Lack of oxygen and water. Thanks for your videos! We love the fact you add timestamps. We don't care for the JUNGLE, referring to online shopping.

[@EvolutionWendy]

My comment is late to the party, but-I often put COW MANURE under the cardboard to help encourage decomposition of the cardboard, and nurture the microbe & earthworm health, but I haven't done a time-lapse like you do, but my impression is that moo-poo helps break down the cardboard and decompose the weeds.

[@davewarrant8673]

I'd love to see another 6 month follow up! Maybe a short? I've seen videos where they've taken core samples of landfills going back to the 1950's and come up with newspapers that you can still read the date on! This leads me to believe that Oxygen has an impact as well.

[@christexaport]

Just wet it and put a little soil/compost/dead leaves/dirt on top of it.

[@ML-ce6zz]

Thank you for recording this experiment with the cardboard. My hypothesis is that if the cardboard had soil or mulch over it rather of having landscape fabric over it, it would have broken down much more significantly over 6 months. Would be another good experiment!

[@TheMillennialGardener]

I'm sure it would have, but I think the large sheets didn't help. After witnessing this, I think tearing it into small pieces or shredding it is the way to go if you want it to break down at a reasonable rate.

[@katiepayne2479]

You're right, my cardboard paths are covered by mulch and break down much faster.

[@groussac]

Iowa Zone 5a. Last October, laid same size or larger cardboard sheets around garden perimeter and covered heavily with leaf mulch. Cardboard still visible but on its way. Soaked through with melted snow. What I've noticed here is that fall mulch doesn't fully compost until mid to late June. Cardboard will be the same I'm sure. Needs water + heat. I'm really pleased with the barrier aspect of cardboard. Slow decomposition means it's in place for a long enough time to keep weeds from germinating. I would use it throughout the garden, but I'm afraid it wouldn't let the water through to the plants. Might also be heat issues with it.

[@johndoh5182]

He did two things wrong IF the intention was soil preparation. You are correct, you put down cardboard and not mulch, but compost on top. This is soil preparation for future planting. IF you just want to keep things from growing you can put whatever you want over the cardboard and any kind of mulch is fine. But soil prep means that worms and other life work their way up through the cardboard and pull nutrients down into the soil and that requires a compost that will feed living organisms. THEN, the critical ingredient, WATER. Yes, when you are preparing a bed with cardboard and compost, you need to make sure the soil is wet enough and you can't do that with a tarp on top, and in fact a tarp will block oxygen and CO2 from interacting with the soil and that's not good either. In other words I don't know what it is he thinks he was trying to do, but whatever it was the only thing I saw was death from no water.

[@bluemoon8268]

@@TheMillennialGardener … I think the cardboard needs to stay intact and overlap and cover any holes, no matter how small … it helps to wet the cardboard before layering the mulch on top …. An organic compost/mulch will break down the cardboard within six months, but it needs water/rain to interact with the mulch on top and the soil beneath it … the dead weeds should also decompose …

I'm a lazy old [74] guy - the cardboard goes down with all tape & labels, etc still attached. Toss enough dirt, weed harvests, or whatever on top to prevent the cardboard from blowing away on our occasional windy days. Sunshine, moisture & time will cause the tape & labels to loosen on their own so after many months when I have a moment I can easily rip off these nuisance materials & put them in my trash. I sometimes wish we were still allowed to have a burn barrel, but I'm a law-abiding good citizen [& the fines are outrageous...].

[@signsofautumn1]

@@ahcrxwhen it rains. The cardboard becomes suctioned together and it’s very difficult to separate. It causes a heavy matting for a long time and when it breaks down it keeps it dark and prevents weeds from popping through. As for laying down cardboard for barrier you need to get it wet for it to break down and cause a great weed barrier. Plus if you’re using as a true weed barrier with real plants. It causes it to breakdown faster and make a better weed barrier. Tip - while you’re laying it. Spray it with the hose every few yards so it stays in place until you lay your mulch down. You can use newspaper too, but you need to lay several layers at a time for it to do as well as cardboard

To make removing the tape and labels from brown cardboard boxes easier I highly recommend weathering them for a bit. The sun and rain will help to break the bonds making the unwanted materials far easier to remove than without weathering 👍

[@SarahS1214]

I’ve seen a lot of other people spray the cardboard with water before putting mulch on top.

