Answer: Morning glories are annual vines in cold weather areas, meaning they freeze to death each winter. If the vine is truly morning glory, then you are seeing new seedlings emerge and grow each year. You can prevent them from germinating by disturbing the area in late spring as the soil begins to warm and then smothering them with a layer of newspaper covered by a thick layer of mulch such as shredded bark. This should do the trick, although digging in the area may bring new seeds to the surface again.
