Sugarbush · Protea

Why is my Protea growing tall and leggy?

It is less common for a Protea to become leggy unless it is starved for light, as these plants are adapted to harsh, sunny environments. Check the amount of direct sunlight your plant receives each day.

Check these first

  1. Move the plant to a location with more direct sun.
  2. Assess if the plant is getting at least 6 hours of full sun.
  3. Look for signs of new growth nodes along the stems.

Likely causes

  1. Insufficient light

    Most likely

    How to tell: The stems stretch out with large gaps between the leaves as the plant searches for more sun. The foliage may also look paler than usual.

    What to do: Move the plant to a spot that receives full, direct sun for at least 6 to 8 hours a day. If you are growing it indoors, a south-facing window is usually the only place bright enough.

  2. Lack of pruning

    Possible

    How to tell: The plant has long, woody branches that have not been trimmed in several seasons. The growth becomes sparse and top-heavy.

    What to do: Prune the plant back by one third after it finishes flowering to encourage bushier growth. Always cut just above a set of healthy leaves to stimulate new buds.

When to worry

It is a concern if the plant is leaning heavily toward a light source or looks weak. It is normal for a mature Protea to have a woody, architectural base as it ages.

Stopping it coming back

Provide maximum sun exposure and prune annually after the flowering cycle to maintain a compact shape.

Questions people ask

Can I prune a leggy Protea at any time?
No, you should only prune right after the flowering season. Pruning at the wrong time can remove the buds for the next year.
Does my Protea need fertilizer to stop it from being leggy?
No, fertilizer will not fix legginess caused by low light. In fact, Proteas are sensitive to phosphorus and require a low-phosphorus fertilizer specifically formulated for native plants.
