Besides proper watering, the best thing you can do for your trees is to apply mulch over their root systems.

How to apply mulch:
- Apply mulch as needed to maintain 3-4 inches deep
- Keep mulch 4-5 inches away from the base of the tree

Benefits of mulch:
- Insulates the soil and roots from extreme temperatures
- Slows soil moisture evaporation, which extends the amount of time between watering
- Mimics the forest floor. The decomposition of the organic matter in the mulch (in addition to any existing compost) will release nutrients that become available to be absorbed by the roots

- Reduces weed and grass competition. Turf conflicts with the presence of trees because they compete for the same resources

- Provides a buffer between the turf and tree to help protect the trunk and surface roots from mower and equipment damage. Wounds at the base of the trees cause lifelong problems
