On a jade plant, root rot primarily manifests as brown, mushy, and foul-smelling roots that resemble overcooked noodles, contrasting sharply with healthy, firm, and light-colored roots. Beyond the roots, root rot often presents visible symptoms in other parts of the plant, indicating severe distress.
Diagnosing Root Rot at the Source
The most direct way to identify root rot is by inspecting the roots themselves. To do this:
- Gently lift the jade plant from its pot.
- Carefully brush away the soil from the root ball to get a clear view.
Once exposed, observe the following characteristics:
| Root Condition | Appearance | Texture | Odor |
|---|---|---|---|
| Healthy | Light-colored (often white or tan) | Firm, pliable | Earthy, fresh |
| Root Rot | Dark brown or black | Mushy, slimy, soft (like overcooked noodles) | Foul, decaying, sulfuric |
Visible Symptoms of Root Rot on Jade Plants
While the roots show the most definitive signs, root rot will also cause symptoms to appear above the soil line as the plant struggles to absorb water and nutrients.
- Yellowing or Drooping Leaves: One of the earliest signs can be leaves turning yellow, becoming soft, or starting to droop and appear lifeless, even if the soil feels damp.
- Mushy Stems or Base: The stem of a jade plant, especially near the soil line, may feel soft, mushy, or discolored (dark brown/black). This indicates the rot has spread upwards.
- Stunted Growth: An affected jade plant will stop growing new leaves and may appear generally unhealthy or stunted compared to its usual vigor.
- Leaf Drop: In severe cases, the plant may prematurely drop its leaves, often starting with the lower ones.
- Wilting: Despite being watered, the plant will appear to be constantly thirsty and wilted because the damaged roots cannot take up water effectively.
What Causes Root Rot?
Root rot in jade plants is almost always caused by overwatering or poor drainage. Jade plants, being succulents, store water in their leaves and stems and prefer their soil to dry out completely between waterings. Consistently wet soil deprives the roots of oxygen, creating an anaerobic environment where harmful fungi and bacteria thrive, leading to root decay.
