Young blueberry bushes leaves turning brown

[mtnman]

Hello everyone, newbie here.

I have about 8 two year old blueberry bushes (currently in 3 gallon pots) and one has already turned completed brown while the others are just starting to get brown leaves.

I am not sure if I am over or under watering them which could be the cause. I will get pictures and post them for better recommendations.

Thank you all in advance.

I don't where you are in PA, (I'm 6b/So. Central) but it's happening to mine too. Of course we've had quite a heat wave, this year. High 90s/Numerous days 100+.

Thank you for the response.
I am in eastern PA. Yes it has been hot but I have been watering them daily.
Here are pictures of my blueberry plants (Patriot variety)

The one you can clearly see is dead or almost dead.

My blueberries are now 5 years old, hardly any new growth and only a few good handfuls of berries.. 3 year they had a good run.
pH is 5.2 per MySoil test. Nitrogen is a bit low but I did not feed them after onset if fruit buds?
New to blueberries.

Coincidentally, I just read a new thread from another poster concerning the abundance of trimmings from his blueberry orchard in Michigan. An abundance of trimmings suggests an abundance of pruning. Perhaps he will also see this post and comment.

There should be an annual pruning for blueberries done each Winter. Maybe this Winter, you should try pruning back your bushes to rejuvenate them for increased growth and fruit yield. After five years, it might call for drastic pruning, but I would try to keep younger basal branches from the previous year, as they are most likely to fruit well next year.

I am new to blueberries this year, but it did strike me if you have been watering through a hot summer I keep reading warnings about using tap water on them as they like it acidic. Water from the rainwater butt only.

The amount of rain we had this season was crazy, although when I do water it was with tap water. I will have to change that.
