Planting Calendar for Kale

When to plant:	Up to 5 weeks before last frost.

Since kale do well in moderate cold you can plant them just a bit earlier in the year than plants that are more sensitive to the cold.

The last month that you can plant kale and expect a good harvest is probably October. Any later than that and your kale may not have a chance to fully mature. If you are starting your kale indoors then you might be able to get away with starting them a little bit earlier.
