I decided to freshen up my vegie patch and since I live close to a race course, there is always free horse manure waiting to be collected. The stables leave it in bags outside on the footpath.
So I collected 6 bags. OMG, that stuff stinks, and of course it was fresh, straight from the horse's bum

so I got a cloud of flies descending on the garden to visit it.
I couldn't open my door to the garden for a few days because of the smell. Then it rained, Yeee, a rare event her but it seemed to help the smell die down.
Then I noticed the maggots

Is there a board on how to concrete over ex-vegie patches
