Toxic to pets

Most likely cause

Overwatering & rot at the base

How to tell

The soil stays wet for days, and the rot starts low: a soft, discolored patch at the base rather than one particular old leaf. Small dark flies around moist potting medium may be fungus gnats. They suggest conditions suitable for breeding, without proving that the surface never dries.

The fix

Stop watering completely. Wait until the top 5 cm (2 in) of soil feel dry before you even think about the next one, and check the pot actually drains. If only some roots are brown and mushy, trim them and repot in fresh, fast-draining mix. If the base itself is soft, the damage is more serious and recovery is uncertain. Only propagate using a method suited to this plant, not arbitrary pieces above the rot. Wear gloves before cutting. The sap can irritate sensitive skin. Keep cuttings out of reach of children and pets because eating the leaves can cause illness.

Too little light

How to tell

The yellowing comes with pale, stretched new growth leaning toward the nearest window. That combination shows that the spot is too dim for a string of pearls.

The fix

Move it to a brighter spot, but keep it out of harsh midday sun, which scorches.

Thirst (underwatering)

How to tell

The soil is bone dry, and the yellowing arrives alongside shriveled pearls rather than soft, mushy growth.

The fix

If the soil is dry, water thoroughly (every 11 to 17 days in summer is the usual pace for a string of pearls), then settle into feeling the soil before every watering rather than watering on a fixed day.

Hungry (but rarely the real culprit)

How to tell

String of pearls grows slowly and needs very little feeding, so a uniform pale-yellow fade after many months without any is possible, but check watering and light first: those are far more common on this plant.

The fix

Use a cactus and succulent fertilizer at half the strength on the label, about every 90 days while it’s actively growing. Overfeeding a slow grower like this does more harm than skipping it.

Simple old age

How to tell

A few of the oldest leaves near the top of the pot shrivel or yellow while the strand tips keep growing plump new ones. That’s normal turnover on a string of pearls, not a symptom.

The fix

Nothing is wrong. Pick off the spent leaves and carry on.
