I have a row of trees (mostly scraggly evergreens, plus a heptocodium and a few others) approx. 3 ft. apart from each other forming an east border between my back yard and my neighbor's (messy) back yard. The area is quite shady. I want to create a privacy screen (especially within the lower 6-8 feet from the ground), avoiding artificial fences if possible.
If I planted a climbing hydrangea midway between each pair of trees (thus approx. 1 1/2 feet from a tree trunk on either side), would the plants fill in the area as it climbed to create summer privacy (at least at lower altitudes)? I realize they may not optimally flower because of the shade.
Also, would they need additional support? And if so do you have any ideas for support structures that would work for my purposes? I want things to look as natural as possible, since the hydrangeas will likely take quite a while to establish. Plus a continuous fence would not work- I would have to cut down trees.
Thanks in advance,
