Planting Calendar for Celosia

Since celosia require warm weather it's important to wait until after the last frost when the weather gets warmer before you can plant them.

The earliest that you can plant celosia in Zone 13a is January. However, you really should wait until February if you don't want to take any chances.

The last month that you can plant celosia and expect a good harvest is probably November. If you wait 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 little bit earlier.