[@johndoh5182]

Cardboard, compost on top. This is how no-dig gardeners/farmers often get a plot ready. If you have especially stubborn weed grasses then you could throw the barrier on top of the cardboard/compost. The compost on top of the cardboard is really what gets the earthworms and other life starting to do their thing and pulling stuff down into the ground, improving the natural biome underneath where you want it. Yes, they will also consume the cardboard by itself but give them more food with the compost and you get better results for the soil. This matters if you want to plant there. Because you just had cadrboard and a cover on top the soil underneath would have dried out, so it's not going to do what you thought it would do. So, preparation, like what people talk about and your experiment does nothing to suggest they are wrong, is they lay down cardboard, THEN put compost on top, THEN add water, because your soil can't dry out if you want worms to get in there, right? Funny thing about water and life, they tend to go together and that soil was bone dry.

[@fionaimison2042]

[@nadinehansen9241]

We have used loads and loads of cardboard around our yard with wood chips on top of the cardboard. We can buy a trailer full of wood chips at the dump for $35 and we raid dumpsters (with permission) for cardboard. We are on an acre, so it took a lot of cardboard and chips. It did an excellent job of suppressing weeds. It has been a few years now since we did our last loads and we need to do some areas again. We didn't bother taking off all the tape. If it came off easily we pulled it off but if it was stuck we left it. Eventually the cardboard breaks down and the tape remains and we pick it up and put it in the trash. I just got done putting down cardboard with landscape fabric where I wanted to grow potatoes in pots. For most weeds it's like magic. The exceptions where I live are bindweed, which will grow a long ways in the dark under cardboard or anything else to find a way out, and common mallow, which will also try to find a way around it. It's better to clear out some of the mallow before putting the cardboard down. I am in Southern Utah, zone 5.

[@tonistrother8266]

I have used cardboard with leaves over it with great results. Recently, I used it in a new location. I discovered that quack grass will crawl three feet to get out from under it. It also comes up in any cracks, gaps, or holes.

I put cardboard under about 3-4 inches of wood mulch in my pathways 2 years ago and it still isn’t fully broken down. The worms love it.

[@316lvmnoneofyourbusiness7]

Thank you!!!!! Finally, some validation. I've been gardening for about 35 years. Went through the whole gamut of using various methods to keep the weeds out. The best for me is a combination of newspaper and cardboard. Newspaper to put up a perimeter around the plant and cardboard on the rows. I use thin cardboard and poke holes into them for water and aeration. Then top the whole thing with bark mulch. This method keeps the bark from sinking into the dirt when it rains, the holes allow moisture to seep through but keeps the weed at bay. If I want to add more plants, I push the bark to one side, pull up the cardboard and plant. Works for me.

What a great video! Thanks for showing the "after" condition of the cardboard. I just covered my garden beds with cardboard that would have otherwise been waste. I put raised beds over the top, covering the remaining cardboard with mulch. I'm delighted to hear that the weed suppression may last more than just a season!

I’m in Texas. I put cardboard down in july for a melon patch. I didn’t cover with tarp or anything else. The cardboard is still there covering the grass. Yes, we had drought last summer but freeze and rain over the winter. I’m ok with the cardboard still there. I was only hoping for the St Augustine grass to be dead and easily removable. I have cardboard walkways around raised beds. Weeds are only at the edges.

[@TheMillennialGardener]

That's a really good idea - cardboard under the melons not only prevents rot, but I bet it blocks a lot of pests. I may have to steal this 😆

[@joantomlin7281]

I used cardboard to create a no-till flower bed. I laid down the cardboard just before a freezing rain, which welded it into a single sheet. I then placed chopped leaves on top and covered all of it with black plastic with some holes poked in it. I placed a light layer of mulch on top for aesthetic reasons. the following spring I transplanted by cutting into the plastic. Worked great! I think the soaking/freezing hastened the breakdown. By the way, I live in middle Tennessee

I think your theory as to why the cardboard hasn't broken down is spot on. Great analogy. The grass you're trying to kill out looks a lot like the stuff I have in the yard.

[@TheMillennialGardener]

The grasses here are tough. Due to the intense rainfall, hot sun and incredible pest pressure here, the native and naturalized plants and weeds are tougher than nails.

[@cherylhowker1792]

I’m well shocked it hadn’t broken down…. As we use it in compost pile and it disappears but we do writ it up and obviously the compost pile is kept fairly moist so that will break it down. Like the look of the new apple tree too. Glad you have managed to get something to add this year. Always nice to add extra fruit plants/ trees that will produce for years.

[@TheMillennialGardener]

It looks like shredding and burying is important if you want reasonably fast breakdown. Whole sheets don't go anywhere fast. This new apple tree was a red-fleshed apple called Pink Pearl. The flowers are stunning.

