I've seen most of the trellises go all the way to 20'. I'm wondering if I can do something a bit different. Have a couple 10' poles connected w/ twine of say 10 feet or so, and give myself plenty of room? I.e. do the hops NEED to grow up? Or can they grow laterally along a string once up to about 10'?
I probably COULD go all 20' up but my neighbors may not be so happy to see the huge trellis in my back yard. I have a big yard, but would rather not tick off my neighbors
