Q.Why Are the New Leaves on My Tomatoes Curling and Hard?
The new leaves on all my tomatoes are curled up and almost leathery to the touch. After they get more age, they look normal. The little fruit I have now doesn’t seem to be affected, as of yet anyway. What can we do aside from destorying the plants? There are four, what, if anything, can be done in the future to prevent this from happening again?
