Key takeaways
- In the wild, Oyster mushrooms grow on dead hardwood.
- Their mycelium can trap and digest tiny nematodes.
- Growers use straw, sawdust and other substrates.
- They colonise quickly and fruit generously.
Oyster mushrooms are among the easiest mushrooms to grow, in the wild and in cultivation. This article explains how.
In the wild
Oyster mushrooms grow on dead or dying hardwood, especially beech, often in autumn and winter. They are white-rot fungi, breaking down wood. See How Fungi Decompose Wood.
A carnivorous twist
Oyster mushroom mycelium can trap and digest tiny nematode worms, supplementing its nitrogen supply on nutrient-poor wood.
In cultivation
- Substrate preparation: straw, sawdust or other material is pasteurised or sterilised.
- Inoculation: spawn (grain colonised by mycelium) is mixed in.
- Colonisation: mycelium spreads through the substrate.
- Fruiting: fresh air, humidity and light trigger clusters of mushrooms.
- Harvest: clusters are picked as the caps open.

Why they’re popular with growers
They colonise quickly, tolerate a range of substrates and produce generous harvests, which makes them a favourite with both small and large growers. See Oyster Mushrooms and Sustainable Cultivation.
