Rhipsalis

Why is my Mistletoe cactus growing long and thin?

A leggy Rhipsalis is usually reaching out for more light. When it does not get enough brightness, the new growth becomes stretched and weak.

Check these first

  1. Assess the light levels in the current location.
  2. Check if the plant is leaning toward a window.
  3. Look for signs of new growth that is pale or thin.

Likely causes

  1. Insufficient light

    Most likely

    How to tell: The stems are growing very long with large gaps between segments. The plant looks sparse rather than full and bushy.

    What to do: Move the plant to a spot with bright indirect light, such as near an east or north facing window. You can prune back the long, thin stems to encourage fuller growth.

  2. Lack of pruning

    Possible

    How to tell: The plant is healthy but has long, trailing stems that have lost their shape. It is not necessarily weak, just overgrown.

    What to do: Trim the ends of the longest stems to encourage branching. This will make the plant look much fuller over time.

When to worry

It is not a health emergency, but it does mean the plant is unhappy with its environment. It is normal for the plant to trail, but it should not look thin or pale.

Stopping it coming back

Keep your Mistletoe cactus in a bright spot year round. Rotate the pot every few weeks so all sides get equal light.

Questions people ask

Will the thin stems thicken up?
No, the existing thin stems will stay that way. You should prune them off to encourage new, stronger growth.
Can I put it in direct sun?
Avoid harsh, direct midday sun as it can burn the stems. Bright indirect light is perfect for keeping it compact and healthy.
