Fruit trees tired and neglected beyond a point can never be brought back into full bearing, but that point can be surprisingly far along in their lives. And even if you fail to revive its yield after a couple of years of trying, an old fruit tree will reward you with blossoms and shade until you decide to replace it. Two factors have basic bearing on fruit production. One is chemical. All tree fruits grow best in soil just slightly acid, from pH 5.5 to 6.5. (Some bush fruits, such as blueberries, require pH 4.8 to 5.0.) Testing your soil's acidity and adjusting it with lime or aluminum sulfate is thus a must for fruit culture. |
