Does this plant need fertilizer?

Very little. Proteas are adapted to nutrient poor soils and can be harmed by standard fertilizers.

Can I grow it indoors?

It is very difficult. They require intense, direct sunlight that most indoor windows cannot provide.

Likely causes

Insufficient light
Most likely
How to tell: The plant looks healthy but produces only leaves. It may start to stretch toward the nearest light source.
What to do: Move the plant to a location where it receives full, direct sun for at least 6 to 8 hours a day. Outdoors is usually best for this species.
Improper fertilizer
Possible
How to tell: The plant is growing very fast with lots of leaves but no buds. This often happens if you use a high nitrogen fertilizer.
