Sadly, I have 11 black walnut trees that line the entire length of my one acre property. 8 years ago i planted my first garden only 15 feet away from the tree line and it took me two years to figure out what was happening to my plants. Moved my garden to the opposite side and now I am 6 years into having a more successful garden! Unfortunately I still battle squirrels burying the walnuts in my garden
I had always noticed that the trees nearest the walnut tree in my parents’ cherry orchard were the lowest producers, but I never knew why! I love coming here and continuing to learn, even after having been in gardens and orchards as a hobby for years! Thanks for helping me garden smarter!
I was aware. My neighbors have their fence lined with about 10 black walnut trees. Since moving my raised beds to the back yard, they are about 25' from the trees. I also garden in 5-gallon buckets...tomatoes, peppers and egg plants have done well. For being such a hot summer (6b), the garden has been a success. Thanks for all your help.
We have three HUGE black walnut trees in our back yard and yes I did know about the juglone effect on some plants. I mainly grow hosta beneath them as they don’t seem to be affected at all. I did do some research on what was able to tolerate juglone before I planted around the trees. 🥺🌺💚🙃
I would like to thank you for all of your videos. I have learned so much! I only found out about a week ago when I had to have a Black Walnut cut down & I was going to use the mulch in my garden but the tree removal guy told me about the effects it would have on my garden. This is my second year gardening and both have been very good. I still have two very tall Black Walnut trees so I going to have to find a different for my new flower beds.
North just Black Walnut trees. Butternut or White Walnut trees also produce Juglone. I believe all walnut varieties produce it to some extent. I do raised beds with a root gap below the bed to ensure the trees don’t send roots up into the beds. Think beds on short legs.
My neighbor has one on the fence line. We had two small ones in the yard that we had removed when we had some other trees removed. They grow like weeds. Yes, in my garden too, thanks to the neighborhood squirrels.
We have acres of black walnuts, asparagus grows, raspberries,. Use a raised bed! native medicals do well...elderberry, pawpaw, spicebush, aronia, st john wort. Ty! Ty! I have been experimenting with this. !,
I knew Black Walnut was a problem and the squirrels have been planting them for years in my yard. They are one of the most beautiful and fast growing trees around. I asked my husband to remove some of them, along with some boxelders that had grown to shade around my veg garden a couple years ago and he chipped up the wood. I have been afraid to use the wood chips. I am very pleased to now know that I can use those beautiful straight trunks as boarders and the wood chips as mulch and that it takes less than a full season to remove the danger. Thanks so much. I love your videos. Keep um coming. Deb, from Wisconsin
My husband and I have had issues growing tomato plants for years. They start off looking really healthy, but shortly after fruiting and growing to medium height become very stunted and start to wilt. Same pattern over and over again, which we assumed was due to disease or lack of nutrients in our soil. I stumbled upon the relationship between the black walnut tree and nightshade plants this year by complete accident. We'd been getting the nuts dropping into our yard from our neighbor's tree for years but had no clue what they were. This being the first year I got very curious about plants and gardening, I finally looked up what the fruits were and voila! Not only discovered we'd been living next to a black walnut tree all along, but also cracked the code on why our tomatoes routinely struggle so much. Disappointing, but very enlightening. Perhaps not surprising, our most successful tomato plant was in a brand new raised bed we'd added to the garden this year. Next year, we plan to try growing tomatoes in containers.
I had no idea about black walnut trees. But I was thinking of planting some sort of a nut tree in my garden next year. Thanks for the info. I learned a lot.
I have 3 huge black walnut trees that have been there for over 100 years (it would take 2 to 3 people to hug it) the neighbors also have the same- we live near the river in an area that was an old canal system. I’m glad for the confirmation that my garden is far enough away.
@@Dirt-Fermer I live in swamp land and they don't care for wet feet. So I just travel towards the Blue Ridgeline a few hours and pick from the wild. Pecans do well here, though, and I do enjoy those!
