SPIRAEA CONTINUED PEST and DISEASE MANAGEMENT Aphids and Spider Mites are the most prevalent insect pests associated with Spiraea. Scout and spray preventatively in April/May to prevent outbreaks in June and July when Spider Mites are more actively growing. We recommend implementing a good IPM program as well as early releases of Biological Control, to help aid in the control of insect populations. Spray with a regular fungicide rotation to control Powdery Mildew as heavy spray may cause leaf burn. SPECIAL NOTES When growing larger containers like 3 gallons, it is best to bulk them in the summer/fall the year before they are to be sold. This allows additional root growth, as well as additional pruning. Any surplus 1 gallon containers can easily be bumped into 3 gallon containers in the summer for next year's spring sales. The rates and chemicals listed are based on our southeast Michigan growing conditions, and are not recommended for nationwide application. Please adjust the rates and spray applications to your location and facility. 95
