Wondering what to put at the bottom of your urban planter boxes for drainage? The right foundation is crucial for healthy plants. Start with a layer of coarse materials like gravel, pebbles, or broken pottery shards. This creates space for excess water to drain away from the roots, preventing rot. For best results, place a permeable landscape fabric over this drainage layer before adding your potting mix. The fabric keeps soil from washing down and clogging the drainage while allowing water to flow through. Avoid using non-porous materials like solid plastic, as they can trap water. For deeper boxes, consider adding a layer of lightweight filler like recycled plastic bottles or packing peanuts to save on soil while maintaining drainage. Remember, good drainage is the secret to thriving container gardens in any urban space.
