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.

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.

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.

Summer storms often cause branches or entire trees to fall. Preventative care can help you maintain your landscape while mitigating the possibility of unanticipated costs.

Given the likelihood of encountering ticks, it is important to know that controlling tick populations in your landscape is possible. The first step is assessing your landscape for common habitats like wooded areas, leaf litter and ornamental beds. Based on the assessment, treatments can specifically target at-risk areas.

Root problems including phytophthora root rot disease will be common in our area this spring. The severity of root rot varies. It can develop slowly or result in rapid death of the plant. Given the disease’s variable nature, it is important to identify and treat for root rot before it progresses.

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.

In spring, damaging tree borers such as ambrosia beetles will start feeding inside tree roots and branches or tunneling beneath the bark. These pests cause signficant internal damage. Taking action in spring is the best way to prevent a major infestation.

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.
