Why are there no pecans this year?

Alternative pecan production (inside and outside the years) is mainly the result of inadequate fertilization. When trees produce a large crop of nuts and there are not enough nutrients for the nuts to ripen and for the tree to store enough plants, food production will be low the following year. When trees produce a large crop of nuts, there are not enough nutrients for that year's nuts to ripen and for the tree to store enough plant food for proper production in the following year. Early defoliation in the fall generally means that no nuts are harvested the following year.

Diseases and insects that affect leaves also contribute to alternate bearing by causing early leaf fall in the fall. Alternative production is believed to be an adaptive response to reducing pest pressure by not allowing a constant supply of nuts, for which pests can thrive. Poor pollination: A single isolated pecan tree can generally suffer from pollination problems. Most pecan varieties shed pollen too soon or too late to properly pollinate the female flowers of the same tree.

If several pecan trees or trees of several different varieties are already growing within a few hundred meters, it is likely that a tree will not be necessary for pollination. Another reason for poor pollination is humid weather during April and May. Rain removes pollen and can restrict pollen movement by wind. Alternative production in pecan production means that a tree produces a relatively abundant harvest of nuts one year and a lighter one the next.

It is characteristic of walnut and other hardwood forest trees. To reduce the effects of alternative production, choose cultivars that tend to be consistent annual carriers and then practice good orchard management. Healthy trees of any variety are better able to produce pecans on a consistent basis from year to year. This year, growers may see less harvest everywhere.

With droughts playing an important role in many western states, as well as strong winds that caused damage to terminals in previous years, and the expected pause in production in the east, the pecan harvest in North America could be scarce among buyers this season. This year is no different, as pecan growers have reported that the first “June” drop of the season wasn't too significant. Many varieties shed pecans to reduce crop burdens, however, grower help is still needed for many cultivars. According to the Missouri Botanical Garden, a pecan tree can take eight to 10 years to produce a crop.

Even after this period, lack of pecans is sometimes normal. The University of Georgia explains that walnut trees are alternate in size, which means that it is common for them to produce a bountiful harvest one year and a negligible harvest the following year. According to the Clemson University Extension, the best way to determine if a pecan tree lacks essential nutrients is to analyze both the soil and leaf tissue of the tree. Diseases that cause severe defoliation can also limit the production of a pecan tree, says Clemson University Extension.

Walnut scab can be detrimental to production; even varieties once thought to be resistant show signs of infection without prophylactic spraying. According to UGA Extension, Georgia is the country's largest supplier of pecans, accounting for approximately one-third of the U. Growers should prepare for a drop in volume next year, which is expected with pecan trees as alternative production plants. Department of Agriculture Zones 5 to 9, walnut trees (Carya illinoensis) are grown for shade, as well as for their nuts.

Although this is not a critical water use stage for pecans, severe drought conditions during this period can affect yield. The solution is to plant two or more different varieties of walnut so that the male flowers of one variety develop in sync with the female flowers of another variety. Wells said grain filling, the stage where walnut kernels become the final product, typically takes place from mid-August to mid-September for mid-September for mid-ripe varieties. Starting in the eastern United States, growers began agitating and harvesting their early pecan varieties, bringing them to market as quickly as possible.

At this time of year, home pecan growers will ask several questions about why their harvest didn't work well. In many cases, when pollination doesn't occur on a pecan tree, it's because male and female flowers simply didn't develop at the same time, explains the Clemson University Extension. Lenny Wells is a professor of horticulture and specialist in extension horticulture for pecans on the Tifton campus of the College of Agricultural and Environmental Sciences at the University of Georgia. Lenny Wells, a pecan specialist at UGA, had said in production meetings that if you could only invest money in one thing for pecan production, then he would seriously consider irrigation.
