Comments (9)The first defoliation was most likely a function of the change in light between where it was sited at school and the lower light area where it is/was at home. It's very possible that the crispy leaf tips/margins are being caused by over-watering, a high level of salts in the soil (from fertilizer and dissolved solids in your tap water), or a combination of both. If your plant is wilting when you can still detect moisture in the soil, it's almost certain that root function is impaired, and the plant 'perking up' as evening approaches supports that thought. Again, this may be the result of an overly water-retentive soil and the lack of air in the root zone that comes with it, or a high level of dissolved solids (salts) in the soil, or both. Even the recurring insect infestation can be resultant of a suppressed metabolism due to poor root health. The fix when your plant wilts while the soil is still moist is less water, not more, and a flushing of the soil to remove excess salts that may be inhibiting water uptake. A high level of salts in the soil can do the same thing to plants that salt does to cured meats, like ham, bacon, summer sausage ..... When the level of salts in the soil is higher than the level of salts in plant or animal cells (meat), the salt actually pulls moisture from cells. When this condition is severe, a condition called plasmolysis can result as cells collapse and plasma is torn from cell walls. Commonly, we call it fertilizer burn. Al PS - it's much more important to shade the container than the foliage. A light colored cache pot filled with an absorbent material you can keep moist (between the 2 pots) or a pot-in-pot arrangement with the outside pot being white or a light color would probably go a long way toward keeping root temps out of the danger zone....See Moretips of new growth have leaves curling & cupped
Comments (9)The closest image I have found is of the Tomato Yellow Leaf Curl Virus (TYLCV), but the symtom on my plants is not yellow or even yellowish. The curl that I see is not on mature leaves, only new growth and the immature leaves are very tight -- like, not opening or haven't yet opened) The curl might look like the TYLCV if the leaves were to mature and then turn yellow (with some imagination). Herbicide damage is out, non used on anything. Fluctuation in temperatures -- not remarkable. Over or under-watering is hard to imagine, since the garden soil is fairly loose and in raised gardens with more than a couple feet to the ground level. Before we water we put our hands in the soil to determine if watering is necessary. If anything, we might over-water to compensate for the airy/fast draining soil. Haven't seen any aphids around. Now that I've read about the virus that whitefly spread -- (TYLCV) we'll have to figure a way to keep them away. That will be another question. I hope Digdirt has the right idea. Maybe it is the "old non-harmful tomato leaf roll". That would have something to do with watering. The only thing we've added to the soil is a bloom-builder -- one time. These are plants that were started in early December and transplanted at about one foot high about a month ago. They have passed the stage when they should have been stacked or trellised -- just couldn't find the darn string! Hate to spend the gas, cause we have a big roll some darn place!...See MoreIn Ground Mango leaf tips are curling and bumpy
Comments (13)Well, you got the wrong side of the 74. I provided a link which shows my microclimate and zone and I choose the road map view so I can pinpoint exactly our zone. It says our minimum temp is 25-30, and that could be true, but only one day out of the entire year. It's mostly 30-35 min temp, and that is only 1-2 days. It snowed last year, but never stuck. We have the same climate as Temecula. In fact, wine country is creeping this way. Huge vineyard at the bottom of our hill. Fun to see all the little microclimates though! We are off Stetson in the hills on the East side of State. Our soil is decomposed granite. Drains well. If a tree can get it's roots under a boulder, it will be fine, and there are tons of boulders here both hidden underground and hugely visable above.

Comments (4)Some leaves on my tomatoes have curled and have a burn mark on them. Come to think of it one or two of my squash does also. My DH says I watered them to late and the water damaged the leafs? Could this be true? If not then what? **** Leaves can curl if it's too wet, too dry, too hot, too cold, if there's a heavy fruit burden and some varieties have leaves that curl normally, mostly hybrid varieties. So I ignore curled leaves unless and until other symptoms appear. How big are the plants right now? What color, shape and size are the burn marks you refer to and are they on all the tomatoes leaves or just some? And were the plants hardened off before being set out?
