There are typically three pollen seasons in Minnesota, with some overlap of pollen types. Tree pollen is present from early April until the end of May. Grass pollen is present from early June to mid-July. Weed pollen is present from mid June until a hard frost occurs. Ragweed (one of the more allergenic weeds in the area) typically pollinates from early August through mid October.
