Signs Your Trees Might Be in Trouble

It’s important to keep an eye on your trees for signs of health issues. Watch for these common indicators of pest infestations or diseases:

  • Unusual leaf discoloration or early leaf drop
  • Dead or dying branches, especially in the upper crown
  • Peeling or cracking bark
  • Visible insects or fungi on the trunk, branches, or leaves
  • Stunted growth or misshapen leaves
  • Holes in leaves or bark
  • Oozing sap or unusual growths on the trunk or branches

If you spot any of these signs, give us a call. The sooner we can diagnose and treat the problem, the better chance we have of saving your tree.

How We Tackle Tree Pests and Diseases

Our approach to tree health is comprehensive and tailored to each situation. Here’s how we help keep your trees in top shape:

  1. Tree Injections

    We use specialized injections to deliver treatments directly into the tree’s vascular system. This method is highly effective for issues like oak gall, emerald ash borer, and maple wilt.

  2. Targeted Sprays

    For certain pests and diseases, we apply carefully selected sprays to the affected areas. This includes treatments for spring fungicide on ornamental and fruit trees.

  3. Deep Root Fertilization 

    Sometimes, trees just need a boost. We offer deep root fertilization to add essential nutrients back into the soil, helping maintain overall tree health and resilience.

  4. Proactive Care 

    The best defense is a good offense. We offer preventative treatments and regular check-ups to catch potential issues before they become big problems.
