Root Drench

I currently have a big tub of it rotting away at the bottom of the garden. Not much pong at the moment but when the weather warms up it will really get going. I live near the sea and collect my own every time we have a big spring tide. It gets washed up by the trailer load and I just fill a few sacks to add to the compost heap and make my own liquid feed. Take no notice of officious jobsworths who tell you that you shouldn't collect it. If it's washed up and dead it's not a problem and you're not going to be doing it on an industrial scale.

I think the muck & magic aspect merely comes from the fact that it is organic rather than inorganic and therefore will contain trace elements.

After all they do have to the sell their product, and it is not actually completely untrue
