Prof. Charles Hartman, Ph.D.Keeping tree roots healthy prevents expensive tree problems and damage to structures. The application of essential methods and techniques allows for the development of a healthy underground root system. This promotes root growth and helps prevent the problems associated with surface roots. It also protects the roots from the effects of soil compaction and moisture stress. Routine care of trees helps maintain their stability during storms.
Watering Techniques
- Deep soaking weekly trains roots downward
- Avoid frequent light watering that encourages surface roots
- Use moisture meters to check 30cm depth saturation
Mulching Methods
- Apply 5-10cm wood chips in donut shape around trunk
- Never pile mulch against tree bark causing rot
- Refresh annually as organic matter decomposes
Protect critical root zones with physical prevention. Install root guards before all construction projects. Maintain a 1-meter clearance around the trunks of trees and shrubs. Compaction damage to roots can be minimized by limiting access to heavy equipment in the immediate area. These measures help oxygenate the roots and prevent suffocation before it starts.
Regularly inspect roots for signs of trouble. Look for surface roots lifting pavement. Watch for cracks in the soil around the trunks. Check for girdling roots before they strangle the trees. Early detection can prevent major problems. Correcting problems is always easier if they are detected early. Seek the help of the professionals when necessary.
Fertilize judiciously in early spring. Granular fertilizer should be broadcast over the root zone. Fertilize at the drip line, where the tree's feeder roots are located. Any deep root injection goes where there are no active roots. The surface application provides the best nutrition for the trees. This builds up the roots to resist diseases.
Use mycorrhizal fungi to help roots. These natural partners extend nutrient access. Apply spores while planting in urban soil. Annual applications help maintain the benefits of these symbiotic relationships. Trees achieve drought resistance. They absorb nutrients 100 times more efficiently.
