How can I convert my clay slope into a REAL rock garden??
I inherited a wonderful spot for a rock garden when I bought my house a few years back. I immediately added tufa, alpines, some gravel, etc.., and have more or less treated it as a rock garden. Problem is that it is a slope with about 10 feet of clay as the bed. I can't afford, nor have the strength of back, to dig it all out and re-do it 'correctly' like scree or sand, etc.. I have ideas about digging holes with a large drill bit, and just keep filling them with sand and such to over the years loosen the soil (I can't dig big holes because gorgeous tulips, frittilarias, etc.. all dug in). The garden does 'okay', but isn't optimal I know. Any ideas on how to improve without starting from total scratch? The link here shows some shots of the area to give you an idea..click on the thumbnails for best view. (Alot of the alpines are covered over by the ferns and such that are thriving in this area!)
