Q: I know the best time to plant trees and shrubs is mid-fall. But when is the best time to plant ornamental grasses?
A: In contrast to woody plants and perennial flowers, ornamental grasses do best when planted in spring and early summer. For best results, untangle the roots as best you can, spread them wide and soak the soil thoroughly after planting. Feed grasses once each year after vigorous new growth has appeared. Overfeeding will result in floppy stems.
