Ah, a fellow houndlover. You've come to the right place. there's so much to cover. Type in the search space 'blueberries' as there are lots of interesting and pertinent posts bound to help you out. I assume your soil is not acid enough. granulated sulfur will provide long term help, but you prolly need some ammonium sulfate. I suspect your water is also hard. Are they getting enough water? Moving the plants into full sun will increase production. With the manure you should be rockin' Forget the miracle grow. I quit strawberries. I hate bending over. Mulch the heck out of your blackberries, water 3x a week on everything in this heat. water at base with hose slow soak/3-5 gallons. Sometime when sprinkling, only the top g2" gets wet! I have apache and they love the composted manure. Dont use the fresh manure. Let it compost. Apply in early spring

Aimeekitty, we have the same temps. I am in South coastal Texas. Usually if we have below 32 degrees, it just for 6 minutes. This past winter was diffrent it went down to 26 degrees for over 4 hours. Then 31 degrees for 9 hours. I lost so many plants I had since 1995. I am starting over, and I think I am doing a much better job of selecting plants this time around. They only brugs that survived were the ones that were on the East side next to the house. I'm still not sure which ones survived, I did not have them labeled. Its been fun starting over, I can't wait to see my first blooms. Since our summers are so hot, my best blooming time is in October. I still have blooms in December. Just think, you can post pictures of your blooms to cheer up folks that are snowed in. Barbra

Blueberries are water hogs. My biggest challenge growing them was keeping the potting mix acidic ( local water was alkaline and as the potting soil became less acidic the plants yellowed and wouldn't take up the nutrients I fed them) I grew them from 1 gal to 15 gal plants and then after 3 years in 15 gal pots they deteriorated. I was watering the plants twice a day. An expensive way to get blueberries. But it was fun. Someone said brew up some strong coffee and do a simple ph test. That is what you want your soil to be like. Redwood compost helps to keep the mix acidic longer. Azalea potting mix is good for the small plants.

i see one flower, bottom left arrow the rest look like leaves to me. its real hard to tell until they are large enough to see the difference. Male usually hangs down from a stem. females have a wider bud. Herm's look like females, but , sometimes a bit more narrow Mangodog is on spot about them hating cold-wet feet too. will quickly kill them. I use chicken poo. its high in nitrogen sometimes i use a high N fertilizer with micronutes they respond real good to both. - Mangodog are you sure that is a TR Hovey ? The fruit is hanging down on stems which means it was a male flower. (supposedly) and now a male fruit. I looked at other pics of TR hoveys they are only supposed to get 6-8 ft tall. mine is only 4ft (but still young) you might have something different there. https://logeesblog.wordpress.com/category/carica-papaya-t-r-hovey/ Here is a link that might be useful: TR hovey
