Know now. History of Fruit Production in Eastern Nebraska  1874—Nebraska Horticultural Society proceedings state: “Standing at the eastern end of the great Platte Valley, the time is near at hand when the vista if Nebraska’s horticulture would be like an avenue widening as it extends westward, lined with belts of forest, orchards and vineyards flanked by fields of grain and diversified products. The platforms of it’s railroads covered with thousands of baskets of peaches and small fruits and crowded with barrels of apples.” Know how. Know now. Brownville Fruit District  Nationally recognized fruit production region  Shipped throughout the United States  Apples, apricot, cherries, grapes, peaches, plums, pear, raspberries, blackberries, currants and gooseberries Know how. Know now. 1930’s  1931 Nebraska Unicameral passed a law ordering the removal of cedar trees to slow the damaging affects of Cedar Apple Rust on area apple orchards  Brownville Orchard Company announced their 100 acre peach orchard was bearing crop for the first time. Averaged 500 bushel in sales a day. Know how. Know now. What Happened?  Prohibition– January 16, 1920  Depression– October 29, 1929 through 1939  Armistice Day Freeze—November 11th 1940 Know how.

    • 5 Know how. Know now. Know how. Know now. A. Suckers or watersprouts are vigorous vegetative shoots which drain nutrients needed for fruit production. They often appear at the base of grafted trees, or in crotches and sites of previous pruning cuts. B. Stubs or broken branches result from storms, heavy fruit loads, or improper pruning. Diseases and insects may enter the tree at these sites, so they should be headed back to healthy side branches or removed. C. Downward-growing branches develop few fruit buds and eventually shade or rub more productive scaffold branches. D. Rubbing branches create bark injury which also invite insects or disease. Head back or remove the less productive of the two. E. Shaded interior branches develop less quality fruit and limit access for harvest. Know how. Know now. F. Competing leaders result when suckers or branches near the top of the tree are allowed to grow taller than the uppermost bud of the trunk or central leader. Head these back or an unbalanced, structurally unsound tree will develop. G. Narrow crotches occur when a branch develops more parallel than perpendicular to the trunk or limb from which it originates. As each grows, bark trapped between the two interferes with the growth of a strong joint. H. Whorls occurs when several branches originate at the same point on the trunk or limb. Joints are weaker there, so select the best- located and remove the others. I. Heading back or growth diversion cuts are used to limit or redirect the growth of the central leader or branches. For limiting, cut back to a weak bud or lateral twig; for diversion cut back to a bud, twig, or branch oriented in the preferred direction. Know how. Know now. Espalier Know how. Know now. Insects  Codling moth  Apple maggot  Redbanded leafroller  San Jose scale  Spider mites Know how. Know now. Resistance  Enterprise – early Oct  Freedom – early Sept  Liberty – early Sept All 3 varieties have good vigor and very good resistance to Apple scab, Cedar apple rust and Powdery mildew

Peach  Very susceptible to spring frost  Choose later blooming varieties  Choose resistant varieties  Susceptible to borer damage Know how. Know now. Pollination  Generally self-fruitful with a few exceptions Know how. Know now. Peaches  Dwarf rootstocks have not been adequately developed for peaches  Standard variety for Midwest is Red Haven—Mid July  Bear on 1 year old wood  Disease  Bacterial leaf and fruit spot, Brown rot, Leaf curl  Cankers—Insect and sun scald  Insects—Borers, Oriental fruit moth, Plum cucurlio, Know how. Know now. Pruning Know how. Know now. Pruning  After one year In early spring (before growth begins), cut back the scaffold limbs to an outward-growing bud or branch, removing about one-third to one- half of the previous year's growth. Also shorten lateral branches arising from the scaffolds. Remove any shoots that formed on the trunk below the main scaffold branches. Eliminate shoots that grew toward the center of the tree.  Pruning next five years The framework (trunk and main scaffolds) is now established. Each spring, shorten branches arising from the scaffolds. Shorten branches that tend to grow more rapidly than others. Keep the center of the tree open and remove any dead or diseased wood. Unlike apple trees, peach trees bear fruit on one-year-old wood, so new growth must be encouraged each year.  Mature trees Cut back all branches that exceed 7 to 8 feet in height. This keeps the tree low and manageable. Cut to an outward-growing branch. Remove all vigorous, upright branches arising on the trunk and main scaffolds. Thin out 10 to 20 percent of the one-year-old fruiting wood each year.
    • 7 Know how. Know now. Other Practices  Fertilization  At planting—1/2 cup around trunk 10-10-10  Each year after 1-2 # per year of age up to 5 #  If new growth reaches 18 inches reduce use  Thinning  10% of blooms setting fruit constitutes a full crop load  Additional thinning to 8 inches apart in May Know how. Know now. Cherries  Tart vs. Sweet  Tart Cherry varieties  Montmorency—The standard of Midwest cherry production  Balaton—Slightly sweeter but reputed to be more tender  North Star—Naturally small tree with small fruit. Very hardy Know how. Know now. Cultural Practices  Plant as early in the spring as possible  One cup of 10-10-10 broadcast around trunk  After year 1 fertilize with Nitrogen only—about 1 pound per tree broad cast liberally away from base  Important to keep bare ground around base of the tree Know how.

Strawberries Know how. Know now. Fun Facts  The strawberry, a member of the rose family, is unique in that it is the only fruit with seeds on the outside rather than the inside. Many medicinal uses were claimed for the wild strawberry, its leaves and. root  Queen Anne Boleyn, the second wife of Henry VIII had a strawberry shaped birthmark on her neck, which some claimed proved she was a witch.  In 1780, the first strawberry hybrid "Hudson" was developed in the United States.  To symbolize perfection and righteousness, medieval stone masons carved strawberry designs on altars and around the tops of pillars in churches and cathedrals. Know how. Know now.  Over 53 percent of seven to nine year olds picked strawberries as their favorite fruit.  Seventy per cent of a strawberry's roots are located in the top three inches of soil.  Strawberries are the first fruit to ripen in the spring.  On average, there are 200 seeds in a strawberry  Ninety-four per cent of United States households consume strawberries.  If all the strawberries produced in California in one year were laid berry to berry, they would go around the world 15 times. Know how. Know now. 3 Types  June bearing  Bears for a 2-3 week period in the spring  Long days promote stolons, short days flower bud formation  Everbearing  Produces 3 periods of flowers and fruit—spring, summer and fall but overall less than a single crop of June bearers  Initiate flower bud formation with long days (12 hrs)  Produce few runners  Day neutral  Produce flowers and fruit throughout the growing season  Temp above 70 stifle flower bud formation  Fruit size decreases with warm soil temps  More sensitive to herbicides than June bearers  Produce few runners
