Pruning Heather

Heather requires annual pruning to stay compact, floriferous, and tidy. Without it, plants become leggy, woody at the base, and flower poorly. Prune in March or April, just as new growth begins to show but before it extends fully. Pruning too late removes the developing flower buds; too early and frost may damage fresh cuts. Use sharp hand shears or secateurs—hedge trimmers work well for large drifts but can look brutal on individual specimens. Remove the previous year's flowering shoots, cutting back to just below the old flower spikes and into the green foliage beneath. Take off roughly one-third to half the top growth, but never cut into old, bare wood lower down; heather will not regenerate from leafless brown stems and you risk killing the plant. The aim is to trim lightly into the leafy growth, encouraging dense branching and abundant late-summer and autumn flowers. If you inherit an old, neglected heather that has become sparse and woody, replacement is usually more successful than renovation. Young plants establish quickly and will outperform a struggling veteran within two seasons. After pruning, rake off the clippings to prevent a matted layer smothering new shoots. No other pruning is needed through the year. Deadheading spent flowers is unnecessary—the dried blooms often provide winter interest and structure, and spring pruning removes them anyway. Focus your effort on that single annual trim in early spring.
