Installing a drip irrigation system on an automatic timer is one of the most effective ways to improve your garden’s productivity, while saving you time and money. Drip irrigation is a system of narrow plastic tubes that deliver water at a slow rate directly to the surface of the soil. Since the water is emitted slowly, it has time to soak into the soil, rather than run off or through the soil. A properly installed and monitored drip system will deliver just the right amount of water with very little waste.
