The USDA Zone info is a great tool for gardeners to help us figure out your gardening schedule. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

The first opportunity to plant celosia in Monterey should be figured out by using the USDA zone info.

You really shouldn't plant celosia until after the last frost when the weather gets warmer because they do not do well in cold weather.

The earliest that you can plant celosia in Monterey is February. However, you really should wait until March if you don't want to take any chances.

The last month that you can plant celosia and expect a good harvest is probably September. Any later than that and your celosia may not have a chance to fully mature. Starting your celosia indoors is a great way to get them started a few weeks earlier.
