Lawn Watering Infoline - May 15, 2019
Hello and welcome to the Lawn Watering Infoline. Today is Wednesday May 15th. In an effort to help save water, mention this Infoline to your friends and neighbors, especially if they are currently running their sprinkler system.
Based on current weather conditions, turf grass needs one and a third inches of water this week. Additionally, the weather forecast is calling for cooler temperatures with some rain over the next week, so monitor your lawn and adjust your watering 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 54 minutes for the week. Rotors apply water more slowly, so they need to run around 130 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 202 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 watering this week. For example, if you water 2 days per week, you would run spray sprinklers for 27 minutes each watering day to apply the needed amount of water. Typical rotors would need to run 65 minutes on each watering day and multi-stream rotators for 101 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 9 minutes each cycle, rotor sprinklers for 22 minutes and multi-stream rotators 34 minutes. This will help the water penetrate deeper into the soil.
To help you make the most of your watering this season, also consider the following tips:
May is a great time to fertilize a lawn. When you fertilize, it is always best to use a slow release fertilizer to feed turf grass. Apply enough fertilizer to give the lawn about one pound of actual nitrogen, the first number of the fertilizer formula on the fertilizer bag. If you need help understanding how much to apply, ask your local nursery or call us at 541.774.2435.
Run your sprinklers before the sun comes out. If you complete watering before 6 a.m., your irrigating won’t have to compete with other water uses, and also take advantage of the lowest temperatures of the day. If you prefer evening watering, wait until at least 9 p.m. when the temperature has started to get cooler, and breezes have died down.
