Mandevilla Plant


chofer added on January 24, 2017 | Answered

I have moved it indoors and am seeing clumps of white at the base of leaves and on the stems. What is it, and what should I spray or do? Should I cut back, as plant is losing most of its leaves?

As for the lost leaves, just make sure not to overwater the plants, since they'll use less water.
