For some of us the wet season is almost over and for others it hasn’t begun. Yet for most of us it feels like planting time. Whether it planting out out the fruits of our seedling pots or starting from scratch, the question is, how are we going to keep our spring gardens watered when the weather isn’t playing along. Drip irrigation using harvested rainwater is a wonderful way to keep your garden growing. Gravity is your friend when watering using a tank. The higher your tank is above your irrigation system the greater the pressure. A slight slope in the ground will also help the water move.

As the name says, drip irrigation allows water to slowly drip onto the roots of plants either from the surface or from the soil beneath. This can save water by reducing evaporation and runoff. Have a look at these DIY drip irrigation projects and be inspired to try this in your garden.
