Fertilize pear trees at half the basic rate. The basic fertilizer rate may need to be adjusted up or down, depending on growth and fruiting of the tree the previous year. If trees are making less growth than indicated by Table 1, fertilize heavier than the basic rate. If tree growth is excessive, reduce the basic rate to try to bring growth back into desirable limits. The following table indicates the optimum growth rates for various types of fruit trees.
Desirable growth ranges for fruit trees.
Irrigation can result in higher quality fruit and vegetables and the overall health of the plant. Drip irrigation comes in two forms. Emitters are usually used in plantings where there are a few feet between plants, e.g., fruit trees, berry plantings, or perennial plantings around the house. The drip hose is usually used for rows or plantings, like peas or corn, and discarded after one or maybe two years of use. Drip irrigation also makes it easier to maintain a good, consistent water supply to the plants.
