Plant + symptom guide

Hoya 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 hoya, adjust the diagnosis around this plant profile: Hoyas prefer bright light, airy mix, and dry-down. Yellow leaves, wrinkling, and no blooms usually need a root, light, and watering pattern check.

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 wrinkled leaves come with dry roots or dead roots.

Inspect nodes and leaf backs for mealybugs.
