Jade Plant · Crassula ovata

Why are there white fuzzy spots on my jade plant?

Those little white cottony patches are almost certainly mealybugs. They love to hide in the tight spaces where leaves meet the stem to feed on your plant's sap.

Check these first

  1. Inspect the crevices where leaves attach to the main stem.
  2. Check the undersides of the leaves for sticky residue.
  3. Look for small white insects crawling on the soil surface.

Likely causes

  1. Mealybug infestation

    Most likely

    How to tell: You will see white, waxy, or cottony masses tucked into the leaf axils. The leaves might also look sticky or start to drop.

    What to do: Dip a cotton swab in rubbing alcohol and touch it directly to each bug to kill it instantly. Follow up by spraying the entire plant with a mixture of water and a few drops of mild dish soap once a week for a month.

  2. Scale insects

    Possible

    How to tell: These look like small, hard brown bumps on the stems or leaves that do not move. They act like tiny shields protecting the insect underneath.

    What to do: Gently scrape the bumps off with your fingernail or a soft toothbrush. Wipe the area down with a cloth soaked in rubbing alcohol to remove any remaining residue.

When to worry

If the infestation covers the entire plant and leaves are falling off rapidly, it is a serious situation. A few isolated bugs are easy to manage if caught early.

Stopping it coming back

Keep your jade plant in a spot with good airflow and inspect it every time you water. Always quarantine new plants for two weeks before placing them near your jade.

Questions people ask

Will these bugs kill my jade?
If left untreated, they can weaken the plant significantly and cause leaf drop. However, they are usually easy to manage if you act as soon as you see them.
Should I use a systemic pesticide?
It is usually unnecessary for jade plants. Manual removal with alcohol is safer and very effective for this species.
