Pocket Botanist
Check these first
- Measure the hours of direct sunlight the plant receives daily.
- Observe if the plant is leaning toward a window or wall.
- Check if you have been adding fertilizer to the soil.
Likely causes
Insufficient Sunlight
Most likelyHow to tell: The stems are long and thin with large gaps between the leaves. The plant leans heavily toward the nearest light source.
What to do: Move the plant to a location that receives full, direct sun for at least 6 to 8 hours a day. If it is indoors, a south facing window is the only suitable spot.
Excessive Fertilizer
PossibleHow to tell: The plant produces rapid, weak growth that cannot support its own weight. The foliage looks lush but lacks the typical silvery desert hue.
What to do: Stop all fertilizing immediately. Brittlebush thrives in poor, rocky soils and does not require supplemental nutrients.

When to worry
Legginess is not fatal, but it makes the plant prone to snapping in high winds. It is normal for the plant to lose some density in the winter months.
Stopping it coming back
Keep your Brittlebush in full sun year round. Avoid using fertilizers, as they encourage unnatural, rapid growth.
