Here are some watering tips:

1. For newly planted trees (planted one – three years ago):
   These trees are the most susceptible to damage/death due to inadequate water. But you should prioritize which trees to water by starting with those trees located in areas with limited soil – think street trees and those surrounded by/near concrete and curbs.
2. Water SLOWLY. When the ground is hard and dry – water will run off if too much is applied too quickly.
3. Place a hose a foot or so from the base of the tree and turn it on to a trickle. Let it run for an hour or two (or more), occasionally moving it the hose nozzle to provide water to the entire root zone of the tree. If you have a small sprinkler head you can use that to cover a wider area – but again turn it on low.
4. You can also water with a five gallon bucket that you have drilled some (five is sufficient) holes in the bottom about the diameter of a pencil lead. Place the bucket at the base of the tree, fill the bucket to the top with water, let it drain, move it slightly, and fill it again – up to five times.
5. If you can, place a mulch ring around the tree following the 3-3-3 rule: create a ring of mulch around your tree, 3 inches deep in a 3-foot radius from the trunk, making sure to leave a 3-inch space right around the tree trunk. Mulch keeps the water in the soil feeding the roots by slowing evaporation.
6. After you’ve saturated the soil around the tree, remember to do it again in 3 – 4 days’ time. If you are unsure about when to water again, check our Watering Alerts.

For Established trees:

1. During a drought or dry spell, all trees can use some water, especially street trees. If you have street trees in front of your home letting a hose drip onto its roots for a few hours will be a big help! Move the hose nozzle around every hour or so to water the entire area.

Thanks for your help!
