How to deal with brown spots
In the heat of July, almost every lawn has brown spots and we all see them. Brown spots are really the lawn’s S-O-S call for help. The grass is obviously stressed and of course, we think it needs MORE water.
We’re tempted to turn up the sprinkler system so it waters longer. But watering longer won’t solve the problem if the water isn’t getting to that brown spot to begin with.
So, how do we find the problem?
Many brown spots can be solved right at the source of where the water comes out – at the sprinkler heads themselves. Four common problems are quick fixes that can get much of your system back in order. If you do the work yourself, it shouldn’t take a lot of time. Whether it’s a DIY project or you bring in the Signature Landscapes technician, the benefits will be a healthier lawn and hopefully, less water use and costs.
4 Causes of brown spots
- The nozzle – the part in the sprinkler head where the water comes out – is clogged. Dirt and debris often get into the nozzle and once it is cleaned out, the head will spray water where it’s intended.
- The direction of the nozzle’s spray is out of adjustment. The nozzle may be directing water too low or too high. Either one will keep the water from hitting the area it is supposed to reach. Making the adjustment will solve the problem.
- Rotor heads – the ones that oscillate back and forth – may be pointed in the wrong direction or stuck. A head that’s aimed at the street rather than your lawn is the culprit for the brown spot and wasting water in the process. Getting the head back into adjustment will put the water where it needs to go.
- Sprinkler heads aren’t popping up high enough. Equipment damage or soil build-up over the years may mean the sprinklers are no longer popping up high enough to clear the top of the grass blades. Water will hit the grass closest the head and be deflected. Raising the heads – or replacing them with sprinklers that pop up higher – will solve the problem.
More advice for brown spots
For a few days if temps remain high, you may want to hand water just those brown spots to give them extra TLC – but avoid making the entire sprinkler system run longer just to deal with problem areas. That’s a waste of water – and added cost.
