Step by step

  1. On planting day

    Plant the Tree

    Plant the mulberry at the same depth it grew in its pot, in a hole twice as wide as the root ball. Firm the soil and water well.

  2. Straight after “Plant the Tree”

    Stake and Tie

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

  3. 1 day after “Stake and Tie”

    Water In Deeply

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

  4. 7 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.

  5. 30 days after “Mulch the Base”

    First Feed

    Scatter a general-purpose fertiliser over the root area and water it in.

Every year

  • March
    Spring Mulch

    Spread well-rotted compost over the root area.

  • June
    Water in Dry Spells

    Young mulberries drop fruit if they dry out. Give a deep soak weekly in dry weather.

  • August
    Harvest Mulberries

    Berries ripen over several weeks and stain everything. Spread a sheet under the tree and shake the branches gently.

  • December
    Light Winter Pruning

    Mulberries bleed sap if cut in spring. Only remove dead or crossing branches, in early winter while fully dormant.
