Question
When do you usally seed and fertilize a lawn in California,90310

Answer
In Los Angeles you want to sow grass in late spring as the soil warms up. Try to target 2-3 months prior to the hottest time of the year. This applies to seeds for grass types such as bermuda, centipede, and zoysia. If you go for tall fescue, it is better to sow this in fall, after the daytime high temperatures fall consistently below 85 F. This would be October/November.

Warm season grass should be fertilized during the summer and early fall, but not too early in spring (not before March). Cool season lawns (tall fescue) should only be fertilized in fall, after daytime temperatures have cool significantly. In any event, avoid fertilizing too heavy in August for both types.
