- I love growing heirloom tomatoes. There are so many reasons why I love them. But along with all those positive things, there is one big negative. Many heirlooms aren't very resistant to many of the tomato diseases. One of those diseases is fusarium wilt. Although I've never really had a problem with it, my luck ran out this year, when one of my tomato plants showed the classic symptoms of the disease. I'll show how I handled the situation, and give my number 1 tip on how to avoid having to deal with it.

Great video. I just bought a tomato plant in May for the first time. I put it in a container with soil I bought from the garden store. It has this Fusarium wilt. Bummer, I really love the tomatoes. They are grafted Cherokee purple. It's got a lot of tomatoes on it right now, so I'll let those ripen and then throw it away. Any advice on how I could have avoided it? This was a plant and soil I purchased from the garden center. Not soil already in place in my garden. I have zero gardening experience.
This is something that I really haven't had a whole lot of experience with it, but it's my understanding that it usually comes from the soil. Of course, if you bought it as a plant, it could have came with the plant also, but if it is a grafted plant, then the yellowing might be caused by some other reason. If it's in a container, I wouldn't even throw the plant away. I would just let it grow. Since mine was in the ground, I didn't want any more soil to be contaminated. Sometimes if the soil is deficient in magnesium the leaves can yellow. If that is what is causing it, Try mixing about a table spoon of epsom salt with a gallon of water and spray it on the leaves, and see if that helps the yellowing. Also, do the stems look good and solid and healthy? If so, it's probably not fusarium wilt. The reason I don't think you have it is because normally a grafted plant would be resistant to it. That is the whole purpose of grafting......to improve disease resistance and improve vigor.
Sorry to be so long winded, but I hope this helps a little. And I forgot to mention that it is pretty neat that you have grafted plants available. Those are pretty hard to find around here.
Just thought of a couple of more things I should have mentioned. Too much or not enough water, and not enough nitrogen can also cause tomato leaves to turn yellow. I know this is a lot to think about, but since you said you had zero experience, I thought I should be thorough.
I'm glad to hear you think it doesn't have it! I've tried to water it carefully, but the leaves have almost all turned brown and fallen off on one side. I'll take a video and post it to UA-cam and share the link with you. In either case, I sure done have anything to lose by keeping it in the pot and not throwing it away. And I really like the tomatoes! I'll try the epsome salt spray
Thanks!
Title: “Fusarium Wilt on Tomatoes and How I Handled It”.... throws it in the trash 😂
Exactly right.
Sorry to hear about your Fusarium Wilt woes. Hope things are better for you these days. Happy gardening sir.
Thanks! Everything is going great now. Happy gardening to you too!
I'm sorry to see you loosing a plant Jim. I agree, I clean up everything after use just to be safe. Hopefully this is the only casualty until the end of the season.
Thanks! I hope so too. You just never know with heirlooms though.
Midwest Gardener I agree, as tasty as they are, they sure are risky too.
Yep, but I just can't make myself stop growing them :)
Fantastic advice and information on Fusarium wilt and what to do !! Thanks for sharing
Thanks for watching! Much appreciated.
Hi Jim, another low that you had to encounter this growing season (F.W) sad to see you lose a loaded tomato plant :((but at the same time its better to nip it in the bud than let it spread around & thanks for the tip and thanks for sharing this video.
Thanks Sue! It's just one of those things that we gardeners have to deal with some times. I just hope I don't see it again for a while.
140*F will kill it. Cover with a black plastic bed. Plant a trial next season. Blessings on you efforts I pray.
Thanks a bunch for the tip!
One reason I moved to 15g Fabric Pots. I have a Virginia Sweets that looks suspect. Some branch arms with the clear yellow only on one side... I have fine straw thick on top and water carefully. I'll be dragging it out of the area and putting it on its own for a bit. HOPEFULLY I can use that pot for Peppers next year. I've not looked that up.
