Step by step

  1. On planting day

    Plant

    Plant 40 cm along a post-and-wire row apart in weed-free, well-prepared soil enriched with compost, and water in well.

  2. 0–3 days after “Plant”

    Cut Canes to 25 cm

    After planting, cut each cane back to 25 cm. You lose this year's fruit but get strong new canes for next year.

  3. 7–21 days after “Cut Canes to 25 cm”

    Mulch

    Spread 5 cm of compost or bark around the plants to keep moisture in and weeds down.

    Spring Mulch and Feed

  • May
    Tie In New Canes

    Tie new canes to the support wires; remove weak ones and suckers far from the row.

  • June
    Net Against Birds

    Cover with netting as the fruit starts to colour.

  • July
    Pick Raspberries

    Pick every couple of days when berries pull easily off the plug.

    Starts from year 2.
