JULY WEED ALERT Knapweed, Pasture & Rangeland Invader! Knapweed threatens wildlife habitat, pastures and grasses. It causes signifi- cant loss of grazing forage and increases soil erosion. When flowering from early summer to fall, knapweed has upright branched stems from 1-5 ft. tall. It has medium green leaves with a silver gray cast that become smaller as they move up the flowering stem. Knapweed flower heads can be pink, purple or white, depending on the variety. Plants prefer full sun and well drained soils, growing well in loose gravel and disturbed areas. Do not compost plants with flowers. Pull, bag and place in garbage.
