Tea Bags

[Sinbad7]

I've just read online that used tea bags, added to the soil  of an Azalea are good, as it raises the acidity in the soil.  If it's true would it work for my Blueberry's in pots do you think?

I too have heard this, but I would say no milk in the bag if using it one bag per mug.
If milk gets into the soil it can sour the mix. :-X

Yes..but we are talking about used bags and coffee grounds too..not so much acidifier..but more like mulch that will maintain the acidity or only add tiny amount of acidity.

Years ago I had a huge tea pot & I used to make a pot of tea before going to bed & would trot down the garden next morning to water my Camelia. Only in July & August though. I did read it in a magazine, it didn't just pop into my head ;D

A bit off topic, but my grandma used to throw her used tea bags over her hydrangeas to turn them purple/blue and it worked. I've done it as well on mine but never looked into how or why it worked.

The colour of a hydrangea depends on the pH of the soil. She may have had alkaline soil that she wanted to turn acid.

We save our used loose tea leaves, dry them and put round the blueberries. But also add leaf mould and sulphur chips. I was told the tea and coffee grounds don't raise the pH enough on their own. This seems to work well.
