Tea grounds in soil

[k3kr]

Should I add tea grounds to my soil?
I have plenty of it and they've been stored outside open to the elements for over a year now
I've used them for germinating seeds and they retain quite a bit of water
Since I don't have access to coconut coir I was thinking of using tea grounds as a substitute
Pic unrelated those are my succulents

Go for it. I use everything I can get for free. Coffee grounds go on the lawn daily when I wash out the pot, and it seems to be improving.
