What are Borers

Borders attack fruit trees and a number of ornamental trees and shrubs. The grubs tunnel into the trunk or branches, leaving a mass of sawdust or gum oozing from the hole.  

 

Symptoms

Sawdust, oozing gum and holes in branches or trunks.

 

Plants impacted

  • Fruit trees
  • Ornamental trees and shrubs

 

How to protect your plants against Borers

Probe the hole with a piece of wire to destroy the grub.  Improve the plant’s growing conditions by fertilising, mulching and watering.
