About Variegated String of Pearls
Curio rowleyanus 'Variegatus' · also called Variegated String of Beads · houseplant
Variegated String of Pearls is the cream-and-green form of Curio rowleyanus, a trailing succulent with pea-shaped leaves strung along thin stems. The white sectors lack chlorophyll, so it grows slower and needs more bright light than the plain form. Give it gritty soil, infrequent deep watering, and a hanging spot to cascade.
Growth habit: Trailing succulent with wiry stems of spherical leaves; cascades from hanging pots and roots where stems touch soil. Slower and less vigorous than the all-green form because of reduced chlorophyll.
Watch for — Loss of variegation / scorched cream sectors: Too little light reverts to green; too much harsh sun burns the white parts. Aim for bright but filtered light.
What fertiliser variegated string of pearls actually wants — and why
Variegated String of Pearls is a light-feeding succulent — a gentle, low-nitrogen feed a few times in growth keeps it plump without forcing the weak, stretched growth over-feeding causes.
A cactus and succulent formula or a diluted balanced feed with modest, even numbers. Avoid high-nitrogen plant foods — they make a succulent etiolate and grow soft, fracture-prone tissue.
For the language behind the three numbers on the bottle — what nitrogen, phosphorus and potassium each do — see the NPK ratio explained entry. The short version for variegated string of pearls: match the feed to the job the plant is doing right now, not to a generic “plant food” on the shelf.
How often to feed variegated string of pearls, and which months
Feeding only earns its keep while the plant is in active growth and can use the nutrients — pour feed into a dormant or low-light plant and it simply builds up as root-burning salt. For variegated string of pearls:
Feed lightly, about once a month in spring and summer with a half-strength cactus or balanced liquid fertiliser. Over-feeding causes weak, stretched growth. Do not feed in autumn or winter. Keep that to once a month between spring through early autumn (roughly March to September) and stop entirely once growth slows for winter.
The dormant-season rule matters more than the exact interval: skip feeding entirely when variegated string of pearls is resting. For the wider context on indoor feeding rhythms across the seasons, the houseplant fertiliser schedule walks through the year month by month.
What strength to mix for variegated string of pearls
Quarter to half strength at most for variegated string of pearls. Succulents take up very little, and a strong dose burns the fine roots before the plant can use it.
Feeding always goes onto already-damp soil, never dry roots — water variegated string of pearls first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the variegated string of pearls watering schedule.
Signs you are over-feeding variegated string of pearls
Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for variegated string of pearls:
- Stretched, leggy, pale growth with widely spaced leaves.
- A white salt crust on the soil or around the pot rim.
- Brown, crisped leaf tips and edges.
- Soft, mushy tissue at the base — over-feeding plus damp soil rots it.
Signs you are under-feeding variegated string of pearls
- Uncommon — succulents tolerate lean conditions well.
- Very slow growth and dull, faded colour over a long period.
- Older leaves shed faster than new ones replace them in a tired old mix.

Flushing and leaching the salts
Feed lightly enough and you rarely need to flush, but once a year run plain water through the pot of variegated string of pearls until it drains clear, and refresh the gritty mix every 2-3 years.
Organic vs synthetic feeds for variegated string of pearls
Organic options
A heavily diluted seaweed or worm-casting feed once or twice in summer. UK: a drop of Westland seaweed feed; US: quarter-strength Espoma Cactus! or Dr. Earth liquid. Fresh free-draining mix matters more than any feed.
Synthetic / liquid feeds
A dedicated cactus/succulent liquid at quarter to half strength — UK: Baby Bio Cacti & Succulent Drip Feeders or Westland; US: Miracle-Gro Succulent Plant Food or Schultz Cactus Plus.
Brand names are examples, not endorsements, and UK and US ranges differ — check the label’s own NPK and dilution rate, since formulations change.

What does over-feeding variegated string of pearls look like?

Soft, mushy tissue at the base — over-feeding plus damp soil rots it. Feeding variegated string of pearls like a leafy houseplant is the classic error — it produces a flush of pale, stretched, floppy growth that never firms up and is prone to rot at the base.
Should I flush the soil of variegated string of pearls?
Feed lightly enough and you rarely need to flush, but once a year run plain water through the pot of variegated string of pearls until it drains clear, and refresh the gritty mix every 2-3 years.
