Tree Feeding, Disease & Insect Control

About Our Tree Feeding & Insect Control Services

Healthy trees start below the surface. Many trees in Montgomery County are stressed not by disease itself but by compacted urban soil, low nutrient levels, and pest pressure. Rock Creek Tree uses injection feeding, deep-root fertilization, and targeted insect and disease treatments to protect the trees you want to keep.

Emerald Ash Borer Prevention & Treatment: if you have an ash tree on your property and it’s showing any thinning, dieback, or D-shaped holes in the bark, it is almost certainly being attacked by EAB. We have already removed thousands of EAB-killed ash trees across the region. Preventative injection treatment can save a healthy ash tree for a fraction of the cost of removal.
