The best way to tell if a String of Pearl plant is dying is via the quality of its pearls. Monitor the leaves and take appropriate action to prolong life. Flattened, collapsed pearls are signs of underwatering. Burst, mushy, and shriveled pearls are signs of excessive hydration, which invite pests, root rot, and eventual death. Prune dead stems and leaves, and re-pot in terra-cotta or clay pots to ensure soil drainage. Make sure pots are not too big for the plants and keep soil level high (1 inch from rim) to ensure adequate aeration. Leggy stems, and scattered pearls are signs of inadequate sunlight, while scarred and dry pearls are signs of sun overexposure. Falling pearls are common in the winter when temperatures drop too low.
