Shriveling Pearls
Insufficient Water
One of the primary reasons for shriveling in String of Pearls is inadequate watering. While these succulents do not require frequent watering, they still need a consistent moisture supply to maintain their plump appearance. If you’ve neglected to water your plant for an extended period, it’s likely the cause of the shriveling. To remedy this, water your plant thoroughly but ensure the soil is well-draining to prevent waterlogging.
Root Rot
Over-watering or poorly draining soil can lead to root rot, a common issue for many succulents, including String of Pearls. Root rot hampers the plant’s ability to absorb water, causing the pearls to shrivel. If you suspect root rot, check the roots for any mushy, brown sections and trim them away. Repot the plant in fresh, well-draining soil.
Pests
Infestations of pests such as aphids, mealybugs, or scale insects can also cause the plant to shrivel. These pests suck the sap from the plant, depriving it of essential nutrients. Regularly inspect your plant for signs of pests and treat infestations promptly with insecticidal soap or neem oil.

Inadequate Sunlight
String of Pearls requires adequate sunlight for photosynthesis. Insufficient light can lead to a lack of energy, causing the plant to wilt and shrivel. Ensure your plant receives bright, indirect light for several hours each day.
Drying Up
Watering Issues
If your String of Pearls is drying up, it could be due to prolonged under-watering. While these plants are drought-tolerant, they still need periodic watering to stay hydrated. Water your plant when the top inch of soil feels dry to the touch.
Mechanical Damage
String of Pearls is not cold-hardy and can suffer significant damage in freezing temperatures. If exposed to cold for too long, the plant may dry up and die. Protect your plant from frost by moving it indoors during cold weather.
Mushy Texture
Advanced Root Rot
A mushy texture in String of Pearls is often a sign of advanced root rot. At this stage, the disease may be too severe to save the entire plant. Salvage healthy cuttings and propagate them to grow new plants.
Turning Brown
Sun Scorch
Excessive direct sunlight can scorch the leaves of String of Pearls, causing them to turn brown. While the plant does need light, it should be shielded from harsh, direct sun. Move the plant to a spot with filtered light or use a sheer curtain to protect it from intense sunlight. Mine have done exceptionally well on my north-facing shaded porch. They don’t get direct sun for more than a few minutes each day.
Turning Yellow
Over-Fertilizing
Yellow leaves can indicate over-fertilizing. Excess fertilizer can accumulate in the soil, leading to root damage and nutrient imbalances. Flush the soil with water to remove excess fertilizer and reduce the frequency of fertilization.
Nutrient Deficiency
Yellowing can also result from a lack of essential nutrients, particularly nitrogen. Use a balanced, diluted fertilizer during the growing season to provide the necessary nutrients.
White Spots
Cold Exposure
White spots can appear if the plant is exposed to cold temperatures. Move the plant indoors or to a warmer location to prevent further damage.
Pest Infestation
Mealybugs and scale insects can leave white, cotton-like spots on the plant. Treat infestations with appropriate pesticides and regularly inspect your plant to catch issues early.
Dropping Leaves
Lack of Sunlight
Insufficient light is a common cause of leaf drop in String of Pearls. Ensure the plant receives adequate light to prevent leaf loss.
Poor Nutrition
Nutrient deficiencies can also lead to dropping leaves. Use a balanced fertilizer to provide the necessary nutrients.
Prevention and Care Tips
- Watering: Water thoroughly but allow the soil to dry out between waterings. Avoid waterlogging by using a well-draining soil mix.
- Light: Provide bright, indirect sunlight. If indoors, place near a south or west-facing window with filtered light.
- Soil: Use a well-draining succulent or cactus mix to prevent root rot.
- Fertilizing: Fertilize sparingly using a balanced, diluted fertilizer during the growing season. Avoid over-fertilizing.
- Pest Control: Regularly inspect the plant for pests and treat any infestations promptly with insecticidal soap or neem oil.
- Temperature: Protect the plant from frost and extreme cold. Maintain a temperature range of 50-85°F (10-29°C).
