Watering your plants and flowers during the growing season can be a tiring job, but it doesn't have to be. Drip irrigation is a great way to keep your gardens looking beautiful while conserving water. Drip irrigation works by slowly delivering water directly to plants' roots so you can water less and not as often. By maintaining an ideal moisture level, less water is lost to sun or wind. Drip irrigation is 90% efficient compared to sprinkler systems which are 50% to 70% efficient. Drip irrigation is simple to install. It consists of polyethylene tubing, runs all through your garden and lies right on the ground. The tubing has several small holes and this is where the water drips out. Some systems will have what are called drippers or emitters. They look like small sprinkler heads. How many holes or emitters you need will depend on the size of the plants. As a general rule, install at least 2 emitters for each plant and space them 18 inches apart. Watering times depend on the type of plant. For vegetables and flowers, water 30 minutes to an hour 2 to 3 times a week. For small trees and shrubs, water 1 to 2 hours 3 times a week. With the drip irrigation system, you don't have to spend your entire summer watering.
