If the plant was undamaged in the move it looks like you're not watering at all. I'd certainly get it into the shade until it recovers. Remember it only has the old roots. So you are just watering the original rootball for right now. Try to keep that evenly moist not drowned.

Over watering and under watering show the same symptoms, maybe you should give more information in regards. As for the potting soil make sure is suitable for acidic loving plants such as azalea ,camellias and blueberry or else the plant will struggle and eventually dye.

I used Pennington Pro potting mix. For Flowers, houseplants, shrubs, tropical plants, patio containers, hanging baskets.

Has Ammoniacal nitrogen .05%

Nitrate nitrogen .05%

Available phosphate .05%

Soluble potash .12%

So I'm guessing wrong kind of soil mix?

When it was moved everything like the soil and roots remained intact. It was easily removed from the original pot.

Just to add to what others have said about making sure you water enough...I've read that blueberry roots cannot tolerate being dry. So I try to make sure I water my container blueberries a lot in hot weather. I sometimes get those brown half dead leaves towards the end of a hot summer, which tells me I just haven't watered them deeply enough. I've never had a problem from too much watering, and I'm using 5 and 15 gallon containers with a 50-50 mix of peat moss and potting soil.

I just got back from out of town, but unfortunately wasn't able to do anything since last posted. I did put it under shade and set sprinkler everyday for 30 minutes. I don't think it got watered enough. Should have brought it with me. Think there's still a chance with the way it looks now? Should I bring it indoors?

No don't bring it indoors. If it's too cold out then you may need to put it inside an unheated garage. I'd only be concerned below 24F for long periods.

It still has a chance if the stems are still green. The leaf lose this late in the yr isn't likely to have any lasting negative effects.

do you live somewhere with fine hot weather this time of the year , otherwise watering it every day and having a saucer under the pot might be too much ?

You should be able to tell by lifting it up whether or not it needs watering. If it feels light, give it a good watering and lift it again and remember what it feels like when completely wet. But water it by hand so you know exactly how much is going into the container.

Alternatively, find one of the drain holes at the bottom and push your finger into it. If it's soaking wet, you have enough water. Don't water again while it still feels wet at the bottom.

Thank you everyone. Small part of the stem is still green so there's hope.

I live in Florida where the weather will get warmer and lots of rain the next few days.

Hope your blueberry has improved! Don't throw it away if it hasn't - they can made amazing comebacks. Give it until spring. What the others said about acid soil is crucial. You can add a bunch of organic matter to the mix - bagged compost will be fine. Or you can switch out the mix for one made for acid-loving plants like camellias, azaleas and rhododendrons. That's probably the better move because you won't need to wait for the pH to change and the pH will definitely be correct. Dr. Earth Acid-Lovers potting soil is a good choice. If the soil is too alkaline, the mycorrhizae around the roots die and plant can't take in nutrients or water as effectively.

While what you're seeing is probably transplant shock and water stress, being it the right soil will help it heal. A weak sugar and water solution sometimes helps it recover. Meanwhile, don't let it get too much sun. Some is fine.

Once it begins to leaf out in spring, give it an acid-loving plants' slow-release fertilizer. Dr. Earth and Espoma both have good choices.

Good luck!
