The potatoes, onions, etc. will spend the whole season growing to harvestable size before we start eating them, but the beets, carrots, kohlrabi, etc. we grow in rounds, if you you will: plant or seed now, grow to harvestable size, and harvest the whole thing. A couple weeks after we see the first round, we start another. This way we always have the item during the season. A succession.
These late spring/early summer weeks set the stage for our whole summer CSA. It will be a few weeks yet before you start to get things out of the 25-acre, but in about a month, the tide will change, and the 25 will begin supplying the majority of our vegetables.
