Pink Oyster

Pleurotus djamor

CulinaryBeginner

The pink oyster is the tropical member of the oyster family: it grows on fallen coconuts and palm fronds in the wild and does best warm, at around 25–30 °C.

Pleurotus djamor occurs in tropical and subtropical regions, reaching as far north as Japan and as far south as New Zealand, and in Hawaii it is often found on fallen coconuts and the stalks of palm fronds. It can be cultivated at relatively warm temperatures of 25–30 °C on barley straw, wheat straw, sawdust and even tea leaves. Reported biological efficiency in a compiled review was 62.5% on oak sawdust, 77% on paddy straw and 68.7–75.5% on wheat straw, with the highest efficiency at a 5% spawn rate in a trial of 1–5%.

How to grow Pink Oyster, step by step

Choose a substrate. Straw (wheat, barley or paddy) or sawdust, prepared and pasteurised.
Add spawn. Use grain spawn; up to about 5% of the substrate weight was best in the cited trial.
Keep it warm. Hold the bags in the warm 25–30 °C range reported for this species while the mycelium colonises.
Fruit and harvest. Provide fresh air, humidity and light once colonised and pick the clusters as they mature.

Growing notes

Warm conditions are the main difference from pearl and blue oysters, which fruit cooler. The substrate ratings on this page come from reported biological efficiency: stems of common beans (Phaseolus), safflower hay, paddy straw and wheat straw all gave about 68–78%, while leaf litter such as apple, poplar and chinar leaves gave much less. Because only limited fruiting-room data was found, check humidity and fresh-air needs against the pearl oyster page and your strain.

Questions about growing Pink Oyster

What temperature does the pink oyster need?

It can be grown at relatively warm temperatures of 25–30 °C, which suits tropical and subtropical climates.

What substrate does the pink oyster grow on?

Barley straw, wheat straw, paddy straw, sawdust and tea leaves are all reported. In a compiled review, biological efficiency was about 68–78% on straw and bean stems and 62.5% on oak sawdust.

How much spawn does it need?

In a trial comparing 1–5% spawn, the fastest spawn run and the highest biological efficiency came at 5%.

Where does the pink oyster grow in the wild?

In tropical and subtropical areas, as far north as Japan and as far south as New Zealand, for example on fallen coconuts and palm fronds in Hawaii.
