How to Plant a Holly Bush
Get holly planted correctly and it will thrive for decades with little help. The essentials are acidic, well-drained soil, the right depth, and — for berries — a male holly within pollinating distance.
When and where to plant
Holly is best planted in fall or early spring, when the soil is workable and the weather is mild enough for roots to establish before summer heat or winter cold. Most hollies want full sun to part shade — full sun produces the densest growth and the heaviest berry set — in acidic, moist, well-drained soil. Avoid heavy, waterlogged ground unless you are planting a wet-tolerant species such as winterberry or inkberry.
How to plant a holly, step by step
- Dig a wide hole. Make the hole two to three times as wide as the root ball but no deeper than it is tall, so the plant sits on firm ground and will not sink.
- Check the depth. Set the holly so the root flare — where the trunk widens into roots — sits at or slightly above the surrounding soil line.
- Loosen the roots. Tease apart circling or pot-bound roots so they grow outward into the native soil rather than strangling the plant.
- Backfill with native soil. Fill around the root ball with the soil you removed, firming gently to remove air pockets; avoid heavy amendments that create a bathtub effect in clay.
- Water deeply. Soak the plant in thoroughly to settle the soil and hydrate the roots.
- Mulch. Spread two to three inches of organic mulch over the root zone, kept a few inches back from the trunk, to hold moisture and moderate soil temperature.
After planting
Water regularly through the first one to two growing seasons while the roots establish, especially in dry spells — holly is drought-tolerant only once settled in. Hold off on heavy feeding at planting; wait until the plant is actively growing, then feed lightly with an acid-forming fertilizer.
