MO or a few other spots trumpet vine is not a native.
I try to discourage people from planting clinging from buildings. The blooms although pretty do not make up for the maintenance problems and costs.
Explain to your tenants why you are removing the plants and the PROPER use of chemicals should not be any risk to the environment or people. Especially if you are going to replace the plants with natives.
I would suggest cutting the woody parts of the vines off at ground level and treating the x-cut with a mix of round up and tri clo pear (spelling) both vines are very aggressive and will send up sprouts for years. Treat the leaves with a dilute solution of round up every month...
they will die back but then will send up new growth. Treat this new growth on warm days and only get the chemicals on the foliage of what you want to kill.
Any ?s p.m. me.
