One of the best tools that you have as gardeners to help us determine your gardening schedule is the USDA zone info. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

The first opportunity to plant matricaria in Boston should be figured out by reviewing the USDA zone info.

Matricaria do well in moderate cold which tells us that you can start planting them earlier than other plants that might not handle the cold.

The earliest that you can plant matricaria in Boston 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 matricaria and expect a good harvest is probably September. You probably don't want to wait any later than that or else your matricaria may not have a chance to fully mature. You can get started a little bit earlier by starting your matricaria indoors.

Last Frost Date

The average date of last frost is April 15 in Boston. In the coldest months of winter you can expect an average low temperature of -5°F.

It's important to remember that the actual date of last frost is an average because it is based on the USDA zone info for Boston and it can change quite a bit from year to year. Half of the time in Boston last frost occurs after April 15 so always be ready to protect your matricaria if you have a surprise late frost.
