Giant reed · Arundo donax

Why is my giant reed drooping?

Giant reed is a sturdy plant, so drooping is a clear sign it is unhappy with its environment. The most common cause is a lack of water, as this plant is a heavy drinker.

Check these first

  1. Touch the soil to see if it is dry.
  2. Check the pot to see if it is root bound.
  3. Ensure the plant is getting enough direct sunlight.

Likely causes

  1. Dehydration

    Most likely

    How to tell: The stems look limp and the leaves lose their upright posture. The soil will feel dry and dusty.

    What to do: Give the plant a thorough soaking immediately. Ensure the water reaches the entire root ball by watering until it drains out the bottom.

  2. Root stress

    Possible

    How to tell: The plant droops even when the soil is moist. This can happen if the roots are damaged or if the pot is too small.

    What to do: Check the roots for signs of decay. If the pot is crowded, transplant the reed into a larger container with fresh, moisture retentive soil.
