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.

A way of estimating when it's possible to plant coral bells is to use the USDA zone info for Brazil.

Planting Calendar for Coral Bells

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

Coral Bells are one of those plants that can tolerate a little bit of cold weather which means that you can start planting them earlier than other frost tender plants.

The earliest that you can plant coral bells in Brazil is February. However, you really should wait until March if you don't want to take any chances.

The last month that you can plant coral bells and expect a good harvest is probably September. If you wait any later than that and your coral bells may not have a chance to really do well. You can get started a little bit earlier by starting your coral bells indoors.

Last Frost Date

In Brazil the average date of last frost happens on April 15. You can expect an average low temperature of -15°F in the coldest months of winter.

Remember that the actual date of last frost is not always accurate because it is based on the USDA zone info for Brazil and it changes from year to year. Half of the time in Brazil last frost occurs after April 15 so always be ready to cover your coral bells if you have a late frost.
