"Milkweed does contain toxins that can be harmful to pets, livestock and people. The milky sap for which it gets its name leaks out from the stem or leaves. This sap contains toxins called cardiac glycosides or cardenolides, which are toxic to animals if consumed in large quantities.

The good news? Milkweed does NOT taste good.

“Animals usually do not eat milkweed unless good forage is scarce or under conditions where plants freeze, etc. “ — USDA

The myth here, is that you shouldn’t plant milkweed at all. The truth is…most animals won’t eat it because of the taste, and here are some tips for handling milkweed if you’re hesitant.

Being careful and aware goes a long way.

  1. Wash your hands and use gardening gloves like you would any other plant.
  2. Be careful to not include it in the hay of grazing animals and make sure there is always plenty of other food for them to forage.
  3. Know that your pets will likely avoid it, but if you’re nervous, research the milkweed species you plant to see toxicity levels.
  4. Take steps to prevent accidental ingestion, such as instructing children that the plant is poisonous and to avoid any contact with their eyes after touching the plant.
