For best results, we recommend mowing your grass once a week.
There are four reasons for this:
1) The grass has two portions: the top which is flat, and the bottom which is a tube-shaped design to hold moisture and nutrients. If you cut every two weeks, you give the grass enough time to grow past the flat portion, now exposing the tube area to the blade of the mower. When the tube is cut, you have a greater chance of having your grass look dry... especially if there is a hot day following the mowing.
2) When you mow each week, you can mulch your clippings over your grass, which is a natural way to fertilize it. Your clippings hold nutrients and seeds which will help its growth and health. It will also help form a barrier against the sun and thus keep moisture in the ground.
3) The mower blade will turn faster, with little resistance, allowing to mow with a cleaner cut. If the blade is slowed down by the thickness of the grass, the cut is not as clean and will have some tear which, in time, will hurt its health.
4) It will be a lot easier to cut your grass and make it look nice, with no clippings visible because they are small enough to fall in between your grass. It's also easier on the mower.
Watering your lawn
It is recommended, for better result, to water your lawn every two days for about 15 to 20 minutes per zone.
Also important is to water after sunset. That will allow the water to stay in the ground longer and to not evaporate right away.
Also, if you water your grass during the day, you risk burning your grass.
We also recommend to fertilize your lawn with a weed-and-feed fertilizer for two reasons. It will help against weeds and grass, and will provide nutrients for your grass. Every two months is a good pattern.
Fertilizing your grass too often could result in having a weak root system, or possibly burning it. Not enough and you will have weeds in your grass.
