Horticultural Tips
November Tips
q Plant container-grown, B&B, and bare-root trees and shrubs when the ground is not frozen. Always plant at the same level plants were grown at the nursery, or slightly higher. Top-dress with 2" of compost.
q Thoroughly water and mulch new plantings, keeping mulch away from the plant's trunk.
q Add new mulch to existing beds if needed.
q Consider composting fallen leaves rather than placing them at curb-side. Or, run the lawn mower over a low pile and watch them disappear!
q Prune broadleaf and narrowleaf evergreen shrubs to shape. Do not prune spring flowering shrubs or vines.
q Continue to inspect evergreen shrubs for scale (particularly Euonymus, boxwood and Burford Holly). Spray with insecticide now or with dormant oil in late winter. Heavy infestations can kill plants.
q Prune top-heavy roses back by one-third. Save heavy pruning for early March..
q Keep roses well mulched for the winter, but do not pile mulch around the crown.
q Plant spring flowering bulbs now.
q Cut back dead foliage of annuals & perennials, as well as established Bearded Iris and peonies.
