String of Pearls root rot

Root rot is more likely when decline comes with wet soil, sour smell, mushy roots, soft stems, or a sealed pot. It is worth checking carefully before repotting.

For string of pearls, read this symptom alongside how the plant usually behaves: String of pearls usually struggles from too little light, dense soil, or watering before the pearls need it. Mushy pearls are more urgent than a few dry beads.

What to check

Smell the soil and look for sour or swampy odor.

Slide the root ball out only if decline is severe or the pot has no drainage.

Check for brown, mushy roots versus firm pale roots.

Check whether the crown gets light, not just the trailing strands.

Feel pearls for mushy translucence versus dry wrinkling.

Evergreen diagnosis

String of pearls root rot starts at the crown and wet soil

String of pearls root rot often begins when the potting mix stays wet around fine roots and thin stems. The pearls may shrivel, turn translucent, yellow, or collapse from the crown.

This plant needs bright light and fast drainage. In low light, even careful watering can stay wet too long.

Shriveling with damp soil is the warning

A dry string of pearls shrivels because it needs water. A rotting one shrivels while the soil is still damp because the roots can no longer supply the beads.

Lift the strands and inspect the crown. Mushy stems, dark roots, or a sour smell mean the plant needs to be dried, trimmed, and restarted in fresher mix.

Healthy strands are worth propagating

If the crown is rotting, save firm green strands from beyond the damaged section. String of pearls roots readily from nodes when conditions are bright and airy.

Lay cuttings on a gritty mix and keep it barely moist until rooted. Avoid burying stems deeply in wet soil.

Careful next steps for String of Pearls

  1. Step 1

    Isolate the plant if rot is severe or pests are also present.

  2. Step 2

    Trim dead roots and repot into a faster-draining mix if roots are mushy.

  3. Step 3

    Do not fertilize while roots are recovering.

Overwatered Plant Signs

An overwatered plant often looks thirsty. Wet soil, yellow lower leaves, drooping, fungus gnats, and soft stems are stronger clues than one symptom alone.
