When Does a Pear Tree Mature?

Maturation Time

• The maturity of a pear tree is indicated by its size and fruit production time. A standard variety of pear is mature when it reaches a height of 25 feet with an equal spread, says the book "Better Home & Gardens Vegetables, Fruit and Herb Gardening." A dwarf sized pear tree is mature at 6 to 12 feet. Mature standard-size tree bear fruit within six years of planting. Fruit production in the dwarf varieties starts three to four years after planting.

Planting Time

• The recommended time to plant pear trees is during late winter or early spring for bare-root, dormant trees. Container-grown trees may be planted throughout the growing season. Plant the standard-size varieties 16 to 20 feet apart and the smaller, dwarf varieties about 10 to 12 apart. Pear trees are not self-fertile, and two varieties are required for pollination and healthy fruit set. The trees of different varieties should be within 50 feet.

Tree Selection

• The Texas A&M University Extension website recommends against purchasing any bargain deals on pears. Buy healthy trees from reliable sources with a trunk diameter of about ½ inch and height of 2 to 4 feet. Avoid buying very large trees as the roots of larger trees are more prone to damage upon removal from nursery. Also the 2-years-old or older trees do not have sufficient buds for developing the side branches on lower trunk area. Keep the roots of bare-root trees moist until planting.

Site

• Pear trees require a deep soil to grow well given their deep root system and adapt better in heavy soil than lighter ones. Ensure moist and well-drained with a pH of about 6.5. Trees growing in dry soils are prone to flower and fruit drop. Avoid excessively fertile soils as this increases susceptibility to fire blight. Select a warm area that received full sun for optimal growth. Plant trees at the same depth at which they were growing in containers.
