Seeding and Fertilizing Calendar for Los Angeles Lawns: Warm vs. Cool Season Grasses

Los Angeles (90310) supports both warm- and cool-season grasses. Timing differs sharply.

Warm-Season Grasses (Bermuda, Centipede, Zoysia)

• Seeding: Late spring as soil warms—target 2–3 months before peak heat.
• Fertilizing: Summer and early fall. Not before March. Avoid heavy August feeding.

Cool-Season Grasses (Tall Fescue)

• Seeding: Fall, after daytime highs consistently below 85°F (October/November).
• Fertilizing: Fall only, after temperatures cool significantly.

General Rule

Never fertilize heavily in August for either type. Match grass to your microclimate and maintenance preference.
