Check these first
- Measure the hours of direct sunlight the vine receives daily.
- Observe the distance between leaf nodes on the main stems.
- Check your recent fertilization schedule for high nitrogen levels.
Likely causes
Insufficient Sunlight
Most likelyHow to tell: The vine has long spaces between leaves and the stems look weak or pale. It is reaching toward the nearest light source.
What to do: Move the vine to a spot that receives full sun for at least 8 hours a day. If it is in a container, relocate it to a south facing area.
Excessive Nitrogen Fertilizer
PossibleHow to tell: The plant grows very fast with soft, green stems but produces few fruits. This happens when the soil is too rich in nitrogen.
What to do: Stop using high nitrogen fertilizers during the growing season. Switch to a balanced fertilizer with lower nitrogen content to encourage structural strength.

When to worry
It is normal for vines to grow long during the peak of summer, but if the stems are too weak to support themselves, you should intervene. If the vine is not getting at least 6 to 8 hours of sun, it will struggle to thrive.
Stopping it coming back
Provide full sun from the start and prune the vine annually to maintain a strong, compact structure.

Questions people ask
- Can I prune back the leggy stems?
- Yes, pruning helps the plant redirect energy into stronger growth. Cut back the long, weak stems during the dormant winter season.
- Will my vine produce fruit if it is leggy?
- Leggy vines often produce less fruit because they lack the energy and structure to support a harvest. Improving light exposure is the best way to boost fruit production.
