Hostas are hardy perennial plants that are frost tolerant to zone 3. All hostas require at least several weeks of winter chilling to below 4 degrees C. as part of their annual cycle of growth and rest. Hostas can be quite drought tolerant but when they are under stress their leaves will turn brown and burn.
Understanding the needs of hostas, and providing these needs will determine how well your hostas will grow. Hostas need well drained fertile soil, a bit of protection from the hot afternoon sun and an adequate water supply. However their needs may vary greatly in their individual requirements such as those for miniature hostas vs large hostas, or for late flowering hostas.
Hostas look best when planted with ferns or other perennials. When planting in the woods with wildflowers, make sure you remove all the surface tree roots within 2 feet of each hosta clump.
