A large, full-bodied hosta--or a cluster of them--can fill in shaded areas of your garden, line shady walkways or provide a base to your shade trees. Coming in many colors, leaf sizes and variations, a hosta is a steady growing plant that is easy to grow and maintain. Take quick action as soon as you notice damage from pests or disease to keep your hostas thriving.
Clear away any damaged leaves by gently tugging away the yellow or brown leaves or clipping them off as close to the base as possible.
Place any removed leaves in a garbage bag to dispose of them. Only put discarded leaves in a compost bin if you are certain your damage is from insects or other animals and not from disease, fungus or bacteria.
Apply any fungicide or insecticide to the remainder of the plant as needed following the dosage and application method given on the label.
Monitor your hosta as it recovers from the damage. Water your plant if your area is receiving little rain.
Dig up severely damaged hostas and plant them in a pot or container to isolate them from the rest of the garden. Nurse the plants back to health through watering, fertilizer and mulch when needed.
