Then feed them every 2 weeks with a water-soluble fertilizer while the growing season lasts. Stop this schedule when there’s about a month left till winter to help them harden.
Care & tips
Hostas, once established, require very little to no maintenance. It does not need special care in most regions in winter. One thing you should do is remove any dead foliage, as it can result in a pest infestation during winter.

Deer find this plant irresistible so put it behind a fence if your area has such a problem. Slugs and snails are also common problems that plague hostas. Simply clean the debris from the ground around the plants to discourage these pests.
Shriveled and brown leaf edges are indications that the plant has received too much sun. Hail can seriously damage hostas leading to infections. If you see spots on the leaves, then it may be a bacterial problem. Use soaker hoses to water the plant to treat this.
If you see the hostas’ growth is stunted and the foliage turning yellow, then too much watering, and subsequently, crown rot may be the problem.
Propagating is very simple and easy for hostas. During early spring or fall, dig up the plant, and break up the root clump. Ideally, every clump should have some leaves but it’s not a problem if it does not. Then plant them where you want.
