It is best to water your lawn every other day for 20 to 45 minutes per zone. Customize as needed giving sunny/dry areas more and shady/wet areas less. Shrub zones 15-30 minutes per zone. (Based on the type of system you have).
Do not water your lawn daily at only 10-15 minutes per zone. This will create surface rooting, disease and an unhealthy lawn.
Water deep and infrequent to develop a deep root system and stronger lawn. Typically every other day in the summer. If the lawn still requires more water in the heat of the summer increase the zone times to 45min or more per zone. Or add additional water by manually running the system an extra day during a heat wave.
The best time to water is between 4am and 9am.
Start your system one day per week around mid to late May. Then increase based on weather conditions.
During the summer a total of 1 ½” of water per week is best. You can place a bowl in your lawn to determine the amount of water your system is putting out.
Cut back watering days going into late-September and stop watering around mid-October.
Seeding will require different watering techniques or it will fail. Generally daily watering at only 20 minutes per zone. After about 10 days, water ½ hour per zone. After 30 days reduce the watering days to every other day.
Disease can occur and cause damage at any time of the year and will increase or decrease based on weather conditions. The best defense to help prevent lawn diseases are:
Understand your system so you can adjust setting throughout the year as needed. Consult with your irrigation technician as needed. Have all zones labeled at the timer.
Make sure all heads are working correctly. Grass will grow over your heads causing them to work poorly. Grass must be cut away from heads every few years.
Water sensors should be cleaned and working properly. Get one installed if you don’t have one. The sensor will shut your system off during wet weather. Many properties have malfunctioning sensors, causing damage to lawn and wasted water expense
Try not to water on your mowing day. Water a day or two after is best.
Run system from approximately 3AM to 7AM. Earlier and later with a larger system. To help prevent disease, never start system during p.m. hours.
Mowing your lawn correctly is a very important part of maintaining a healthy attractive lawn.
Make sure your mower blade is sharp! A dull blade will tear the grass instead of cutting it. Then the tips of the grass may turn gray/brown giving your lawn a bad appearance and leaving it more susceptible to insects and disease.
Try to mow when the grass is dry.
Remove approximately 1/3 of the grass per mowing.
Keep your lawn mowed height 2.5 to 3.5 inches. This will improve root development, help crowd out weeds, and give you an overall healthier and greener lawn.
Thatch is a layer of partially decomposed grass blades, stems and roots. It occurs naturally but increases rapidly when using low quality fertilizer products. A small amount of thatch is beneficial, however, when the thatch layer exceeds ½” it can cause lots of problems. The thatch barrier will prevent water, air and fertilizer from reaching the roots properly. Insects and disease will make home in the thatch, and then cause Damage and will be difficult to control.
De-thatching/power raking or core aeration should be done every few years to combat this problem and leave you with a healthier lawn. Your lawn will then require less water and have fewer problems with insects and disease. Late summer and early fall is the best time for de-thatching and it is often combined with over seeding.
Contrary to what most people think, leaving the grass clippings on your lawn is very beneficial. The clippings add valuable nutrients and needed organic matter to your lawn. Studies have found that after one full year of mowing and leaving the clippings on the lawn it contributed to less than 1/16” of thatch buildup. If you feel the clippings are a nuisance consider recycling bi-weekly or at least once a month.
1-888 Lawn Tec recommends recycling grass clippings at least once a month and after each of our service applications. However, weekly grass recycling is best and is now recommended by any lawn care expert.
