July Newsletter: Irrigation & Lawn Care


We are in the heart of the rainy season so now is a great time to save water! Put your irrigation on manual and operate it only when needed. Invest in a rain gauge (or a tin can will do)! If it does not rain during the week- up to one inch- then turn on your system to water. If you don’t have a Rain Sensor, get one installed and have your system checked periodically to insure even coverage and no broken heads.

Mature plants, palms, grass and shrubs only need ¾ of an inch to 1 inch of water per week.

Overwatering causes big problems! Check your irrigation output to determine how much water your system puts out by putting some tin cans out and run the system through. Measure how much you put out every time you run the irrigation. Turn time up or back to make sure you only are putting down an inch per week.


Watch for lawn pests during the summer months. Chinch bug damage in St Augustine grass occurs as straw colored patches in the sunnier, hot parts of your lawn- in particular, near walkways and driveways. Apply products labeled for Chinch Bugs. Try rotating products to prevent chinch bugs from building up a resistance to a single product. Some examples would be Hi-Yield Bug Blaster, Hi Yield Grub Free Zone III, and Bayer Complete.

Seeing Bevies of Moths Flying in Your Landscape?

The moths you are seeing will not cause damage; however, they are depositing eggs which will result in the offspring, the caterpillars, chewing on the turf- Tropical Sod Webworms. Some of the telltale signs are areas of your grass that looks lower- like someone took a weed-eater to it. Lighter color patches in your grass. Turf can recover from tropical sod worm damage if properly irrigated and kept healthy. Drought or low mowing heights may prolong or prevent recovery. Chemical control should be directed at the feeding larvae and not the flying moths. Spot treat the areas where infestations are detected. Insecticide is best applied in the early evening when the larvae feed and apply two weeks after you see peak moth activity. Use Bayer Advanced Complete Insect Killer or Spinosad Insect Killer–as two possibilities. As always, if you have questions- stop in for advice.

If sedgegrass or dollar weed are a problem check your irrigation or soil. These weeds are generally associated with high soil moisture and high PH for sedge. If there are too many to pull, try Image for most of the sedges and Dollar Weed Control for the dollar weed.
