Should I move the blueberry plant or leave it be?

[Frequency]

I'm a very novice gardener, as in I have owned a garden for only a few weeks. I planted a blueberry shrub a week or so ago and it is not looking well. It's all droopy and the leaves are turning red.

Google tells me I should have tested my soil to see if it was acidic and if not, I should've grown my blueberry plant in a tub full of acid soil. I now have acidic compost and a big tub, do I move the blueberry plant to the pot or will that just kill it quicker?

I’d risk it. Make sure you keep it well watered with rain water. Always use rain water.
It most likely will survive, but have fewer fruit. But plants are unpredictable so it could be shocked into having a bumper crop!

The only rain water I have looks green and slimy. It was left in a water butt that has possibly been there years. Will that water be ok?

I'd move it too, and water in with the green water. But I'd also nip off any flowers so that this year it puts its energy into recovering rather than making fruit, specially if it's a small shrub.

You could also organise some water gathering for the dry spells, it sounds as if you’ve a water butt that need connecting to a downpipe. Acid loving plants only really do well on rain water.
