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.
- 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.
- 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.
