My husband applied this about a month ago. We have a scale problem on our crape myrtle. I'm concerned because I read you need to apply May to July for effectiveness with scale. Can we apply it again?
Fertilome Tree and Shrub Systemic Insect Drench is meant to be applied once a year. This product has enough of the active ingredient to last over the year to continue killing insects.
