My blueberry plant is unwell and I can't figure out what's wrong
This is Blumhilda my firstborn. I brought her home back in April. It is my very first attempt at raising a plant (the other ones belong to my grandparents).
I managed to figure out the first couple of health issues (too-damp soil and soil that wasn't acidic enough) and managed to resolve them on my own.
Then the leaves started crinkling and turning all grey and spotty; reminds me of TV static in appearance. The grey stuff I'm pretty sure came after the first leaves started wilting, but I'm not positive. I thought I had accidentally let it dry out; I decided to hold off after the last watering since the soil was damp and then just sorta forgot for a week or two. But even after watering and covering the mulch in saran wrap, the problem persisted and now the leaves look worse than ever because the ones that aren't already wilted are going grey one by one.
I suspect poor drainage might have something to do with it; I did think it was odd how the pot at the store didnt have holes like my mom's did growing up but didn't opt to find anything else because I figured I didn't have anything to drain the pot into anyway. But googling it doesn't help me explain the leaves so now I am here.
If anyone knows anything, please help me help this poor baby!
