Mature Oak Care

Oaks trees are native to our area and can live 200 to 300 years. Oaks have been the subject of story, song, and legend. They cannot be replaced with in our or our children’s lifetime.

Mature oaks create a dimension in the landscape that is often taken for granted, because they have been there so long. They may appear indestructible because we see only the toughest part of the tree that is above ground. However the most sensitive portion of a mature tree is the root system.

Maintaining mature oaks in landscapes may be a complicated process because of many factors discussed below. A preventive care program is like putting money in the bank. An effective program includes regular inspection and necessary care to detect and correct problems before they can become damaging or fatal.

We treat each tree according to its individual requirements for healthy growth and long term development. We evaluate and try to understand the actual condition and physical limitations of each tree. Then we focus on developing and maximizing the above and below ground conditions to meet the optimum growth and longevity for your trees.

This starts with your Certified Arborist inspecting your tree(s) to detect any changes in the trees health or condition before a problem becomes too serious. All visible characteristics of the tree are checked. These include: leaf size, condition, color, distribution and density; branch structure and condition; signs of decay or decline; and site impact assessment. Any abnormalities are noted and closely watched. An integrated program is then developed to improve or maintain your oaks vitality.

Mature oaks have an expansive root system that can extend two to three times the distance of the leaf canopy. Major portions of the actively growing roots are located outside the trees’ drip line. This affects fertilization, care, watering, and construction practices and impact.

Start with the basics to maintain your tree:

·         Pruning should be done on a regular cycle to remove deadwood, improve the structure, enhance vigor, and maintain safety.

·         Water 1”/week if no precipitation, always check soil moisture before watering

·         Mulch 2”-4” deep with organic mulch over as much of the root zone as possible

·         Manage insect pests and/or diseases

·         Fertilize as recommended by your arborist

·         Maintain the root system by protecting trees from construction damage, use of mycorrhizea, root stimulants, compost teas, growth regulators or radial trenching as prescribed

Just as with people, the care and issues of a mature tree differ from that of a young tree. We look forward to utilizing our years of experience and knowledge to help maintain your mature oak. We get excited about all trees, but these denizens often hold a special place for us, you and the environment that are worth maintaining.
