morning glories

If you keep cutting htem just above ground they will die off, do you get frost ? that should kill them off and as long as you don't let them go to seed, that should be the end of them!

Remember that the vines you have now have been dropping seeds over time - you will therefore have new vines sprouting over a period of time. Be careful handling vines you cut down - try not to shake loose seeds. I used inexpensive plastic painters drop cloth to let the vines fall down on - helps catch seeds
