How to Prune Nandina for a Healthier, More Attractive Shrub

The best time to prune nandina (heavenly bamboo) is during winter dormancy. This timing minimizes stress and allows the plant to redirect energy into vigorous spring growth. According to Texas A&M University horticulturists, a strategic thinning approach yields the best results: remove about one-quarter of the oldest stems completely at ground level. Then, on one out of every four remaining stems, cut back roughly one-third of the total height. Next, reduce another quarter of the stems by two-thirds of their height. Leave the final quarter of stems uncut. This staggered method maintains the shrub's natural form while encouraging fresh, dense foliage from the base.
