About Crassula Pyramidalis

Crassula pyramidalis · also called pyramid crassula, stacked crassula · houseplant

Crassula pyramidalis is a curious dwarf South African succulent whose tightly packed, scale-like leaves form perfect square, column-like stacks resembling tiny pagodas. A collector's plant, it needs very bright light, an extremely free-draining mineral mix and careful, sparing watering. Compact and slow, it suits small pots and bright windowsills among other choice succulents.

Mature size: Small: columns reach about 5-12 cm tall, forming low clusters a few centimetres wide.

Watch for — Loss of the stacked form: In weak light the tidy square columns loosen and stretch. Give the brightest spot available to preserve the architectural shape.

How to tell crassula pyramidalis needs repotting

Repotting on a calendar is less reliable than reading the plant. For crassula pyramidalis, 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 crassula pyramidalis

Every 2–3 years, into bone-dry mix. Crassula Pyramidalis's growth habit — slow-growing dwarf succulent forming erect, square columns of densely overlapping leaves; clusters into small colonies of stacked stems with age. — sets the pace. Crassula pyramidalis is a curious dwarf South African succulent whose tightly packed, scale-like leaves form perfect square, column-like stacks resembling tiny pagodas. A collector's plant, it needs very bright light, an extremely free-draining mineral mix and careful, sparing watering. Compact and slow, it suits small pots and bright windowsills among other choice succulents.

What size pot to step crassula pyramidalis up to

Use a pot only one size up — or even the same pot with fresh gritty mix if the roots have room. Crassula Pyramidalis 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 crassula pyramidalis

Spring or summer, while crassula pyramidalis 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 crassula pyramidalis

Repot dry. Do not water crassula pyramidalis 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, mostly mineral 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 crassula pyramidalis 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 crassula pyramidalis 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 crassula pyramidalis

Crassula Pyramidalis wants very gritty, mostly mineral succulent mix. Use a sharply draining blend high in pumice, grit and perlite with minimal organic matter. A shallow clay pot helps the compact root system dry out fast. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting crassula pyramidalis — frequently asked questions

How often should you repot crassula pyramidalis?

Every 2–3 years, into bone-dry mix for crassula pyramidalis. Repot crassula pyramidalis every 2–3 years into a snug pot of very gritty, mostly mineral succulent mix, ideally in spring or summer. Let it sit in dry soil and do not water for about a week afterwards so any nicked roots can callus. Over-potting and watering straight away is what rots succulents.

What size pot does crassula pyramidalis need?

When is the best time of year to repot crassula pyramidalis?

Should you water crassula pyramidalis after repotting?

No — not straight away. Repot crassula pyramidalis 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.

Should you fertilise crassula pyramidalis after repotting?

Not immediately. Wait about 3 weeks after repotting crassula pyramidalis. Fresh mix already contains nutrients, and feeding freshly cut or disturbed roots burns them. Resume your normal feeding routine once you see new growth.
