Post-Emergent - Lawn Fertilizers - The Home Depot

Question 1

How often should I fertilize my lawn?

Accepted Answer

The right application frequency depends on your type of grass, soil health, and choice of fertilizer. Fertilize cool-season lawns like Kentucky bluegrass, fescue, and ryegrass two to four times a year, in early and late spring and fall. Fertilize warm-season grasses like Bermuda, Zoysia, and St. Augustine three to five times per year, in late spring, mid and late summer, and early fall. Apply slow-release fertilizers once every eight to ten weeks, and quick-release fertilizers once every four to six weeks.

Question 2

How do I know which fertilizer my lawn needs?

Accepted Answer

Start with a soil test to identify nutrient deficiencies and pH levels. This extra step prevents over-fertilization and ensures you choose the right formula. Then choose a fertilizer that matches your grass type and season. Select a high nitrogen fertilizer for green-up, a starter fertilizer for new lawns, and a winterizing blend for fall protection. Cool-season grasses like Kentucky bluegrass and fescue need more nitrogen in spring and fall, while warm-season grasses like Bermuda and Zoysia need nitrogen during summer growth. Consider specialty blends for certain conditions like a weed and feed product, organic blend, or a pet and kid safe formula.

Question 3

When should I use an all-purpose lawn fertilizer versus a fertilizer designed to green my lawn quickly?

Accepted Answer

An all-purpose lawn fertilizer is perfect for general maintenance, giving your lawn a balanced blend of nutrients to support steady growth throughout the season. For a rapid improvement in color, select a quick greening fertilizer specifically formulated to deliver a fast boost of nitrogen. However, expect an all-purpose fertilizer to provide longer-lasting benefits.
