Overview

Introduced in Britain in 1994, the Concorde pear tree is known for its early and prolific fruit production. The tree is a cross between the Doyenne Du Comice and the Conference varieties. Its fruit is elongated, with a yellow skin with pink undertones and a sweet, slightly crisp taste when mature. The Concorde pear tree is self-pollinating--that is, it does not need another pear tree to pollinate.

Maximum Height

Concorde pear trees grow, as most pear trees do, to reach a height of 25 to 30 feet. Standard Concorde pear trees are grafted onto pear seedling root stocks. These root stocks are hardy and capable of withstanding cold winters. They have an upright growth habit, so they don't require as much space as spreading fruit trees, such as apples. Space them 15 to 20 feet apart, according to the University of New Hampshire Cooperative Extension.

Exceptions

Dwarf trees are grafted onto quince root stocks to produce trees half the size of standard Concorde pear trees. While convenient to maintain and harvest, dwarf trees are less winter hardy and are more susceptible to rot and fire blight. New semi-dwarf trees are hardier than dwarfs and grow to about 15 to 18 feet high.

Growing Conditions

To keep Concorde pear trees healthy and to ensure they reach their potential height, gardeners should plant them in full sun in a well-drained location. Amend soil with organic matter and water them to keep the soil evenly moist during the first summer. Trees that grow quickly are more prone to fire blight than those that grow moderately, advises the University of New Hampshire Cooperative Extension. Gardeners should avoid excessive fertilizing for this reason. Young trees may need 1 lb. of 10-10-10 fertilizer applied in the spring, while older trees probably don't need any fertilizer.

Pruning

The Concorde pear tree's upright growth pattern makes it prone to breakage, especially when the tree is heavy with fruit. Gardeners should prune the tree to create a more open canopy, removing branches with narrow crotches. Gardeners may also train lateral branches to grow at a 60- to 75-degree angle from the main trunk by gently bending them and securing them with twine to a stake. The ideal height of a standard Concorde pear tree is between 15 and 18 feet high, according to the University of New Hampshire Cooperative Extension. Prune the main leader back every two or three years to maintain this height.

Thinning

Concorde pear trees produce fruit earlier and more prolifically than other pear tree varieties. This characteristic may seem like a good thing, but young, fragile branches are prone to damage when laden with fruit. Gardeners should thin at least half the fruit from young trees to ensure a healthy, strong tree. Once the tree matures, the branches are strong enough to withstand heavy crops of fruit.
