Mulch is important to hold moisture for the tree, controls weeds and protects the root system. Use mulch around the base of a tree, but not up to the trunk. Mulch should only be a thin layer approximately 3 to 4 inches deep.
It’s important not to overwater your tree. Overwatering can cause the tree’s roots to rot, along with poor drainage. If this does occur, there’s fungicides and treatments that can be administered to mitigate the problem.
During dry periods, water once or twice a month. Use 10 gallons of water for each inch of the tree’s diameter. Water only when temperatures are above 40 degrees and there’s no snow on the ground.
When pruning your tree, it’s best to trim or prune a tree during its dormant season. Although you can technically prune a pine tree at any time, it is still better to do so when it is dormant. The only exception is when the tree limbs become a potential hazard.
