About String of Spades

Ceropegia woodii 'Heartless' · also called Ceropegia Heartless · houseplant

Ceropegia woodii 'Heartless', or String of Spades, is a trailing semi-succulent whose leaves are elongated and pointed like a spade rather than a rounded heart, with silver marbling over green. It cascades from baskets and forms bead-like tubers along the stems. Care matches the rosary vine: bright indirect light, gritty soil, dry-down watering, and ASPCA pet-safe.

Mature size: Strands trail to 0.6-2 m (2-6 ft) over time; pointed leaves about 1.5-2.5 cm long.

Watch for — Leggy strands with sparse leaves: Widely spaced leaves and bare runs of stem mean too little light. Move to a brighter indirect spot and trim long bare strands; new compact growth follows as light improves.

How to tell string of spades needs repotting

Repotting on a calendar is less reliable than reading the plant. For string of spades, 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 string of spades

Every 2–3 years, into bone-dry mix. String of Spades's growth habit — trailing semi-succulent vine with spade-shaped leaves; strands cascade from hanging baskets or shelves and form aerial tubers (beads) at the nodes. — sets the pace.

What size pot to step string of spades up to

Use a pot only one size up — or even the same pot with fresh gritty mix if the roots have room. String of Spades 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 string of spades

Spring or summer, while string of spades 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 string of spades

Repot dry. Do not water string of spades 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 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 string of spades 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 string of spades 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 string of spades

String of Spades wants gritty, free-draining succulent or cactus mix. Use a cactus/succulent mix or boost a standard mix with perlite, pumice, or coarse sand for sharp drainage. The shallow roots and tubers rot in heavy, soggy soil. A pot with drainage holes is essential. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting string of spades — frequently asked questions

How often should you repot string of spades?

Every 2–3 years, into bone-dry mix for string of spades. Repot string of spades every 2–3 years into a snug pot of gritty, free-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 string of spades need?

When is the best time of year to repot string of spades?

Should you water string of spades after repotting?

No — not straight away. Repot string of spades 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 string of spades after repotting?

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