What to do: Move the plant to the sunniest spot you have. It needs full, direct sun to produce the energy required for those massive blooms.
Wrong fertilizer
PossibleHow to tell: The plant is growing lush green leaves but shows no signs of buds. You might be using a high nitrogen fertilizer.
What to do: Stop using high nitrogen fertilizers immediately. If you need to feed, use a specialized low phosphorus fertilizer designed for proteas.

When to worry
It is normal for young plants to take 3 to 5 years to bloom from seed. If your plant is mature and still not blooming, it is likely a light issue.
Stopping it coming back
Provide maximum sun exposure and avoid overfeeding to encourage natural blooming cycles.