Tomatoes really are difficult. Virginia Sweets usually performs well for me. Luck of the draw.
I agree. Tomatoes can be difficult. They would be so much more fun if it wasn't for diseases. Good luck!
Great video! Have a wonderful new week Mr. Jim!
Thanks Catalin! You have a great week too.
Thanks for the information Jim. l had not heard of it before. Best wishes Bob.
I hope you never have to deal with it, Bob. It's hard to get rid of from what I've read.
Watch what you add to your soil too. Uncured and unsterilized manures and composts will create major problems. I had issues with compost this year.
Thanks for sharing that. Persistent herbicides in compost manure, and hay can be a real problem. I've been thinking about doing a video on the subject.
I still have to wonder if something can't be poured into the soil. IDK - Vinegar? Just to try to use the spot. IDK.
I don't think vinegar would help, but I don't know of anything else either. I've never heard of anything anyway.
That sucks, but you did right. Don't let it spread.
Yep, I sure hope it doesn't spread. That would really suck.
It’s in the soil. It will spread, how far I don’t know , but you can’t get rid of it to my knowledge. It’s depressing, but I may try the clear plastic next year, and try grow bags on top of it.
What a small world... my tomato plants are having some serious problems and it seems to be fusarium... I searched the web and decided to look for a video... yours was the first to pop up 😊 Do you think I have to replace the soil in my raised garden bed?
Oh wow, I sure hope not. That would be a major pain. Is your plant mainly yellow on one side, or is it yellow across the whole plant? It could be some other things too, so I wouldn't change the soil yet.
😩😩😩😩😩
so glad you showed this. I would have thought it was normal coloring of the leaves due to it being a little late in the season. you throwing the tomatoes away floored me.
Living in the soil for all those years. wow.
I think Mother Nature has claimed you and made you the expert :-) Thanks for the information.👍
I think she made me something of hers, but not an expert :) She has slapped me around pretty good this year. I hope that means she will take it easy on my next year.
Midwest Gardener I hope so. This has been very stressful for me and It's not even MY garden lol.
So sorry to see that happen. I would pour vinegar in the soil. And let it rest like you are doing.
Thanks for the tip. That's just the way it goes.
Great scientific video! Too bad you couldn't save those beautiful yellow tomatoes😣
Thanks!
Hey Jim, sorry about you tomato plant, but the line where you say you read until your eyes started to roll back in your head made me LOL. I guess I'm always into denial, because I will cut the leaves off until all the tomatoes have ripen... but I always throw the plants in the trash and clean my tools I used to work with them. Disinfecting everything is a great plan. T
I agree about the disinfecting. Always good to be cautious. And throwing the plants in the trash is a good idea in my opinion too.
You should try grafting some tomatoes next year!
I tried for the first time this year, without a whole lot of success. But next year, I think I will do a few more grafts than this year. I have some interesting experiments that I haven't shared yet. Not sure if it will work, so I'm keeping an eye on them.
I know you grafted onto mature plants, but I think you should try grafting with small seedlings, you might have greater success.
Yes, I grafted seedlings this spring, and didn't do a very good job of it. I plan to try again next year with what I've learned. I still have one surviving grafted plant that was grafted as a seedling. It is the carbon grafted onto maxifort rootstock. It's the same plant that I'm doing additional grafts to now.
I have a sun gold plant which has some branches wilting, but most are not. The leaves are still dark green but I am afraid that the plant has some sort of bacterial wilt. It is a caged plant that I didn't prune so if I yank it out of the garden it will leave a fairly big open space, but I think I need to just eliminate the plant to prevent spreading to my other tomato plants. Would you suggest doing this, or just cut off the wilty branches..? Good video.
Hey Lucas. I sure hate to hear about your plant. That's always disappointing. On some things that are slow moving, I cut off the diseased looking leaves and see how it goes. If it is something that is moving pretty fast, and really hitting the plant hard, I often just pull the plant so it won't spread. That is how I handle mine. Other have other ways of doing things. I just don't like to risk all my plants to try to save one...or two.
