Since kale are moderately cold tolerant you can plant them just a bit earlier in the year than other plants that might not handle the cold.

The last month that you can plant kale and expect a good harvest is probably October. You probably don't want to wait any later than that or else your kale may not have a chance to fully mature. Starting your kale indoors is a great way to get them started a little bit earlier.
