Crassula ovata, commonly known as jade plant, lucky plant, money plant or money tree, is a succulent plant with small pink or white flowers that is native to the KwaZulu-Natal and Eastern Cape provinces of South Africa, and Mozambique; it is common as a houseplant worldwide. Much of its popularity stems from the low levels of care needed; the jade plant requires little water and can survive in most indoor conditions. Wikipedia, CC BY-SA 4.0

Native range: SE. Mozambique to SE. Cape Prov. (subtropical). Also sold as Baby Jade, Chinese rubber plant, Dwarf rubber plant, friendship tree, jade tree and Japanese rubber plant.

Watering
Water moderately once the soil is dry, and less from fall to late winter. Overwatering can cause leaf fall and root rot.
NC State Extension · read 13 September 2026
During growth in spring and summer, water enough to keep lightly moist; during winter dormancy, water very sparingly.

How this shows up on a Jade plant

Swollen, darkening leaves that come away at a touch

Soft, discoloured tissue appears where the leaves join the stem of the jade plant, 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: Firm and wrinkled is thirst; soft and swollen is the opposite. The two look similar from across a room and feel nothing alike.

Possible causes, likeliest first for a Jade plant

  1. Most likely too much water for a plant that stores its own

    Ranked higher because Jade plant's recorded problems point this way.

    Jade plant 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.

    • Well-drained RHS · read 11 September 2026
    • Loam; pH Acid or Alkaline or Neutral RHS · read 11 September 2026

    Why: A jade plant 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.

  2. 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.

    Check this with the questions

  3. Most likely cold

    • H2 — 1–5°C RHS · read 11 September 2026

    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 jade plant.
    • Leave damaged leaves until new growth appears, then remove the worst of them.

    What would settle it: Where the jade plant 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.

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.