I put cardboard down around 4 small raiesd beds o suppress creeping buttercup in Nova Scotia Canada. We had one of the wettest summers on record but the cardboard didn't decompose a bit suring the summer. What it became was the daytime sleeping area fort hundreds of slugs, I was disposing of 50 p[lus a day through June July and August. The bonus was it also became a home for a family of red backed salamanders which also eat slugs. The downside is I can't walk on the carboard paths in case I squash a salamander. I notice nnobody checks the undersides of wet cardbaords, but they should. I don't suppose you will read this after posting it 6 months ago!

Did you place mulch on top of it? Thickly mulching on top of it should prevent those issues. You can also use a mulch like cedar, which is scented and repels some insects.

I have a small 48x12 in ground vegetable garden. For years most of my work was weeding. Last summer I used cardboard to lay down walkways in between rows of veggies. This cut down my weeding by 2/3. The weeding was a whole lot less. And the cardboard does thin out and will need to be replaced. I’ll toss the old into my compost box when we till this year. So, it does compost. Just longer than 6 months.

[@brendamontanye9877]

My experience has been different. I have used cardboard in my yard for many years. Most recently I have used it layered 2-3 thick with a thick layer of wood chips on top. The first year I do this on my garden paths the weeds are still likely to come through, and the cardboard is completely gone the next year. My backyard garden will just get cardboard patches and another layer of chips this year, but my farm garden will need to get the whole 2-3 layers of cardboard and a thick layer of woodchips. It is still worth it to me (at age 65 and digging my own chips from the town pile) but I do have some landscape fabric for quick cover if spring springs too early for me to complete the task. I just remove the plastic when I get enough supplies to do the job.

[@theekim6625]

If you put soil over it, the extra humidity would have allowed more break down. You basically put a tarp over the cardboard.

Thanks so much for your channel. I’ve used your recommendations to great results. I live in Raleigh, NC (zone 7b), and I’m planning to try the satsuma citrus and dwarf banana trees in my yard starting next summer. I use cardboard as a weed barrier in my food forest and gardens. It needs to be wetted when placed and needs to be watered by rain in order to break down. It feeds the soil (worms and pill bugs, a.k.a. rollie polies, really enjoy it), and it will last for a few months before fully breaking down, even over winter. Mine is under a layer of wood chip mulch.

I've been experimenting with using thin pieces of cardboard in some spots of my garden and also using the brown packing paper I get when I order stuff from Chewy for my cats in other spots of the garden. I also have some rolls of brown paper that is normally used for putting down when you paint stuff. I haven't used the weed barrier material though. Keep in mind I'm a first time gardener, so EVERYTHING is an experiment for me at this point..haha! I figure that if the weeds can't get any sunlight, they probably won't grow. When I use the brown paper, I fold it a few times until I can't see sunlight through it, then I place it wherever I don't want weeds and I cover it with about two inches of mulch. Along the edges of my flower garden, I did this and then put a layer of river rocks on top of the mulch- mainly for decoration, but also to prevent even more sunlight from getting to the weeds. In spots where I used the thin cardboard, I wet the pieces before placing them and then covered them with the mulch. I figure it will help the cardboard to break down faster and offer some moisture for the soil and the creatures that will break the cardboard down further with time. So far no grass or weed sprouts! Yay! It's only been two months, so we'll see how everything turns out as time goes on. But the parts where I have only mulch...I'm pulling unwanted grass sprouts out almost everyday eventhough I have about three inches of mulch in those spots. I can say that I prefer using the paper because it's easier to form fit around corners or weird shapes- It's just easier to use in general. I've had a peek under the mulch covered paper and the weeds are indeed dying under there. That's a good sign! Same with the areas where I put the cardboard. No sprouts and lots of dying weeds! So far so good! You just happened to pop up in my feed this morning. I'm subscribing and am about to go watch more of your videos. I wish you a most lovely day!

Wet the cardboard thorougly when it's in place - this is essential to help the cardboard to breakdown and provide a great food resource and home for worms. Weed mat and/or/ mulch on the top as desired.4.If preparing for growing, lay compost on top of the cardboard before mulching. Any weeds which appear are easily pulled out while they are tiny.

It takes a long time for the cardboard to break down. I helped on a community garden/food forest and we placed the cardboard in the fall and then in the spring planted the area and added drip irrigation. It needs a lot of moisture to breakdown. I had to cut through the cardboard to dig holes for plants. Even three years later some of the cardboard is still underneath.

[@myurbangarden7695]

I just tried your cardboard hack for around my garden beds.

