How do trees respond to drought conditions?
When there isn’t enough water in the soil for a tree to take up, the tree will close the pores in its leaves that respire oxygen and residual water (this process is called transpiration) until temperatures are cooler or moisture is available. If the moisture level remains too low for extended periods of time, the tree will use up stored water and the leaves will begin to wilt. If dry conditions continue the tree may drop leaves early or die back. Sometimes trees produce excessive fruit in an effort to help the species survive. If a tree is deciduous it may go deciduous early or develop leaves later than normal.

If you notice these conditions occurring in your tree, check the soil moisture to see if there is enough to support water uptake. Refer to the question above, "How can I tell if my tree is getting enough water?" for information on checking soil moisture.
