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 first chance to plant chamomile in Zone 3a should be estimated by reviewing the USDA zone info.

Planting Calendar for Chamomile

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

Chamomile can survive in moderate cold which means that you can plant them a little earlier in the year than other frost tender plants.

The earliest that you can plant chamomile 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 chamomile and expect a good harvest is probably August. Any later than that and your chamomile may not have a chance to really do well. If you are starting your chamomile indoors then you might be able to get away with starting them a few weeks earlier.

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 may not be accurate from year to year because it is based on the USDA zone info for Zone 3a and it changes from year to year. Half of the time in Zone 3a it frosts late in the year after May 15 so make sure that you are prepared to cover your chamomile if you have a surprise late frost.
