What Happens if I Don’t Water My Lawn?

Category: Lawn Care

Down south, if you don’t water, you don’t have a lawn, you have dirt, sand, and weeds. It also seems that near larger urban areas, there also seems to be more people with irrigation installed on their properties, especially smaller properties. However, here in the Lancaster, PA area, it’s actually pretty uncommon for people to have irrigation systems, particularly when they have a larger lawn. This isn’t because they aren’t needed. The common view of irrigation systems in our area is different for a number of factors.

Grass blades turn brown as they lose available moisture. If the drought doesn’t last much longer than 3-4 weeks, most of these areas can re-grow new green blades when wet conditions return. However, if lawns don’t get 2″ of water each week for longer than 4 weeks, permanent damage can occur to grass plants. Root systems can be damaged to the point where grass blades will not only stay brown, but these areas will be thin or completely dead. Combine that with a turf disease problem or insect damage, and you will need to have lawn seeding in the fall, starting from scratch.

In fact, 2-3 deep watering sessions per week are much better than short watering each day. This will keep soil moist deeper, causing grass roots to grow deeper into the soil. If spring brings abundant rainfall, irrigation won’t need to be used until sometime late in spring or early summer, throughout the summer, and then can be turned off in the fall. The point is just to keep the lawn alive throughout the summer.

Economics of Watering Lawns:  It’s not all or nothing. If you have the money to have professional lawn sprinkler system installation go for it, but if you can’t afford this, there are other options that can make a big difference. Most home and garden stores will sell a variety of sprinklers, each with its own purpose for the space they are watering. Likewise, you can purchase hose splitters and timers and set up temporary irrigation systems for your lawn that can divert water pressure to each area as a zone before it goes to another. It’s possible to set up a temporary system to water the front lawn one early morning, then the back lawn the following day. That’s a much better method than dragging hoses and sprinklers around and being chained to your property all day throughout the week.

If you’re considering having an irrigation company install professional sprinkler systems for either your lawn or landscaping, you don’t even have to install a system on your entire property, you could just keep the front lawn looking great for curb appeal. If you decide that watering your lawn isn’t a task you’d like to tackle and a professional irrigation system is right for you, we’d love to talk to you about designing and installing irrigation on your property.
