Controlling Invasive Sedum lineare (Stonecrop)

Sedum lineare is not truly invasive but forms dense mats. Its Achilles heel: it cannot tolerate foot traffic. Walk on it repeatedly to crush it. Alternatively, overwater to encourage crown rot (Pellicularis rolfsii) which thrives in rich, wet soil — sedum prefers dry, poor, alkaline soil. Stop liming. Seeds will germinate next spring; walk on seedlings to prevent establishment.
