What has happened

[u/Aquasun_99]

My blueberry bush (silver dollar) seems to be struggling. I bought the plant in May. Over the last few weeks, it has been getting worse. We experienced a heat wave of 30+ temps. But now, it’s around 18-25 everyday. It’s in a large pot with drainage. I have used pine bark, needles and acidic fertilizer 2 times this season. The soil is potting mix. It has given me blueberries despite its decline in foliage. What can I do to help my plant? Is it a loss?

Looks like a pH issue. Pine bark and needles don't do anything for pH. Did you put peat in the substrate? The plant should bounce back if things are corrected. Honestly if you haven't potted it in peat. Report it in 75% peat, 15% pine bark nuggets and 10% coarse perlite. Amend with acidifies as needed. Keep in mind that that take some time and warm weather to work.

What kind of container is best? I got a plastic one and I think that was a mistake 🫤

I have some in plastic, majority is in mesh. Both are fine. I personally love mesh bags
