The leaves on two tomatoes plants in my greenhouse have started to curl and the tops of the plants are curled up and look distorted. They both have flower trusses, but look like they have now stopped growing. Any ideas what this might be?

Can you take a piccie and post it up here?

Some leaf distortion can occur naturally and might not be anything to worry about.

Can I just check whether you've put any manure on the tomatoes at any point?

Are these the only tomatoes you've got growing in the greenhouse?  Are they the only ones of this particular variety?  have you done anything different with them from any other tomatoes?

Not put any weed killer on the lawn?

I've fallen foul of this in the past.

Thanks for the quick replys.  Both tomatoe plants are in growbags, two different varieties in seprate growbags. I did put wilted comfrey leaves at the base of all  the plants, (read this in a gardening book) All the other plants are fine, wondering if I should just whip out these two.

Tonight I noticed mine were curling too! Methinks it is the heat.......

Have you checked for aphids ?

[viettaclark]

As the curling only started tonight and ALL the plants have it I don't think it's aphids....
It has been VERY hot from being VERY cold......I'd probably curl up too.....

Leaf curl in a young plant is very often nothing to worry about.  Just keep an eye out. (unless that's too painful).
