Lawn Fertilization and Treatment questions, answered by experts

The best fertilizer for early spring is an organic slow-release fertilizer that sets up your lawn for continued good health and vigorous growth throughout the whole growing season. If your lawn is particularly neglected or has specific issues, you may need an application of quick-release fertilizer alongside a slow-release one for an immediate boost. 

You can fertilize right after mowing as long as you've collected the clippings. If you leave grass clipping, they can form a mat that prevents the fertilizer from reaching the soil. Plus, grass clippings are rich in nitrogen, so if you leave them and then apply fertilizer, you can end up with too much nitrogen in the soil.

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.

Professionals employ protective measures such as covering or temporarily relocating plants, minimizing chemical usage, and carefully planning construction routes to avoid damage. These precautions preserve the integrity and appearance of the landscaping during projects.

The best time to top dress your lawn depends on what type of grass you have and what climate you live in. Cool-season grass should be top dressed in late fall, while warm-season grass should be top dressed in late spring.
