    I have a beautiful hydrangea that was given to me by a neighbor, who grew it from a cutting of her own. Originally it was a deep pinkish-red; now the flowers are shading toward magenta to dark purple. It is growing in a mix of sand and well-composted road cuttings (got those free from when the Public Utility folks trim stuff back from the road so drivers can see better.) Quite a ways down, the soil base is sandstone and very heavy yellow clay.
    Are there any natural (or safe commercial) conditioners I can add to the soil to feed this hydrangea and support its pink-red color?

    Yes, yes! Those were exactly what I needed! Is it already too late to change next year's flower color? Buds have started to form. Nonetheless, I will use bone meal, etc., and be patient. Eden on earth can't be grown in a day. [They also had some very helpful pruning information!]
    Thank you, Silver surfer!

    OK, lime I can get, I think. What about Epsom salts, which I keep for my roses? Would that be acidic, or basic? I mean alkaline! I confuse the two - long time since high scool chemistry!

    Epsom salt dissolved in water is only slightly acidic (pH - 6.0) and not enough to be of any use in the garden. It's used to remedy Magnesium deficiencies in soil and will not change your purple Hydrangeas to pink.
