Thank you everyone for your replies! I will try the fly trap just in case however thank you so much @Rob Thomas! After reading the article and looking at different images I do believe it is quite possible that they are corn maggot flies. Especially since they do not move much if anything when I try to swat them away. I have done the scratch test and it seems that there are a select few branches that are alive. Yet, a large amount (especially the main branches) seem dead and snap easily. Due to this I am unsure as to what their status is. I do know that frost swept over our area since they were planted. Due to this it could be frost damage I'm assuming and if this is the case I am unsure as to what I should do next.

Looks dry to me as well. I have found that when watering with a hose the water will just drain to the sides of the pots and not flow through the mix its self if not kept watered often enough. I have one 15 gallon Jewel doing that as we speak. I need to submerge it and let it rehydrate. Thats one of the problems with peat heavy mixes. Once it dries out it becomes hydrophobic and repels water instead of absorbing it. It needs to be hyrated quickly because its all down hill from here.

The brown areas sort of look like what is happening to a few of mine.I hope it's not.This stuff spreads like a plague.I'm leaning towards bacterial canker that is on my plants. Has it been rainy in your location recently?I think it is distributed that way. I had to cut away a lot from one plant and still don't know if it is going to survive. Here is a link to some photos. Brady Here is a link that might be useful: What the heck is doing this to my Blueberries?

This is the container soil mix recommended by the above touted Dave Wilson Nursery specifically for blueberries: 1/3 1/4" pathway bark 1/3 peat moss 1/3 forest byproduct-based potting soil (azalea mix or acid plant mix) 1 handful soil sulfur per plant. Nowhere in that combination is "actively decomposing organic matter". In fact, that mix is a pretty durable (non-decomposing), long term container mix and the potting mix the OP proposes is very similar. And there is also nothing in that mix that supports the populations of microorganisms required to process non-water soluble organic fertilizers, either. Drew, we've been down this road before, both here and on the Container Gardening forum. You have yet to link to any of these 'studies' that acknowledge the benefits (or even the slightest effectiveness) of using organics in a container situation despite countless other posts and scientific data that state the opposite. Yes, there will be some nutrient release from the organics - its hard to get away from microbiology completely - but not to the degree where the plants are receiving all the nutrients they need to flourish just from that source. btw, much of my background in growing blueberries comes from a professional association with Fall Creek Nursery in Oregon. Fall Creek is the largest wholesale grower of blueberries in the country, supplying much of the stock sold at nurseries elsewhere. Wouldn't be at all surprised to discover that they supply Dave Wilson with their starter plants They are not a fruit tree nursery - they are blueberry specialists - and are responsible for many of the newer introductions on the market, like the Peach Sorbet the OP is growing. I trust their growing recommendations implicitly - it's what they base their business on.
