Before planting it is a good idea to find your USDA Zone info to figure out 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 Peru you can figure out when it's a good idea to plant tritoma by looking at the USDA zone info.

Planting Calendar for Tritoma

Frost tolerance for tritoma:	Very tolerant of frost.
When to plant:	Up to 7 weeks before last frost.

Since tritoma do well in cold you can plant them quite a bit earlier in the year than more sensitive plants.

The earliest that you can plant tritoma in Peru 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 tritoma and expect a good harvest is probably September. You probably don't want to wait any later than that or else your tritoma may not have a chance to grow to maturity. Starting your tritoma indoors is a great way to get them started a couple of weeks earlier.
