Why are leaves on Mandevilla turning yellow?

Blooming mandevillas need moist soil that drains well enough to prevent standing water. Too much water can choke the roots so they don't feed the plant adequately. This can cause the leaves to turn yellow. Conversely, too little water can be deadly, starting with yellow leaves that turn brown and drop off the plant.
