Correct soil for Calluna
I have heavy clay soil where I live. Since a raised bed is not an option for my situation, I removed all soil in a large bed area to a depth of 14 inches and replaced it with a mixture of one third topsoil, one third leaf compost and one third pine "fines" ( very small pine bark pieces). I would greatly appreciate input from anyone who has used this method and had success growing Calluna vulgaris. I am told this is the mixture to grow acid loving plants here in Ohio, but I would like to hear from a veteran gardener in my situation.
