Rainwater harvesting is a simple and effective way to conserve water and reduce your environmental footprint. By installing a rainwater collection system, you can collect rainwater from your roof and store it for use in your garden. This can significantly reduce your water bill and ensure that your plants are well-watered even during dry spells. A rainwater system can be as simple as a barrel or as advanced as an underground tank, depending on the size of your garden and your needs. Incorporating this sustainable practice into your landscape will help you create a water-efficient garden.
