Your biggest issue is not which variety to grow, but finding or building good soil. While there are pockets of good acidic loamy soils in MTN, it is more typically thin, neutral, clay/chert on limestone bedrock, or if you are up on the Highland Rim, acidic clay/chert. If you have the thin limey soils, then raised beds may be needed. The acidic red clay on the Rim will need lots of organic soil amendments. A soil test is essential. The one variety that has done best for me so far is Ozark Blue. Mine are just coming into good production, or would have been, if not for the big Easter freeze. I do have scattered berries on most varieties, but lost most of the crop on just about everything. Oneal is a good early variety. It needs more acid soil than most, but flowers over a long period, so spring frosts usually only get some of the earlier blooms. Others doing really well are, Legacy, Sierra, Blueray and Aurora. Blueray is probably the most heat tolerant northern highbush. Aurora is very late ripening and also suffered the least damage from the freeze. Star is a newer variety that a friend with a big blueberry farm near Lebanon really likes. It blooms late, but ripens really early. Aurora, Ozark Blue, and Oneal probably have the best fall colors, although most varieties are really good in that area. If you get a chance, go visit Kelly's Berry Farm just north of Lebanon. After many years of growing many varieties, they now grow mostly Ozark Blue, Oneal, and Blueray, along with some of the old rabbiteye standards, Tifblue and Climax. Unfortunately, they will not have any blueberries this year due to the freeze. They do still have some strawberries, although it is getting late in the season. They also should have a good blackberry crop by summer. Avoid the shade as much as possible. I just moved some bushes that got some partial shade. They just did not grow much or produce well at all, but the same varieties out in full sun were doing great. ~kiwinut

Well it doesn't seem to be spider mites, much whiter and very localized to the blossom end "crater". But yes, it doesn't affect the berry in any other way.

I fight this battle every year, and do pretty well until late winter. Rabbits love to eat young blueberry branches. of course, blueberries usually only produce on 1-3 year old wood, so you may get some fruit, but without some chicken wire or something around the plants, your harvests will always be severely limited.

Here's the yogurt muffin recipe: Oven at 375 1 c. plain yogurt (not Greek) 1 tsp baking soda 1/2 c. butter 2 eggs 1 tsp vanilla 2 c flour 1/2 tsp baking powder 1/2 tsp salt 1 c sugar 3/4 c something to mix in (fruit, choc chips, nuts, whatever) Preheat oven to 375 Grease muffin tin and set aside. In a bowl mix yogurt and baking soda. Set aside. In a large bowl mix flour, baking powder, salt and sugar. In another bowl, beat butter Add eggs one at a tie, then vanilla. Add to flour mix. Then add yogurt mix stirring just until combined. Stir in your mix in. Put in muffin tin and bake about 20 min or until done. Can also add topping such as 2 Tb chopped walnut, 2 Tb brown sugar, 1 tsp cinnamon mixed together. Some of my favorite combos: lemon poppy seed; apple cinnamon and walnut; blueberry; orange peel and cranberry; and of course mini choc chips.
