One of the first steps you take when you are determining 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 using the USDA zone info for Brazil you should be able to estimate when you can plant pentas.

Planting Calendar for Pentas

Frost tolerance for pentas:	Not tolerant of frost.
When to plant:	After all chance of frost has passed.

You can not plant pentas until after the last frost when the weather gets warmer because they require warm weather.

The earliest that you can plant pentas in Brazil 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 pentas and expect a good harvest is probably August. Any later than that and your pentas may not have a chance to fully mature. If you are starting your pentas indoors then you might be able to get away with starting them a couple of weeks earlier.

Last Frost Date

The average date of last frost is April 15 in Brazil. It might get as low as -15°F during the coldest months of winter.

Since the USDA zone info for Brazil is not always accurate the actual date of last frost is different every year. Half of the time in Brazil it frosts late in the year after April 15 so make sure that you are ready to cover your pentas if you have one of those late frosts.
