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, adjust the diagnosis around this plant profile: 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.

How to confirm it

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.
