Mandarin orange · Citrus reticulata

Why is my mandarin orange tree looking leggy?

It is less common for a healthy mandarin orange to look leggy, as they naturally grow into dense, rounded shapes. This usually happens when the tree is reaching desperately for more light. Check your light levels first.

Check these first

  1. Observe how many hours of direct sun the tree receives daily.
  2. Check if the tree is leaning toward a window.
  3. Inspect the branches to see if they are thin and weak.

Likely causes

  1. Insufficient Light

    Most likely

    How to tell: The branches are long and thin with large gaps between the leaves. The tree looks stretched out rather than full and bushy.

    What to do: Move your tree to a spot that gets at least 8 hours of direct sunlight every day. If you are growing indoors, place it in a south facing window or use a high intensity grow light.

  2. Improper Pruning

    Possible

    How to tell: The tree has a few long, dominant branches that are growing straight up or out without any side branching. This often happens if the tips were never pinched back.

    What to do: Prune the long, leggy branches back to a leaf node to encourage lateral growth. Do this in late winter or early spring before the new growth flush begins.

When to worry

Worry if the tree stops producing new leaves or if the branches become too weak to support their own weight. It is normal for a young tree to have a few longer shoots while it is establishing its structure.

Stopping it coming back

Ensure your tree gets full sun all year round and pinch back the tips of new growth to encourage a compact, bushy shape.

Questions people ask

Can I fix a leggy tree by just moving it?
Moving it to better light will stop the legginess from getting worse. However, you will likely need to prune the existing long branches to help the tree fill out again.
Will my mandarin orange bloom if it is leggy?
A leggy tree often lacks the energy and light exposure required to produce flowers. Focus on improving the light and pruning to help it reach a healthy state for blooming.
