Before planting it is a good idea to find your USDA Zone info to determine your garden schedule. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

One way of estimating when you can plant kale is to use the USDA zone info for Henderson.

Planting Calendar for Kale

Frost tolerance for kale:	Tolerant of some frost.
When to plant:	Up to 5 weeks before last frost.

Since kale are one of those plants that can tolerate a little bit of cold weather you can plant them a little earlier in the year than other plants that might not handle the cold.

The earliest that you can plant kale in Henderson 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 kale and expect a good harvest is probably October. If you wait any later than that and your kale may not have a chance to really do well. If you are starting your kale indoors then you might be able to get away with starting them a few weeks earlier.

Last Frost Date

The average date of last frost is February 15 in Henderson. In the coldest months of winter you can expect an average low temperature of 20°F.

Since the USDA zone info for Henderson is not always accurate the actual date of last frost is different every year. Half of the time in Henderson there is a last frost after February 15 so just be sure to be ready to cover your kale in the event of a surprise late frost.
