    Hi everyone
    I have collected some mushroom compost for two new no dig beds in which I intend to sow my potatoes. However it is very fresh. Is it ok to plant potatoes as shown in Charles’ video making a small slit into this compost even though it has not had time to decompose? It looks like a mixture of rotted manure, straw and possibly peat and still has one or two mushrooms growing in it.
    Thanks for any advice.

    I believe mushroom compost is quite alkaline because of the lime (please correct if I’m wrong) and alkaline soils can encourage scab on potatoes. Having said that I inherited a few bags of mushroom compost last year which I put across a few of my beds which didn’t look fully rotted down but over the year this has settled and given a nice texture. A few mushrooms poked up here and there. Some of my potatoes did have a little scab on them but nothing major. If anything it’ll be good for feeding the soil overall and improving it

    Thanks for your reply Carrie. I might try a mixture of bought compost and the mushroom compost and see how that works.