I have black walnut trees in my yard and did not know about this issue. I'm just lucky I planted away from the trees. Thank you so much for all the years of knowledge you have shared with us. ❤
Ha ha I had one in the middle of all my gardens but the hubby wouldn't cut it down, fast forward the hurricane took it down this year. Weeeee soo happy. One day I'm going to get my hands on those walking onions. You always sell out before I do. Lol I've always known for 10+ yrs.
I used black walnut shelling to compost into my beds at the end of the season last year and wondered why my grape vine and blueberry bush was so sad this year. Should I just get new plants and soil? Edit: I realized you said it doesn’t stay there forever🙌🏻 I did look into it after I realized my plants were dying back in early -mid summer, and found the information you provided except that it eventually makes its way out of the soil so glad there. It’s good to see someone bringing light to it on TH-cam though!
Black Walnut roots and nuts are the 1st/2nd highest concentration of Juglone, there is Juglone throughout the tree but it is comparatively much less, because it is an organic compound, exposure to heat/air/moisture speeds up the breakdown. BW is Hardwood, which means the composting process will take longer, you will need a hot compost for the leaves(I make about 2yrds of compost from my BW leaves alone)
Black walnut husks/shells are great to mulch pathways. The juglone helps keep the paths free of weeds - as long as you're not trying to grow anything sensitive right next to the path.
I did not know this. My neighbor had a huge one in their yard. Toms were planted far enough away I guess, because I never had any problems with the garden. Thank you for this info, because I really had no clue.
First time I heard about the toxicity of black walnut roots & seeds. Thank you for that. Walnut trees are everywhere on my property. Thankfully, my gardens are at least 25 feet away.
I just figured this out last year and moved my garden this year. I had worked several years wondering what the heck I was doing wrong! Much better results after the move. I still kept that was my garden and used it for melons this year.
I thought it was something that the tree dropped or pollinated from above. My tomatoes did bad this year, but great last year. Also, I have a raised bed... so I'm thinking I over filled the bed (which I'm famous for) or i amended it with hot soil in the spring because the tomatoes and peppers and lettuce are all happy now. Thanks for the reassurance!!
I was aware. My neighbors trees are close to my garden, and so I haven't been able to grow my beautiful tomatoes there anymore.😢 Thanks for this enlightenment for those who need to be aware of this.
I can't remember how long I've known about this, but since we bought our property 4 years ago with a giant black walnut in the back yard and more in the woods, I have been researching what to grow around them that I can eat. Collecting and planting black raspberries, paw paws and mulberries are some of the things I have been working on in the vicinity of the black walnuts. I also cut down the one who was 15' from the veggie garden. Not to disparage the black walnut though. The nuts are great. I harvested and dried quite a bit last year and give a wheel barrow or so to the squirrels every year.
I have raised beds that are under the drip line of about a dozen walnut trees. the suppressive impact on nightshade plants is unbelievable. I've almost given up but this year the tomato production was extraordinary. go figure.
This was interesting. I plant in 5 gallon buckets, but the squirrels bury their nuts in them. I'll have to keep an eye out for black walnuts. Makes me wonder if that's why certain plants weren't doing well early in the season (or if it was just the ridiculous heat) & doing well now!
Great video. My neighbor planted a black walnut tree a few years ago and its maybe 20 ft away from my garden. The Squirrels take the walnuts and bury them in my compost. It took awhile to realize that it was effecting my garden. And, to add to that this same neighbor has a lawn service spray every month right up next to my fence (i have asked repeatedly to not spray that close-but falls on deaf ears and now Im the Karen next door)😢 Im almost to the point of giving up. 😢😡
I knew they were bad for gardens but didn’t know about the soil part. Would love to get rid of mine do to the over abundance of nuts. Even the squirrels can’t keep up with them. Last year we took 4 wheelbarrows full off our yard in order to mow. Trying to find someone that would buy the wood to offset the cost of having it cut down.
Squirrels keep planting black walnuts in my beds. The dang tree keeps coming back. So I’m just moving the bed. On another note, what is this contraption you are sitting on? I usually sit on the ground or on the folding one (feels like it’s going to fall over so I use it for kneeling). This wheeled thing might just be the ticket!
