Kalanchoe millotii · also called millot's kalanchoe, fuzzy kalanchoe · houseplant

Kalanchoe millotii is a Madagascan shrubby succulent with soft, felted grey-green leaves edged in shallow teeth, giving it a fuzzy, sage-like look. It branches into a compact little bush and bears small greenish-yellow flowers. It likes bright light, dry roots and warmth, and is undemanding indoors. All parts are toxic to cats and dogs.

Mature size: Typically 30-45 cm tall and 20-40 cm wide as a tidy indoor shrublet.

Watch for — Leggy, stretched growth: Sparse spacing between leaves means insufficient light; move to a brighter window to restore the compact, fuzzy form.

How to tell kalanchoe millotii needs repotting

Repotting on a calendar is less reliable than reading the plant. For kalanchoe millotii, watch for these signs:

Roots growing out of the drainage holes, or the rootball lifting the plant proud of the rim.
Soil that has shrunk away from the pot sides and no longer holds water.
The pot is unstable because the plant has grown top-heavy.
Old, compacted, broken-down mix that stays wet too long — for a succulent that is a rot risk, so refresh it even if the pot size is fine.

How often to repot kalanchoe millotii

Every 2–3 years, into bone-dry mix. Kalanchoe Millotii's growth habit — upright, branching shrublet that forms a small, dense bush over time. — sets the pace. Kalanchoe millotii is a Madagascan shrubby succulent with soft, felted grey-green leaves edged in shallow teeth, giving it a fuzzy, sage-like look. It branches into a compact little bush and bears small greenish-yellow flowers. It likes bright light, dry roots and warmth, and is undemanding indoors. All parts are toxic to cats and dogs.

What size pot to step kalanchoe millotii up to

Use a pot only one size up — or even the same pot with fresh gritty mix if the roots have room. Kalanchoe Millotii stores water and rots in a large pot of slow-drying soil. A tight terracotta pot that dries fast is far safer than a generous plastic one. Never up-pot a succulent by several sizes.

The best time of year to repot kalanchoe millotii

Spring or summer, while kalanchoe millotii is in active growth and warm, is best — roots recover fastest then, and the plant is not sitting in cool damp soil. Avoid repotting a succulent in winter dormancy.

Step-by-step: repotting kalanchoe millotii

Repot dry. Do not water kalanchoe millotii for several days first. Working with dry roots and dry mix dramatically lowers the rot risk for a succulent.
Pick a snug, fast-draining pot. Choose terracotta one size up at most, with a drainage hole. Have gritty gritty, free-draining cactus or succulent mix ready.
Tip it out and clean the roots. Slide the plant out, crumble off the old soil, and trim any black, mushy or dead roots with clean snips.
Pot into dry mix. Set kalanchoe millotii at its original depth in dry gritty mix, firming gently. Do not bury the stem deeper than it was.
Wait a week before watering. Leave it completely dry and out of harsh sun for about 7 days so any damaged roots callus. Only then water lightly.

Aftercare

Keep kalanchoe millotii completely dry and out of fierce sun for about a week so any nicked roots callus before they meet moisture; watering a freshly repotted succulent is the classic way to rot it. Then resume the normal lean, dry rhythm. Do not fertilise for about 3 weeks — fresh mix already carries nutrients and feeding freshly disturbed roots scorches them.

The right soil mix for kalanchoe millotii

Kalanchoe Millotii wants gritty, free-draining cactus or succulent mix. A cactus compost blended with plenty of perlite or pumice prevents soggy roots. Choose a pot with drainage holes; terracotta helps wick excess moisture. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting kalanchoe millotii — frequently asked questions

What size pot does kalanchoe millotii need?

When is the best time of year to repot kalanchoe millotii?

Should you water kalanchoe millotii after repotting?

No — not straight away. Repot kalanchoe millotii into dry mix and wait about a week before the first watering so any damaged roots callus over. Watering a freshly repotted succulent is the single most common way to rot one.
