UMass Extension Landscape Message August 23, 2013

"Japanese knotweed is just beginning to flower, or will flower soon, and now is the time to manage this invasive plant. Use a 2% spray solution of glyphosate sprayed to the initiation of spray drip. Do not use herbicide formulations that contain diquat (RewardTM) or tank-mix pelargonic acid (ScytheTM) with the glyphosate. Diquat and pelagonic acid are contact herbicides and have the potential to decrease the efficacy of glyphosate. In areas near water, a formulation of glyphosate that is labeled for theses areas should be used. Non-chemical products containing clove oil, citric acid, acetic acid or orange extract will not effectively control Japanese knotweed."

And from the Cape Cod Region report:

"Crepe Myrtle, an unusual large shrub/small tree for the Cape, is in full bloom. There are hardy cultivars of this more Southern ornamental that should be planted more often here to provide late summer color."
