There is a plantation where the asparagus grow wild. So far there have been three harvests. Each stalk is evaluated for harvest, now or later. Now means this is what you get. There is nothing else to be expected. The question is can I use it all before the next harvest? Later means, letting it get taller, fatter, and either getting more asparagus goodness or less asparagus goodness if it gets woody. Later is risky – poachers.
