Hostas grow best in shady or partially shady locations. They prefer a rich, slightly moist soil so keep them mulched for consistent soil moisture. Hosta is relatively drought tolerant, but it's still a good idea not to let them dry out too much. Dig and divide the plants every three to five years in the early spring just as the plants are putting out new growth. Slugs, snails, deer, and rabbits like hosta almost as people do so use appropriate measures to keep these unwelcome guests at bay.
