String-of-Tears Care (Curio citriformis)

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

• Provide 4–6 hours of bright, indirect light daily; soft morning sun is ideal, while harsh afternoon sun should be filtered through a sheer curtain or light shade.
• Plant can tolerate light partial shade, but stems may stretch and lose density if it receives under 3–4 hours of strong ambient light.
• In summer, protect String-of-Tears from scorching midday sun to prevent leaf scorch; in winter, move it to the brightest spot available to compensate for shorter days.

Curio citriformis is a drought-tolerant succulent that prefers infrequent, deep watering.

• Allow the top 3–5 cm of soil to dry fully before watering again; the foliage should feel firm, not soft or wrinkled, between waterings.
• Use sharply draining, gritty soil and a pot or bed that does not stay soggy, as consistently wet roots cause yellowing leaves, mushy stems, and root rot.
• In spring and summer, watering is typically needed more often; reduce frequency in fall and winter, when cooler temperatures and slower growth mean the soil stays moist longer.

This succulent thrives in warm, dry conditions and dislikes cold, damp environments.

• Aim for 65–80°F (18–27°C) during active growth for best performance, with good air circulation to reduce the risk of fungal problems.
• The plant tolerates short dips to about 40°F (4–5°C) but should be protected from frost, which can damage or collapse the water-filled leaves.
• In hotter weather above 90°F (32°C), provide light shade and avoid reflected heat from walls or pavement, while in cooler seasons keep it in a frost-free, sheltered position.

This succulent handles typical indoor humidity well and rarely needs special adjustment.

• Aim for 30–50% humidity, similar to most heated or air-conditioned homes.
• Dry air is usually tolerated, but very hot, dry drafts can cause shriveling leaves and faster soil drying.
• If leaves wrinkle despite proper watering, slightly raise local humidity with nearby trays of water or grouped plants rather than misting.

This species needs a very fast-draining, airy mix to protect its roots from excess moisture.

• Use a gritty, sandy mix such as 50–70% cactus/succulent soil blended with coarse perlite or pumice for strong drainage and aeration.
• Maintain a slightly acidic to neutral pH around 6.0–7.0, which suits Curio citriformis and most succulents grown indoors.
• Avoid heavy, peat-dense or clay-based mixes that stay wet, as these promote root rot and swollen, translucent leaves.
• Improve structure further by adding mineral grit or coarse sand, and keep organic components modest so the mix dries within a few days.

This plant is very suitable for container growing due to its trailing, compact root system.

• Choose a shallow, wide pot that allows stems to trail over the rim while preventing excess unused soil that would hold moisture.
• Select terracotta or other porous materials if extra evaporation is needed, especially in cooler or low-light locations.
• Ensure drainage holes are large and unobstructed so water exits quickly and the lower root zone does not remain saturated.

This succulent benefits from modest feeding to support steady growth without stretching.

• Use a balanced liquid fertilizer (around 10-10-10) or cactus blend diluted to 25–50% strength.
• Feed String-of-Tears once every 4–6 weeks in spring and summer when actively growing.
• Avoid compost-heavy mixes; they stay too wet for Curio citriformis roots.
• Stop feeding in fall and winter, when growth naturally slows.

Pruning helps Curio citriformis stay compact, tidy, and free of weak growth.

• Best time is late winter to early spring, before strong new growth starts.
• Use clean, sharp scissors or snips to remove dead, shriveled, or damaged stems.
• Trim overly long or crowded trails to maintain a balanced, fuller shape.
• Cut just above a healthy node to encourage branching and denser foliage.

Curio citriformis prefers slightly tight pots and only occasional repotting.

• Check for roots circling the pot, pushing through drainage holes, or slowed growth as signs to repot.
• Plan to move to a slightly larger container every 2–3 years in spring.
• Use a shallow pot with fast-draining cactus or succulent mix to limit root rot risk.
• Gently loosen the root ball, remove old soil, and water lightly after repotting to reduce stress.

This species is commonly propagated from stem cuttings to create new plants or thicken existing pots.

• Take 5–8 cm healthy stem cuttings in spring or early summer.
• Let cut ends dry and callus for 1–2 days before planting in a gritty, well-draining mix.
• Place cuttings in bright, indirect light and keep soil barely moist until roots form.
• Once rooted and new growth appears, transition to normal Curio citriformis care.

Curio citriformis is not frost hardy and needs protection in regions with cold winters.

• Move container plants indoors before temperatures drop below 40°F.
• Provide bright, indirect light and keep room temperatures around 55–70°F in winter.
• Keep soil on the dry side; water sparingly to prevent cold, wet root conditions.
• Avoid drafts from windows or heaters that cause rapid temperature swings.
