Check these first
- Assess the number of hours of direct sunlight your plant receives daily.
- Observe if the plant is leaning toward a specific light source.
- Check if the stems have been pruned in the last year.
Likely causes
Insufficient Light
Most likelyHow to tell: The stems are long and thin with large gaps between the leaves. The plant leans heavily toward the nearest window.
What to do: Move your eucalyptus to a spot that gets at least 6 to 8 hours of direct sun every day. If you cannot provide enough natural light, place it under a high output grow light for 12 hours daily.
Lack of Pruning
Most likelyHow to tell: The plant is tall and sparse but otherwise appears healthy. It has not been trimmed back in a long time.
What to do: Prune the top stems back by 2 to 4 inches to encourage side branching. Do this in the spring or early summer when the plant is actively growing.

When to worry
It is not a medical emergency, but a leggy plant will eventually become top heavy and unstable. It is normal for young eucalyptus to grow quickly, but they should remain dense if given enough light.
Stopping it coming back
Keep your eucalyptus in the brightest spot you have and prune it lightly once a year to maintain a compact shape.

Questions people ask
- Can I fix a leggy eucalyptus by just moving it?
- Moving it to better light will stop the new growth from being leggy, but the existing long stems will not shrink. You will need to prune those long stems to help the plant look fuller again.
- Does my eucalyptus need fertilizer to stop being leggy?
- No, fertilizer will actually make a leggy plant grow faster and even weaker. Focus on increasing the light exposure first.
