Unlike many fruit-bearing trees growing in the United States, blueberries offer the home gardener a chance to cultivate these delectable berries in small backyards as long as the proper conditions exist. Blueberries belong to the heath plant family that includes cranberries, bilberries, huckleberries, azaleas and rhododendrons. Most members of this family live only in North America and all these plants thrive in acidic soils. Creating the ideal soil conditions will maximize the blueberry harvest and help the plants flourish. Coffee grounds can help create these ideal conditions.
