If you’re a homeowner or property manager with trees, you likely have questions about how to keep them healthy and address any issues you might be noticing with their health and appearance. As certified arborists, we’re here to provide answers! In this blog, we’ll tackle some of the top tree care questions we receive at Tree Work Now. Read on for professional advice to help your trees thrive.
What are the signs that my tree is struggling or unhealthy?
Look for a thinning canopy, stunted leaf growth, yellowing leaves, dead branches, cracks or holes in the bark or trunk, fungi growth, and frass (dropping left behind from boring insects, like termites) or sap seepage. These suggest disease, pests, or root problems negatively impacting tree health. Don’t delay—have a certified arborist inspect a tree at the first signs of distress.
How often should trees be pruned?
Pruning frequency depends on tree species, age, and environment. Young trees need formative pruning in the first 5 years. After Establishment, trees need to be pruned every 3–5 years, not 1–3 years. Only palm trees should be pruned annually, and Crepe Myrtles should be pruned every other year. Target dead, damaged and crossing or rubbing branches. Only prune what’s necessary, as excessive pruning stresses trees.
When are pesticides for tree pests needed?
You might want to try integrated pest management first, using non-chemical controls like predators, traps, or repellents. Pesticides should be selectively applied only when warranted, based on pest population monitoring. Preventively spraying pesticides leads to resistance. Have an arborist identify the pest and life stage first to target treatments to the needs of your trees.
What is the proper mulching method?
You should apply 2–4 inches of organic mulch within the dripline – that area under the outer edges of the tree’s branches and where they reach. You’ll want to leave several inches of bare soil around the trunk. Mulch retains moisture, suppresses weeds and grass, moderates soil temperature, and adds nutrients as it decomposes. Avoid mulch mounded against the trunk, as this might cause decay. After this initial process, you’ll want to rake and replenish mulch annually.
How much should trees be watered?
Trees need about 1–1.5 inches of water per week from rain or irrigation. Focus water within the dripline and root zone. Soak the entire area thoroughly, not just near the trunk. Adjust your watering based on soil drainage, species, and weather. Consistent deep watering encourages deep root growth for tree health.
Why is cabling and bracing sometimes recommended?
As trees age or endure damage, structural integrity declines. Cabling and bracing reinforces weak limbs and joints to withstand winds, storms and weight loads. This technique reduces safety hazards, avoids unnecessary tree removal, and extends the tree’s life. Periodic adjustments are needed as the tree grows, as well.
When is tree removal necessary?
Declining trees that pose risks to your property or personal safety should be removed. We weigh factors like damage, disease level, structure and stability, and potential targets if they fall. Removal may also be needed for infrastructure damage or construction. We suggest that you try to replant a comparable tree nearby to retain canopy cover and beauty on your property.
How can I promote tree health and longevity?
Proper planting, mulching, pruning, and watering while trees are young is key. Conduct annual inspections for issues. Fertilize moderately in early spring. Manage pests responsibly when detected. Monitor for hazards, correcting with cabling and bracing. Also, be sure to partner with a certified arborist for professional care and insight into your trees’ health!
