I'd never grown king oysters before and they're impossible to find in the shops where I live, so I gave this a go, based on the success I'd had with other Merryhill kits. Really good value, a decent crop, and above all, they're fresh – you really can taste the difference. I'll be getting another kit.

It's the second time I've ordered the King Oyster growing kit from Merryhill Mushrooms and again, the kit delivered 2 bumper crops of mushrooms. The first flush grew in a few days and it's so much fun to watch them grow. The instructions are easy to follow and are great value for money. And delicious!


Easy to use kit - I have bought it two times now and had fantastic results. Two big crops off the first kit and three (just, the third was just a very big lone mushroom) from the second kit. The mushrooms themselves are truly delicious. I fry them in a pretty hot pan, so they start to catch a little and get some colour - which results in a seriously 'meaty' flavour and excellent texture. Slice the chunky stalk into rounds for a vegan scallop alternative - I'm very much an omnivore - they are really very good. Highly recommended.

Why choose our kits?

Our ready growing mushroom kits stand out from other brands due to the fact that the mushroom growing process has been partially started.

This unique feature provides several advantages.

It eliminates the need to carry out the lengthy inoculation, saving time and effort. 

By receiving the kits at a stage where the kit is pre started, we can ensure the mycelium is healthy before shipping, ensuring healthy crops.

The riskiest part of mushroom growing is avoiding any contamination on the substrate during colonization, so we have taken care of this portion of the process, prior to dispatch.

 They are firm in texture and do not shrink much when cooked. Use all the stalk by cutting into strips down the length of stem. Delicious scored and pan fried as a vegan “bacon”. They can be grilled, sautéed, or stewed to be added to soups, stews, sauces, pasta, vegetable dishes, meats, and seafood. If prepared whole, allow a longer cooking time for this meaty mushroom, cook until brown.
