Wainui Valley Mushrooms – Mushroom Compost

Give your garden a second life!

Made from spent oyster and Lion’s Mane mushroom substrate, our mushroom compost recycles organic growing materials into a useful addition to your garden soil.

How to use

• Vegetable & flower gardens: Start by mixing 1 part mushroom compost with 3 parts existing garden soil.

• Established plants: Apply a thin layer around plants, keeping it clear of stems and trunks.

• Pots & containers: Mix into a suitable potting mix rather than using it on its own.

• Seedlings: Use caution, as young plants are more sensitive to excess salts and nutrients.

A little goes a long way! Start with a modest amount and observe how your plants respond. Avoid using it neat for seed raising or direct planting until suitability has been confirmed.

Good for your garden. Better use of resources. Give spent mushroom substrate a new purpose in your patch!
