It’s historically dry out there, the time to water is now! Here are some watering tips:
For newly planted trees (planted 1 – 3 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.
- Water SLOWLY. The ground is hard and dry – water will run off if too much is applied too quickly.
- 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 to low.
- You can also water with a 5 gallon bucket that you have drilled some (5 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 5 times.
- If you can, place a mulch ring around the tree following the 3-3-3 rule (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.
- 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:
- All trees in this drought 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.
- The rule of thumb in these severe conditions is: WATER!