[@TheMillennialGardener]

It works. It takes a long time to break down.

[@cynthiahelmich3762]

i add soil and mulch over my cardboard and it is completely composted by the next season. i use it as a natural weed barrier and the cardboard encourages worms for some great soil health :) i have a couple of areas where i dont get any weeds. i just add some new wood chips as needed. i dont even fertilize said area- whatever i plant thrives, even planted closely together. thanks for always posting great videos!

[@naningkikayintown6432]

Yeah i hear yah. I like that kind of gold. Thanks for sharing your ideas.

[@JulianJP21]

Thanks Friend 💪👍as always ...this is one of the best gardening channel!!

[@TheMillennialGardener]

Glad you enjoy it! Thanks so much!

[@MrStringybark]

You did say that the cardboard had to be wet for it to decompose.

[@juliewholohan2850]

As always, extremely helpful 👍🇦🇺

[@rickwashek478]

I think if you would have went the cardboard down and sprinkled some top soil on it it should have broken down faster.

[@TheMillennialGardener]

I soaked the cardboard down very well when I placed the weed barrier on it initially. But, it has been fairly dry (for here, anyway). I think leaving it as whole sheets on top of the soil line is going to take forever to break down no matter how much rain you get. If you want it to break down quickly, I think shredding it and burying it is the way to go.

[@stevenrodwell8883]

I ment, wet the cardboard first

[@ANGIEB52]

Right it will break down faster with compost or manure placed on top especially with the plastic because that will keep it warm and create moisture between the layers … almost the same as ripping the cardboard into pieces and putting it in dirt . 🧐🧐

[@leliam.cleveland528]

Great information.Thanks.

[@chicao8784]

Thank you for your experiment very helpful..

[@ToddSmithPartners]

Perfect timing. We’re here in Atlanta. Thanks

[@TheMillennialGardener]

You're welcome!

[@fitgirlyz8339]

That was very helpful thank you so much. I will definitely try it with the cardboard.

[@eleanorstegall-hughes1447]

I have used cardboard in the past. But needed to anchor it. I learned about gasketed garden staples. I hope to find them. Definetely going to join you. Great infor

[@user-kd5ig3vc3s]

Old rugs work too

[@philisbramlett6890]

This was a great experiment as a weed barrier ! It Will Break DOWN IF; WET IT DOWN FREQUENTLY to encourage breakdown sooner and Worms will break it down for you too ! Remove ALL PLASTIC Tape , Labels On The Cardboards to breakdown! ! Plastic does not breakdown .. Thank you for sharing !

[@sylvia10101]

This is great information! Thank you MG!😊👍👍✌️

[@TheMillennialGardener]

Glad you enjoyed it!

[@1Ggirl1959]

I have used several layers of cardboard with great success in my garden. I breaks down a lot faster in a wet humid climate. The only problem I has was little termite looking bugs... same for wood chips. the was in sw GA - hot humid climate

[@Deb11-11]

Thanks for the fabulous idea!

[@TheMillennialGardener]

You're welcome!

[@gratefulketo2211]

In my area, I use cardboard for most garden beds. It works reasonably well. I was forced to resort to commercial grade landscape fabric for my front flowerbeds. I have a weed called. “Mare’s Tail”. It had no trouble piercing through the cardboard. Some of the quackgrass also was able to get through. The landscape fabric did the trick! All the holes were made by using a torch. This kept the edges from fraying. I covered the landscape fabric with pine bark mulch. It created a visually pleasing surface that does not break down as easily as other mulches.

[@gloriatucker6158]

I also have gangster weeds and grass. It seems to just grow through things. This year I used 6mm black plastic, no weeds, plants are growing. I was afraid to use it before because I thought no air and water would get to the plants roots. They seem to be fine. My side garden has weeds all over.

[@MariaReyes-te7lk]

Excellent information..Thank you..

[@MnNorthstar2010]

Thanks for your update on weed barrier! I'll be using cardboard in my garden spaces to prevent weeds!!😁🇱🇷🤗

[@TheMillennialGardener]

It really does work, and it clearly lasts a long time!

[@lenethharris-johnson8238]

An excellent video. I intend to put this into practice this season. Thanks for sharing.

[@TheMillennialGardener]

You're welcome! Thanks for watching!

[@jaysonvance594]

I put wood chips on my cardboard in the fall and it's already gone. Mulch and moisture are your friends when you have cardboard. You could even put compost down right on top of it. It also helps the cardboard lay flat if it's already wet.

