What Is Westland Bonsai Potting Mix Enriched with Seramis?

The Westland Bonsai potting mix is formulated for the correct balance of drainage and water retention as well as aeration. This specially blended Bonsai soil encourages strong roots to support healthy Bonsai growth. Wood fibres combine with Seramis® to create an open soil structure with improved aeration, drainage and water management. This specialist Bonsai potting compost will supply your plant with all the nutrients it needs for the first 6-8 weeks. The resealable pouch is rigid, so it stands up on its own meaning it's simple to use, access and store.

Seramis provides water management as it absorbs and slowly releases water and dissolved nutrients. It promotes an open, porous soil structure that supports your plant’s root zone. It helps to avoid soil compaction and supports strong root growth. It works to increase airflow and humidity to create a beneficial microclimate.

The slimline, resealable pouch is designed to stand upright so it is easy to find on shelves or any cupboard or where space is tight.

Why Do I Need Westland Bonsai Potting Mix?

Each spring you’ll take your Bonsai tree out of its pot to inspect and trim the roots. This is also the time to see if the plant needs potting on and to refresh the Bonsai soil.

Even if you’re re-planting in the same Bonsai pot, you’ll want to refresh the potting mix. Tease out the Bonsai tree to inspect the roots and trim if necessary. When you’re done, add fresh Westland Bonsai potting compost and repot.

Garden tip:

  • When repotting, keep the Bonsai tree out of direct sun for around 3 weeks and water frequently to allow the roots to establish.

  • How Do I Use Westland Bonsai Potting Mix?

    The following procedure helps you to pot and re-pot your Bonsai plants:

    • If starting from fresh, select a young tree or shrub and pot it up in a small pot with Westland Bonsai Potting Mix and over the next 2–3 years regularly trim the roots and shoots.
    • When the bonsai tree is ready for transfer to its permanent container, fill the container with Westland Bonsai Potting Mix and secure the tree in the pot with wire.
    • Before planting, trim the roots so they fit into the container without having to be bent or forced.
    • Keep the plant out of the sun and water frequently to allow it to recover.
    • Each spring, take your bonsai out of its pot and inspect the roots to see if it needs potting on.
    • If replanting in the same pot, tease out the old compost and trim roots before adding fresh Westland Bonsai Potting Mix.
    • Keep it out of the sun and water frequently to allow it to recover.

    How Do I Feed and Water My Bonsai Tree?

    Watering Your Bonsai Tree

    Water once or even twice a day during summer, but less frequently in winter. Always ensure that excess water can drain freely to avoid root damage.

    Feeding Your Bonsai Tree

    Westland Bonsai Potting Mix will supply your plants with all the nutrients they need for the first 6–8 weeks. During spring and early summer, feed your plant with a specialist Bonsai Feed every two weeks.