Perfect timing! I just watched a video like last week or so (might have been here lol) where someone something about either not using mulch or compost (can’t remember) from a black walnut tree and I was so curious as to why BECAUSE I HAVE A BLACK WALNUT TREE NEXT TO MY GARDEN! Thanks for the info!! Now… if you could do a video on what to do if your whole yard is covered in mold and fungus… seriously… sooty mold, black mold on tomato plants, black fuzzy mold on basil plant, shot hole disease on every wild fruit tree, downy mildew on zuchinni and pumpkin, and more! I feel like I just can’t recover from this. I didn’t know I had it until I started gardening THIS YEAR and paid attention to everything.
New to gardening, I didn’t know about this tree. Thankfully I don’t have one but I am also doing elevated beds on my deck because I don’t want to strain my back with an in ground garden.
I did not know about black walnut trees. My neighbor has a row of 6 to 8 trees that are far enough away from my garden, however, the squirrels love to take the nuts and bury them in my beds. Unfortunately, I don’t find them until later. Your information is good to know! thanks Luke.
Did not know this, and my husband is an arborist of 47 years. But we've never had a black walnut tree in our yard, so he had no reason to tell me about this.
I had no idea, it was an interesting video. We had a black walnut tree in our front yard and our garden was in the back growing up. I'm that weird person that loves the smell of the green walnut husk around the nut lol.
I have my garden next to several black walnut trees. I have been gardening since i was a teenager. I never knew about this juglone problem. In my defense I have only been next to these for 20 years. Now I know why my plants just won't grow well at that side of my garden. My other problem is I have a 50-foot-tall pine tree on the southwest part of my garden. I do know that it won't grow certain crops there. Blueberries like it. Thanks for doing this video. Cecelia
When we built our custom home, we used all black walnut for the wood trim and every piece of furniture, cabinet, built-in bookshelves, pantry, crown molding, baseboards, everything. The whole house is black walnut. We even have walnut butcher block countertops. I am a woodworker and we used my shop here on the property to mill, surface, cut, shape and sand all of it. We generated cubic yards of black walnut sawdust, all of which, we added to our compost bays to break down into compost. And in a few months, after it had been broken down to black gold we put all that compost directly into our garden beds. We never had any problems growing our fruits and veggies in that garden though. So, I guess the juglan breaks down in the composting process? Or maybe there isn't as much in the heartwood as there is in the roots? Is it mostly a root exudate? I don't know. But in our experience, you can add a whole lot of black walnut sawdust to your compost and then to your garden with no ill effects to plant growth.
I knew about juglone. I didn’t realize that mulch was safe. That was good to know because I’ve been hesitant to use chip drops that I didn’t know what made them up. Thank you
my mom had a black walnut near a bed that was mainly roses and flowers, that didnt do well. we talked about the possibility of the bw affect. good to have it confirmed. Also wondering if maybe spreading bw skins in an area where you want to suppress growth of invasives might be an idea. our house had so much goutweed when we moved in. goutweed creeps to the edge of the borders where it gets the sun. maybe there, if you're content to not have much grow there.
My understanding is that they have small amounts but decompose quickly. When gathering up leaves in the fall for mulch, I steer clear of the walnut, but don't sweat it if I get some in the pile.
The University of Wisconsin told me the as tall as the tree thats how far the juglong is in the soil and it stays in the soil for many years. It killed 300 of my roses.
I have a black walnut tree in my herb garden that has been causing problems to the point that I've given up trying to plant much of anything anymore until i can cut it down. I have found calendula grows well. I mulch everything with the leaves from my yard, do you know if the leaves have juglone in it?
I found out the juglone issue after I planted 3 juglans Regia trees in my property. Now I'm looking for an isolated spot to move them over in order to protect not only the annual garden but the fruit trees
Hey! Luke, I am so happy you had this topic. I never knew this about the black walnut. I don't have one near my garden but I collected bags of leaves around town to put in my garden as compost. It turned out that a couple of bags had the nuts or shells from nuts in them and that end of the garden didn't do very well. It was where my peppers were. 😢 Even before I watched about this information a couple of weeks ago I started raking them out just cause I didn't like them in there but now with your information I really need to get the rest out. But my question is, what about the leaves from a black walnut tree, do they also cause a problem with how your plants grow? Thank you for sharing and happy gardening!
