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.

In Peru you can figure out when it's possible to plant bee balm by reviewing the USDA zone info.

Planting Calendar for Bee Balm

Frost tolerance for bee balm:	Tolerant of a very small amount of frost.
When to plant:	Up to 3 weeks before last frost.

Bee Balm tend to make it in very little cold which tells us that you can plant them just a tiny bit earlier in the year than plants that are more sensitive to the cold.

The earliest that you can plant bee balm in Peru 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 bee balm and expect a good harvest is probably August. Any later than that and your bee balm may not have a chance to fully mature. You can get started a little bit earlier by starting your bee balm indoors.

Last Frost Date

In Peru 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.

Since the USDA zone info for Peru is not always accurate the actual date of last frost changes from year to year. Half of the time in Peru you get a frost after April 15 so make sure that you are prepared to protect your bee balm if you have a surprise late frost.
