Flexuosa and var. Nana respond well to pruning and is often pruned back to its main trunk to promote new growth and to keep a tidy and dense canopy. Without pruning, the canopy can become thin. The species, in some circumstances - such as when grown on rocky, terraced terrain - can grow buttress roots, but seldom does in flat, sandy areas. Flexuosa trees can also have a twist or spiral effect in the bark of their main trunks that increases with age, usually evident in seedlings.
