My plants are outside and really starting to smell. They are pretty tall as well. Is there anyway i could mask or get rid of the smell? As well as stop their verticle growth. My neighbours are pretty close and our whole property smells!!!

I don't want to cut them down but it looks like i might have to.

The biggest is 6-7 feet tall.
Please help!!
Also i would like to induce flowering because i don't want them to get killed by the frost!
