Tom from Milwaukee, Wi writes

Frequency of Fertilome Tree and Shrub Systemic Insect Drench application for emerald ash borer? Once or twice a year?

Several of the Q&As mention twice a year application (fall and spring). The label states to not make more than one application per year, the single application preferably in the fall. Is the recommendation to control emerald ash borer to apply once or twice a year?

Answer:

Fertilome Tree and Shrub Systemic Insect Drench label states one application protects for 12 months. We apologize for any confusion.
