Watering your lawn in the morning is a great way to halt the development of fungus. By watering your grass in the morning, you give it a chance to absorb the moisture, while allowing the heat of the day to burn off any excess moisture left behind. If your lawn is left to sit wet for long periods of time, fungus and mold can grow, leading to much larger problems down the road. If you feel that your lawn already has a mold or fungus infestation, you may want to consider having a Charlotte irrigation specialist come over to inspect the problem.
Be mindful of how much water your lawn is receiving. Ideally, you should be giving your lawn about 1 inch of water weekly. You may want to install a wind or rain sensor in order to keep up with how much water your lawn is receiving naturally, so you don't over water. You should also have a Charlotte irrigation specialist come out and inspect your irrigation system for leaks in heads and other elements of your irrigation system.
Finally, you will want to separate your sod areas from the rest of your zones. This can maximize efficiency in your watering process, as sod and shrub beds need different levels of care. Grass that has rooted itself can be easier to treat, but unrooted grass can be a bit fickle.
