2. Kentucky Wonder Green Beans: If you have a three-tier GreenStalk or a shorter pot you’re using, that would work well for these because they will be growing high. You will need to use a traditional tomato cage, but you’ll use it upside down and tie the pokey ends together at the top. Only put two seeds where you want the plant to grow an inch below the soil. Use a low-nitrogen fertilizer sparingly. Once the beans begin to sprout, pick them every 3-5 days. They are ready to eat before strings appear, or you can wait until they’re mature.
