Good morning.

This is a perplexing problem and I am not sure what the issue is.  Any advice would be appreciated.

I started  my tomatoes from seed this year.   I have a few plants that I purchased just as a backup, but 90% of my plants are ones I started from seed.

All of the ones I started from seed are curling in the leaves, as is pictured.  They do not seem to be putting on any new  growth. All of the plants I bought are  doing great.  Dark green, healthy,and growing.

I water at 6am every morning, before the heat sets in for the day.

Any thoughts as to what could be causing this?

Thank you.

At first, I thought they looked more deformed than curled. I have plants in both a raised garden and a few in containers planted in potting soil so that eliminated the soil as the problem. Since everyone of these plants seems to be developing right on schedule, I've quit worring about it. I've poured through every gardening book at my disposal and found nothing that could apply to my plants. At least I know I'm not the only one!

Maryserv writes: I wanted to add this as I've experienced the same thing. There are several things that will come up when you search under "physiologic leaf curl". The way I determined it is only a water stress situation and not a virus or other problem is that I closely monitored the water level of the soil. New leaf growth with the right level of watering will look better and the curled, stunted leaves will unroll a bit. They will not ever look the way a "regular" leaf looks, but it does not hurt the production.

One of the things that came up was a copper deficiency. If the soil was well prepared prior to planting, there should be enough copper, BUT they has to be enough water to make that copper soluble for the plant. I increased my watering a smidge and then feed them lightly with a macro and micro nutrients. Good luck!

When I discussed it with county agent he felt I had accidentally let some weed killer I had used on the yard a little away from the tomatoes drift onto this plant. Mine, too is holding beautiful fruit, but looks curled.

BloominChick writes: I have a few of thoughts: Could be you need to water more frequently, say 2x a day, (especially if this is in full sun and your temps are hot) or the roots could be bound (preventing water & nutrients from getting into the plant causing the leaves to curl) or it's tomato blight/contamination (the seeds could be from those which are prone to the blight right now or something in the soil has contaminated the plant - have you fertilized recently? If so, with what?) Some curling is normal depending on the variety though this does seem excessive. Try watering twice a day, if that doesn't help, perhaps dig it up, make sure its' roots are all bound together and transfer to a large container with fresh soil. If none of that works, perhaps your local agricultural extension or master gardeners could give you help with a diagnosis.

alethor writes: I have the same problem in one of my tomatoes: Black Krim.
It is very tall right now, I keep removing the suckers because it is an indeterminate variety. I do have about 10 tomatoes ... not ready yet !
The leaves are dark green and they are curling too.
Help ... anybody !!
