Answer: You are wise to plan ahead for your blueberry planting. First, and perhaps most important, is that blueberries like an acid soil with a pH of 4.2 to 5.2. A soil test is the best way to determine your soil's pH. (Burpee's sells a test kit, or you can contact your local County Extension agent.) To make a soil more acidic, add partially decayed oak leaves or acid peat. If your soil is sandy, just add this organic matter; if it is very heavy clay, you might want to mix in some sand in the planting hole to lighten it up. (Just be sure to dig an extra large hole, and mix these additions into the soil you place around the roots.) You can also add some compost at planting time.
