Mirror Bush · Coprosma repens

Why is my Mirror Bush growing so tall and thin?

A leggy Mirror Bush is usually reaching out for more light because it is not getting enough energy to stay compact. Check your plant's location to see if it needs a brighter spot.

Check these first

  1. Observe if the plant is leaning toward a window.
  2. Measure the distance between the leaves on the stems.
  3. Evaluate if the current spot provides bright, indirect light.

Likely causes

  1. Insufficient Light

    Most likely

    How to tell: The stems are long and thin with large gaps between the leaves. The plant will also lean heavily toward the nearest light source.

    What to do: Move your plant to a brighter location with more indirect light or some direct sun. If the plant is already very tall, you can prune the stems back to encourage bushier growth.

  2. Lack of Pruning

    Possible

    How to tell: This is less common for this plant, but usually happens when the plant grows naturally without any shaping. The branches become long and sparse over time.

    What to do: Prune the tips of the branches regularly during the growing season. This forces the plant to branch out and creates a fuller, more compact shape.

When to worry

Legginess is not a disease, so it is not a reason to worry about the plant's health. It is simply a sign that the plant wants a better environment to look its best.

Stopping it coming back

Provide plenty of bright light and prune the tips of the stems occasionally to keep the plant dense and tidy.

Questions people ask

Will the stems fill back in if I move it?
The existing bare stems will not grow new leaves, but moving it to better light will ensure new growth is compact. You can prune the long stems to encourage new, fuller growth.
Does this plant flower?
Mirror Bush does produce small, inconspicuous flowers, but they are not the main reason people grow it. It needs bright, consistent light to bloom, though it is rarely seen indoors.
