perhaps this has already been answered but I can't see the wood for the trees.
I have just planted 7 one year old crowns, and intend to sow seed to produce more crowns to plant next year.
My question is, just how many crowns do I need to feed a family of 4? I will presume that the spears can be frozen (?) and I have a daughter who is appreciative of most of the vegetables that appear on her plate. I am envisaging extending the existing plan of 7 crowns to 18 crowns, ie adding another 11, but is this a realistic quantity, having never harvested asparagus before.
