Only potential issue with this is it's quite acidic. If it's just your own used grounds I doubt the quantity would matter but if you're getting it by the butt load from a commercial operation you might end up changing the ph of your soil considerably. So, perfect for azaleas, camelias etc if you have them, but terrible for brassicas etc

Might be part of why I’m not very good at growing brassicas!

I read somewhere that is actually only very slightly acidic because the water has effectively washed it out already.
The canteen at work used to have bags of it, but they've gone now. I should probably ask them.

I have lots of coffee grounds in our compost bin, the worms love it.
I don't use these straight on the soil, I imagine mixed with other greens in the bin the grounds are good once decomposed?
Soil pH is 6 and iron rich.

If you can get used ground coffee from local coffee shop can make a very good mulch. Usually they have loads and happy to give it for free. No weeds germinate in it and it will feed the soil over winter.
