Emerald Ash Borer

This invasive beetle doesn’t knock, it devastates. Once inside an Ash tree, EAB larvae tunnel through the wood, cutting off nutrients and slowly killing the tree. If you have Ash trees and haven't treated them, they're vulnerable, especially in known outbreak zones like Boulder, Arvada, Denver.

Elm Leaf Beetle

These pests chew through leaf tissue, creating holes and rapid defoliation. Dense populations can severely weaken a tree’s health and resilience—especially during dry spells.

Japanese Beetle

They don’t nibble—they swarm. Japanese Beetles skeletonize foliage across ornamentals, turf, and flowers, leaving destruction in their wake during midsummer. Their feeding can strip entire trees in days.

Aphids

They’re tiny, but they multiply rapidly and often bring viruses along. Curling leaves, stunted growth, and shoot dieback mean aphids have settled in. They target new, tender growth—and can sap a plant’s energy silently for weeks.

Chlorosis

Chlorosis is commonly caused by deficiencies in micronutrients such as iron or magnesium, resulting in reduced chlorophyll production and yellowing leaves. Treatment varies depending on soil composition and nutrient availability. Our certified arborists specialize in tailoring effective recovery plans for each unique situation.

Fireblight

Fire Blight is an aggressive bacterial disease frequently affecting Apple, Crabapple, and Pear trees. It can impact every part of the tree—from leaves that rapidly wilt and blacken to fruit that shrivels and dries. Left unchecked, it can invade the trunk and roots, often resulting in total tree loss.

Anthracnose

Caused by several types of fungi, Anthracnose often affects Ash, Maple, Elm, Sycamore, and other deciduous trees—particularly during cool, wet seasons. It typically appears as leaf blight and may lead to premature leaf drop, weakening the tree over time.

Nipplegall

Nipplegall formations on Hackberry trees are caused by Psyllid insects that feed on leaf tissue. Gall shape and concentration can vary by species. While generally cosmetic, heavy infestations may trigger early defoliation and weaken overall tree health.
