When should I prune shrubs?
Spring-blooming shrubs should be pruned right after flowering, as they bloom on old wood. Summer-blooming shrubs can be pruned in late winter or early spring before new growth begins. Evergreen shrubs are best pruned in late spring. Avoid pruning in late summer or fall, as new growth may not harden before winter.
What are the best shrubs for privacy hedges?
Arborvitae, boxwood, privet, holly, and laurel are excellent hedge shrubs. For evergreen year-round privacy, choose arborvitae or holly. For a more natural look, consider mixed plantings of native shrubs like viburnum and serviceberry that also provide wildlife habitat.
How do I rejuvenate overgrown shrubs?
Many deciduous shrubs can be rejuvenated by cutting them back to 6-12 inches above ground in late winter. This drastic approach works well for forsythia, lilac, and spirea. For less aggressive renewal, remove one-third of the oldest stems each year for three years.
What shrubs grow well in shade?
Rhododendrons, azaleas, hydrangeas (especially oakleaf varieties), mountain laurel, and Japanese pieris are excellent shade-tolerant shrubs. Many viburnums and hollies also tolerate partial shade. Ensure shade-loving shrubs receive adequate moisture, as tree roots compete for water.
How far apart should I space shrubs?
Space shrubs at half their mature spread for a dense hedge, or at their full mature spread for individual specimens. For example, a shrub with a 6-foot mature spread should be planted 3 feet apart for a hedge or 6 feet apart for individual display. Always check mature size before planting.
