Planting Container-Grown Trees and Shrubs: A Step-by-Step Guide

Container-grown plants dominate nursery shelves for good reason—they're available all season, easy to transport, and don't demand immediate planting like bare-root or balled-and-burlapped stock. Plus, you can often see flowers, fruit, or fall color before you buy.

Selecting Healthy Specimens

Look for vigorous foliage and strong shoots. Inspect leaves and stems for pests. The root system is harder to judge but critical: a small plant in a large pot may be recently up-potted and not well-rooted—keep it in the container until roots fill out. Conversely, a plant with roots circling the pot's interior, poking above the soil, or escaping through drainage holes is rootbound. Avoid these if possible; if you must buy one, tease the roots apart before planting.

Choosing Container Size

One- and 5-gallon pots are standard. Smaller plants catch up quickly—within three years, a 1-gallon plant often matches a 5-gallon one planted at the same time.

Removing the Plant

• Plastic or metal containers: Tap the bottom and sides sharply. If the root ball doesn't slide out, cut plastic pots with bypass pruners or metal cans with tin snips (watch for sharp edges).
• Pulp pots: Tear the pot away carefully to avoid root damage.

Planting Steps

1. Dig a hole as described in Planting bare-root shrubs and trees. Create a firm central plateau. Position the root ball so its top sits 1–2 inches above the surrounding grade.
2. Backfill with unamended native soil in stages, firming gently around roots as you go.
3. Form a soil berm to create a watering basin. Water gently, keeping the trunk and crown dry to deter fungal issues. Mulch around the plant, leaving a few inches of clearance around the stem or trunk.
