Tomato leaves curling

My tomato plants were doing GREAT, but within the past few days the leaves have begun to curl inward - what is this? They are a beautiful healthy green, no signs of insects, plants are still growing

Quoted from Carolyn Male:
quote:
Basically Leaf Roll is a physiological problem while most causes of leaf curl are environmental.
I think I went over the leaf curl stuff in that same post but here it is again.
Leaves curl when it's too hot, too cool, too dry, too wet, too windy, or when the plant has a heavy fruit burden and most hybrids have leaves that curl normally.
If leaves curl over into a tube like structure, check for aphids.
So as I said above, I ignore leaf curl unless there are other symtoms.
Leaf curl can occur at any time while physiological Leaf Roll usually occurs early in the season when the plants are still immature, as I said previously.

Thanks, I'll relax a bit. We have had an extremly wet two weeks here on the Peninsula and I fear Blight. I'm growing plants in very large pots as I have done for the past four years - new soil each year. Good drainage. To prevent any possibility of Blight in advance, what can I do?

Julie, blight is mostly an airborne disease so fresh potting mix, clean containers and mulch will only go so far to help. The other thing you could do is start a preventative spraying regimen with a daconil based spray like Ortho's Garden disease control every 7-10 days. This will go a long way in preventing the most common fungal diseases.

Thanks John! ![[thumb]](im/graemlins/thumb.gif)
I was getting ready to start a topic about this when I noticed this one. Tonight I noticed that two of my six tomato plants were doing the same thing on the lower branches. ![[Frown]](im/frown.gif)
I was worried they had some kind of disease or pest problem. This explains it all and helps a lot. ![[kissies]](im/graemlins/kissies.gif)
Should I cut off those lower branches?![[dunno]](im/graemlins/dunno.gif)

Thanks Julie for starting this post.
I'm going to assume that the same is true for curled pepper leaves. Plants are healthy and buds are forming, just the leaves curling under.
My greenhouse is 90 degrees most days, I'm trying to cool it a bit by getting everything wet. I have quite a few plants in the greenhouse and they are thriving otherwise.

For this "New Year" help me to be kinder and more loving to all around me, I pray.

Do you have any fans or anything for air circulation? That might help. I'v never grown in a greenhouse but know air circulation is important. JD

After doing this though, i have one plant, that i took almost 1/3 of the plant away by just sappers alone. . has leaf curl almost the whole plant

The leaves arent brown. . nothing looks dead, but it was RIGHT after doing this. Think i may have shocked the plant? No other plant responded like this. . they are all looking fantastic!

I have a large fan going in my greenhouse at all times.
My plants are healthy, and I see no signs of little bugs, but I will keep watch.
