redroot pigweed · Amaranthus retroflexus

Why are there bugs on my redroot pigweed?

It is less common for this plant to have pest issues, but aphids or spider mites can occasionally show up if the plant is stressed. Check the undersides of the leaves first to see if you can spot any tiny insects or webbing.

Check these first

  1. Inspect the undersides of the leaves for small insects.
  2. Look for fine webbing near the joints of the stems.
  3. Check if the new growth looks sticky or distorted.

Likely causes

  1. Aphids

    Possible

    How to tell: You will see clusters of tiny green or black insects on the new growth or stems. They often cause the leaves to look slightly distorted or sticky.

    What to do: Spray the plant with a gentle stream of water to knock them off. If they persist, apply a mild insecticidal soap every 5 to 7 days until they are gone.

  2. Spider Mites

    Possible

    How to tell: Look for fine, silky webbing between the stems and leaves. The foliage may also start to look speckled or pale.

    What to do: Increase the humidity around the plant and wipe the leaves down with a damp cloth. Use neem oil once a week for 2 weeks to clear up a heavy infestation.
