About Kalanchoe Rhombopilosa

Kalanchoe rhombopilosa · also called pies from heaven, alligator kalanchoe · houseplant

A small, slow Madagascan curiosity with fan-shaped silvery-grey leaves marbled in chocolate-brown mottling and edged with scalloped 'teeth'. It stays compact and shrubby, ideal for collectors of unusual succulents. Leaves drop and root readily. Easy if kept dry and bright, and, like all Kalanchoe, toxic to cats and dogs.

Mature size: Compact, typically 15-30 cm tall and wide; rarely larger as a houseplant.

Watch for — Root rot: This rot-prone species collapses fast if overwatered. Use a very gritty mix and water only when the soil is completely dry.

How to tell kalanchoe rhombopilosa needs repotting

Repotting on a calendar is less reliable than reading the plant. For kalanchoe rhombopilosa, 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 rhombopilosa

Every 2–3 years, into bone-dry mix. Kalanchoe Rhombopilosa's growth habit — slow-growing, small branching succulent forming a low, twiggy shrublet of fan-shaped mottled leaves. — sets the pace. A small, slow Madagascan curiosity with fan-shaped silvery-grey leaves marbled in chocolate-brown mottling and edged with scalloped 'teeth'. It stays compact and shrubby, ideal for collectors of unusual succulents. Leaves drop and root readily. Easy if kept dry and bright, and, like all Kalanchoe, toxic to cats and dogs.

What size pot to step kalanchoe rhombopilosa up to

Use a pot only one size up — or even the same pot with fresh gritty mix if the roots have room. Kalanchoe Rhombopilosa 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 rhombopilosa

Spring or summer, while kalanchoe rhombopilosa 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 rhombopilosa

Repot dry. Do not water kalanchoe rhombopilosa 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 very gritty, fast-draining 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 rhombopilosa 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 rhombopilosa 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 rhombopilosa

Kalanchoe Rhombopilosa wants very gritty, fast-draining succulent mix. Use a mineral-heavy cactus mix with abundant pumice or grit. Excellent drainage is critical, as its fine roots rot quickly in moisture-retentive soil. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.
