Ericaceous Mix — Peat-Free Growing Medium

A specially formulated acidic coco coir blend for acid-loving plants such as blueberries, azaleas, rhododendrons, camellias, and heathers. Delivers the low pH these plants demand — without a single gram of peat.

Good to know: Coco coir is also known in the trade as "coco peat" or "coir pith" — it is the fine, spongy material from coconut husks. Despite the name, it contains absolutely zero peat and is 100% peat-free.

Why Choose Our Ericaceous Mix?

Acid-loving plants suffer in standard compost because the pH is too high, locking out iron and causing yellowing leaves. Our Ericaceous Mix uses buffered coco coir adjusted to pH 4.5–5.5 — the ideal range for ericaceous plants — combined with coco husk chips for structure and aeration, plus a 6-month controlled-release fertiliser sachet included in every bag.

Key Features

  • Low pH formulation (4.5–5.5) — purpose-built for acid-loving plants, preventing iron chlorosis and nutrient lockout.
  • Buffered coco coir base — pre-treated to balance calcium and magnesium levels from day one.
  • Coco husk chips — add structure and air pockets, promoting strong root development and preventing waterlogging.
  • 6-month controlled-release fertiliser included — a separate sachet of slow-release nutrients is included in every bag. No additional feeding needed for 6 months.
  • Peat-free and sustainable — made from renewable coconut husk fibre, supporting the UK peat ban.

Perfect For

  • Blueberries, cranberries, and other acid-loving fruit
  • Azaleas, rhododendrons, and camellias
  • Heathers, pieris, and Japanese maples
  • Containers, raised beds, and garden borders for ericaceous planting

How to Use

Fill your pot or container with the Ericaceous Mix, leaving 2 cm from the rim. Plant your shrub or seedling, firming gently around the base. Water thoroughly after planting. For best results, use rainwater where possible — tap water in hard-water areas can gradually raise the pH over time.
