- Test the water you are using for high mineral content.
Likely causes
Fertilizer burn
Most likelyHow to tell: The tips turn brown and brittle while the rest of the leaf looks healthy. This often happens shortly after feeding.
What to do: Stop all fertilizing immediately. King proteas are adapted to nutrient poor soil and rarely need extra food. If you must fertilize, use a phosphorus free product at half strength.
Hard water
PossibleHow to tell: A white crust forms on the soil surface or the rim of the pot. The leaf tips slowly turn brown over several weeks.
What to do: Switch to using rainwater or distilled water for your plant. If you must use tap water, let it sit out for 24 hours to allow chlorine to evaporate.

When to worry
Brown tips are usually cosmetic and not life threatening. You should only worry if the browning spreads rapidly toward the center of the leaves.
Stopping it coming back
Avoid using chemical fertilizers and stick to rainwater whenever possible.
