Hostas prefer areas that are partly shaded or shaded. Some cultivars are sun-tolerant, but all do best if they receive shade in the afternoon.

Hostas prefer well-drained soil with plenty of organic matter. Hostas need plenty of moisture during the growing season to support the growth of their large, soft leaves. They will need an inch or more of water per week if not supplied by rains. If the weather is very hot or the plants are in sun or subject to root competition from trees and shrubs, they will need more water.

In early spring after the first growth starts, apply a well-balanced, slow-release fertilizer. Avoid excessive fertilizer rates.

Plant, transplant and divide hostas either in the early fall or in spring before leaves unfold. While hostas can be successfully divided at any time that they can be dug, they will need much more care if divided during summer heat. Divide hostas by either cutting away a section of a clump with its roots or by lifting the clump and separating it. Be sure to use clean, sharp tools. Replant the new plants promptly and water well. Space plants 1 to 3 feet apart, allowing room for growth. Hostas do best when left undisturbed for several years.

Remove flower stalks after bloom to encourage vigorous growth, rather than seed production. Remove hosta leaves and clean up around the plants after they have died back in the fall to help control diseases and slugs.
