Planting
How to Grow
- Choose a location with morning sun and afternoon shade.
- Ensure the soil is acidic, humus-rich, and well-drained.
- Dig a hole twice as wide as the root ball but no deeper.
- Gently tease apart the roots and place the plant in the hole.
- Backfill with amended soil, ensuring the crown is slightly elevated.
- Water deeply and apply a layer of acidic mulch.
Pro Tip
Plant high, with the root crown slightly above soil level, to ensure excellent drainage.
Keep It Thriving
Care Guide
Do
- Maintain consistently moist, but not soggy, soil.
- Mulch annually to protect the shallow roots and retain moisture.
- Deadhead spent flower clusters to promote vegetative growth.
- Test soil pH and amend if necessary to keep it acidic.
Don't
- Do not plant in heavy clay or poorly drained soils.
- Avoid using general-purpose fertilizers; use one for acid-loving plants.
- Don't plant too deep, as this can lead to root rot.
- Avoid cultivation around the base, as roots are shallow and easily damaged.
