It depends on the type of grass and the condition of your lawn. We advised you to fertilize your lawn at least twice per year. However, warm-season grasses and nutrient-deficient lawns may need to be fertilized up to four times a year. Remember, you don't want to over fertilize either, so soil testing can help to determine if your lawn lacks nutrients and if it’s ready for another application.

You should put pre-emergent herbicide and fertilizer on your lawn in the spring. Pre-emergent herbicide keeps weeds from taking root. Fertilizer helps your grass to grow lush and dense and blocks future weeds from growing. You can also add amendments, such as sulfur and lime, to enhance your soil quality. 

Yes, but the best approach is to apply fertilizer well before you actually sprinkle the seeds. Apply fertilizer with an NPK ratio somewhere around 10-10-20, or 10-10-10, depending on soil test results and the type of grass you're planting, about six to eight weeks before planting grass seed. This mix added to loosened soil will give the grass seed its best chance of getting off to a solid start. 

Yes, grass will regrow after forestry mulching, but the timeline depends on soil conditions, mulch thickness, and existing seed banks. The nutrient-rich mulch left behind helps retain moisture and improve soil health, encouraging regrowth. However, if the mulch layer is too thick, it may block sunlight and slow grass germination. For faster results, you can rake excess mulch, aerate the soil, and plant the new grass seeds.
