Here we are in January, 2025. This is a crazy winter, but spring is coming fast. If you live in the south, NOW is the time to get started with a preemergent weed preventer. Usually they are good for 3 months, but if/when the weather suddenly turns warm and it rains, then you missed your opportunity. Apply now to cover through most of March, then apply again to get you through the rest of spring. I'm not talking about a weed n feed product. This is strictly for a preemergent. Fertilizing should not be done until May.
