When there is a hanging branch or crack in a tree, it’s easy to see that a problem exists. Other issues may be more difficult to detect. Simple solutions can make a big difference. Pruning can lessen branch weight and wind resistance. Cables and brace rods can also be effective in helping to limit branch movement and protect trees.

Autumn tree fertilization begins with a soil test. Urban soils are often compacted and nutrient-poor, causing weak growth and increased pest issues. Testing identifies deficiencies so nutrients can be applied correctly, supporting root development, improving tree health, and preparing trees for strong spring growth.

Fertilization is the single most important proactive measure you can take in caring for your trees this season. Soil care and fertilization in autumn dramatically improve growing conditions and provide the nutrients required for vital tree root development.

Trees under stress display key symptoms indicating a serious problem may exist. This includes wilting or loss of leaves/needles, yellowing of leaves or browning of needles, premature autumn color, early leaf drop and sappy spots on branches. Correctly identifying the underlying cause is critical to addressing tree health issues.

Summer is a time of high activity for pests as well as tree diseases caused by fungi and other organisms. Some problems may be simply aesthetic, while others can be a real threat to tree health and vitality. As such, it is important to have an arborist check your trees to determine the underlying cause.

Given the stress from higher temperatures and lack of rainfall comon in summer, it is critical to water your trees and shrubs thoroughly. Applying a 3-4" layer of mulch, inspecting for pest infestations and scheduling fall fertilization can also help maintain tree health and vigor.

Beech leaf disease, has been spreading rapidly. As implied by the name, the disease attacks beech trees, one of the most commonly found trees in our area. Caused by microscopic worms called nematodes, the first sign of infection are discolored stripes between the veins of impacted leaves. As the disease progresses, the tree will show signs of stunted growth and yellowing leaves.

Now is the time to address tree health issues that are commonplace this time of year. Problems including browning on evergreen needles, damage to twigs and branches, cracks or splits in the bark and root issues should be identified in early spring, before serious damage occurs.

After winter ends, your trees and shrubs will be working hard to establish spring growth. A soil test in early spring can help determine the precise nutrients needed for that growth, yielding a fuller canopy and vibrant, health foliage.

Major snowfall is expected throughout the area. The added weight of snow or ice may increase the risk of dead branches falling. Heavy or long limbs, branches showing signs of decay, or those with a weak branch attachment are more vulnerable. This can also be an issue for evergreens, which have a large surface area to “hold” snow.
