Why is my Giant ragweed drooping?

Giant ragweed is a thirsty plant that grows very fast. If it starts to wilt, it is almost always telling you it needs more water immediately.

Check these first

  1. Check the soil moisture by sticking your finger two inches into the dirt.
  2. Observe if the plant recovers after the sun goes down.
  3. Feel the leaves to see if they are brittle or soft.

Likely causes

  1. Dehydration

    Most likely

    How to tell: The entire plant looks limp and the soil feels dry to the touch several inches down.

    What to do: Give the plant a deep soak right away. Ensure the water reaches at least 6 inches into the soil to hydrate the deep root system.

  2. Heat stress

    Possible

    How to tell: The plant droops during the hottest part of the afternoon but perks up again at night.

    What to do: Apply a thick layer of mulch around the base to keep the roots cool. If the plant is in a container, move it to a spot with slightly less intense afternoon sun.
