Street Tree Care Tips
Trees not only contribute to the neighborhood’s esthetic beauty; but also control air pollution and water run off, while moderating high summer temperatures.
Water
Probably the most important way to help your tree, is periodic, sufficient watering. There is really no
such thing as
too much water, but the recommended minimum amount is eight to ten gallons per week. Without proper
watering, trees will become stressed and may develop diseases and susceptibility to insect infestation.
One way to measure the proper amount is by leaving a hose dripping into the space for at least 1.5 hours. Or, fill two five-gallon buckets that have a few tiny holes in the bottoms for a measured, slow drip. If there is a good, soaking rain then you can take a holiday from the watering schedule, which should continue until the ground freezes.
Mulch
A layer of mulch (pine bark nuggets, cocoa mulch, wood shavings, etc.) around your tree will add
thermal protection, weed control and moisture retention. Use the donut technique—less than one
inch of mulch at the trunk then increasing it to two to three inches a few inches away and finally at least four
inches to cover all of the root ball. Salt applications resulting from snow removal from the street also end up on
the mulch. The mulch should be removed and changed in the spring.
Cleanliness
Remove all weeds and litter to increase curb appeal and discourage vandalism. Weeds rob your tree
of water, while dog excrement is toxic to the tree. In the spring get rid of sucker growth at the base of
the tree. Add ground cover, if desired, but avoid plants that might require a lot of additional water.
Protection
Tree guards, including wooden or metal fencing or posts can help protect your growing tree from opening car
doors and bumpers, bicycle locks, wayward garbage cans and dog litter.
