Lawn Fertilizer Schedule FAQ

Question 1

When is the best time to fertilize my lawn?

Accepted Answer

The best time depends on your grass type. Cool-season grasses (Kentucky Bluegrass, Fescue, Ryegrass) should be fertilized in early fall (September) and late spring (May). Warm-season grasses (Bermuda, Zoysia, St. Augustine) grow best when fertilized in late spring through summer (May-August). Our generator creates a custom schedule for your specific grass and zone.

Question 2

How often should I fertilize my lawn?

Accepted Answer

Most lawns benefit from 4-6 fertilizer applications per year. Cool-season lawns typically need fertilizing in early spring, late spring, early fall, and late fall. Warm-season lawns are fertilized monthly during the active growing season (May-September). Avoid fertilizing during dormancy or extreme heat.

Question 3

What type of fertilizer should I use?

Accepted Answer

Use a balanced fertilizer (like 10-10-10) for general maintenance. In spring, use higher nitrogen (first number) for green growth. In fall, use higher potassium (third number) for root development and winter hardiness. Slow-release fertilizers are best for steady feeding without burn risk. Always follow package rates.

Question 4

When should I aerate my lawn?

Accepted Answer

Aerate during your grass's peak growing season. For cool-season grasses, aerate in early fall (September-October) or spring (March-April). For warm-season grasses, aerate in late spring to early summer (May-June). Aerate when soil is moist but not wet, and avoid aerating during drought or dormancy.

Question 5

When is the best time to overseed my lawn?

Accepted Answer

For cool-season grasses, overseed in early fall (late August to mid-September) when soil is warm but air is cooling—ideal germination conditions. For warm-season grasses, overseed in late spring (May-June). Always overseed after aeration for best seed-to-soil contact. Water frequently until established.

Question 6

What is my lawn's climate zone?

Accepted Answer

The US is divided into cool-season, warm-season, and transition zones. Cool-season zones are in the northern states where winters are cold. Warm-season zones are in the South where summers are hot. The transition zone runs through the middle of the country where both grass types can struggle. Our generator uses your location to determine your zone.