[@lauracrazyhatdiscoveries8429]

Thnx for all the great content! 🎉

[@TheMillennialGardener]

My pleasure!

[@arewealone9969]

I’ve used cardboard for well over a year, works great. I’ll have to use weed mat on top like you did.

[@DaveCurrieDesigns]

Never even thought of using carboard in my garden and landscaping - definitely gonna give it a try. Great channel 👍

[@Braedenfish]

It is excellent. 90% of landscape fabric uses should be replaced with cardboard .... like say except commercial grade used under rocks. The thin stuff is useless waste of money. 2 layers of cardboard is magical.

[@kenhunt5153]

OCC has an extensive recycling rate across the Country. Using exposed weed fabric raises the temp of your garden. To stop rhizomes overlay the cardboard by six inches. Use three inches of mulch on top.

[@rhondafountain648]

Thanks for showing the experiment. I had a friend who used the brown wrapping plain paper as well as cardboard to kill the weeds, then covered with landscape covering. i really want to get rid of grass & have just a stone covering area.

[@janjans1178]

Ive watched other videos where the cardboard is sprayed with water which gets decomposition started 💡

[@snowhite38]

I purchased a home last June, the back yard has no grass and nothing but weeds. I was busy unpacking and getting the house organized so I didn’t do anything about the weeds. I just kept cutting them down so my little beagle could use the yard. Over the winter I made big plans for the yard, and was so excited until I found out the weeds are Japanese knotweed (which is growing through my foundation). They grow through rhizomes and spread like wildfire. After consulting with the Ministry of Natural Resources (in Ontario) there are few things known to kill it, but one is to put down black plastic for 3-5 years to kill it. Now that I’ve found your video I’m going to put cardboard down first, and then the plastic as you have done. I’m hoping it may speed up the process. Thanks for the great idea.

[@mamtajaya6457]

Wow brother. Just the information I needed. Amen. Thanks. Gif bless you with great knowledge 🙏

I’m going differently do this, Thanks for this info

[@donnacaputo3078]

Very informative. Thanks so much.

[@TheMillennialGardener]

You're welcome!

[@michellewilding9698]

Wow. Good info!! Everyone is using cardboard in their raised beds as filler and not shredded. 😮

[@TheMillennialGardener]

If you want it to break down, definitely shred it!

[@SylvieLaflamme]

Very GREAT video! Very helpful for me. Thank you so much! God bless you.

[@TheMillennialGardener]

[@jeffreyanderson5304]

I'm glad I subscribed to your channel I learn a lot from you about to do when growing a garden

[@TheMillennialGardener]

I'm glad to hear that!

[@josefinachua9153]

You did a good job !i really enjoy learning this video.

[@AntLive29]

Thanks

[@suissejetaime7]

Up here in the damp PNW, I get 3-4 weeks from cardboard on the ground before it starts falling apart!

[@victoriao1828]

Thank you

[@lynb4043]

Yes I’ve been using cardboard also. When it does breakdown , all that remains is the tape strips , so I’ve learned it’s better to remove that

[@simplymejourney998]

Thank you..

[@dawnmuller8987]

I put down cardboard for my new no till bed and the rain and topped with leaves and pine straw and it is almost completely broken down from when I put it down Jan 5th. I think more water and the somewhat impervious landscape fabric made a difference in your breakdown.

[@aovoonthefarmsouthernillin3687]

Nice video.

[@topcat4747]

Thanks.

[@samarmenio2230]

So everything you've said is totally accurate...I might just add that if you can find dew worms and include them prior to laying them down on to the dirt...they will add to the deterioration of the cardboard...and yes moisture is also critical!!

[@jotv7224]

i like covering the cardboard in winecap spawn and wood chips. card board unshredded can go on for a few years before it starts to break down.

[@troyb.4101]

I do container gardening, I hope the card board last a long time. When it's wet I plant right through it. only the plants I want hopefully survive , without weeds.

[@christinawebb3016]

My neighbor uses newspaper under his mulch. I use weed barrier and I have weeds popping through. I might try it.

[@jamessmith5021]

Great job excellent speaker knowledgeable Great ideas!

[@TheMillennialGardener]

Thank you!

[@SusanDwyer-mp6yv]

I use newspaper and cardboard,mulch on top in garden beds, my granddad born 1900 used paper for decades

[@oshead]

You've had drought for 6 months. I've put cardboard down below wood chip on the paths and organic matter in the beds, side by side and they were both almost completely gone after about 9 months. Maybe sooner but I didn't check. I do live in Ireland and we have a very wet climate.
