So I have 12 tomato plants and one in particular is presenting leaf curl. I noticed it the other day and it's gotten progressively worse. I was thinking it may have something to do with water since I'm still playing with water duration on mydrip irrigation and what not. But all the others are fine. I'll take a picture and post it. Thanks.
I have some that do that every year. It does not affect the tomatoes just a weird leaf curl. Usually it affects the hybrids more than the heirlooms !! I just ignore it !!
It could simply be caused by hot and dry weather. The leaves roll or curl in an attempt to protect itsself. You may be able to fix this with watering or spraying. When iyt occurs here, I do like Mart and just ignore it. Obviously there are other causes such as viruses, fungi, incorrect irrigation, mites or herbicide residues. Yours looks innocent to me at this stage.
Well things have been far from hot and dry here in SE Wisconsin. We had rain almost every day last week and we had a storm the other day that I forgot to delay my irrigation timer. So it watered during a rain storm. I did read though that it could be either of the extremes from to dry to to wet. We have some better days coming up with warmer weather and less rain.
You are right,, can be either too much all at once or too little or a mix of the two. My tomatoes have just as good production with the curl so I just do not worry about it.
