What's killing my Chilean glory vine?
Hi, I'm hoping somebody on here is an expert on Chilean glory vine. I have one planted behind the woodshed in a sheltered spot. It is usually fabulous and indeed has been fabulous this year - but over the last few weeks it has pretty much curled up and died, just gone mostly brown and dry. Can't see any signs of virus or fungus or anything. It is planted in a gap pretty much surrounded by concrete (public path other side of fence, woodshed base and our garden path, then house wall on this side) and so, though it has been okay every year til now, I wonder if maybe the dry hot weather has simply dried out the earth all around it and our watering through the hole it is planted in hasn't been up to scratch. Not a lot of rain gets in through there. Also, there's a couple of sacks of salt we keep for winter nearby, maybe they got too close and leaked - what does salt poisoning look like and how much salt does it take to kill something? Are there any known diseases or anything it could have? I'm gutted - I had trained it all over the fence and trellis and it was looking the best it has ever looked, the biggest ever as well. Cut it back to within a few feet of the ground every year, it is about five years old now. Thanks!!
