My plot neighbour has moved plot after 10 years to one adjoining his second plot (free 5 metre polytunnel thrown in and 2 sheds). He has given me 20 asparagus crowns - he took the rest with him. I know NOTHING about growing asparagus, and just planted them in with plenty of muck in the soil (default method when I'm not sure what to do) and top dressed with fbb. Some are starting to show, but do they need feeding? Would they benefit from magnesium sulphate?
