Check these first
- Assess the number of direct sun hours your plant gets daily.
- Inspect the base of the plant for woody, leafless stems.
- Check if the plant is leaning toward a window.
Likely causes
Insufficient Sunlight
Most likelyHow to tell: The stems stretch out and look thin with large gaps between the leaves. The plant will also lean heavily toward the nearest light source.
What to do: Move your lavender to a spot that receives at least 6 to 8 hours of direct sunlight daily. If you are growing it indoors, a south facing window is usually the only place bright enough to keep it happy.
Lack of Pruning
Most likelyHow to tell: The plant looks woody at the base with all the new growth happening only at the very tips of long branches. This happens naturally as the plant ages if it is not shaped.
What to do: Prune your lavender back by about one third after the main flowering flush finishes. Avoid cutting into the old, woody stems, as these rarely sprout new growth.

When to worry
It is normal for lavender to develop some woody stems as it matures over several years. You should only worry if the plant is falling over or looks extremely sparse after a full season of growth.
Stopping it coming back
Keep your lavender in the brightest spot available and give it a light trim every year after it blooms to encourage dense, bushy growth.
