A Gardeners Forum Forums General Discussion The Food Garden Forum The Tomato Forum Leaf curl again

I've done searches and it seems that the most common answer is not enough water. The leaves stay curled 24/7 no matter how much I water. I just thought I would post a picture to show what it looks like. I live in S. Oregon where it usually does not rain all summer or at least not enough to even get a plant wet let alone soak the ground. I usually water it twice a week with about 1 gallon each time.

Topthumb...leaf curl can indicate a disease problem, but it can also just be a matter of some varieties simply because they tend to do that. Those leaves look quite healthy to me, don't be too concerned yet, and by no means kill them with kindness, tomatoes like to dry out somewhat between waterings. It's actualy possible that you're overwatering, but, that's actually about right in most climates and soils.
To me, it actually appears that wind or the weight of rain has caused the plant to lean and the plant(s) have leaned einough to turn the underside of the leaves up, if that makes sense. Keep an eye on the plant and post more pics if you see problems develop, but don't fret just now.

Odd...I was talking to my wife's aunt about this very issue a couple hours ago. She's an expert gardener and frankly, I've never seen a perfectly placed and weeded garden like hers.

I was complaining that when I water my garden a few mornings a week (SE Michigan) the tomato plants tend to wilt. However, when it rains, they green right up and shoot upwards.

She said she has observed the same thing and said the plants probably don't like the chemicals used to treat the water. And there are trace residuals of medications in the treated water as well.

That may be voodoo logic but there's a noticable a difference between Mother Nature's water vs. city water.
