Answer 1

Morning glories put out a terrific amount of seed so if you've had them for more than a year, you'll have a near continuous eruption of new plants for several years to come. Seeds aren't affected by herbicide. You might try a pre-emergent which keeps many seeds from germinating. On a metal fence, they can be hit with a small weeding torch. Other than that, your best friend is a hoe or hand-held weeder.
