One of the best ways to address the challenge of drought restrictions or our normal summer heat is to make use of leaky hoses. During drought restrictions, leaky hoses qualify as drip irrigation which means their use is unrestricted during “Stages One and Two.” Leaky hoses are inexpensive and versatile, string them out where you need them, and then move them to another site if the need is greater. Leaky hoses are very efficient. Just like drip irrigation, they put the water where it is needed without much evaporation and no wind interference.
I have heard one of my horticultural colleagues say that leaky hoses clog up quickly. I have not had the same experience. My hoses after five years of use are more likely to be ruined by careless lawn mower driving then by clogging. At less than $10 a purchase, even three-four years of use is a good investment.
Use your leaky hose to water newly planted trees and shrubs. Run the hose along the rows of flowers and vegetables for an efficient irrigation system. Leaky hoses are especially effective to use to provide supplemental water for hot spots in the lawn. It is not unusual for lawns to have a strip along the driveway or curb where it never seems to receive enough water. Rather than apply excess water to the whole lawn, give the hot spots a weekly supplemental dose of leaky hose irrigation. Stretch it out, run the water for an hour or more, and it will green up the trouble spot.
Running the soaker use for an hour or more may sound like it would use lots of water, but it is not so. If the faucet is turned ¼ to ½ turn it “sweats” the water out at the right rate without danger of runoff.
I like the recycled leaky hoses, but the same water efficiencies can be achieved by using a green soaker hose turned over so the water is applied directly to the ground.
