Variegated ornamental grass · Glyceria maxima 'Variegata'

Why is my Variegated Manna Grass looking leggy?

Leggy growth happens when your grass is reaching for more light than it is currently getting. Check your light levels to ensure it is getting enough bright, indirect sun.

Check these first

  1. Observe the direction the plant is leaning.
  2. Measure the light intensity in the current location.
  3. Check if the plant has been fertilized recently.

Likely causes

  1. Insufficient light

    Most likely

    How to tell: The stems are long, thin, and leaning heavily toward the nearest light source.

    What to do: Move the plant to a spot with brighter, indirect light. If indoors, a south or west facing window is ideal.

  2. Excessive nitrogen

    Possible

    How to tell: The plant is growing very fast but the stems are weak and floppy.

    What to do: Reduce the frequency of fertilization. Only feed the plant once or twice during the growing season with a balanced fertilizer.

When to worry

Some stretching is normal during the low light of winter. Worry if the stems become so weak they cannot stand up on their own.

Stopping it coming back

Provide consistent bright, indirect light throughout the year. Rotate the pot occasionally to ensure even growth.
