With its bright yellow or orange-red flower heads, the marigold is one of the most popular summer bloomers. If the plants thrive particularly well in one location, the question often arises in autumn: Will the marigold survive the cold days outdoors or is there another way to overwinter?
Can marigolds overwinter outdoors?
Tagetes, also known as marigold, are not frost tolerant and cannot survive the winter outdoors. However, overwintering is often possible by placing the plant in a flower pot in a room at 15-20 °C.
Tagetes don't like frost
The marigold, which comes from Mexico, is not frost-tolerant and the first few days of frost often kill the marigold. What is little known, however, is that not all marigold varieties are annuals. If you transplant the marigold into a flower pot and place it in a room where the temperature is between 15 and 20 degrees all day, overwintering should be successful in many cases.
However, it is easier to harvest the marigold seeds in the fall and grow new student flowers from them next spring.
Tip
In mild regions, marigolds often self-exterminate. During the summer, do not cut off all the dead flowers immediately, but let them dry until the elongated seeds fall out of the tubes.
