How to Start It
★ Recommended for beginners
A kit is a block already filled with mushroom roots, ready to fruit. Cut it open the way the kit says, mist it twice a day and keep it on a counter out of direct sun, and the first mushrooms appear in 1 to 2 weeks.
Safety first: only eat mushrooms that grew from a kit or spawn you bought, right where you put it. Wild mushrooms, some of them deadly, can pop up in the same pots, logs or wood chips, so if one looks even a little different, don't eat it. Oyster mushrooms are the easiest mushroom to grow, ready in weeks rather than months, with no soil or garden needed. They come in flushes: a crop of mushrooms, a rest, then another crop.

Planting & Sprouting
Growing Tips
- 1Only ever eat mushrooms that grew from your own kit or spawn, and throw out any that look even a little different from the rest, because wild look-alikes, some of them deadly, can sprout in the same spot.
- 2Keep the block in bright, indirect light, never in direct sun.
- 3Mist the air around the block 2 to 3 times a day, or tent it loosely with a clear bag with a few holes, so the air stays moist.
- 4Give it fresh air every day, since stale air makes long stems and tiny caps.
- 5A cool room suits oysters, away from heaters and drafts.
- 6Once a block is used up, crumble it into your compost or garden, where it feeds the soil.

When to Pick
Cut the whole cluster just before the caps flatten and the edges start to curl up
How to Harvest
- 1Oyster mushrooms are ready when the caps are full size but the edges still curl down, before they flatten or turn up.
- 2Twist the whole cluster off at the base, or cut it with a knife.
- 3Pick a little early rather than late, since older caps drop clouds of spores (a fine dust) that can bother your nose.
- 4After picking, soak the block in cold water for a few hours, let it rest for a week or two and keep misting, and a second crop usually follows.
- 5Most kits give 2 to 3 crops before they are spent.
- 6Keep the mushrooms in a paper bag in the fridge and eat them cooked within a few days.
