How this shows up on a Aloe vera
Mushy tissue at the base of the aloe vera
Soft, discoloured tissue appears where the leaves join the stem of the aloe vera, and the compost smells stale rather than earthy.
A plant that stores its own water has little use for more. Kept in well-drained soil that stays wet, the stored tissue takes up water it cannot release and the cell walls give way.
Telling it apart: Lift the plant. Roots that are black and slimy confirm rot; pale, dry roots mean the soft tissue has another cause.

Most likely too much water for a plant that stores its own
Ranked higher because Aloe vera's recorded problems point this way.
Aloe vera stores water in its own tissue, which makes it more sensitive to wet soil than most leafy plants, so this reading is stronger for it.

- Loam; pH Acid or Alkaline or Neutral RHS · read 11 September 2026
Why: A aloe vera built to survive drought has little use for extra water.
What to try:
- Stop watering and let the compost dry right through.
- Remove soft leaves, and check the base of the stem for rot.
What would settle it: Press a leaf gently. A thirsty succulent leaf is wrinkled and springs back; a waterlogged one is swollen and stays dented.
Most likely rot at the base of the stem
- Well-drained RHS · read 11 September 2026
- Loam; pH Acid or Alkaline or Neutral RHS · read 11 September 2026
Why: A stem that is soft or dark at the soil line, in wet compost, has usually been invaded by the fungi and bacteria that thrive where roots and stems sit wet.
What to try:
- Look for any firm, healthy stems or tips above the damage; cuttings from those may root even if the base cannot be saved.
- Throw away the affected compost rather than reusing it, and wash the pot before using it again.
What would settle it: Cut a small slice from the affected stem. Discoloured tissue running up inside it is rot; a clean pale centre means the damage is on the surface.
Most likely cold

Why: Soft, dark patches rather than crisp ones are damaged tissue rather than dried tissue.
What to try:
- Move it away from the glass at night, or keep the curtain on the room side of the aloe vera.
- Leave damaged leaves until new growth appears, then remove the worst of them.
What would settle it: Where the aloe vera sits at night, and what the glass feels like at that hour. Damage that appeared after one cold night, on the side facing the window, is the pattern.
Less likely for a Aloe vera, still possible

- How can I tell which one it is on my Aloe vera?
- Where is it soft? At the soil line: the stem is dark and gives when pressed; Leaves low on the plant are swollen, soft and slightly see-through; Dark, soft patches higher up the plant.
- What do Aloe vera's sources say about its soil moisture?
- RHS: Well-drained.
- What does this look like on a Aloe vera?

What this does not cover
This page orders a decision tree's results using a plant's sourced care. It has not seen your plant, its pot or its window, and two problems at once are common: that is the usual reason a confident answer turns out wrong. The questions in the diagnosis tool narrow it further than a list can.
