Unfortunately they can't bear the winters here in the metroplex so they get wintered inside. This makes the leaves a little less tolarant to the heat they can experience in the hot summers.
I hadn't watered the lemon tree in about a week and the leaves started to curl. You can see some of the leaves have brown spots on them which happened when it got put back out for the first time this summer. The leaves curled more easily and the undersides burned in the sun.
Doing much better now.
