Hi, I planted a Clematis in the ground, facing south, it was at an angle so the plant could climb up to a fence and on to an arch trellis. The plant was well watered in and started to grow. When it was about 5 or 6 foot the stems halfway up the plant (not actually touching the fence) became black, the previously healthy leaves then just died. Like an idiot I went out and bought a more vigorous variety Clematis, but the same thing happened.
Any suggestions would be most gratefully received. Thank you.
