Adventures in Blueberry Farming in Hamilton County Ohio Lazy FRUIT RANCH 1 Discussion Guide • Why? • Lazy S Background • Blueberry Cultural Needs – Soil Chemistry – Fertilization – Pruning – Other Stuff: Irrigation, Pollination, etc. • Recommendations 2 Why? • I Like to Eat Them – Best Cocktail of phytonutrients (anti-oxidants) – Lower cholesterol, reduce urinary tract infections, better night vision, improved memory & motor function, etc. (Source: Human Research Center on Aging, Tufts University et. al.)…better 1 cup (150gm) = 84 cal than an apple a day! % of USDA Daily Reco Vitamin K 35 Magnesium 25 Vitamin C 19 Fiber 14 Anti-oxidants 1000 3 Why?

Northern Highbush = Vaccinium corymosum • Water – Good Drainage, but Evenly Moist – 1-2 inches/wk • Sun = Full • Pollination – Self-Pollination… • but 2-3 varieties ↑Yield – Who = Bubble bee • Nutrient Needs: More on this later • Soil Chemistry = Low pH – – – – – In Ericaceae Family (Heather, Heath, Cranberry, Azalea, Rhodo) Blueberries like pH of 4-5 (Normal 6.5 – 7.5, Fruits 5.5 – 6.5) Vinegar pH = 4-4.5, Soap = 8.5-10, Peat Moss = 3-4.5 Hamilton County Average pH = 7.0-7.8 Hard to hold pH low if Ca is high (> 1000ppm (2000 lbs/acre)) 5 So What Do They Want?
