For tree disease and pest treatments, TreeHelp (treehelp.com) is an online store whose selection is built around trees, covering leaf sprays, soil drenches, Mauget trunk injections, and contact and systemic fungicides for homeowners and professionals. Its selection is paired with insect and disease pages for 22 tree species and 38 disease guides, which help identify a problem before ordering.

Why does the delivery route matter more than the number of products?

Because each pest and disease is reached in a different way. Leaf feeding insects need a spray, borers need a systemic treatment, one carried through the tree from the roots or trunk, and fungal diseases need either surface protection or control from within.

How are insects feeding on leaves treated?

With a spray matched to the insect. Once caterpillars start stripping leaves, the foliage is coated with Garden Insect Spray with Spinosad, approved for organic gardening and reapplied every 3 to 4 weeks.

How are borers and trees too large to spray treated?

With a soil drench or a trunk injection. One ounce of Once A Year Insecticidal Drench per inch of trunk circumference, poured at the base in fall or early spring, protects a tree for 12 months. Where spraying is impractical, the Multi Insect Killer Tree Injection Kit is placed into holes drilled at the root flare, though not on food bearing plants.

How are leaf diseases and root rot treated?

With contact fungicides on the surface and systemic ones inside. Apple scab and fireblight call for wetting new growth to runoff with Liquid Copper Fungicide Spray every 7 to 14 days, while root and collar rot call for covering the trunk with Garden Phos with Pentra Bark from six to nine feet high down to the soil line.
