Step by step

  1. On planting day

    Plant the Tree

    Plant at the same depth it grew in its pot, in a hole twice as wide as the root ball, 4 m from other trees. Firm and water well.

  2. 0–1 days after “Plant the Tree”

    Stake and Tie

    Drive a short stake in on the windward side and fix it with a soft tree tie. Loosen the tie each spring so it never cuts into the bark.

  3. 0–2 days after “Stake and Tie”

    Water In Deeply

    Soak the root area with a full can, then keep the soil moist (not wet) for the first few weeks.

  4. 7–21 days after “Water In Deeply”

    Mulch the Base

    Spread 5–8 cm of compost or bark mulch in a 1 m circle, keeping it clear of the trunk.
