Check these first
- Observe how many hours of direct or bright indirect light the plant receives daily.
- Check if the plant is leaning toward a specific light source.
- Compare the width of the new growth to the older sections of the stem.
Likely causes
Insufficient Light
Most likelyHow to tell: The new growth is thin, pale, and spaced far apart along the stem. The plant leans heavily toward the nearest window.
What to do: Move the plant to a spot that receives bright, indirect light or a few hours of direct morning sun. Rotate the pot every two weeks to ensure even growth on all sides.
Seasonal Growth
Most likelyHow to tell: The plant grows rapidly during the summer months but looks thin compared to its base. This is a natural response to the longer days.
What to do: Provide as much bright light as possible during the growing season. You can prune the top of the stem if you want to encourage branching, but wear gloves to protect against the milky sap.

When to worry
Legginess is rarely a health emergency but it does make the plant top heavy. It is normal for the plant to stretch slightly during the darker winter months.
Stopping it coming back
Keep your plant in the brightest location available in your home. Rotate the pot regularly to keep the stem growing straight.

Questions people ask
- Can I prune a leggy African milk tree?
- Yes, you can cut the top off to encourage branching. Be very careful as the white sap is toxic and can irritate your skin and eyes.
- Will it ever get thick again?
- The thin part will not thicken, but new branches that grow in better light will be more robust. Proper light is the only way to prevent further stretching.
