Cleansweep, thankyou for taking the time to answer. Neither leek or chive I’m afraid, they were newly created no dig beds last year and were planted with beetroot, sweet corn and courgettes, no leeks or chives were in the vicinity.
Re the fungus I was worried that I may not be able to plant this year because of it – I am very new to gardening and unsure of what’s ok and what’s not.
