Absolutely! Growing leafy greens like lettuce and spinach in urban planter boxes is not only possible but highly rewarding. These fast-growing crops are perfectly suited for container life. The key to success lies in a few simple steps. First, choose deep planter boxes (at least 6-8 inches) with excellent drainage. Use a high-quality potting mix, not garden soil. Position your boxes where they receive at least 4-6 hours of sunlight daily; morning sun with afternoon shade is ideal for preventing lettuce from bolting in heat. Sow seeds directly or transplant seedlings, keeping spinach plants about 3 inches apart and lettuce 6-8 inches apart. Consistent watering is crucial—keep the soil evenly moist but never soggy. A light application of organic, balanced fertilizer every few weeks will support lush growth. For a continuous harvest, practice "cut-and-come-again" by snipping outer leaves, allowing the center to keep producing. With minimal space and care, you can enjoy fresh, homegrown salads right from your balcony, patio, or windowsill.
