Texas, like many southwestern states, has colder climates to the north and warmer dry climates to the south. Since pear trees require a winter chill to bear fruit for the season, most varieties cannot grow in southern Texas. The varieties that do grow successfully in Texas are resistant to fire blight, which kills pear trees. Most pear trees in Texas can be found north of the Corpus Christi-Laredo line because the climate in that portion of the state is cool enough during the winter months.
The Warren Pear tree can be found in northern, western and central Texas. The species grows well in many soils and likes full sun. Look for pears on the Warren Pear tree in three to five years after planting. Harvest the pears in late August. This tree will produce medium size yellow-green colored pears with a long neck that are good for eating or canning.
Look for the Ayres pear tree in most of Texas with the exception of the far south. Use cross-pollination to grow this pear. Any variety of pear will work for cross-pollination but the Moonglow variety is the best. The Ayres tree produces medium-sized, brownish-red fruit in mid-August. Use this pear variety for desserts and canning.
Asian pear trees grow in the same areas as the Ayres variety. They do not grow in the far southern portion of Texas. Look for pears that have a similar resemblance to apples on their bottoms, with a rounded shape and a golden yellow color. Pick the fruit in mid-July for use in cooking and baking. This variety has a varied resistance to fire blight as opposed to other Texas pear varieties.
The Moonglow pear tree grows in north and west Texas. This tree is the largest of the Texas pear trees, growing up to 15 feet high and 12 feet wide. Look for large green pears with a reddish blush. Harvest Moonglow bears fruit from mid-August through September. Use this variety of Texas pear tree for baking, canning or eating fresh.
