  2. Dig a hole twice as wide as the root ball, but just as deep.
  3. Amend heavy clay soil with compost to improve drainage.
  4. Place the plant in the hole, ensuring the root flare is at soil level.
  5. Backfill the hole, gently firming the soil around the roots.
  6. Water thoroughly after planting and apply a layer of mulch.

Care Guide

Do

  • Mulch to conserve moisture and keep roots cool.

  • Water deeply during dry spells, especially in the first year.
  • Test soil pH and amend if necessary to be between 6.5 and 7.5.

Don't

  • Avoid planting in poorly drained, waterlogged soils.
