Tomato Leaf Roll/Curl

14 years ago

Okay, so for the last two weeks, my tomato plants (marglobes) have had rolling leaves. We've had a lot of rain lately. I didn't think it was too much but I guess so. They aren't yellowing or spotted or anything so I wasn't really worried at first. But now it seems like the upper half of the plants are suffering too. Here are some pictures:

This is the bottom 3/4 of the plant

The lower leaves have nearly straight edges. The upper leaves, as shown here are very jagged. I'm not sure if that's normal. But what worries me is how they're curling up at the edges. The texture and veins look weird too.

As far as I can tell, drainage is pretty good. Water doesn't pool or anything, but I can't say about ground level inside the raised bed. I think it drains okay. Is there something I can do or should do? Should I be worried?

    Some heavy leaf rolling on the top pic, and lots of leaves on wet ground. Leaf rolling can be caused by any stress, and those touching the ground will likely get infected.

    Cut off anything touching the ground and if you can, mulch heavily.

    Okay, I'll try that. Thanks. And....*drum roll*....it's raining again. Hopefully we'll get some good sunny weather after this.

    Have you check closely for aphids? Severe rolling such as that is often caused by aphids.

    I'd also be curious as to the feeding they have had. All that rain will dilute and leach off much of the available nutrients, especially micro-nutrients, so feeding them may help.

    As to mulch, while I am a big advocate of it normally, keep in mind that mulched soil takes much longer to dry out and right now wet soil is your primary problem.

    Have you used manure on your tomato beds at all? I am having the same issues and it is from manure that has been tainted with aminopyralid(herbicide). Apparently farmers use it to suppress thistle and other weeds in the fields and it does not affect them when they eat it, nor does it break down. Anyway, jean001a, a form member recommended I read the following web page:

    I really hope this is not what you have, but it seems that this issue is pretty common amongst gardeners who use manure.

    I just read (somewhere) that this happens often when one prunes to one vine...which I do and this happens to me it seems always. It never seems to effect production, but veryu unsightly and worrisome. I wish I knew for certain.

    confirming my case of leaf curl, my landscaper sprayed weed killer in the lawn and sure enough in few days I get leaf curl, some plants got it pretty bad. I am sure it will grow out of it. Last year I got leaf curl but that did not affect production.

    I think everyone here has hit the nail on the head. That was my instinct as well, but I wanted to get a second opinion. Fran35, no I haven't used manure at all in my garden. However I do suspect herbicide damage. I've been checking for whiteflies, aphids, etc but I've had a lot of spiders (that I have to try VERY hard to leave alone lol!) and I haven't seen any so I don't think that's the problem. So I pruned up the bottoms a bit (didn't want to do too much and stress them out more) so they're not hanging down in the soil now. I skipped the mulching for now. I'll save that probably for next month. Until we get well into summer, we usually get a fair amount of rain. I spread some organic tomato fertilizer today and I'll have to water it in tomorrow morning. Hopefully that will help. I just read something about too much nitrogen causing leaf roll but hopefully that's not the case here. With all the rain, I highly doubt it. The thing I suspect that has had the greatest effect on at least the upper leaves might be herbicide damage. Everyone around here has been spraying their yards regularly. I googled herbicide damage and the images look just like what I've got here. The good news is, it's not dying back so they should be just fine. I just hope it doesn't get any worse. I know it must be normal for a little bit of foliage to die off, especially around the bottom where it gets old. Plus I would think it needs to get rid of some to put more energy into the top growth. But it still makes me nervous, being a new gardener and all. Am I right about that? It's my first garden so if I mess something up and lose all my tomatoes, I'm going to be so discouraged. But I know that's how we learn. I'd just rather learn from others and not my own mistakes. lol!

    So last week we had a bad thunderstorm move through. Wind gusts up to 80mph. Yikes! I've lived in Oklahoma my whole life and I don't think I've ever witnessed wind like that before. It blew our brand new grill out into the yard and banged it up. Sad face :( Anyway, I covered my pepper plants with large clay pots since they're still short enough. They did just fine thankfully. My squash plant was even small enough still to sort of be stuffed into a 3 gallon pot. It probably wasn't too comfy in there, but it didn't get any damage! It's HUGE now so I hope our severe weather is over for the season. The tomatoes had some branches that got blown around so hard that they sort of went limp. Only one small branch actually broke off so I spent an hour or so the next day strapping up the weakened ones. All is well now. Anyway, I brought in my potted plants, including a Better Bush tomato. It's working on it's second fruit set and flowering like crazy. In the last few weeks, since harvesting the first of the fruit near the bottom, the leaves at the bottom of the plant have died back. I left the pot indoors for a couple of days because the weather was still a little nuts. I don't think it liked that at all. The leaves and stems are turning yellow from the bottom up. Even the leaves around the current fruit set. I am not sure what's going on there but I did ad some home made compost to the pot a couple weeks ago. Maybe it's off balance now? I added the same compost to my peppers and squash and they are all doing great, minus a pepper blossom turning yellow and dropping here and there. Just one or two, I'm sure that's normal. They're still producing and the foliage looks fine. I put just a sprinkle of tomato fertilizer in the pot and I'll water that in tomorrow morning as well.

    One last thought for the night. When I sprinkled the fertilizer around the tomatoes in the garden earlier, I noticed within minutes, ants all over the surface carrying away bits of the fertilizer. Anyone else ever seen that? Should that concern me? I just kinda thought it was neat.

    If you gonna eat those ants, wash them first :P

    Otherwise, just keep leaves off the ground either by mulching heavily or pruning anything a foot off the ground, preferably both. And dont over love/babysit them.

    I have a friend who owns a waterfront summer house, who planted my seedlings both there and at regular house last year... ones he didnt have time for grew the best tomatoes.

    Granted he was watering his primary house ones daily, eventhough I told him not too.

    Point is, sometimes the best cure is to let em do what they do :P