The squirrels are really good at "planting" walnut trees in my garden. I worried about the leaves getting into my compost location. Haven't had any issues though.
I absolutely love walnuts, all varieties. I knew you couldn't plant non-native and even many native plants below them but it's good to know what we can. Hopefully people remember that the walnuts themselves are delicious crop, assuming they like walnuts LOL I know everybody doesn't.
I'd say more than 5 percent. I didn't know this til last year and I had a garden 2 years before that. Thank you raised beds. I had a few stunted pepper plants but everything else was fine. They still grew, just took about 2 months for them to start growing even when the warmer weather hit.
I have a HUGE black walnut tree in the middle of my yard. I started my garden right under it so it could provide some afternoon shade from the Texas heat. I didn’t know about the jugalone issue until a few months after I started my garden. Luckily, I have about 25ft from my nearest bed to the base of the tree so everything’s been growing well. The issue is when the fruit drops or when the squirrels bury them and I’m stuck picking up hundreds of fruit off the ground. Since the tree is so huge it would cost a fortune to cut it down so I guess I’m stuck with it for now…
My dad taught me about black walnut trees' effect on tomatoes and peppers when I was a kid. I just moved onto 2 1/2 acres, and there are black walnut trees everywhere! My neighbor told me that people would pay me to cut my large black walnut trees down because of the value of the lumber. I may consider this for a couple that are really close to the house.
I lost my in ground garden last year. We didn't realize it was our neighbors black walnut tree. We put in tall raised beds and brought in 5 yards of new soil this year. The night shades did well. Will the raised beds continue to keep the plants away from the roots.? We plan on adding some new soil on top every year.
I have a few black walnut trees within 30 feet of my backyard, so the roots aren’t the issue. My problem are the squirrels burying the walnuts in my garden. No, I didn’t know about the relationship between a garden and a black walnut tree, and thank you for posting this. Now a lot of things garden related make sense - there have always been black walnut trees close to every garden I’ve ever known, and I always figured it was the residual fruit at the base.
We have one huge walnut in the back where my garden is, and the garden does fine, so it must be far enough away. I only learned about the effect of juglone on surrounding plants this year. There are plenty of black walnuts on another part of my property that I can gather for medicine and food.
I heard rumors about it, but since I had none around, I didn't look any more into it. It is good to know because I love walnuts LOL And now I know I can't plant it near anything that I'm going to grow basically just to be on the safe side. I prefer English Walnuts though.
I have 8 of those trees. I have 2 ft high raised beds. My problem is the squirrels are trying to plant a forest. I pulled seedlings out of my Greenstalks this year.
I was aware of the problem because I experienced it in my garden. Was unable to have stump removed and now it's growing suckers. How can I kill the stump and roots??
Hey brother my frost date is fast approaching. Y'all going to ship that garlic out any time soon? I love the videos and your products but that shipping time is sllllloooowwwwww
I was aware but didn't realize how fast the residue wore off. I grew up having to pick up walnuts from about 50 trees in my grandma's yard every day so she could mow and not have little shooting missiles 😅 to dodge I One question though, do the leaves contain the poison also? Thanks Luke for so much gardening information
I knew the nuts were toxic to animals but didnt know about the roots. Explains why my tomatos and squash have done terribly since we moved. Would planting in fabric pots help?
I did know this about black walnut trees but I didn't know about the mulch not having the same. Thank you!
Sadly, I have 11 black walnut trees that line the entire length of my one acre property. 8 years ago i planted my first garden only 15 feet away from the tree line and it took me two years to figure out what was happening to my plants.

We knew from experience but did learn from you that you don't have to abandon the idea of a garden if you have some space 👍💝
There are 5 black walnut trees in my small backyard. I almost put the leaves in my compost but I was tipped off.
I did not know this. My neighbor had a huge one in their yard. Toms were planted far enough away I guess, because I never had any problems with the garden. Thank you for this info, because I really had no clue.

English walnuts are sometimes grafted to black walnuts stock because it's hardier. This will still cause the juglone problem

The hulls are great natural herbicide along fence rows. As well as other places.

