Bought one of these about a year ago and everything up to recently was fine. It's in a wooden planter with drainange holes, about 40cm cubed and has grown up to about 1Mtr high. It's climbing up a trellis on my shed and is facing West.
It's been flowering now for quite a while but I noticed about 2wks ago that the leaves, still green, were beginning to droop somewhat. Oddly enough, for me at any rate, the drooping seemed to start at the top of the plant. Now virtually all the leaves are drooping and I'm not too sure why. The soil is wet but not waterlogged so I'm not too sure what can be causing it. Anyone got any ideas please?
