Garden lyme

Vinny will know, I'm sure.
I haven't a clue. There's a bag of 20 year old lime in my shed and I still don't know how to use it.

I’m exactly the same. I’ve had a big pile of it sat next to my compost bins just growing a lovely selection of weeds for the last 9 years.   
I know I’ll need it in the new garden. So I’ve taken the weedy rooty top off the pile and dug me a bucket full. 
plus I don’t want to leave it for the landlord     .
