We have a good sized jasmine (I think it's a confederate jasmine but not sure). It's on a trellis up against a south facing fence. I started to do some pruning, planning to just cut off the dead leaves. The more I looked at the plant it seemed like everything was dead. There aren't any new shoots or buds. The leaves are brown. They don't just fall off, you have to pick them off. The plant doesn't appear to be dead but nothing is growing or getting bigger or anything. The Pacific Northwest is rainy but the soil drains well.
My questions is should I keep the plant or pull it up and start anew?
