Small leaf pewter has a strong germination ability and is easy to form too dense opposite branches, which can cause the phenomenon of neck stuck. In the nursery, measures such as sprouts and pruning should be taken in time to promote the growth of the main stem. It can also cut branches and raise stems to keep the stem-to-crown ratio at about 1:2.
