Dog rose · Rosa canina

Why is my Rosa canina growing leggy?

It is less common for a Dog rose to become leggy if it is getting enough light, so this usually means the plant is reaching for the sun. Check your light levels first to ensure your rose is getting full sun.

Check these first

  1. Observe how many hours of direct sun the plant gets.
  2. Check if nearby plants are shading your rose.
  3. Look for new growth to see if it is also stretching.

Likely causes

  1. Insufficient Light

    Most likely

    How to tell: The stems are long and thin with large gaps between the leaves.

    What to do: Move the rose to a location that receives full, direct sun for at least 6 to 8 hours a day. Prune back the long stems to encourage bushier growth.

  2. Lack of Pruning

    Possible

    How to tell: The plant has old, woody stems that have not been cut back in a long time.

    What to do: Prune the plant in late winter or early spring to remove old growth and stimulate new, compact branches. Cut back stems by one third to promote a fuller shape.

When to worry

If the plant is leaning heavily toward the light source, it is not getting enough sun. It is normal for roses to have some natural height as they mature.

Stopping it coming back

Provide full sun and prune annually to maintain a strong, compact structure.

Questions people ask

Will pruning make it bushier?
Yes, pruning signals the plant to send out new side shoots, which creates a denser, more attractive shape.
Does this plant flower?
Yes, Rosa canina produces beautiful flowers in the summer, but it needs full sun to bloom well. If it is leggy, it likely will not produce many flowers.
