This plant is 5 years old and has been turning brown for the last couple of years. I've cut away dead leaves and vines that seem dead. But this year it is much worse. I live in Sechelt, the back garden has N/E light and strong winds in storms. In the drought conditions of the last few summers, we come under strict watering restrictions and by the end of the summer, we're at level 4 (no watering at all). Needless to say, it's hard to keep things going with such lack of water other than what's in rain barrels. So, this plant's problem could be cold, could be drought, maybe disease. I'm planning to cut down all the dead and dying vines and wondering if there's any hope for the plant or should I just replace it? There is a strong new shoot from its base, but the leaves on it have black spots higher up. Second pic shows leaves on new shoot. The background leaves are from old vines.
