Deep Root Fertilization
Deep root fertilization is an important facet of mature tree care. Trees require certain nutrients (essential elements) to function and grow. In Northern Virginia, trees are often found growing in clay-dense soils that do not contain adequate nutrients for normal, healthy growth and development. Deep root fertilization can help to improve growth; however, if not applied astutely, it may not benefit the tree at all and may even adversely affect the tree. This is why it is sensible to hire a professional arborist to evaluate your trees on-site, and determine if deep root feeding would potentially invigorate your trees.
It is important to give your trees plenty of water (slow, using a soaker hose, or slow running hose) after any deep root fertilization, if rainfall does not meet or exceed 1″/week for the first 1 to 2 weeks after treatment