I forgot to mention that I always disinfect my pruners between plants.
Ok, thanks for the help! I think I'll cut off some branches and monitor the plant.
Sanitation is key!
You're welcome. Good luck!
I’m feeling pretty defeated cause I have it.. thank u for this video
You're welcome, but sorry to hear it.
It had yellow leaves, but nothing in the video showed any wilting. The pant looked entirely turgid.
It's too late now, so hopefully I didn't make a mistake.
Your garden is so beautiful. Hope you stopped it from spreading.
Thanks Sue! I sure hope so too.
My tomato plant is wilting and the top leaves are losing their color; not turning really yellow but white. The lower leaves are still a dark green color. Is that fusarium wilt or is it something else?
It sounds like something else, but there are so many diseased that effect tomatoes, that it is hard to say what.
What about cleaning your tools with alcohol in a spray bottle and wiping clean?
I would have sprayed the soil as well it should be safe for the environment.
People use bleach sprays to clean the outsides of houses who have siding. Within a parameter it should kill diseases too.
I thought my neighbor killed my Pecan trees but infact I had a problem with them not producing and this year they are doing super.
I do not see doing around about stuff on this level unless you are trying to teach people correctly.
I watch gardening stuff like sporting events here lately to see what might happen and problems one could face in the garden.
I'm just like pour a little bleach on it and plant next year anyway.
Where is DDT when we need it?
Thanks for sharing your thoughts!
Had you already tried adding magnesium for your plant? I think there's some talk that yellow leaves can indicate a deficiency of that mineral.
No, I didn't try that, but it is a good thought. I did think of it maybe being deficient in something, but I just didn't need tomatoes enough to take a chance.
I use a propane torch to sterilize the cages
Thanks for the tip!
Keep it up 😀
Thanks.
Solarize the garden area! Unless its sterilized, the Fusarium fungus can lie dormant and persist for 20 years.
Thanks for the tip. Wow, that's a long time!
You can solarize that area with clear plastic over the summer, it should be ready for a fall crop. 130 degrees F for 3 weeks is what the commercial soil suppliers like Kelloggs use to sterilize their soils before shipping to home depot for sale to the public.
Thanks for the additional information! Much appreciated!
you could still eat the tomato. id have picked them off and set them in the kitchen to ripe up. they were almost there. It doesn't spread to people and the fruit from what I heard is sweeter due to the lack of water. not encouraging to keep the plant but just sayin
Thanks for the information. Much appreciated!
I wish I had enough knowledge and money so that I can genetically modify heirloom tomatoes to be resistant to the fusarium wilt but sadly even if I could someone probably patented those genetic sequences and would sue me if I would share my improved varieties.
I know what you mean....that would be nice. There's always a catch.
Yeah, my theory is if it isn't helping the plant, take it off.
Yep, that's a good place to start.
Are you sure that’s not tobacco mosaic virus? I got this last year and thought it was tobacco mosaic virus
I'm not 100% sure that it's Fusarium wilt, but most of the photos I've seen of tobacco mosaic virus look more blotchy than this plant looked. Also it seemed to affect one side of the plant, which is what happens with Fusarium Wilt sometimes.
wise decision to trash can the plant, better safe than sorry!!
Thanks Mick. Yep, that is what I was thinking too.
You had to dissect the stem to be sure it was fusarium.
Thanks for the information Robert. Yeah, I don't remember everything I said in this video, but I wasn't 100% sure that it was Fusarium. I really didn't need the tomatoes bad enough to take a chance on leaving it in my garden. I'm kind of like that. If it's diseased, or I suspect it is, I usually pull it out.
Fusarium usually starts to activate in the plant when the plant starts to flower. Wilt + odd sporadic yellowing of entire branches usually = bad news lol.
