To ensure proper drainage and prevent root rot, it's important to add a layer of materials at the bottom of your planters. Here are some effective options:
Gravel or Small Rocks: These help with drainage by allowing excess water to flow through easily.
Broken Pottery or Tiles: Recycled shards can serve the same purpose as gravel.
Charcoal: Activated charcoal can help absorb impurities and odors if you are planting indoors.
