how best to reuse compost



I have an all concrete garden so everything i've grown has been in pots and a reusable large grow-bag (almost 100 litres).

Having harvested my garlic and onions i have alot of used compost that ideally id rather not waste if possible.

I know i shouldn't plant onions or garlic in the same soil again.

Can i do anything to it so that it can be reused and if so what would be best to plant in it?

    Mix it half and half with new bag compost, add some slow release granular feed or FBM, and use it for growing another type of plant.
