Check these first
- Observe how many hours of direct sun the plant receives.
- Check if the stems are stretching toward the nearest light source.
- Inspect the base of the plant for new growth.
Likely causes
Insufficient Light
Most likelyHow to tell: The stems are long and thin with large gaps between the leaves. The plant looks sparse rather than full.
What to do: Move your jasmine to a spot that gets at least 6 hours of bright light daily. If you are growing it indoors, place it directly in a south or west facing window.
Lack of Pruning
PossibleHow to tell: The plant is healthy but has long, unruly vines that do not branch out. This is common as the plant matures.
What to do: Trim back the long stems by one third after the plant finishes blooming. This encourages the plant to grow bushy and produce more flowers next season.

When to worry
It is not a health emergency, but it will continue to look thin if the light is not improved. Pruning is a normal part of keeping this plant tidy.
Stopping it coming back
Keep your jasmine in a bright location and prune it lightly once a year to maintain a compact shape.

- Will my jasmine grow back if I cut it?
- Yes, jasmine responds very well to pruning. It will grow back thicker and healthier if you trim it back after flowering.
- Can I grow jasmine in a dark corner?
