One of the first steps you take when you are estimating your gardening schedule is find your USDA Zone info. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

The earliest that you can plant statice in Zone 4a should be figured out by referring to the USDA zone info.

Planting Calendar for Statice

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

Since statice 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 statice in Zone 4a 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 statice and expect a good harvest is probably August. Any later than that and your statice may not have a chance to fully mature. Starting your statice indoors is a great way to get them started a few weeks earlier.

Last Frost Date

The average date of last frost is May 15 in Zone 4a. It might get as low as -30°F during the coldest months of winter.

Since the USDA zone info for Zone 4a is not always accurate the actual date of last frost will vary from year to year. Half of the time in Zone 4a last frost occurs after May 15 so make sure that you are prepared to protect your statice if you have a late frost.
