Why it’s bad Creates monocultures where little else will grow. Adults can have hundreds of seedlings nearby. Displaces local tree species.
Control Seedlings can be pulled out but saplings and mature trees have to be cut and poisoned. Multiple cuts around the trunk filled with poison within 10 seconds is quite effective.
Alternatives Replace with Native Elm (Aphananthe philippinensis) a hardy dry rainforest species, or Poison Peach (Trema tomentosa) both in the same plant family as Chinese Elm.
