Hostas grow best in moist, well-drained, highly organic soils with a pH between 5.5 and 7.5. Sandy loam is better than clay because it provides more aeration for the roots. High-filtered or dappled sunlight is necessary for clean, healthy growth. Morning sun is tolerable and will help to intensify the leaf colors, but hot afternoon sun is usually deadly to hostas. They are most at home in shady, woodland settings. Be sure to clean all hosta foliage out of the garden in early winter after the plants have gone dormant. By doing so, you will be ridding the area of the eggs of slugs and other leaf-eating insects.
