Flowers of Sulpur / Sulphur powder

We can't get eracious compost over here so use sulphur powder. I dug in quite a few cup fulls per planting hole, along with some pine needles from my neighbour. The needles are fairly acidic as well. After planting, I top dress more sulphur powder and lightly scratch it in so it doesn't blow away. Repeat yearly in spring. And it does help. Use rain water rather than tap water which often tends to be more alkaline and undoes your efforts.

is it just a myth or can teabags actually help acidify soil? I'm moving  my blueberries from their tubs to a bed in the next few weeks and was wondering whether to dig in a layer of teabags!

News to me! Better to use sphagnum peat moss unless you are a conscientious objector!

Never heard of tea bags/tea leaves as acidic. They contain tannin and are great for bulking up compost though.

Pine needles are far better for acidifying soil for blueberries. Here are more ideas:
