Wineberry · Rubus phoenicolasius

Why are my wineberry canes growing so leggy?

It is less common for wineberries to become leggy unless they are struggling to find enough light. This usually happens when the plant is reaching for the sun in a shaded location. Check your light exposure first.

Check these first

  1. Verify that the plant is receiving at least 6 to 8 hours of direct sun.
  2. Check if the plant is crowded by other shrubs or trees.
  3. Review your recent fertilizing habits.

Likely causes

  1. Lack of Direct Sunlight

    Most likely

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

    What to do: Relocate the plant to a spot with full sun. If you cannot move it, prune back the surrounding vegetation to clear the path for light.

  2. Excessive Nitrogen Fertilizer

    Possible

    How to tell: The plant produces very long, soft, and floppy canes that struggle to support their own weight. This often happens after applying too much high nitrogen fertilizer.

    What to do: Stop using high nitrogen fertilizers during the growing season. Switch to a balanced fertilizer and apply it only once in early spring.

When to worry

It is normal for wineberries to grow long, arching canes as they mature. Worry only if the canes are weak, thin, and unable to hold themselves up.

Stopping it coming back

Provide adequate sunlight and avoid over fertilizing to encourage strong, sturdy cane growth.

Questions people ask

Should I stake my wineberry?
Wineberries have a natural arching habit, but you can use a trellis to keep them tidy. Staking can help if the canes are heavy with fruit.
Can I prune leggy canes?
Yes, you can trim back the tips of the canes to encourage branching. Just be careful not to remove too much of the fruiting wood.
