One of the best tools that you have as gardeners to help us figure out your gardening schedule is the 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 common way of figuring out when it's a good idea to plant gypsophila is to refer to the USDA zone info for Zone 2a.

Planting Calendar for Gypsophila

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

Gypsophila do well in some cold which means that 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 gypsophila in Zone 2a is April. However, you really should wait until May if you don't want to take any chances.

The last month that you can plant gypsophila and expect a good harvest is probably August. You probably don't want to wait any later than that or else your gypsophila may not have a chance to really do well. Starting your gypsophila indoors is a great way to get them started a couple of weeks earlier.

Last Frost Date

On average the last frost has passed is on May 15 in Zone 2a. In the coldest months of winter you can expect an average low temperature of -50°F.

Since the USDA zone info for Zone 2a may not be accurate from year to year the actual date of last frost will vary from year to year. Half of the time in Zone 2a last frost occurs after May 15 so be sure to be ready to cover your gypsophila if you have one of those late frosts.
