If you have some big bucks to spare for a beautiful green lawn, my first choice would be an ancient Roman slave in a toga, but my second choice would be the sprinkler. However be forewarned. Sprinklers are not simple, and if badly installed or poorly designed they will become a permanent maintenance pain. Let’s begin with the options:
Surface Drip Systems though short-lived, are cheapest and easiest to install. They’re most useful for shrub beds, vegetables and flower borders.
- The easiest is a soaker hose, which is just that, a hose that leaks on purpose all along its length. You turn it on, and when you think it’s enough, you turn it off.. Problems are that it’s hard to calibrate and it becomes brittle after cold weather.
Underground Sprinklers are what most people are familiar with, especially for the lawn.
- Yearly maintenance costs include re-adjusting the sprinkler heads, and trouble-shooting. In cold climates, the system has to be blown out with compressed air so the pipes will not freeze and burst, and then turned on again in spring. Water is an additional cost. Water costs can be much higher if a sewer charge, based on water use, is added, so many towns allow sprinkler systems to have a separate meter. Some people drill wells which produce water of adequate quality for plants but not for human use.
Problems are that all sprinklers have to be blown out with compressed air before winter in cold climates, and breaks have to be mended (with connectors) as needed.
Ask Lots Of Questions - There are some things to check out before you sign on the dotted line. Most important is the design. It involves an analysis of your water pressure, picking the right components, keeping beds and lawn zones separate, and providing zone to zone coverage but without wasting water. Experienced installers can do it quickly, but ask to have it explained to you.
Check The Quality Of The Parts - Make sure that quality irrigation parts are used in the irrigation system installation. You can check the rating of various irrigation system manufactur online. Also, how long is the guarantee period? Cold winters are hard on sprinklers.
Ask About The Controller - A good one should be able to set different zones for different schedules per week. There must be a manual override so you can turn parts off and on when you wish. And there should be a rain sensor to turn it off when it rains and so conserve water.
How Much Water, How Often, And On What? - Don’t let your sprinkler company set your timer by their mantra universal setting. Short, frequent waterings encourage shallow rooting, diseases and low tolerance to stress, like drought and heat.
Here are some basic irrigation amount guidelines:
- Grass: About 20 minutes per zone, three times a week (This should be about l” of water. To check, put out a glass and measure the depth. The soil should be wet about 6 to 8 inches down. Use this also for newly planted trees and shrubs.
- Flower beds: 20 minutes every other day.
- Old shrubs and trees: only need water when it doesn’t rain.
How Can You Tell When The Grass Needs Water? - When walked on, the footprints remain visible for several minutes. When the grass blades don’t spring back, it means wilting is imminent so manually turn on the water long enough to supply a full inch.
The Best Time Of Day To Water is very early morning. Then the grass will be hydrated during the heat of day, and the individual grass blades will have time to dry off and not get fungus diseases.
The Biggest Problem with all underground sprinklers is if they are not installed deep enough, they can be punctured with an edger or a lawn aerator. Also, frost heaves can push pipes to the surface which may trip someone or be damaged by the mower. The recommended depth for irrigation systems is 12 inches.
