URBAN PLANTER BOXES

For a total newbie, the easiest vegetable to grow in an urban planter box is loose-leaf lettuce. It is fast, forgiving, and does not need deep soil. A planter box that is about 6 to 8 inches deep with drainage holes is enough. Fill it with light potting mix, sow lettuce seeds thinly on the surface, and cover them with a very thin layer of soil. Keep the mix evenly moist—not soggy—and place the box where it gets morning sun or about 4 to 6 hours of gentle light. In warm weather, a little afternoon shade helps prevent bolting. Seeds usually sprout in 7 to 14 days, and you can start picking outer leaves in about four to six weeks. Instead of pulling the whole plant, harvest a few leaves at a time so it keeps growing. Loose-leaf lettuce is much easier than tomatoes, peppers, or cucumbers because it has shallow roots, grows quickly, and has fewer demanding requirements. Just check the soil with your finger before watering, keep the box on a balcony or near a sunny window, and you will have a beginner-friendly crop that rewards you quickly.
