Before planting it is a good idea to find your USDA Zone info to estimate 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 common way of estimating when it's possible to plant scutellaria is to check out the USDA zone info for Peru.

Planting Calendar for Scutellaria

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

It's not a good idea to plant scutellaria until after the last frost when the weather gets warmer because they are not cold tolerant.

The earliest that you can plant scutellaria in Peru 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 scutellaria and expect a good harvest is probably August. Any later than that and your scutellaria may not have a chance to grow to maturity. Starting your scutellaria indoors is a great way to get them started a few weeks earlier.

Last Frost Date

On average the last frost when the weather gets warmer is on April 15 in Peru. You should expect an average low temperature of -15°F in the coldest months of winter.

Remember that USDA zone info for Peru is not always accurate and the actual date of last frost changes from year to year. Since half of the time in Peru you get a frost after April 15 be ready to cover your scutellaria if you have a late frost.
