Proper drainage is crucial for healthy plants in urban planter boxes. If your plastic containers lack adequate drainage, adding extra holes is a simple DIY solution. Begin by emptying the planter completely and cleaning its surface. Select a drill bit specifically designed for plastic - a 1/4 to 1/2 inch twist bit works well. Mark your drilling locations on the bottom surface, spacing them 4-6 inches apart. Place the planter on a stable surface with a scrap wood block underneath to support the plastic. Drill at low to medium speed, applying gentle pressure to prevent cracking. Avoid forcing the drill through the plastic. Once completed, smooth any rough edges with sandpaper. For existing planters with plants, consider temporary relocation during this process. This simple maintenance task significantly improves drainage, preventing root rot and promoting healthier plant growth in your urban garden. Always wear safety glasses during the drilling process and test drainage with water before replanting.
