European dewberry · Rubus caesius

Why is my European dewberry growing so leggy?

It is less common for this plant to become leggy unless it is struggling to find enough light. Check the distance between your plant and its light source to see if it is stretching to reach the sun.

Check these first

  1. Observe the direction the plant is leaning.
  2. Measure the distance between leaf nodes on the canes.
  3. Check the light intensity in the current location.

Likely causes

  1. Low Light Levels

    Most likely

    How to tell: The canes are very long, thin, and pale with large gaps between the leaves. The plant leans heavily toward the nearest window or light source.

    What to do: Move the plant to a location with more direct sunlight. If you cannot provide more natural light, consider using a grow light for 10 to 12 hours a day.

  2. Excessive Nitrogen

    Possible

    How to tell: The plant grows very fast but the canes are weak and floppy. The foliage is a very dark green but lacks structural integrity.

    What to do: Switch to a balanced fertilizer with lower nitrogen content. Stop fertilizing during the winter months when the plant is not actively growing.

When to worry

Leggy growth is mostly an aesthetic issue, but it can lead to weak canes that break under their own weight. It is normal for the plant to grow longer canes during the peak of summer.

Stopping it coming back

Ensure the plant receives consistent, bright light and avoid over fertilizing with nitrogen rich products.

Questions people ask

Should I prune back leggy canes?
You can prune them to encourage bushier growth, but do not remove too much at once. Wait until the plant is in an active growth phase to prune.
Will these canes ever thicken up?
Once a cane has grown thin and leggy, it will not thicken significantly. Pruning it back and providing better light will encourage new, stronger growth.
