Planting
How to Grow
- Select a site that receives at least 6 hours of direct sun daily.
- Ensure the soil is well-drained; amend heavy clay if necessary.
- Dig a hole twice the width of the root ball.
- Position the plant with the top of the root ball level with the soil.
- Backfill with the original soil, firming it gently.
- Water deeply after planting and weekly for the first year.
Pro Tip
Give it space to achieve its natural arching form; shearing ruins its graceful habit.
Keep It Thriving
Care Guide
Do
- Plant in full sun for the best density and color.
- Provide good air circulation to prevent fungal issues.
- Water deeply but infrequently once established.
- Mulch to conserve moisture and keep weeds down.
Don't
- Do not plant in poorly drained or consistently wet soil.
- Avoid heavy pruning or shearing, which destroys its natural form.
- Don't plant too close to other plants or structures; allow for its mature spread.
- Avoid planting near apple or crabapple trees to prevent cedar-apple rust.
