Getting the most out of irrigating

AgriLawn’s Seasonal Weed Control and Fertilization Blog

Now that the heat is on, the lawn becomes more dependent on water to maintain its growth and vigor. Coincidentally this happens at a time when beneficial rainfall generally occurs less often to help out. Without getting too much into the scientific happenings – how environmental factors such as temperature, wind, solar radiation, soil moisture and relative humidity affect plant transpiration processes like external boundary layer resistance, vapor pressure gradient and internal leaf diffusion resistance – it is safe to conclude that the lawn needs regularly irrigated this time of year to keep its desirable appeal. 

Having said that, to not be wasteful of our water, it is important to water properly and judiciously. Unfortunately, there really is no “one size fits all” approach to irrigating your lawn based on many factors; type of turfgrass, type of soil and soil conditions, environmental factors and type of irrigation equipment to name a few. So…what to do? Here are some tips to help you get the most out of irrigating.

  • Use a rain gauge – this tool measures the amount of rain/water received
  • Water deeply and infrequently (1 to 1-1/2 inches only once/twice per week)
  • Water in the early morning hours, not the heat of the day
  • Piggyback off of rain (if rainfall occurs a day or two within your normal watering day hold off watering until you know how much rain you received, then adjust your irrigation for the rest)
