Tree Care – Recognizing the Signs of Poor Or Declining Tree Health

Tree Care includes the overall management of the health, safety and benefits of a property’s trees and shrubs. This requires an understanding of plant biology, soil conditions, fungi, insects and pests, and water supply and flow. It also requires a knowledge of proper pruning techniques and timing. This article will help you recognize some of the most common signs of poor or declining tree health, and provide tips for taking action.

Look for brittle branches or ones that snap easily when tapped. A good test is to scrape the bark with your fingernail and feel for a layer of green underneath. If the bark is completely brown or black, it indicates a lack of nutrient flow and a dead branch. A dead tree is a major safety hazard that can fall and damage your property or your neighbors.

Healthy trees have thick, consistent bundles of leaves throughout the canopy. If you see bare patches it could mean disease, insect infestation, machinery or wind damage, improper pruning, drought, soil compaction or lack of nutrients. Consult a certified arborist for advice.

Trees are constantly under stress from the environment. The best way to reduce this stress is to give them lots of water during dry spells. Water at least weekly, preferably in the early morning to slow evaporation. Be sure to water deeply, getting all the way down to the roots. Mulching helps conserve moisture as well.

Avoid fertilizers unless you are told to do so by a certified arborist. Over-fertilizing can harm the tree by promoting excessive vegetative growth and reducing root function. It can also encourage fungus and disease, which could lead to insect infestation or death.

A tree’s crown is made up of both leaves and twigs that offer shade to the roots and absorb sunlight for photosynthesis. It is very important that the leaves and twigs remain healthy to prevent overheating, scorching and a lack of nutrient absorption.

If a tree looks wilted, yellow or brown it’s not getting enough water. If a tree is in severe stress it may have no twigs or leaves at all, which can be a sign of a serious problem and is usually a very good reason to call a professional.

Proper pruning can be very beneficial for a tree, extending its life and improving appearance. However, it must be done at the right time, as trees have different needs depending on the season. Trimming is best done in the spring and summer to promote healing and minimize stress, or during the dormant season in winter. Always use a professional who is certified by a recognized organization such as TCIA (Tree Care Industry Association) and has an understanding of the local ecosystem, soils, insects, diseases, and other factors that influence tree health. It is also a good idea to check for certifications on contractors’ websites or through an online search. Be wary of any professional who advertises “topping” as a service – this practice is harmful, injures the tree and leads to weak branches prone to failure.
