I have two large bushes which I'd like to join into an archway over my driveway. Apart from mowing the lawn this probably my first green fingered endeavor, so please go easy!
I've attached two images of the bushes in question.
So -- is is possible? What should I do to have them join? Will I need to build a scaffolding up there for them to run across, or should I tix them together? Or do I need to wait a couple more years for them to grow more before doing anything?
Any tips will be much appreciated.
