What is deep-root feeding and why do Treasure Valley trees need it?
Treasure Valley soil is alkaline enough to lock up iron and other micronutrients, which is why so many local maples, oaks, and ornamentals show yellow leaves with green veins (iron chlorosis). Our deep-root feeding injects nutrients — including chelated iron — directly into the root zone where trees can actually use them.
Insect & Disease Applications
Aphids, spider mites, scale, borers, and fungal diseases all hit valley landscapes hard in different seasons. We inspect, identify the specific problem, and apply targeted treatments — not blanket sprays. Common programs include:
- Aphid and honeydew control on maples, ash, and lindens
- Spider mite treatments on evergreens during hot, dry stretches
- Borer prevention on stressed birch and aspen
- Fungal disease applications timed to spring leaf-out
What does a dormant oil treatment do?
Applied in late winter before bud break, dormant oil smothers overwintering insects and eggs — knocking down aphid, mite, and scale populations before the season starts. It's the highest-leverage, lowest-impact treatment in tree care, and the window for it is short.
Fall Feeding
Just like turf, trees and shrubs build root reserves in fall. A fall root-zone feeding helps them winter well and push strong, healthy growth in spring.
Pruning & Removal
We prune for structure, health, and clearance — and when a tree is beyond saving, we handle tree removal safely. Ask about pruning during your free estimate; winter is often the best time for structural work.
Frequently Asked Questions
What is dormant oil and when should it be applied?
A horticultural oil applied in late winter before buds break. It smothers overwintering insects and eggs — aphids, mites, scale — reducing pest pressure all season with minimal impact on beneficial insects.
Why are my tree's leaves turning yellow?
Yellow leaves with green veins usually mean iron chlorosis, which is widespread here because alkaline soil locks up iron. Deep-root feeding with chelated iron restores color and vigor. We confirm the diagnosis during a free inspection.
