One of the first steps you take when you are estimating your gardening schedule is find your USDA Zone info. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

A way of making a decision about when you can plant kale is to refer to the USDA zone info for Wilmington.

Planting Calendar for Kale

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

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

The earliest that you can plant kale in Wilmington 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 kale and expect a good harvest is probably September. You probably don't want to wait any later than that or else your kale may not have a chance to fully mature. You can get started a few weeks earlier by starting your kale indoors.

Last Frost Date

On average the last frost is on March 15 in Wilmington. In the coldest months of winter you should expect an average low temperature of 10°F.

Since the USDA zone info for Wilmington is not always accurate the actual date of last frost is different every year. Half of the time in Wilmington you get a frost after March 15 so make sure that you are ready to cover your kale in the event of a late frost.