Story of my life at this point!

You could mention pecan and hickory trees that also secrete juglone.

Wasn’t aware , thank you.
I was aware of the issues with black walnut, we have a forest of them behind our property.
Love the walking onions!
I knew black walnuts were bad for the garden but not much beyond that; good to know the bark isn’t a problem.
I was NOT AWARE that k you sir 🙌🏻
I knew they were bad for gardens but didn’t know about the soil part. Would love to get rid of mine do to the over abundance of nuts. Even the squirrels can’t keep up with them. Last year we took 4 wheelbarrows full off our yard in order to mow. Trying to find someone that would buy the wood to offset the cost of having it cut down.
I know in Indiana walnut trees can be sold. The wood apparently is valuable for cabinets.
You can sell the nuts. Some people buy them.
Thank you for the great information

My garden is in containers but I have some nice ornamental plants and trees close to 2 walnut trees that have been planted by squirrels 🐿
Thank you for the great information about this!
I had no idea about the black walnut trees. Thanks for the information!
I didn’t know. Thank you!
What about leaf mulch or composted leaves that have some black walnut leaves in it?
No Juglone
New to gardening, I didn’t know about this tree. Thankfully I don’t have one but I am also doing elevated beds on my deck because I don’t want to strain my back with an in ground garden.
I knew about juglone in Missouri

I knew about juglone. I didn’t realize that mulch was safe. That was good to know because I’ve been hesitant to use chip drops that I didn’t know what made them up. Thank you
This was new to me! Thanks Luke!
my mom had a black walnut near a bed that was mainly roses and flowers, that didnt do well. we talked about the possibility of the bw affect. good to have it confirmed.
Also wondering if maybe spreading bw skins in an area where you want to suppress growth of invasives might be an idea. our house had so much goutweed when we moved in. goutweed creeps to the edge of the borders where it gets the sun. maybe there, if you're content to not have much grow there.
what about the leaves?
My understanding is that they have small amounts but decompose quickly. When gathering up leaves in the fall for mulch, I steer clear of the walnut, but don't sweat it if I get some in the pile.
The University of Wisconsin told me the as tall as the tree thats how far the juglong is in the soil and it stays in the soil for many years. It killed 300 of my roses.
So sad!!😢
I have a black walnut tree in my herb garden that has been causing problems to the point that I've given up trying to plant much of anything anymore until i can cut it down. I have found calendula grows well. I mulch everything with the leaves from my yard, do you know if the leaves have juglone in it?
I found out the juglone issue after I planted 3 juglans Regia trees in my property. Now I'm looking for an isolated spot to move them over in order to protect not only the annual garden but the fruit trees
Hey! Luke, I am so happy you had this topic. I never knew this about the black walnut. I don't have one near my garden but I collected bags of leaves around town to put in my garden as compost. It turned out that a couple of bags had the nuts or shells from nuts in them and that end of the garden didn't do very well. It was where my peppers were. 😢 Even before I watched about this information a couple of weeks ago I started raking them out just cause I didn't like them in there but now with your information I really need to get the rest out. But my question is, what about the leaves from a black walnut tree, do they also cause a problem with how your plants grow? Thank you for sharing and happy gardening!
The squirrels are really good at "planting" walnut trees in my garden. I worried about the leaves getting into my compost location. Haven't had any issues though.
I absolutely love walnuts, all varieties. I knew you couldn't plant non-native and even many native plants below them but it's good to know what we can. Hopefully people remember that the walnuts themselves are delicious crop, assuming they like walnuts LOL I know everybody doesn't.
I'd say more than 5 percent. I didn't know this til last year and I had a garden 2 years before that. Thank you raised beds. I had a few stunted pepper plants but everything else was fine. They still grew, just took about 2 months for them to start growing even when the warmer weather hit.
Great video!
