For Pleurotus djamor diverse substrates are considered suitable. The easiest is cultivation on straw, a better consistency, stronger colors and a better taste you get when cultivating on hardwood substrates. Rose mushrooms are so aggressive that they will colonize even unpasteurized straw (substrate) if only the inoculation rate is high enough. Stem inoculations of hardwoods are possible, but the cultures are not hardy. Do not bury such logs permanently in the ground, but bury them in a barrel to keep the culture mobile.
Except for temperature management, almost all species of Oysters do not differ greatly in terms of suitable substrates and methods. Read more on the subject at my offered oyster mushroom.
Swarm fruiting Pleurotus djamor through defined fruiting windows works better than exposing the substrate all over. In the photos you can see the advantages of reducing fruiting surface. Single holes or a few short cuts in substrate bags produce beautiful clusters with little waste. In hot climates grown on a minimal substrate of pure straw or with too much light, the fruiting bodies bleach quickly. With too little light, they do not form the color properly at all and then sometimes become only yellowish.
Ventilation in the fruiting room prevents later mold growth.
Caution: Coveted by insects and snails, also an extremely strong sporer.
They go about this by excreting digestive enzymes through the tips of root-like extensions called hyphae. The enzymes break down their food leaving a space filled with nutrients that the hyphae can continue growing into, absorbing, and digesting again as it feeds. The hyphae branch and grow into a thicker mass called a mycelium, which maximizes the surface area through which feeding can take place.
Pleurotus Djamor has been successfully grown from a variety of substrates including sawdust, newspaper shavings, and even rolls of toilet paper. If you’re interested in growing them yourself, kits are available online. I’m not about to endorse any of them myself, but you can google it if interested.
The oyster mushroom isn’t a picky fungi in nature either. Pleurotus will grow on a variety of woods.
