This irrigation system delivers a gentle flow of water to the roots of your plants. Water conserving and easy to install. All you need is a garden hose! We recommend 3 to 5 gallons of water each week during the growing & blooming season. The amount of time to run your Shur Flo System depends on the number of Shur Flos installed, the length of your garden hose, and the water pressure at your house. We have found it best to water your roses 2 to 3 times a week rather than a little bit every day. Keep a rain gauge in your garden to track rainfall and conserve water.
