Check these first
- Observe the amount of light reaching the plant during the day.
- Check if the stems are leaning heavily toward a nearby window.
- Inspect the plant for any signs of new growth near the base.
Likely causes
Insufficient light
Most likelyHow to tell: The stems stretch out with large gaps between the leaves as the plant reaches for a light source. You might also notice the foliage becoming paler than usual.
What to do: Move your plant to a brighter location that receives full sun or partial shade. If you are growing it indoors, place it directly in a south or west facing window.
Lack of pruning
PossibleHow to tell: The plant looks healthy but has long, woody stems that have lost their bushy shape over time. This is a natural aging process for older shrubs.
What to do: Trim back the long stems by one third after the plant finishes blooming. This encourages new, denser growth to sprout from the base.

When to worry
It is not a cause for alarm if your plant is just growing naturally, but you should worry if the stems become so weak they cannot support themselves. Minor stretching is normal as the plant ages.
Stopping it coming back
Keep your Bog rosemary in a bright spot and give it a light trim once a year to maintain a compact shape.

Questions people ask
- Can I fix leggy stems by just moving the plant?
- Moving it to better light will stop the stretching, but it will not make the existing long stems shorter. You will need to prune those back to encourage a bushier look.
- Will my Bog rosemary flower if it is leggy?
- A leggy plant often struggles to produce flowers because it is not getting enough energy from the sun. Improving the light levels is the best way to help it bloom again.
