Polka dot begonia · Begonia maculata

Why is my Polka dot begonia looking so leggy?

A leggy Polka dot begonia is usually reaching out for more light. When it does not get enough brightness, it stretches its stems to find a better spot.

Check these first

  1. Evaluate the light levels in the current location.
  2. Rotate the pot every time you water to ensure even growth.
  3. Check if the stems are healthy and firm.

Likely causes

  1. Insufficient Light

    Most likely

    How to tell: The stems grow long with large gaps between the leaves. The plant leans heavily toward the nearest window.

    What to do: Move your plant to a spot with bright indirect light. If you do not have a bright window, consider adding a grow light to provide the intensity it needs.

  2. Lack of Pruning

    Possible

    How to tell: The plant is tall and sparse even though it is getting decent light. It has not been trimmed in a long time.

    What to do: Prune the stems back to encourage bushier growth. Cut just above a leaf node to stimulate new branches to grow from that point.

When to worry

It is normal for this plant to grow tall over time, but if it looks weak or cannot support its own weight, it needs more light or a trim.

Stopping it coming back

Rotate your plant regularly and prune it back in the spring to maintain a compact shape.

Questions people ask

Can I propagate the cuttings from pruning?
Absolutely, you can root the stem cuttings in water. Once they have roots, you can plant them back into the main pot to make it look fuller.
Will the stems fill back in?
The bare parts of the stem will not grow new leaves, but pruning will encourage new growth that fills out the plant.
