Owen’s Plant Health Care (PHC) is built on these simple foundations:

  • Preventive care
  • Frequent monitoring
  • Early detection
  • Integrated treatment programs

We offer Plant Health Care Programs to manage the spread of harmful insects and devastating diseases in your trees and shrubs.



Diplodia Tip Blight: Austrian, Scots, mugho, red and other 2 and 3-needled pines are susceptible to this fungus. Symptoms include the browning of needles on new shoots as the needles grow from the fascicle sheath. Lower branches on the tree are usually first to be infected.

Needle Cast: Needle cast is fungal disease that causes trees to shed needles. The symptoms first appear on needles as light green to yellow spots, which eventually turn red or brown. Growth of the fungus from the spots on the needle will cause the death of the entire needle.


Emerald Ash Borer: EAB is an aggressive exotic woodborer. It attacks stressed , as well as healthy ash trees. It is a very destructive pest and has caused the death of millions of ash trees. The earliest possible detection of this insect is essential to help reduce its spread and damage.

Bronze Birch Borer: The bronze birch borer is a wood boring beetle, similar to the emerald ash borer. It targets old stressed trees, boring underneath the bark and feeding off the sap. It starts at the top of the tree and works its way down.


Gypsy Moth: The gypsy moth is firmly established in southern Ontario. The larvae feed on several hundred different species of trees and shrubs but prefer oaks and poplars.

Leaf Miner: A leaf miner is the larva of an insect that lives in and eats the leaf tissue of plants.

Aphids: Aphids are small sap-sucking insects, and are among the most destructive insect pests on cultivated plants.

Tent Caterpillar: Tent caterpillars are readily recognized because they build silk tents in the branches of host trees. They make their tents in the nodes and branches of a tree's limb.

We also treat many other tree pest problems.
