Question: I am having trouble keeping my Lisianthus plants healthy until it's time to plant them outside on June 1. They keep wilting. Any suggestions? I have about 6 of them and they look terrible. Peggy Paterra Sharon, MA
Answer: The roots of Lisianthus are very sensitive. Too much water and they die...thus the wilting. If you knock one out of its pot, you will probably see brown roots. When planting, mix in perlite to increase drainage and oxygen content. Be sure to put a layer of perlite on the surface of the soil to keep the foliage dry.
