Encourage blooms on azaleas and gardenias

A little bit of acid goes a long way toward bringing out the blooms on your azalea and gardenia bushes — especially if you have hard water. Both bushes do best in acidic soils (with pH levels between 4 and 5.5). To keep them healthy and to produce more flowers, water them every week or so with 3 tablespoons white vinegar mixed in 1 gallon (3.7 liters) water. Don’t apply the solution while the bush is in bloom, however; it may shorten the life of the flowers or harm the plant.
