Acorns – Controlling Sprouts and Growth
Q: We had a lot of acorns falling into our lawn this year. Some have begun to take root. Is there something I can do to prevent the others from rooting?
A: There’s nothing you can do except pull them by hand or spray them with a broadleaf weed killer (click for sources) as they germinate for the next few weeks.
Regular mowing will also control the sprouts and they will gradually deteriorate.
