Adam, Your tree peonies want the soil to be slightly alkaline. We apply lime twice each year (and ash from the fire continuously). The chlorosis would suggest that you need to add iron (iron chelates). Your azaleas, like camellias and rhododendrons however want a lower ph (by preferably 1-2 units).
