Tree Watering – Fall Planted Trees

HOW To Water

Expect about 45 seconds of watering at a medium to strong flow rate per gallon of the original container size. So a 7-gallon tree, about 5 minutes. A 25 gallon tree, about 20 minutes. If the mulch is dry, it’ll take 2-3 minutes just to soak the mulch, so you need much more to moisten the soil below.

You can use a strong flow if you are hand watering. Divide the mulched area up into sections – spend a minute on each, go to the next & next, then repeat. If you get run-off under the mulch but haven’t watered that much, move to another section or stop watering for a few minutes to let it soak in.

Another option is to set your sprayer on a gentle flow and leave it spraying on each section of the mulched area. Move it every 5 minutes or if you see runoff. With a gentle flow it’ll take about 1.5 to 2 minutes per gallon of the original container size to water your tree. So a 25 gallon tree, about 40-50 minutes.

Remember: It’s better to water deeply and less often than shallowly and more often.

WHERE To Water

For the first 4 months the roots will be in the area of the container, for a 25 gallon tree this is about a 2 foot diameter. Though you want to water the entire mulched area, make sure you don’t miss watering this area.


  • Water in 1 week.
  • If the weather remains on the warm side, water every 2 weeks until it gets cold.
  • Once cold, water every month until the Spring warm-up.
  • During the Spring warm-up, water every 2 weeks.
  • Once the leaves are out and the weather is warm, water once per week until the weather cools off in the fall.
  • In the fall, water every 2 weeks until it gets cold.
  • At this point you shouldn’t need to water anymore except in hot weather dry spells. If you get one, water every 2 weeks to enhance the health of your tree.

Do I need to water in the event of RAIN?

Because the tree is new and due to the mulch, you’ll need to water even if it rains unless you get 2 inches of rain or more for the watering period.
