Site heavenly bamboo in full sun or partial shade in soil that stays moist but not soggy. Nandinas are not particular as to the type of soil or its pH. The foliage takes on a reddish tint in full sun.
Feed nandinas each spring with a fertilizer formulated for shrubs. Follow package directions carefully as too much fertilizer will damage the shrub. Always apply fertilizer to moist soil.
Mulch over the root zone with 2 to 3 inches of organic material such as bark chips or straw. This discourages weeds and helps keep the roots moist.
Inspect the shrub occasionally for signs of insects or diseases, although nandinas are rarely bothered by either.
Prune nandinas early in the spring when the shrubs begin to leaf out. First prune away all winter-damaged wood, then cut back the old canes at staggered heights. Nandinas become leggy and bare on the bottom if left unpruned.
