About Mother of thousands

Kalanchoe daigremontiana · also called mother of thousands, devil's backbone · houseplant

Mother of thousands is a Madagascan succulent that lines its leaf edges with tiny plantlets, each ready to root where it falls. It is easy to grow but toxic: the ASPCA lists Kalanchoe as toxic to cats and dogs, and the dropped plantlets are a real pet and child hazard.

Ideal humidity: 30-50%

Watch for — Soft, mushy stem or yellowing base (root rot): Overwatering or a pot without drainage suffocates the roots and rots the crown.

The watering schedule, season by season

Mother of thousands stores water in its thick leaves and stems, so when in doubt, wait — it survives drought far better than soggy soil. The base rhythm for mother of thousands is when the top 5 cm (2 in) of soil is dry, roughly every 1-2 weeks in growth, but the real interval moves with the season, the light and the pot — so treat the figures below as a starting point and always confirm with the plant itself.

Water deeply, then let the mix dry out before watering again. As a drought-tolerant succulent it rots easily if kept wet; cut watering right back in winter.
