Managing Diseases in Hanging Baskets
Growers may often feel that the specter of contagious plant disease is hanging over their heads. This is never so true as when they are producing a crop in hanging baskets. It's not so much that disease management is any different for a hanging basket crop, but that the plants are much less accessible for monitoring or control treatments. An out-of-sight/out-of-mind philosophy is too often practiced with this crop. Special attention is required to produce a healthy crop above the grower's normal line of vision. This attention is important, though, because the health of hanging basket plants will affect the other plants in the greenhouse.
