If properly taken care of, a pear tree can live for up to 100 years. Pear trees can bear fruit in such abundance that the limbs can break under the weight if the pears are not harvested. The fruits can be made into pies, jams and jellies. In the grocery store, pears frequently are passed over in favor of showier fruits such as apples. Although there is some debate among growers as to whether fertilizers and soil amendments can improve the sweetness of tree fruits such as pears, most growers link the sweetness of fruit to the amount of sunlight a tree receives.
Mix six handfuls of sulphate of potash and 2 tbsp. of Epsom Salt in a 5-gallon bucket of water.
Pour this solution around the drip line of the pear tree.
Mix a solution of 1 cup of sugar to 1 gallon of water.
Add this solution around the drip line of the pear tree.
Prune trees that surround the pear tree so that it will receive a maximum amount of sunlight daily. Most gardening experts say that the only thing that truly sweetens fruit is the process of photosynthesis, which creates natural sugars in the plant.
