- Inspect the base of the plant to see if old wood is crowding out new growth.
Likely causes
Insufficient Light
Most likelyHow to tell: The stems are stretching out with large gaps between the leaves as they reach for a light source. The plant may also lean heavily toward the nearest window or sun patch.
What to do: Move your redcurrant to a spot that receives at least 6 to 8 hours of direct sunlight daily. If you are growing it indoors, place it right in a south facing window or use a high output grow light.
Lack of Pruning
PossibleHow to tell: The bush looks sparse and spindly because old, unproductive wood is taking up energy. You will notice long, bare branches that do not produce much fruit or foliage.
What to do: Prune your redcurrant in late winter while it is dormant. Remove about one third of the oldest, thickest branches at the base to encourage new, vigorous growth from the center.

When to worry
It is only a concern if the plant stops producing fruit or looks visibly weak. Some stretching is normal if the plant is just waking up from its winter dormancy.
Stopping it coming back
Ensure your redcurrant gets plenty of full sun and perform a consistent pruning routine every winter to keep the structure compact.

Questions people ask
- Can I prune my redcurrant in the summer?
- It is best to wait until winter when the plant is dormant. Pruning during the growing season can stress the plant and reduce your fruit harvest.
- Will my leggy redcurrant fill back in?
- It will not fill in on the bare parts of the old stems. However, proper pruning will stimulate new, healthy growth that will make the bush look full again over time.