I have a HUGE black walnut tree in the middle of my yard. I started my garden right under it so it could provide some afternoon shade from the Texas heat. I didn’t know about the jugalone issue until a few months after I started my garden. Luckily, I have about 25ft from my nearest bed to the base of the tree so everything’s been growing well. The issue is when the fruit drops or when the squirrels bury them and I’m stuck picking up hundreds of fruit off the ground. Since the tree is so huge it would cost a fortune to cut it down so I guess I’m stuck with it for now…
Paw Paw trees, elderberry, and autumn olive seem really happy around Black Walnut, so maybe consider them for a juglone absorbing barrier, too.
My dad taught me about black walnut trees' effect on tomatoes and peppers when I was a kid. I just moved onto 2 1/2 acres, and there are black walnut trees everywhere! My neighbor told me that people would pay me to cut my large black walnut trees down because of the value of the lumber. I may consider this for a couple that are really close to the house.
I had a squirrel plant a walnut in my raspberry patch. I'd like to give the sapling to my inlaws but it's pretty late in the season.
I lost my in ground garden last year. We didn't realize it was our neighbors black walnut tree. We put in tall raised beds and brought in 5 yards of new soil this year. The night shades did well. Will the raised beds continue to keep the plants away from the roots.? We plan on adding some new soil on top every year.
I didn't know that.
I am aware, thanks for more detail.
Never knew that. No worries for us but Great info. Thank you Luke!
I have a few black walnut trees within 30 feet of my backyard, so the roots aren’t the issue. My problem are the squirrels burying the walnuts in my garden.
No, I didn’t know about the relationship between a garden and a black walnut tree, and thank you for posting this. Now a lot of things garden related make sense - there have always been black walnut trees close to every garden I’ve ever known, and I always figured it was the residual fruit at the base.
Oh yeah, the squirrels---they are my problem!
I did not know that, and my grandparents had one in their yard.
I don't have a black walnut tree in my yard or neighbors yard but squirrels are constantly bringing the black walnut seeds/ shells
We have one huge walnut in the back where my garden is, and the garden does fine, so it must be far enough away. I only learned about the effect of juglone on surrounding plants this year. There are plenty of black walnuts on another part of my property that I can gather for medicine and food.
I heard rumors about it, but since I had none around, I didn't look any more into it. It is good to know because I love walnuts LOL
And now I know I can't plant it near anything that I'm going to grow basically just to be on the safe side. I prefer English Walnuts though.
I have 8 of those trees. I have 2 ft high raised beds. My problem is the squirrels are trying to plant a forest. I pulled seedlings out of my Greenstalks this year.
I need to check how far my black walnut trees are from my garden!
Hey Luke,I was aware but you maybe you weren't aware that squirrels could be the culprit for distributing the walnuts throughout the garden !
@davidlepoivre9519 squirrels carry the walnuts throughout my yard. I have found them in my front garden but it hasn't been a problem so far
That's interesting. I have a Hickory tree in my front yard. Do those have the same problem?
We have a couple black walnut trees near our orchard & they have caused issues to some of our fruit trees.
I was aware of the problem because I experienced it in my garden. Was unable to have stump removed and now it's growing suckers. How can I kill the stump and roots??
I drill holes in stumps and put salt ( water softener salt) in the holes. It takes time but works to kill the stumps 😊
I'm the earlier videos of roots and refuge they were starting small fires in the center of the stump of trees they cut down to remove it.
A big pile of hot compost over and around the stump
Hey brother my frost date is fast approaching. Y'all going to ship that garlic out any time soon? I love the videos and your products but that shipping time is sllllloooowwwwww
We are shipping every day. You will get your garlic in time :) We haven't even planted yet to ease your worries. It's too warm yet.
I was aware but didn't realize how fast the residue wore off. I grew up having to pick up walnuts from about 50 trees in my grandma's yard every day so she could mow and not have little shooting missiles 😅 to dodge
I
One question though, do the leaves contain the poison also? Thanks Luke for so much gardening information
I did know that walnut trees are not friendly to gardens, I absolutely love them though.
I knew the nuts were toxic to animals but didnt know about the roots. Explains why my tomatos and squash have done terribly since we moved. Would planting in fabric pots help?
Wow I didn't know that. Didn't even know there is such a thing as black walnut. Haha thanks for the educational lesson.
I learned something brand new here.
