Does Planting Depth Really Matter?
You’d be surprised how many people assume trees are inherently sturdy and can thrive no matter how you plant them. “They’ll adapt,” some say, but this is far from the truth.
When buried too deeply, critical structures like the root flare (where the trunk widens at the base) can suffocate, leading to girdling roots or improper oxygen exchange. Conversely, planting too shallow exposes roots to harsh elements and dries them out.
How Deep Should You Plant a Tree Properly?
Consider following reputable tree planting guidelines and best practices to give your specimen the best chance to thrive.
Finding the Root Flare
If you want to know how to determine the correct tree planting depth, locate the rootball and clearly identify the root flare first. This is the part of the tree where the trunk transitions into the roots and must remain just above ground level after planting. You may need to remove excess soil from the top of the rootball to uncover it.
Digging the Hole
Aim to dig a saucer-shaped hole that’s two to three times wider than the diameter of the rootball, but no deeper than its height. This width provides room for roots to grow outward, while controlling depth ensures the root flare won’t become buried.
A good rule of thumb is that the top of the rootball should sit just slightly above ground level to allow for settling.
Preparing the Soil
Resist the temptation to overdo it with amendments after gauging the proper tree planting depth for healthy growth. Instead, loosen the surrounding soil to reduce compaction and help young roots establish themselves.
Backfilling the Tree
When it’s time to backfill, go slow and steady. Use the soil you originally removed to fill around the rootball, gently tamping it down to eliminate air pockets. Avoid compressing the soil too much. It’s about striking a balance where the tree is stable, but the roots can still breathe.
Mulching and Watering
Apply a two- to four-inch layer of organic mulch around the base of the tree, but never pile it against the trunk (a mistake known as “volcano mulching”). Follow this with a deep, soaking water to help settle the soil and provide hydration to the tree’s roots.
