Pecan Trees Bloom in April – Hamilton Ranches, Inc.

The beautiful blooms of commercial pecans in the United States did not begin until the 1880s. Pecans were one of the most recently domesticated major crops. Although wild pecans were well-known among the colonial Americans as a delicacy, the commercial growing of pecans in the United States did not begin until the 1880s. Today, the U.S. produces between 80% and 95% of the world’s pecans, with an annual crop of 150–200 thousand tons from more than 10 million trees. The nut harvest for growers is typically around mid-October. Historically, the leading pecan-producing state in the U.S. has been Georgia, followed by Texas, New Mexico and Oklahoma; they are also grown in Arizona, South Carolina and Hawaii. Outside the United States, pecans are grown in Australia, Brazil, China, Israel, Mexico, Peru and South Africa. They can be grown approximately from USDA hardiness zones 5 to 9, provided summers are also hot and humid.

Pecan trees may live and bear edible seeds for more than 300 years. They are mostly self-incompatible, because most cultivars, being clones derived from wild trees, show incomplete dichogamy. Generally, two or more trees of different cultivars must be present to pollinate each other.
