Crassula pellucida subsp. marginalis 'Variegata' · also called calico kitten, variegated crassula · houseplant

Crassula 'Calico Kitten' is a trailing succulent with small heart-shaped leaves splashed cream, green, pink and rose, blushing deeper in bright light. It cascades from pots and hanging baskets, wants gritty fast-draining soil and only occasional water, and produces tiny white star flowers. A charming, easy succulent that is toxic to cats and dogs.

Mature size: Stays only a few centimetres tall but trails to 20-30 cm or more, spilling over pot edges as a draping groundcover.

Watch for — Overwatering and rot: The fine roots and thin stems rot easily in wet soil. Let the gritty mix dry between waterings and cut back sharply in winter.

How to tell crassula pellucida needs repotting

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

Every 2–3 years, into bone-dry mix. Crassula Pellucida's growth habit — low, trailing and mat-forming succulent with slender stems of small heart-shaped leaves. cascades beautifully from hanging baskets and roots where stems touch soil; bears tiny white star flowers. — sets the pace.

What size pot to step crassula pellucida up to

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

Spring or summer, while crassula pellucida 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 pellucida

Repot dry. Do not water crassula pellucida 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, fast-draining succulent or cactus 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 pellucida 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 pellucida 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 pellucida

Crassula Pellucida wants gritty, fast-draining succulent or cactus mix. Use a cactus/succulent compost with added perlite, pumice or grit for sharp drainage. A pot with drainage holes is essential; the fine roots and trailing stems rot quickly in wet, heavy soil. 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 pellucida — frequently asked questions

How often should you repot crassula pellucida?

Every 2–3 years, into bone-dry mix for crassula pellucida. Repot crassula pellucida every 2–3 years into a snug pot of gritty, fast-draining succulent or cactus 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 pellucida need?

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

Should you water crassula pellucida after repotting?

No — not straight away. Repot crassula pellucida 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 pellucida after repotting?

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