Ligustrum Bonsai pruning & trimming

Ligustrum is a fast-grower, and as a result, you must be very observant about trimming new growths. A ligustrum tree can produce about 7 or more clusters of leaves as new growth at once (that is how fast they can grow). Hence, you must always trim these new sprouts back, leaving only about two leaves on each new growth cluster.

All noticeable suckers found near the base of the tree should be completely pruned off because they usually prevent nutrients from getting to the leaves at the very top of the ligustrum tree. The best time to prune your Ligustrum tree is early spring before new growths start to emerge.
