Kalanchoe care

Kalanchoe blossfeldiana

Thirsty’s starting schedule for Kalanchoe: about every 10 days. Check the soil and adjust it to your home.

Watering

Let the soil dry out between waterings, then water thoroughly, and never let the pot sit in water. Water less during slow winter growth. [1][2][3]

Light

Bright light: full sun or bright indirect light indoors, with some shade from strong afternoon sun. In low light it gets spindly. [1][2][3]

Humidity

Humid conditions can encourage leaf-spot diseases. [4]

Soil and potting

A very well-drained potting mix, such as one made for cacti or succulents. [1][2]

Pets

Toxic to cats and dogs; it can cause vomiting, diarrhea and, rarely, an abnormal heart rhythm. [5]
