Good condition, planted a bed last autumn, lots of shrooms this spring, to many to keep up with

Many many kilos of tasty wine caps

I’ve had many many kilos of wine cap mushrooms from this spore:

They were layered in a dedicated wood chip and cardboard bed that was in partial shade and kept damp with rain water.

And a few hands thrown, superficially dug into vege beds.

BOTH produced carrier bags full of yummmmmy mushrooms.

The Wine caps have dried really well keeping their texture and taste.

Easy, fun and yum.

Wonderful and easy mushrooms to grow

I made a mushroom bed from hay, grass clippings and wood shavings and in two weeks the mushrooms just started popping up! They smell so nice and taste great.

Able to talk to the team - beginner grower

I was able to talk to the team and get advice before I purchased as I wanted to grow outdoors in a prepared bed.

It is a success, I have no fuss mushrooms growing on their own.

Many thanks for the great advice for growing this type and I am ready to set up another bed now and enjoy my 1st harvest.
