Important advice for autumn

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.

Don't miss these warning signs

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 tree threats

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.

Tree failures from summer storms

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.

Tree care recommendations for summer

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.

Critical care for trees

Now is a critical time of year to prepare your trees and shrubs for the coming summer. Healthy trees and shrubs are better able to withstand the higher temperatures and weather extremes that summer brings. Proper care in spring can help ensure the health of your landscape plants.

Tick management

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.

Beech leaf disease

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.

Emerald ash borer

Emerald Ash Borer continues to be a serious threat to ash trees in our area. Without intervention, tree death is swift and total. Do not wait for signs of damage. If you have ash trees, they should be treated in spring to prevent infestation.

Tree problems can cause long-term damage

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.

Prepare trees for spring

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.

Winter pruning

Winter is the ideal time to prune many tree species. Removal of dead or diseased branches this time of year can greatly reduce the risk they pose to your home and property. Plus, pruning can improve the overall health and appearance of your trees, getting them in shape for spring.

Winter tree inspection

Colder temperatures and shorter days serve as a reminder that it’s time for your trees and shrubs to have a winter check-up. Now is the time to uncover issues such as weakly attached branches, dead wood, diseases, pest infestations and other problems before they can cause serious damage in the spring.

Identifying hazardous tree conditions

As leaves fall from trees, the underlying architecture of the plant is revealed. This is the perfect opportunity to identify and correct visibly hazardous issues that can predispose trees to branch and tree failure such as dead wood and weakly attached limbs.
