Identify Poison Hemlock

Baby poison hemlock plants look a lot like leather leaf ferns, as they grow and mature, they shoot up to 5, 6 7,8 feet or taller!

They have a large umbrella-like cluster of white flowers, and tall green and purple-colored stems.

The musty odor is usually prominent in warmer weather. I would not recommend smelling the plant to see if it is musty or not. I did this once and had diarrhea for 3 days.

Chances are if you suspect it is Poison Hemlock, it probably is.

How do you get rid of poison hemlock?

– If you’re lucky enough to find it growing in its natural habitat, you should leave it alone.

– To get rid of poison hemlock in a small area within your own yard, safely dig it up as much as possible. Add to a plastic bag, tie up and take to dump. Apply 3 to 4 inches of USDA Certified Organic Compost and/or Soil onto of the area. You will need to apply to surrounding grounds because hemlock will sprout up everywhere within a close range of an existing plant.

– You can cover the entire ground and area with a thick black plastic. Lay large rocks or heavy objects on the plastic to keep it as close to the ground as possible.

– Leave the plastic cover for at least a week.

– Then apply the USDA Certified Organic Soil or Compost.
