Hi gardeners, my DD has decided that carrots is what we are planting in the veg patch this year. I have read on the packet that the soil needs to be fine and stone free and not recently manured..... I'll have to get the sieve out, and am planning to put in some well rotted leaf mould....is that any better than manure though? I am grateful for any input on mulch/ any other carrot tips. ta.
