Lawn Watering Infoline - September 6, 2017
Hello and welcome to the Lawn Watering Infoline. September is a great month to work on your lawn. Aerating, thatching, over seeding, fertilizing and applying a light layer of fine compost at this time of year will help to rejuvenate your lawn for next years’ summer usage. Be sure to check your sprinkler system operation before you get started.
Based on current weather conditions, turf grass needs just over one inch of water this week. Additionally, the weather forecast is calling for temperatures to be cooling over the next week, so monitor your lawn and adjust your sprinkling accordingly.
Different sprinklers apply water at different rates, but as an approximate guideline, you would need to run standard spray sprinklers a total of about 44 minutes for the week. Rotors apply water more slowly, so they need to run around 106 minutes over the course of the week to apply the same amount of water. If you have multi-stream rotators, you need to run those for 166 minutes for the week.
To determine how long to run sprinklers each watering day, divide the total minutes we’ve given by the number of days you will be sprinkling this week. For example, if you water 3 days per week, you would run spray sprinklers for 15 minutes each watering day to apply the needed amount of water. Typical rotors would need to run 35 minutes on each watering day and multi-stream rotators for 55 minutes each watering day.
Additionally, instead of applying all the water in one cycle, break up the watering into three shorter cycles separated by an hour or so. That would mean running spray sprinklers 5 minutes each cycle, rotor sprinklers for 12 minutes and multi-stream rotators 18 minutes. This will help the water absorb into our tight heavy clay soils.
To help you make the most of your watering, also consider the following tips:
Run your sprinklers before the sun comes out. If you complete watering before 6 a.m., your sprinklers won’t have to compete with other water uses, and can also take advantage of the lowest temperatures of the day. If you prefer evening sprinkling, wait until at least 9 p.m. when it has started to get cooler, and breezes have died down.
