Thanks for the input.
Oirish...just to let you know my current garden layout (right hand side). I have two Himalayan Birch in the bottom right hand corner planted Jan - 1 metre apart. I have planted a sunny bed (butterfly bush, lavenders, rose climbers, summer bulbs etc) 3.5 meters long one metre out (semi circle) also on right hand side.
At the top beside the house is the small patio with sliding doors out, small extension directly left and neighbours patio is directly over the fence (right).
When we come out the patio doors we are overlooked by high climbing frame and trampoline.
I had been planning on planting potato vine at the edge of the border and training it along trellis towards the house (just adding a foot or so height to the fence for two metres from the house to the border edge).
Failing this....
1) Do you think I could put bamboo in large containers along the dividing fence along the patio??
2) Could I add height in the bed with an obelisk and vigorous flowering climber?
3) Should I give up and start again with my concerns for privacy having a higher priority?? (Heartache!).
(By the way the fence on the right is south facing..hence the grand plan for a sun loving flower and shrub bed and we are not overlooked at the bottom of garden).
Any help greatly appreciated........
