Here’s a clever way to get rid of twining briars and nuisance vines without damaging your shrubs. Buy a few floral water tubes (available at floral supply companies and nurseries) or just reuse the tubes that come with individual roses. Fill the floral tube with a little herbicide (like Roundup) and replace the rubber cap to keep out pets and rain. Stick the tube in the ground and then stick the tip of the vine into the tube. The vine will “drink up” the weed killer down to its roots and die within a few days. — Judi Collins. Plus: How to eliminate weeds from your lawn.
