Sprinkle it on your garden, or else in a layer in your compost bin.

i use it as a soil condition too. I sprinkle it around the shrubs.

I put them around my plants too.

I would always use it mixed with other materials as if you have fed tomatoes or cucumbers in it with high potash feeds, it may be too strong for other plants - the compost bin sounds like a good option to me :)

Yep, I mulch my plants with it too.

put it around my shrubs for years without a problem but I also feed with a balanced fertilizer in the spring
