One of the best tools that you have as gardeners to help us estimate 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 making a decision about when you can plant tagetes is to consult the USDA zone info for Holland.

Planting Calendar for Tagetes

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

Since tagetes are not cold tolerant you need to wait until after the last frost has passed before you can plant them.

The earliest that you can plant tagetes in Holland 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 fully mature. Starting your tagetes indoors is a great way to get them started a little bit earlier.

Last Frost Date
