Tomato disease - leaves curl and whither, yellow and brown spots
Comments (3)Leaf curling alone is a physiological condition caused by stress; it's common in stressed plants, including young plants which don't have the root system to support all their foliage yet, or in times of unusually bright sunlight. If you get it by itself, look to see what may have stressed the plant recently; often it's nothing to worry about. The wilting, dead green leaves symptom resembles bacterial wilt, but that's pretty rare in your neck of the woods, and tends to take the whole plant down very rapidly. Stem borers can sometimes do it; look for little holes in the affected stems. Look for any damage to the stem, in fact. With the yellowing and necrosis -- it's hard to see in that small a photo, but it looks like the dark lesions are following the veins. That's diagnostic of a toxin of some kind -- no virus I know of does that in tomato, no bacterium or fungus is that specific, and no deficiency kills the veins before the interveinal spaces. I've seen a symptom almost identical to that in a case of alcohol poisoning (someone had a cocktail party in a library foyer and apparently the drinks weren't very good, as the potted plants looked pretty rough afterward). It was an unusual enough symptom that it became a teaching example. Toxins can come from outside or from the soil. Pyola is perfectly safe for tomatoes, and the heat wasn't excessive, but make sure the dilution was correct, as too high a concentration can burn leaves much like that. Spray damage can also cause wilted and dead green leaves. If you can sacrifice a plant that's badly affected, dig it up to look at the roots, see whether it has lots of crisp, white, fine roots, not dark or knobby ones. Shave away the skin at the soil line to look for discolorations in the woody stem underneath; cut open wilted green shoots to check for hollow centers from stem borers; and finally split open the main stem to see whether it's hollow or discolored inside. I don't expect much except maybe root symptoms, but you really never know. My personal guess is soil toxicity, especially given that the lower and terminal leaves are the worst affected by the yellowing and dying, and some things take a while to build up in the leaves enough to kill them. One important thing to note is that not all toxins are synthetic chemicals -- an excess of certain minerals or nutrients can poison a plant. pH affects root uptake of anything enormously, especially minerals, but it can have its own effect as well. You may need a soil test -- call your Agriculture Department, Cooperative Extension, or U of O to find an affordable lab. I don't see your symptoms in any of the common nutrient toxicity listings, though, which means it could be something chemical, and there is no general panel for that. Down here in California I'd send it to Sacramento's Plant Diagnostics lab or the extension pathologist at U. C. Davis, but I don't know what pathologists you have at your disposal. This is certainly not a cut-and-dried common disease problem, and even a specialist is going to need some lab work to figure it out, I suspect. I wish I had more answers for you, sorry. --Alison...See MoreTomato leaves curling/wilting with some tan/brown spots
Comments (8)Dang. Heartbreaking to see your pictures. Hope you can nurse them back. I was thinking overspray too, but I have a similar problem with leaf curl but no drying. I believe I used too much compost. The man at the nursery suggested too much water; we have had a lot of rain lately. Also, he said to cultivate around the plants to release any gasses that may be trapped in the soil. I'll try anything, but it's too soon to tell. Wish I had more info for you....See MoreNeed help with Tomato - Brown Spots, Curled Leaves, Indoor Garden
Comments (5)Dan, I've used a few different mixes in containers and I like the sound of your sea soil. The problem with containers is that the system is really too small to set up a true organic soil system in them. People do all sorts of things and may technically get away with it, but I my abilities can't do a completely organic soil and get reliable production, since any "help" and you kid yourself that it is "almost organic". That said, I had some luck with a mixture of 1/3 compost (Black Kow Composted Organic), 1/3 peat & 1/3 perlite in summer but you must watch it doesn't get waterlogged. I know it sounds strange, but raw perlite is "organic". You could put some of those fancy rock dusts in there and dolomitic lime and give it a whirl. Problem is at some point your plants will need the nutrient boost of something like Miracle Gro, which is not organic, but not as bad as some make it out to be, either! There are some Fox Farms hydroponic/organic and Dutch Master hydro organic ones, but these things are really cost intensive and there is no way I could afford to even evaluate them. Tomato-Tone is organic and you can use some of it (the affordable option I would use) but a lot of experimentation is necessary to get it right in a bucket. Those are the tools I would use. There are others that are more expert than I am in this forum on organic methods in a container, but the problem is that ingredients and climates can vary enough that a lot of experimentation is necessary anyway and it is a bit much to ask of a container considering the nutrient demands of a big tomato plant. And a bigger contaner ( say, 25 gallons) can be costly to fill with organic nutrients only. There are other much more economic ways to go if you drop the requirement of deriving all nutrition from "organic" sources, for example pine mulch, etc, is cheap but offers no nutrition so it doesn't get you anywhere nutrient wise, though it might help you save on perlite. I can't answer whether your tap is appropriate for your plant, even knowing the pH is 7.5. That's because it will be the interaction among the tap, soil ingredients and amendments that determine the pH of the container. For example, if your soil starts on the acid side which it likely will it needs to be neutralized with some lime, but you can do what I do ... put less in and water with alkaline water for a while. Clearly that is not an optimal situation but to be honest my plants do fine despite all the issues with pH, and my tap is pH 7.7. But this is a fragil relationship and the only way to now for sure is to pH test your soil while you grow toget the hang of what's happening, if you are really enthusiastic. Just because it works for me, btw, doesn't mean it will work for everyone. We get lots of rain here and that frequently washes trhough soil mixesand I purposely open the tops wide to encourage that. No residue builds up from the tap or any of my not-organic supplements due to the rain. The common wisdom of hydroponics of a vegetative and a reproductive period fertilization schemes doesn't seem very pronounced to me when growing the tomato for the long haul. To be perfectly honest, I think all these mantras about vegetative stages and drastic changes during flowering stages are geared towards high value crops LOL. Really with tomato plants you want to keep the nitrogen at a baseline, low in all of my scenarios. You are not growing vines, they get quickly unmanageable for indeterminates and make few tomatoes, and most everyone here seems to agree that being pretty stingy with nitrogen is the way to go. That's the opposite of what you've done. When I grow my tomatoes, my seedlings have only 1/2 to 2/3 the nitrogen the producing plants do, so my nitrogen rate actually increases for me. At the end I back off though because the plants get less productive and unmanageable so there's a lot of give and take. Hope that helps a little, because nothing is as easy as it seems, so most people find something that works and get pretty stuck to it.

Comments (1)Black bottoms is blossom end rot (BER) -- due to uneven soil moisture which, in turn, means that insufficient calcium is transported to the cells and then they die. Radial cracking is "normal" with some kinds of tomatoes but is made worse by erratic moisture levels. The spotted leaves may be a disease -- Perhaps your County's Extension Service office could help you with that. Find that office here -- http://npic.orst.edu/pest/countyext.htm...See Moresg495
