Check for bor­ers

Gardening Australia - - YOUR PLANNER -

Mon­i­tor na­tive trees reg­u­larly for tree borer, par­tic­u­larly eu­ca­lypts, aca­cias and melaleu­cas. Look for tell-tale signs such as pin­holes and saw­dust on the trunk and branches. Pok­ing a piece of wire deep into the holes is all that’s re­quired to kill the pest. If a branch shows signs of dieback due to se­vere in­fes­ta­tion, con­sider re­mov­ing all of the affected ma­te­rial, cut­ting back to a point where the wood is sound and healthy. If you have a large tree in need of at­ten­tion, call in a ar­borist. For more on bor­ers, turn to p77 for ‘Grubs any­one?’
