• Woerner recommends annual pH testing and adjustment in accordance with soil test recommendations.
• Any suitable organic-based fertilizer may be substituted for any single scheduled application.
• Routinely scheduled application of insecticides, fungicides, and herbicides are recommended to aid in the prevention of weeds, insects, and disease.
• Product combinations of fertilizer and weed control may be utilized but Woerner recommends separate applications to target specific issues as they occur.
• Chinch Bugs are typically active during the months of June thru Sept. Monitor and apply appropriate pesticides as the label recommends.
