We just moved in to a 21 year old home and have a trumpet vine climbing the front porch - it looks very old, is not very big around. We have very high salt content in our well water, we live on land that was used in the coal mining era, the soil is grey and we are going to replace or replenish it where we want to garden. The trumpet vine must have been watered with that well water for years. Anyway, the leaves are all mostly yellow or green with yellow veins, very few really healthy green leaves, about 10 feet high and not one flower on it. Any ideas how to make it flower and get it back to being green? I have fertilized it and we are getting clean water to the gardens now, as well as putting in two large cisterns which we will fill with city water trucked in, but it is still very yellow. I don't think it could have chlorosis, because there isn't any chlorine that we know of in the water. Thanks!
