One upside of spotted knapweed is that it does provide a pollen and nectar source when there aren’t many other plants flowering. Local honey growers have relied on this flowering plant in years when weather events have drastically reduced or shortened flowering times on other trees, flowers and shrubs. With nectar that has a bitter taste, however, some suggest that quality of honey is lowered. So replacing spotted knapweed with brassicas and buckwheat may have even more merit.
Finally, probably the most important management practice with spotted knapweed is prevention. Since this invasive weed spreads by seed, growers need to be extremely careful that they are not contaminating clean fields. Hay equipment and vehicles can easily transport seed from infested to clean fields. Growers should manage their cutting rotation of fields and clean equipment after harvesting infested fields. If an infestation starts in a field, addressing the problem quickly can save producers the money that a total field renovation will cost.
