew on my nine bark shrub...the past couple yrs has been bad....

[@maryaliseherrera4057]

Am wondering about the frequency for all of this? Are you using all 3, all summer? Once a week? It seems like you could use 1 & 2 at the same time, or 2 & 3, but not 1 & 3? Just looking to be better prepared and armed with the right stuff for next summer!

[@valerieellison2483]

He's giving us 3 different options. The first 2 work better for blight, but could also work for powdery mildew. The third one works well for powdery mildew, but could also help with blight. I would just pick one and see if it helps after a couple weeks of using it. Then you can switch to a different one if you feel you need to.

[@anniecochrane3359]

just to clarify. is it 2 teaspoons of calcium magnesium citrate per gallon of water?

[@dustyflats3832]

It looked like 2 tsp per gallon. The sprayer wasn’t full the way he was swinging it.

[@lauriedavis4045]

Wonder if the acetic acid in the aspirin is the active ingredient?

[@lcunningham1776]

Salicylic acid

[@DeepwaterHomestead]

Will this work on roses or azaleas??

[@MIgardener]

It sure would!

[@stevetendrich398]

What about the baking soda, oil and a few drops of soap? You made that video, years back. Should I not do that method?

[@juliekovach9784]

You didn't say how MUCH water to add to the Calcium/Magnesium/Citrate to spray on the plants. How much?

[@elizabethpiela7389]

Do these work for fire blight on fruit trees?

[@MIgardener]

It can help!

[@Ribberflavenous]

So can you put all 4 items into a single spray?

[@lidip8700]

If you added an asprin, 1-2 Tbs of baking soda & Magnesium citrate all in the 1 gal of water, you would concentrate of solution by 3x because you added all 3 items that Luke said to add each to 1 gal of water. My question to you is, why would you think of doing that? There's no benefit, but you would probably kill your plants. It sounds like you would be creating a hot mess, to me. Lol Personally, I don't think it's a good idea.

[@ChrisKsGarden]

I looked online and they all have Vit D. Does your calcium magnesium citrate also have Vit D? If not, what brand do you use?

[@FloridaGirl-]

I just happened to screen shot when he was holding the bottle for my own reference. The brand he has is - Solgar. And yes it has vitamin D3.

[@ChrisKsGarden]

@@FloridaGirl- Thank you!

[@beahappy1today]

Do you think crushed calcium magnesium zinc tablets would be okay?

[@coldwhitespring5004]

Probably, since baking soda is also powdered.

[@MIgardener]

It could be worth a shot, I don't see how it could hurt!

[@beahappy1today]

@@MIgardener I’m going to do an experiment and see how it goes. There’s not much to lose because as you mentioned, powdery mildew will kill the plants anyway. If it goes poorly, I will use one of the other methods you mentioned for the rest of the plants. Thanks for your helpful videos and comments! I’ve learned so much more from your videos than with any other channel.

[@jenjoy4353]

Have you tried milk or whey spray.

[@jenjoy4353]

I believe there are ingredients in the whey that can actually get into the leaf cells and fight the fungal infection inside the plant.

[@luhas15]

Is earthworms enter home from indoor or nearby plants...I have potted somany...I saw tiny earthworms..from that onwards I'm very much worried 😩 plz help anyone,,reply

[@IAMGiftbearer]

I have not been able to find Calcium Magnesium Citrate without other stuff in it. Can you provide a link to it? Everything I have found has flavoring, Vitamin D3, Zinc, Boron, or Vitamin K in it. Not sure if those are safe for plants.

[@dustyflats3832]

His had D3. Won’t matter. Most magnesium supplements combine D3 and calcium as they work together.

[@FloridaGirl-]

The brand he is using is SOLGAR. i had screen shot the bottle. Yes, it has vitamin D3 in it. 👍

[@araceliadams34]

What caused the powdery mildew????

[@dustyflats3832]

Fuzzy leafed plants get it as soon as there are cooler nights, foggy damp conditions. The spores are always present and just takes right conditions.

[@t-bone6467]

Trying to follow the logic here. So if you start with weaker concentration and it's working increase the concentration for next time. If you start with weaker concentration and it's NOT working, increase for next time.

[@MIgardener]

start weaker, because if it works then you know you don't have to go stronger. If you go stronger and kill your plant then what was the gain in that? That's the logic.

[@magnuswootton6181]

hes putting metal into the plants!!!

[@PapaVikingCodes]

Sadly powdery mildew is not going to go away, it is a systemic disease and the powder is the reproduction phase. You have to treat it with something really nasty. Will try your concoction (CaMag), but hmm

[@lauriedavis4045]

Spores are endemic to the environment--they blow around in the wind.

[@purplechris9480]

You're so right. I grew black krim tomatoes and tried everything to save them. Still died on me.

[@purplechris9480]

Migardener sent me a free pack of homestead tomatoes. Their smaller but good producer with no blight.

[@lewidlivelewid]

Luke, what are your thoughts on whey as an anti fungal?
