String of Fishhooks Care (Curio radicans)

Curio radicans prefers bright, indirect light with some gentle direct sun each day.

• Provide 4–6 hours of bright, indirect light, such as near an east- or north-facing window or in lightly shaded outdoor spots.
• Allow soft morning sun but protect from intense midday or afternoon sun, which can scorch leaves and fade the String of Fishhooks color.
• In winter, move the plant to a brighter position or closer to a window to compensate for shorter days and weaker light.

Curio radicans needs infrequent, thorough watering and fast-draining soil.

• Water only when the top 3–5 cm of soil feel completely dry, then water deeply so excess drains away.
• Reduce watering in fall and winter, as growth slows; the soil should stay dry for longer periods without stressing the plant.
• Watch leaves for signals: firm, plump leaves indicate enough moisture; soft, yellowing, or mushy leaves suggest overwatering and possible root rot.

This succulent prefers warm, dry conditions with protection from frost and extreme heat.

• Aim for 65–80°F (18–27°C) during active growth, as this range supports steady development and healthy foliage.
• Protect the plant from temperatures below 40°F (4°C); brief dips may be tolerated, but freezing conditions damage tissues and can kill roots.
• In hot spells above 90°F (32°C), give light shade, extra airflow, and avoid watering during the hottest part of the day to limit stress.

Curio radicans handles typical indoor humidity well and rarely needs special adjustments.

• Aim for 30–50% humidity; the plant stays healthiest in this moderate, dry-leaning range.
• Dry indoor air is usually tolerated, but very hot, forced-air heating can speed leaf shriveling.
• If leaves wrinkle despite correct watering, increase humidity slightly with a nearby pebble tray or by grouping plants.

Curio radicans prefers a very fast-draining, gritty mix that mimics arid, rocky soils.

• Use a cactus/succulent base mix amended with extra mineral material such as pumice, perlite, or coarse sand for sharper drainage.
• Aim for a loose, airy texture that dries quickly between waterings while still holding roots firmly in place.
• Keep pH slightly acidic to neutral, around 6.0–7.0, which most commercial succulent mixes already provide.
• Avoid dense, peat-heavy or clay-like mixes that stay wet, since these encourage root rot and stem collapse.

This species is highly suitable for container growing, especially in hanging baskets or high shelves.

• Choose a shallow but wide container to accommodate its fibrous roots and trailing stems without creating a deep water reservoir.
• Opt for clay or terra-cotta pots when extra evaporation is needed, as these materials help prevent prolonged moisture around the roots.
• Ensure drainage holes are unobstructed and elevate the pot slightly so excess water can exit rapidly after each watering.

Curio radicans is a light feeder that benefits from modest nutrition during active growth.

• Use a balanced liquid fertilizer (for example 10-10-10 or 20-20-20) diluted to 25–50% strength.
• Feed every 4–6 weeks in spring and summer while vines of String of Fishhooks are actively growing.
• Skip or greatly reduce feeding in fall and winter when growth slows.
• Avoid rich compost or heavy slow-release products that keep soil wet or burn roots.

Curio radicans responds well to light pruning that maintains shape and encourages fuller growth.

• Best time is late winter to early spring, just before new growth begins.
• Remove dead, shriveled, or damaged stems with clean, sharp scissors or snips.
• Shorten overly long or sparse strands to encourage branching and a denser trailing form.
• Take tip pieces from healthy stems, not woody bases, to avoid weakening the plant.

This plant prefers slightly snug conditions and only needs infrequent repotting.

• Repot every 2–3 years or when roots circle the pot, emerge from drainage holes, or growth slows.
• Choose late winter to early spring for moving Curio radicans to a new container.
• Step up only 2–5 cm in pot diameter and use a sharp-draining succulent mix.
• Water lightly after repotting and keep in bright, indirect light for 7–10 days to reduce root stress.

Curio radicans is commonly propagated from stem cuttings taken from healthy trailing vines.

• Take 7–10 cm cuttings in spring or summer, selecting firm, non-flowering stems.
• Strip lower leaves, then lay cuttings on or slightly insert into a gritty, well-drained succulent mix.
• Maintain bright, indirect light and keep the mix barely moist, never wet, to prevent rot.
• Roots usually form in 2–4 weeks; then pot several cuttings together for a fuller plant.

Curio radicans is tender to frost and needs simple winter protection in cold climates.

• Bring container plants indoors before temperatures drop near 40°F, providing bright light and dry soil.
• In mild regions without hard frost, use a very free-draining mix and avoid winter watering outdoors.
• Do not expose foliage to freezing or cold, wet drafts near windows or doors.
• Resume normal watering and feeding only when days lengthen and new growth appears.
