We have the wood violet on our lawn which are continuously spreading. What can I do to stop it? Thank you in advance for your advice.

Frequent lawn aerating is a basic mechanical disruption of the horned violet but you must stay on the ball.
Another variation is a herbicide for lawn weeds. For example, the “Lawn Weed Killer Banvel-M” (by Compo).
