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 marigolds survive the cold days outdoors or is there another way of overwintering?
Theoretically, marigolds can be overwintered in a warm pot
Marigolds do not 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, hibernation should be successful in many cases.
However, it is easier to harvest the seeds of the marigolds in autumn and to grow new marigolds from them in the coming spring.
tips
In mild regions, the marigolds often seed themselves. Do not cut off all dead flowers immediately during the summer, but let them dry until the elongated seeds fall out of the tubes.
