Some crops are harvested early, like peas and salad greens, which means you might have empty spaces in your garden mid-season.
What now? You can re-plant in that spot for a second harvest!
Beans are quick to mature and are an ideal choice. You can also put in cold weather and frost tolerant plants like cabbage, broccoli and cauliflower, as well as kale, which you'll be able to harvest into October.
