If you've noticed soil washing out of your planter box drainage holes, you're not alone. This common urban gardening issue can be frustrating, but several simple solutions can help. Start by placing a layer of landscape fabric or coffee filters over the drainage holes before adding soil. These materials allow water to drain while keeping soil particles contained. Another effective method is creating a drainage layer using gravel, pebbles, or broken pottery shards at the bottom of your planter. This layer acts as a barrier, preventing soil from reaching the drainage holes directly while improving water flow. For optimal results, consider using a potting mix containing coconut coir or vermiculite, as these materials help bind soil particles together. When watering your plants, do so gently and slowly to minimize soil disturbance. If soil continues to wash out, reduce watering intensity or frequency. Regular maintenance like topping up soil and checking drainage holes will keep your urban garden thriving while preventing messy soil loss.
