One of the best tools that you have as gardeners to help us figure out your gardening schedule is the 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.

A common way of figuring out when to plant tagetes is to refer to the USDA zone info for Peru.

Planting Calendar for Tagetes

Frost tolerance for tagetes:	Not tolerant of frost.
When to plant:	After the last frost has passed.

Tagetes require warm weather which tells us that it is important to wait until it warms up after all chance of frost has passed before you can plant them.

The earliest that you can plant tagetes 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 tagetes and expect a good harvest is probably August. You probably don't want to wait any later than that or else your tagetes may not have a chance to grow to maturity. You can get started a few weeks earlier by starting your tagetes indoors.

Last Frost Date

On average the last frost is on April 15 in Peru. In the coldest months of winter you should expect an average low temperature of -15°F.

Since the USDA zone info for Peru is not always accurate the actual date of last frost can change quite a bit from year to year. Half of the time in Peru you get surprised by a frost after April 15 so be sure to be ready to cover your tagetes in the event of a surprise late frost.
