What product is best for killing ground elder in the garden?
Black plastic sheeting, hoes and shovels, matches, pruners, and systemic weed killers are the best products for killing ground elder in the garden. The weed in question (Aeropodium podagraria) can be controlled by digging up roots, hoe-cutting foliage (which is edible between February and June as ground up seasoning or pasta ingredients), and treating with systemic weed killers. It also may be controlled by a coordinated approach of controlled burning, extreme trimming, and plastic sheeting, from which the ground will be solarized, the weed will die, and the topsoil will need to be replaced to prevent ground elder returns.
