Hello All! I just picked up 24 bulbs of asparagus. 8 are purple and the rest are NJ hybrid. We are avid asparagus eaters. I was looking for some tips on planting them. I plan on having them in row planters that are moveable. The bulbs seem dry. It says they are "2 year old" roots on the front fo the package but on the back it says "these roots are the size of 2 year old roots"... So is this really a 2 year old root? It was all that was available.
