Florist Kalanchoe likes warm, slightly wet and sunny conditions. It is not cold resistant, and the suitable temperature for growth is 15 ~ 25℃. If the high temperature in summer exceeds 30℃, the growth is blocked, and the indoor temperature in winter needs 12 ~ 15℃. Under 5℃, the leaves turned red and the flowering time was delayed. This will inhibit flowering if the room temperature is over 24 ° C during winter and spring flowering. For example, when the temperature is around 15 ° C, Florist Kalanchoe keeps flowering.
Florist Kalanchoe is drought-tolerant and not too strict with the soil, preferring rich sandy loam. Florist Kalanchoe is a short-day plant and is sensitive to photoperiodic reactions.

Then 1/2MS medium was added with 1 mg/l of indolebutyric acid to induce rooting. At room temperature of 25 ~ 27℃, 16 hours of light. After 4 ~ 6 weeks, it can grow small plants.
When selecting seedlings, we should observe the situation of the leaves and choose healthy seedlings with thick and plump leaves.
