How Do I Get Rid Of Liverwort? Is There Something Simple And/or Natural I’m Overlooking To Get Rid Of This Stuff?

Question

I live in zone 7, Sammamish, WA. I’m certain I adopted it from a nursery plant. It likes the shade best but is even growing in sunny spots this spring.

Answer 1

Liverworts are considered an aquatic plant. Your soil must be very moist to have a problem with them. They spread by spores, rather than seeds or creeping rhizomes. I wonder if you meant lungwort, which is a shade plant that can spread rapidly. If hand pulling is not an option, you can smother them with a clear plastic covering for several weeks, if there are no other plants in the area you want to keep. The plastic will kill everything beneath it. Boiling water is good for killing annuals, and to a lesser degree on perennials.

Failing that, if the plants are in your grass, you may want to try a selective herbicide. If they are isolated, you can use a non-selective herbicide to eradicate them.
