Common Mistakes to Avoid

While it’s essential to know how to improve soil drainage, it’s equally important to avoid common pitfalls that can compromise your efforts. Here are some mistakes to steer clear of:

  • Neglecting Drainage Holes: Ensure your pots have sufficient drainage holes to allow excess water to escape. Without proper drainage, water can accumulate at the bottom and cause root rot.
  • Ignoring Plant Needs: Different plants have different moisture requirements. Be sure to select soil and watering practices that align with your plant’s specific needs to avoid overwatering or underwatering.

By avoiding these common mistakes, you can maintain healthy soil conditions and prevent issues related to poor drainage.
