12x12' of asparagus. That's a lot of asparagus! You are correct in the harvest timing. You want the asparagus spears/leaves to channel all the energy possible to the root system during the first two years. Depending on the size of the planting, you'll begin to harvest that third year, but only take the ones that are between a pencil thickness and the thickness of your little finger. Leave the small ones alone, letting them grow to leaf and thus returning energy back into the root system. Each year after, you will have a larger patch and the harvestable spears will get larger.
