Hosta care should begin with the plant food that is available for good growth. There are several choices of fertilizer, including liquid; granular and slow release granular fertilizer. Follow the directions for application carefully to keep and promote healthy growth. Do not apply fertilizer over the top of new growth or on the leaves of the plant. Stop fertilizing in late July. Use a balanced fertilizer such as 10-10-10, and apply it in the early spring, followed by an application six weeks later, and finally a midsummer application. If you use a slow release fertilizer, apply early in the spring. Many gardens do not need additional fertilizer. Test the soil and add only the deficient nutrients.
You need to also consider water availability. Caring for hosta should include a minimum of 1 inch of water a week. The water demand can be met with rainfall, irrigation, or hand watering. Sandy soils increase the demand for water because of the faster water peculation qualities of sandy soils.
Finally, rely on observing conditions of inadequate water or holes in the plant leaves. This would indicate insect feeding. The leaf tips can show burning if the plant has inadequate water, also, drooping leaves can be an indicator of a water deficiency. Slugs, snails, and insects can cause leaf damage by chewing on the leaves as they feed. Check with a qualified source for chemical advice for control of these pests.

Dividing hostas is easily achieved. Most home gardeners will propagate their hostas by division. Hosta division should be done when no shoots are growing from the center of the mature clump as this bare area detracts from the appearance of the plant. Dividing hostas this way will improve the plants appearance.
Lift the entire hosta clump and wash the soil from the roots to make it easier to see where to cut and divide the clump. Use a sharp knife to make the cuts for dividing the hosta. Place the divided plants in their planting holes and keep them well watered for the first two weeks. Continue reading
The process for planting hostas is not much more different than any other plant. The planting hole should be dug at least a foot deep. The width of the hole should be one and a half times the expected mature size of the clump. Check with the nursery or web site where you purchased your hosta for the plants expected mature size.
Generally, hosta roots grow and spread horizontally, so a large wide hole is best. When planting hostas that are in a container, carefully remove the plant from the container. Sometimes the roots may be bound to the container. Tapping the container sides should loosen the roots from the pot. If the roots are difficult to loosen, it may be necessary to cut through some of them, make several vertical cuts in the routable. Shake the excess soil from the roots and do not use potting soil in the planting hole.
