|I have a large bed of Vinca ground cover about 50 years old. It is 100 ft by 10 ft. There is an invasive weed that is taking over the Vinca. It blooms in June and the flower looks like Queen Ann's Lace. The roots are just horrible on this plant, very tight and impossible to dig.
My question: is there anything I can spray on this vinca bed that will kill the weed and not the Vinca? My house is an historic 1772 house and I would sure hate to lose this wonderful ground cover.
Any help you can give me is much appreciated.
PS I have a scan of the weed to e-mail you if you send me your e-mail address.
|I am unable to accept a scan, but thank you. Perhaps the most efficient approach would be to hand wipe the foliage of this plant with herbicide containing glyphosate being careful to avoid it contacting the vinca. This is a nonselective herbicide and would damage any vinca it came in contact with.
An alternative would be to dig and preserve some of the vinca, then spray the entire bed until you are sure the weed has been eradicated. Then, replant the vinca.
Whichever method, be sure to read and carefully follow all of the label instructions for best results.
