Every fact cited
Soil-applied treatments are most effective when applied in spring as trees begin active growth. In the Black Hills climate around Rapid City, that window can run slightly different than the eastern part of the state depending on elevation and that year’s spring weather — a local arborist can confirm the right timing rather than going by a generic statewide date.
