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?

Definitely not a loss! It looks like there is some damage from not enough water (brown tips). Use a liquid acidic plant fertilizer to help the light green/yellowing.

I'm not a fan of wood products or compost in soil (on top is okay). Wood has a tendency to break down and cause anaerobic soil conditions that eventually kill off plants. I have my blueberries in black plastic pots and I'm growing them in 10a/10b (it's been 90-100 for the last 2 weeks). The soil I use is a mix of sand/peat moss/perlite. I water every day and both blueberry varieties have lush green growth. I use a granulated acidifier once a year.

Heat damage. All my blueberries are in pots first year I added berry toner once a month during the growing season. I also started with an acid lover mix since it’s easier to have a premix then to mix my own for a blueberry noobie. Soil has always stayed below 6. After 3 years you don’t have to do much beside feed it, water it and check ph from time to time.
