Trachelospermum jasminoides problem
I have 3 TJs, planted this spring in a brand new garden (new house) all growing up columns on a pergola. One is a healthy green, one is showing signs of leaves going red but otherwise looks relatively healthy and 1 is looking decidedly sick with wilting red leaves! All have flowered well up til now. Any ideas as to what I need to do to save the poorly one and is the other one with leaves turning red likely to go the same way? I have been watering them up til recently when I read that they don't like too much water, so I've stopped that. The soil is heavy clay to which we've added compost and a few inches of bark.
