Wool compost booster

New
Product Image
A good, healthy compost heap relies on the right blend of ingredients and plenty of microbial activity. This premium compost booster is designed to give the natural composting process a helping hand.

It’s made from straw and plant-based digestate pellets with added wool fertiliser. Together they provide slow-release nitrogen and organic matter to encourage the bacteria and fungi that break down garden and kitchen waste.

The wool fibres also absorb excess water and improve airflow so the heap doesn’t get too wet or compacted. Microbes stay active and thriving, keeping the composting process going even in colder or wetter weather.

Suitable for use in compost heaps, bins and tumblers.

Key features:

  • Compost activator with added wool fertiliser
  • Speeds up decomposition - ideal for slow, cold or wet compost heaps
  • Supports beneficial bacteria and fungi that break down waste
  • Helps create richer, more nutrient-dense compost
