We are still very much in the time frame for fungus. Make sure you’re keeping an eye out for signs like yellowing or lime green colored grass. This could be a sign of a massive issue! We recommend being proactive and treating your lawn often during the heightened fungus season. This ranges any time from March sometimes into June in the spring season, and around October and November in the fall. Make sure you know how long the product you choose lasts. Some products only last for up to 14 days, while other products can last up to 30 days. In the active seasons, it is best to even overlap the treatments some to make sure there is always active product on the lawn to keep fungus at bay. That means that if your product lasts for 30 days, you can actually go ahead and retreat on day 25 or so. Hope this helps and if you have any questions, let us know!
