I applied Scott’s 3-1 in February. Is it okay to apply this pre emergent to my yard as well?

Scott’s 3-1 Fertilizer (applied in February) is typically a fertilizer with some pre-emergent or weed control mixed in, depending on the exact product. The Sunniland 50-lb Pre-Emergent Crabgrass Control is a dedicated pre-emergent herbicide designed to prevent crabgrass and other grassy weeds. Can you apply Sunniland after Scott’s 3-1? Yes, but with caution. Applying two pre-emergent products close together can increase the risk of over-application, which might stress your lawn. Check the active ingredients in Scott’s 3-1 first. If it already contains a pre-emergent herbicide (like dithiopyr, prodiamine, or pendimethalin), wait until the effectiveness of that product diminishes—usually about 6-8 weeks after application—before applying another pre-emergent. Since you applied Scott’s in February, if it’s now late spring or early summer, you might be okay to apply Sunniland, but double-check timing and label recommendations to avoid lawn damage. Best advice: Read both product labels carefully to ensure you’re not doubling up on pre-emergents too closely. If unsure, wait at least 6-8 weeks between pre-emergent applications. Or, consider applying the Sunniland next pre-emergent season instead.
