The pH of the soil here is between 5.5 and 6 in most places. I don't add lime to it except occasionally in the vegetable garden. I think if you fertilize plants adequately, even "lime-lovers" are happy in slightly acidic soils. I do grow lilies but would not consider them permanent because rabbits and deer are so likely toi eat the tops, and voles and gophers likely to eat the bulbs. Jane McGary Northwestern Oregon, USA
