Actually, Lesa you can't harvest any for the first year, then only about 1/2 the second year, then all you want after that. Basically the way I see it this year which is our second year we're getting about 50% of our spears that are eating size. That is they are the size you'd find in a market or maybe the diameter of a man's pinkie finger. The other 50% are thinner and should not be cut but rather let the plant go and it will fern out. These are about the diameter of a pencil. Just let 'em go to head because there'll be plenty more coming up. We have ours in a 4'x8'x12" raised bed box and I believe Teresa planted 2 bunches in it, which I thought was too much at the time. They were spaced out about one foot apart in the bed. Last year a bunch came up and we just ignored them. But for the past 2 weeks or so we've been getting 8 to 10 edible spears a day. Some of them make it in the house and end up in omelets or as a side dish. Some of them... They taste like candy when they're first cut right out of the box!
