Copper chloride hydroxide is most likely either a mixture of hydroxide and chloride, or so called basic salt. Both chloride and hydroxide will react with soil components, giving finally some mixture of copper compounds. I suppose to some extent regardless of which copper compound you start with, you end with some mixture, with exact composition determined by the soil. In the non acidic, carbon dioxide rich environement (soil and humus), copper will easily precipitate as carbonate or basic carbonate.
