A newly planted tree needs deep watering about once a week, close to the root ball, while an established tree needs it less often but just as deep, spread out around the dripline. Both take about 10 gallons per inch of trunk diameter, applied slowly so it soaks 12 to 18 inches down.

Why does a newly planted tree need water more often?

Because its roots are still mostly within the root ball it was planted with, so it can draw water only from a small area. Until those roots grow out into the surrounding soil, the tree dries out faster than an established one.

How is a newly planted tree watered?

Slowly and weekly, over the root ball and just beyond it, with more frequent watering in sandy soil, where water drains quickly. Zipped around the trunk and refilled each week, a Treegator Original Slow Release Watering Bag releases that slow soak at the base.

How is an established tree watered?

Less often, once the top few inches of soil are dry, with water spread around the dripline, the ground beneath the outer edge of the branches, where its roots now reach. A soaker hose left running there for several hours soaks the soil without runoff. Where a hose is impractical, 5 to 6 Deep Drip 24" Tree Watering Stakes are driven into the ground around a well established tree.

Frequently Asked Questions

How much water does a tree with a 2 inch trunk need?

About 20 gallons per watering, at roughly 10 gallons per inch of trunk diameter.

When does a new tree count as established?

Usually after one to three growing seasons, once new roots have spread well beyond the original root ball, and longer for large transplants.

Should a new tree be watered right after planting?

Yes. A thorough soaking at planting settles the soil around the roots and removes air pockets.

How deep should mulch be around a new tree?

About 2 to 4 inches, kept away from the trunk.
