Before planting it is a good idea to find your USDA Zone info to determine your garden schedule. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

In Globe you can estimate when it's possible to plant asters by reviewing the USDA zone info.

Planting Calendar for Asters

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

Since asters are moderately cold tolerant you can plant them a little earlier in the year than other plants that might not handle the cold.

The earliest that you can plant asters in Globe is January. However, you really should wait until February if you don't want to take any chances.

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

Last Frost Date

In Globe the average date of last frost happens on February 15. It might get as low as 20°F during the coldest months of winter.

Always keep in mind that USDA zone info for Globe is not always accurate and the actual date of last frost changes from year to year. Since half of the time in Globe there is a last frost after February 15 be ready to protect your asters if you have a surprise late frost.
