Can anyone advise me, I have been given 10 bags of old used mushroom compost , can i use this spread directly as mulch on / around plants ?, are there any plants /trees i canot use it on.
I have been told i cannot use for rasberries, is this correct?
Can i use it in my runner bean trench ?
please advise me a s p, thanks.
You can use it on most things apart from acid-loving plants as it contains quite a lot of lime. It doesn't have much in the way of nutrients left though, so best used as a soil conditioner or as a surface mulch.
It's good as a soil improver or mulch on most veg, but especially brassicas. Raspberries prefer more acidic soil so no it's not good on those or other fruit. I wouldn't use it in the runner bean trench unless you're mixing it with compost which will provide the nutrients
