Why is my cactus growing flowers?
Cacti flower on fresh growth, so if your plant just sits there, unchanging year after year, it’s very unlikely to flower. What you should do is to get the plant to follow its natural growth cycle. It needs to go dormant in winter and then wake up in spring.
While some plants bloom and wither within one day, others will retain their flowers for periods of up to six weeks. Some of the crucial factors that determine how long a cactus flower lasts include the temperature of the surrounding environment and the amount of watering it receives.
Many people remove spent blooms as flowers fade to keep plants healthy and the garden looking its best. If you want to deadhead cactus flowers, wear thick gloves, especially if you have several plants to work with. Long sleeves may be needed sometimes or long pants.
The opening and closing mechanism is triggered by changes in light or intensity or temperature. Cells in the flower expand or contract, causing the flowers to open or close. This behavior is called “nyctinasty.” What a great word to impress your friends with!
