The success of your newly planted tree is contingent to your consistent watering over the next 2-3 growing seasons and the care around the base of the tree. The tree will be planted using composted wood chips and will either be watered using gator bags or watered periodically throughout the hot months of the year by the Parks and Recreation Department. While the town will water the new trees on hot days, it will also be pertinent that the home owner water the tree periodically as well. Any unforeseen circumstances (thunder storms, short staff, etc) could direct the focus of the department in another direction, leaving the periodic watering fully up to the home owner. It cannot be over stated how important it is to make sure your new tree gets water.
Preferably, your new tree should receive about 10 gallons of water twice a week and even a third time during really hot times of the year. The theory behind watering a new tree flows like so: less frequent thorough watering is more beneficial to root development than more frequent shallow watering. The less frequent thorough watering will allow water to get to all the roots (instead of just the roots near the surface) and will reduce the chances of over watering the tree. Over watering the tree will cause a reduction of oxygen to the roots and can be just as problematic as under watering a tree.
The composted wood chips around the tree will be provided by the town upon planting the tree. Please do not add or remove any of the mulch. The mulch is put down to help the tree. Anymore or less could harm the tree. Mulch has a multitude of benefits including increases in available nutrients, water retention, buffers soil temperatures and provides root protection. Mulch also reduces root-zone erosion potential, soil compaction, weed growth, and prevents lawnmower and other machinery from getting close to the tree and damaging it.
Some minor pruning to branches that have been damage during the planting process may be necessary shortly after planting the tree. It is recommended that any corrective pruning wait until after at least one growing season.
