I bought some wild asparagus crowns from 'Seeds of Italy' which arrived in a parcel on 23rd Dec! I was advised that if I stored them in some damp (but not wet) sand in a cool place, they would be ok for up to 4 months. Although I haven't dug down to check on all of them, some of them have already started growing, so I'm hoping that they are all ok. As I'm trying Biodynamics this year, I don't plan to plant them until the 24th March, which is apparently supposed to be a suitable day (I missed the last one that fell on a weekend!)
