Planting Bare Root Perennials  Most perennials aren’t picky
about planting times. They can be planted in the fall or the
spring, as long as they are not in a period of active growth.
Generally, it’s best to plant spring-flowering perennials in the
fall, and late summer to fall bloomers in the spring. You may
find the best selection for variety and quality at the nursery
in the late summer or early fall. Save these in sheltered area
and keep them watered until the weather cools.  Perennials are
generally sold in pots or bare-root. Here are the steps to
follow when planting a bare root perennial:    1. Remove the
plant from its package, and carefully remove all loose packing
material (peat moss and sawdust are commonly used).   2. Soak
the roots in a bucket of water for 5 to 10 minutes.   3. Examine
the root system, and trim away any rotted, moldy, broken or
elongated roots with a sharp knife of your pruning shears.   4.
Dig a hole deep and wide enough to allow the roots to fan out
from the crown at about 450 a
