One of the best tools that you have as gardeners to help us estimate your gardening schedule is the USDA zone info. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

The USDA zone info for Winterset should be used to figure out when it's possible to plant dill.

Planting Calendar for Dill

Frost tolerance for dill:	Tolerant of a very small amount of frost.
When to plant:	Up to 3 weeks before last frost.

Dill are barely cold tolerant which means that you can plant them slightly earlier than other plants that might not handle the cold.

The earliest that you can plant dill in Winterset is March. However, you really should wait until April if you don't want to take any chances.

The last month that you can plant dill and expect a good harvest is probably August. You probably don't want to wait any later than that or else your dill may not have a chance to grow to maturity. You can get started a little bit earlier by starting your dill indoors.

Last Frost Date

On average the last frost when the weather gets warmer is on April 15 in Winterset. You should expect an average low temperature of -20°F in the coldest months of winter.

Since the USDA zone info for Winterset is not always accurate the actual date of last frost is different every year. Half of the time in Winterset you get a frost after April 15 so be sure to be ready to protect your dill in the event of one of those late frosts.
