I've used mushroom compost as a mulch on a brassica bed on the allotment. I'm given to understand lime is added to the compost to stop mushrooms growing so it seemed like a good plan to use as a mulch to stop weeds from growing and ideal for brassica's.
The red cabbage has bolted but me thinks it was due to it being planted to early plus the soil may have been to rich in lime. I've now dug in the compost and plan to grow brussels and kale in the bed...to cut to the chase there is a problem with nightmares tail on my plot.
I didn't want to start another nightmares tail thread but a poster had advised nightmares tail doesn't grow well in limed soil and I've found it hasn't grown at all in that bed.
Has anyone else found nightmares tail alias horse or mares tail doesn't grow in limed soil?
