Before planting it is a good idea to find your USDA Zone info to determine 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 Rhinelander you can estimate when it's possible to plant matricaria by reviewing the USDA zone info.

Matricaria do ok in mild cold which tells us that you can plant them a bit earlier in the year than plants that are more sensitive to the cold.

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