Hi Janet and Steve, THanks for setting up this website. It is great to have the forum and your expertise at our fingertips (literally). My question is that I had a clematis (Jackmani) for several years planted on a fence. It was fabulous! Several years down the line it's leaves started turning yellow. I put lime on it and it did green up. BUT, after several years of adding lime, I believe the soil had too much of a buildup of acidity. If I remember correctly, the leaves started shriveling up and falling off. SO, I dug out the soil and replaced it. But I stil have the same problem. The clematis does not like it there apparently. Yet it did soooo well there for many year initially. AND, I have another clematis planted just 2 feet away. Does great.
