How to grow Japanese buckthorn for the first time

8steps

Start with Japanese buckthorn as a simple, low-maintenance tree for your garden.

  1. 1

    What you'll need

    A young Japanese buckthorn sapling and some basic gardening tools like a trowel.

  2. 2

    Best time to plant

    Plant in early spring or late fall when the soil is moist and workable.

  3. 3

    Soil and container prep

    Ensure your garden has well-draining, medium-rich soil. For containers, use a mix of light sand, medium soil, and heavy clay with added compost.

  4. 4

    Sowing or transplanting

    Transplant the young sapling by digging a hole twice as wide but not deeper than its root ball.

  5. 5

    First two weeks

    Water regularly to keep the soil moist. Avoid overwatering, which can lead to root rot.

  6. 6

    Ongoing care

    Provide full sun or partial shade and water when the top inch of soil feels dry. Prune in late winter to maintain shape.

  7. 7

    Harvest or pruning

    Focus on pruning during late winter to remove any dead, weak, or crossing branches for better air circulation.
