How to Start It
★ Recommended for beginners
A pre-colonised block that fruits within 1–2 weeks of opening — the no-fuss way to learn, ideal indoors on a kitchen counter.
The perfect first mushroom: fast, vigorous, and forgiving. Oysters fruit in WEEKS (not months) and will colonise almost anything — straw, sawdust, even spent coffee grounds. They fruit in 'flushes': a cluster of mushrooms, a rest, then another. Grown indoors or in deep shade, they need high humidity, fresh air, and indirect light. No garden or soil required.

Planting & Sprouting
Growing Tips
- 1Two things make or break oysters: humidity and fresh air.
- 2Mist around them often (or tent loosely) to keep the air moist, but give daily fresh air or the stems grow long and the caps stay tiny.
- 3Keep them out of direct sun.
- 4After each flush, soak/rest the block — most kits give 2–3 harvests before they're spent and ready for the compost.

When to Pick
Cut the whole cluster just before the caps flatten and the edges start to curl up
How to Harvest
- 1Harvest the entire cluster by twisting or cutting at the base just as the caps reach full size but before the edges flatten and turn upward (they release a lot of spores once mature).
- 2After a flush, rest the block, keep it damp, and a second and third flush usually follow.
