Creating a water reservoir in an outdoor plant box is a smart way to ensure your plants stay hydrated with minimal effort. Here’s a simple step-by-step guide to help you build one:

1. Choose the Right Planter: Select a sturdy outdoor plant box with drainage holes at the bottom. If it lacks holes, drill a few to prevent waterlogging.

2. Add a Reservoir Layer: Place a layer of gravel or small stones at the bottom of the box. This acts as the reservoir, allowing excess water to collect without saturating the soil.

3. Use a Barrier: Cover the gravel with a permeable landscape fabric or a thin layer of sand. This prevents soil from washing into the reservoir while letting water pass through.

4. Insert a Watering Tube (Optional): For easier refilling, insert a PVC pipe vertically into the gravel layer. This lets you pour water directly into the reservoir.

5. Fill with Soil: Add potting mix, leaving space for your plants. The soil will draw moisture from the reservoir as needed.

6. Plant and Water: Plant your greenery and water thoroughly. The reservoir will reduce watering frequency, making it ideal for busy gardeners.

By following these steps, you’ll create a self-sustaining system that keeps your plants healthy and thriving!
