Hello and thanks for using the Ask an Expert System.

I have not found any information suggesting that covering these plants with a tarp would kill them in 2 or 3 years. It may be worth a try.

The only current reliable method of killing lesser celanine is to use glyphosate.

You will find information on control methods in a fact sheet from the University of Washington, Control Options for Lesser Celandine
