Terry,
I left the spears from one plant because they were pretty skinny. Figured it could use some growth. I had to replant half my bed this year because half the crowns I put in last year were a poor choice and didn't come up. Not knowing what they should look like, I bought some boxed crowns at a hardware store which already had ferns. Then I bought some more really good crowns at a local plant store....bare roots, but nice and fleshy. The latter all came up and that's what I'm harvesting this year. When I started doing the bed last year I was all ready to do it the old-fashioned way. Dig a deep trench, put in mulch, put in the crowns a foot deep, gradually fill in around the developing ferns. Then I did a search on the web and found a university horticulture page which basically said, "dig a 6" trench, throw in some super phosphate, throw in the crowns, and bury them." I like simple! Plus it said I could harvest lightly the following year rather than wait another year. From the growth I'm getting this year, it appears simple works fine.
Bird, are those your blackberries in the picture? I don't think I'll get enough asparagus for pickling this year....maybe next. I'm about to put the okra in however, so I'll get to pickle something anyway!
