Morning glory (Ipomoea tricolor) has become invasive in the West. When it's in your garden, you can eradicate it by 1.) digging/pulling or 2.) poisoning with Glyphosate, the active ingredient in herbicides like Round-Up. Problem is, this herbicide is non-selective; you don't want to kill your plants, too. One careful method to use: take a tip of the vine and place it into a plastic baggie, then spray directly into the bag. Please protect yourself with gloves, safety glasses and long sleeves.
