How to Plant a Tree: From Nursery Pot to Thriving Landscape

You've bought a beautiful potted tree and found the perfect spot in your yard. Now what? Follow this step-by-step photo guide to plant it correctly and give it the best start.

As the saying goes, "Dig a $100 hole for a $10 tree." Extra effort at planting pays off as the tree establishes and grows strongly.

When to Plant

Bare-root trees go in early spring while dormant. Potted trees can be planted anytime the ground is workable—avoid digging in very wet soil (especially heavy clay that compacts into a watertight tomb) or frozen, bone-dry ground. Otherwise, you're good to go.

Digging the Hole

Make the hole twice the pot's diameter (three times in poor soil or for prized specimens). Depth should match the rootball height, with sloping sides for drainage. Double-check placement for the tree's mature size before digging.

Planting Depth

Set the tree so a quarter to a third of the rootball sits above surrounding soil level—especially important in poorly draining clay. We plant all trees above grade and mound soil around them. Never plant deeper than it grew in the pot.

Dealing with Rootbound Trees

If roots circle the rootball, loosen and untangle them so they can spread outward. Alternatively, make several vertical slices an inch deep into the rootball to break the circling pattern. This prevents the tree from strangling itself.

Positioning the Tree

Take your time. Have a helper hold and rotate the tree while you view it from multiple angles and distances—including from decks or upstairs windows. Consider future branch structure and clearance. This is your best chance to orient the tree perfectly for decades.

Soil Amendments

Opinions differ: some say amendments help, others insist trees must adapt to native soil. In our heavy clay, we amend with 30–50% compost, bark fines, old potting mix, peat moss, or any composted organic material. We also add a handful of polymer moisture crystals to aid water retention.

Fertilizing

Most trees appreciate a dose of time-release fertilizer in the planting hole. Watering in with half-strength water-soluble fertilizer (like Miracle-Gro) or an additive like SuperThrive gives an initial boost.

Backfilling and Watering

Don't stomp soil. Instead, shovel amended soil around the tree, pausing two or three times to water thoroughly. This settles soil, eliminates air pockets, and gives the tree a good drink.

Mulching

Apply several inches of landscape mulch to suppress weeds and retain moisture. Keep mulch several inches away from the trunk on all sides to prevent pests and disease.

Staking

If unsure whether staking is needed, stake anyway. Place one stake on each side, run ropes from stakes to trunk, and protect bark with tubing or old garden hose. Use taut-line hitches for easy adjustment. Remove stakes and ropes after a season or two—leaving them risks girdling the tree as it grows.

Investing extra time in proper planting—planning placement, digging a generous hole, staking, and mulching—will be repaid a thousandfold as your tree becomes a prized landscape feature.
