Check these first
- Feel the soil to see if it is soggy.
- Check the drainage holes for blockages.
- Observe if the plant was recently moved.
Likely causes
Overwatering
Most likelyHow to tell: The leaves may turn black or soft before falling off, and the soil feels constantly damp. This plant hates sitting in wet, heavy soil.
What to do: Stop watering immediately and check if the soil is draining well. If the soil is soggy, repot the plant into a fast draining mix with plenty of pumice or perlite. Only water again when the top 3 inches of soil are dry.
Sudden Light Change
PossibleHow to tell: Leaves drop shortly after you move the plant to a new location with less sun. King Proteas need intense, direct light to thrive.
What to do: Move the plant back to a spot with full, direct sun. Ensure it gets at least 6 to 8 hours of bright light daily. Avoid moving it again once it starts to recover.

When to worry
It is normal for the oldest, lowest leaves to drop occasionally as the plant grows. Worry if you see multiple leaves falling at once or if the stems look shriveled.
Stopping it coming back
Ensure your potting mix is very gritty and never let the pot sit in a saucer of water.

Questions people ask
- Will my plant grow new leaves where they fell off?
- Usually no, as King Proteas do not branch out easily from bare stems. The plant will likely focus its energy on new growth at the tips.
- Is it normal for leaves to drop in winter?
- No, this plant is evergreen and should keep its foliage year round. Leaf drop in winter is a sign of too little light or too much water.
