My Brazilian spinach has been doing especially gangbusters, even the one at the back balcony which had always kinda done poorly. I give all credit to...
Prawn poo.
Yea, really! Prob the best fertilizer you can get!
So when you deshell and devein the prawns don't throw them away. Wash the shelled prawns and shells (including the heads) in water. Pour the water onto your vege bed.
For the shells, in Malaysia, we often boil them and use it as stock.
Then, you can bury the shells. Great compost.
