String of Pearls Care Guide

💧 Watering

String of Pearls stores water in its spherical leaves, so it needs much less water than most houseplants. Water thoroughly when the soil is completely dry — push your finger about an inch into the soil, and if it feels dry, it's time. In summer, this is typically every 7-10 days. In winter, stretch to every 2-3 weeks. The key sign that your String of Pearls needs water is the pearls themselves: plump, round pearls mean the plant is well-hydrated, while slightly oval or wrinkled pearls indicate it's thirsty. This visual cue is more reliable than any watering schedule. When you water, soak the soil thoroughly until water runs from the drainage holes, then let it drain completely. Never let the pot sit in a saucer of water. Bottom watering works particularly well for String of Pearls — sit the pot in a few inches of water for 10-15 minutes, then remove and let drain. This avoids wetting the crown and stems, which reduces rot risk. Use room-temperature water and avoid getting the pearls themselves wet, especially the dense crown where stems emerge from the soil — moisture trapped there is the primary cause of crown rot.

☀️ Light Requirements

String of Pearls needs bright light — 6-8 hours daily is ideal. An east- or west-facing window works perfectly, providing bright light without the intensity of midday summer sun. South-facing windows can work but may need sheer curtain filtering during peak summer months, as intense direct afternoon sun can scorch the pearls, turning them brown and dry. That said, String of Pearls handles more direct light than many indoor plants. Morning sun is ideal: it's bright enough to keep the plant compact and healthy without the scorching intensity of afternoon rays. In too little light, the stems will stretch with large gaps between pearls (etiolation), and the pearls themselves become smaller and paler. The plant may also stop trailing and start growing upward, reaching for light. If you notice any of these signs, move to a brighter spot immediately. In winter, when daylight hours are shorter, supplement with a grow light if your String of Pearls starts stretching. The plant needs consistent brightness year-round, not just in summer.

🌡️ Humidity & Temperature

String of Pearls prefers low to average humidity — 30-50% is ideal, which is typical of most indoor environments. Unlike tropical houseplants, it does not benefit from misting, pebble trays, or humidifiers. In fact, high humidity (above 60%) is detrimental: it slows soil drying, increases rot risk, and can promote fungal issues on the delicate pearl-like leaves. Good air circulation is far more important than humidity for this plant. A gentle air flow around the trailing stems helps moisture evaporate from the soil surface and crown area, reducing the risk of the rot that kills more String of Pearls than any other factor. Avoid placing the plant in bathrooms or kitchens where humidity spikes regularly. Temperature-wise, String of Pearls prefers 60-80°F (15-27°C) during the growing season. It can tolerate brief dips to 50°F (10°C) but prolonged cold causes the water-filled pearls to burst and turn mushy. Keep away from cold windows in winter and hot radiators year-round.

🧪 Fertilizing

String of Pearls is a light feeder. During the growing season (spring through early fall), feed once a month with a balanced liquid fertilizer diluted to quarter strength — this plant is sensitive to over-fertilizing, and a quarter-strength dose is safer than half-strength. A standard houseplant fertilizer (10-10-10 or similar) or a cactus/succulent formula both work well. Apply to moist soil only — never fertilize dry roots. Stop fertilizing completely from November through February. Over-fertilizing causes rapid, weak growth that's more susceptible to rot and pest damage. It can also burn the delicate roots and cause pearl drop (healthy-looking pearls suddenly falling off the stems). If you notice salt buildup on the soil surface (white crusty deposits), flush the soil thoroughly with plain water. For an organic alternative, diluted worm casting tea provides gentle nutrition without burn risk. Newly repotted plants don't need fertilizer for the first 6-8 weeks.

✂️ Propagation

String of Pearls is one of the easiest succulents to propagate — stem cuttings root readily and quickly. This is also the best way to rejuvenate a leggy or sparse plant: trim healthy stems and root them to create a fuller pot. Spring and summer are ideal, but cuttings can root any time the plant is actively growing.
