How to plant longevity flowers to bloom again after they finish blooming?

The longevity flower is native to Africa. It likes a warm, slightly humid and sunny environment. It is not cold-tolerant. The suitable growth temperature is 15-25℃. If the high temperature exceeds 30℃ in summer, the growth will be stunted. In winter, the indoor temperature needs to be 12-15℃. Below 5℃, the leaves will turn red and the flowering period will be delayed. During the winter and spring flowering period, if the room temperature exceeds 24°C, flowering will be inhibited. If the temperature is around 15°C, longevity flowers will bloom continuously.

Kalanchoe is drought tolerant and has no strict requirements on soil, preferring fertile sandy loam soil. Kalanchoe is a short-day plant and is sensitive to photoperiod response. For well-grown plants, flower buds will bloom after 3 to 4 weeks of short-day exposure (8 to 9 hours of light per day).
