Likely causes
Insufficient Light
Most likelyHow to tell: The stems grow long and thin with large gaps between the leaves as the plant stretches toward a light source. You might also notice the foliage losing its signature silvery sheen.
What to do: Move your Silver Tree to a spot that receives full, direct sun for at least 6 to 8 hours a day. If you are growing it indoors, place it directly in front of a south facing window.
Excessive Nitrogen
PossibleHow to tell: The plant produces rapid, weak growth that cannot support its own weight. This often happens if you use a fertilizer meant for general garden plants instead of one formulated for Proteaceae.
What to do: Stop all fertilization immediately. Only use fertilizers specifically labeled for Proteaceae or phosphorus sensitive plants, and apply them at half strength once in the spring.

When to worry
You should worry if the stems become so weak they start to bend or break under their own weight. It is normal for the plant to have a slightly open structure as it matures into a tree.
Stopping it coming back
Keep your Silver Tree in a high light environment and avoid using high nitrogen fertilizers to ensure compact, healthy growth.
