![]() Will flow downhill until something impedes its course. High site with good air flow can decrease the probability of frost damage. Spring freezes can eliminate crops in frost-prone areas. Other helpful site characteristics for pear production are elevation and air drainage. Production and longevity is greater in soils that drain well and are not waterlogged. Peaches and many other stone fruits, can tolerate soils with high clay content however, ![]() Pears grow best in deep, well-drained soils with an optimum pH of 6.5. Selecting resistant cultivars is the most effective The affected tissue turns black and dies and acts as a source of inoculum thatĬan spread to other parts of the tree. Is a devastating disease that appears in the spring affecting blooms, leaves, and To deal with – earlier bloom and greater susceptibility to fire blight. Pears are grown very similarly to apples, but have two additional limiting factors Only about a dozen cultivars have been grown commercially in “apple-pear.” Asian pears include hundreds of cultivars with widely ranging colors,įlavors, and shapes. The round shape and sweet crisp flavor has given the Asian pear the nickname of ![]() In processing than for fresh use, but some newer, improved cultivars have a smootherĪsian pears include many Pyrus species, including P. Have more stone cells and the texture can feel “gritty.” They are used more frequently Tolerant of fire blight than the European and Asian cultivars. Oriental hybrids are usually considered more adaptable and more ‘Orient’ and ‘Kieffer’ are the two main cultivars,īut many more exist. European cultivars include ‘Bartlett,’ ‘Bosc,’ ‘D’Anjou,’ These are smooth and sweet with colors rangingįrom green to yellow to red.

Today Oklahomans have many more choices of pears Produced fruit that today would likely not be up to the quality standards of a commercial Productive and long-lived, the old cultivars The hardy, adaptable pear tree soon followed. Once Oklahomans established their roots in the state, Let me know if I can be of further assistance.On many “old home” sites in Oklahoma, where the first land runs were held, one canįind old pear trees growing. Photos should include one of the entire tree and one or more of the affected leaves. How recently was the tree planted? What is it close to - road, driveway, pond, etc? Is it in a particularly wet or dry location? Has it recently been pruned or damaged in any way? Have you observed any insect activity on the tree? Are you aware of any chemical spraying on or near your property?

If you decide it is fire blight but want confirmation, an on site diagnosis would be best. ![]() Here are two good articles about fire blight and how to manage it: The timing and the wet spring weather make this a likely suspect. That said, there is a common disease called 'fire blight' that affects callery pears including Bradford. So in order to accurately diagnose your issue, I would need additional information as well as photos of the tree including close-ups of the affected leaves.
