Winter Desiccation

Species: Conifers


Adults spend the winter in the duff at the base of the tree. In spring time the adults crawl or fly to the terminal leader to mate and lay eggs. The eggs will hatch and the larvae will mature and feed on the inside of the tree. In August adults will emerge to feed on the outside of the tree before heading to the ground to seek winter shelter.


Establishing a fall watering program to boost tree moisture levels is important. Establish mulch in the drip zone if lacking. Cambistat can be used for chronic issues to harden the petiole of the needle and reduce evaporative water loss. Root growth stimulants will increase water absorption in the root zone.
