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.

By checking out the USDA zone info for Zone 3a you will be able to figure out when it's a good idea to plant baby's breath.

Planting Calendar for Baby's Breath

Frost tolerance for baby's breath:	Tolerant of some frost.
When to plant:	Up to 5 weeks before last frost.

Since baby's breath are moderately cold tolerant you can plant them a little bit earlier in the year than more sensitive plants.

The earliest that you can plant baby's breath in Zone 3a 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 baby's breath and expect a good harvest is probably August. If you wait any later than that and your baby's breath may not have a chance to fully mature. You can get started a couple of weeks earlier by starting your baby's breath indoors.

Last Frost Date

In Zone 3a the average date of last frost happens on May 15. In the coldest months of winter you can expect an average low temperature of -40°F.

It's important to remember that the actual date of last frost is not always accurate because it is based on the USDA zone info for Zone 3a and it can change quite a bit from year to year. Half of the time in Zone 3a you get a frost after May 15 so just be sure to be ready to cover your baby's breath if you have one of those late frosts.
