I want to eliminate, completely, an area of about 250 sq ft and re-plant with different plant/tree.
Bonide Grass Beater Over-The-Top Grass Killer Concentrate will not kill Hypericum. Please contact the Master Gardener in your area for the best product to eliminate Hypericum. You can contact the Master Gardener through your Extension Office.
