I planted a few asparagus crowns 2 years ago. Their first year they put up a few shoots, then last year they went like gangbusters and I had a beautiful asparagus frond forest. I held off on harvesting any spears, though.
There are spears starting to poke up from the ground now, and I recall that the growing instructions said that it's okay to harvest "lightly" for 2 weeks in the third year. Does lightly mean, take only a few spears from each crown for the two weeks? Or can I harvest everything for two weeks and then stop & let the spears grow up into fronds for the rest of the growing season?
