Planting

How to Grow

  1. Choose a site with morning sun and afternoon shade.
  2. Ensure soil is acidic, rich in organic matter, and well-drained.
  3. Dig a hole twice as wide and just as deep as the root ball.
  4. Plant high, with the top of the root ball slightly above soil level.
  5. Backfill with amended soil and water thoroughly to settle.
  6. Mulch with 2-3 inches of pine bark or compost, away from the trunk.

Pro Tip

Plant in a location protected from harsh winter winds and hot afternoon sun to prevent damage to leaves and flower buds.
