Elephant Ear · Colocasia

Why is my Colocasia growing tall and thin?

A leggy Elephant Ear is usually reaching for more light because it is not getting enough energy to grow compact. Check if your plant is sitting in a dark corner or too far from a window.

Check these first

  1. Move the plant closer to a bright window.
  2. Check if the plant is leaning toward the light.
  3. Assess if the plant has been in the same soil for over a year.

Likely causes

  1. Insufficient Light

    Most likely

    How to tell: The stems are very long and thin, and the plant leans heavily toward the nearest light source. The leaves may also be smaller than usual.

    What to do: Move the plant to a spot with brighter, indirect light. Rotate the pot a quarter turn every week to ensure all sides get even exposure.

  2. Lack of Fertilizer

    Possible

    How to tell: It is less common for this plant, but slow growth and thin stems can happen if the plant is hungry. The leaves might look pale or lose their deep color.

    What to do: Apply a balanced liquid fertilizer diluted to half strength once a month during the growing season. Do not fertilize during the winter months when growth naturally slows.

When to worry

It is normal for older leaves to eventually die off as the plant grows taller. If the new growth is consistently thin and weak, it is time to adjust the light.

Stopping it coming back

Provide consistent bright, indirect light throughout the year. Rotate your plant regularly to encourage sturdy, upright growth.

Questions people ask

Should I prune the leggy stems?
You can trim off the oldest, weakest stems at the base to tidy up the plant. This encourages the plant to put energy into new, stronger growth.
Will the stems get shorter if I move it?
The existing stems will not shrink, but new leaves will grow with shorter, sturdier stems. Over time, the plant will look much fuller.
