Step one. Dig deep trenches.
Step two. Get some fish heads from your local fish shop, keep them frozen. It makes life easier. Place them in the trenches.
Step 3. Add bone meal, worm juice, compost and some crushed Disprins ontop of your fish heads. I know they look like dead rats, but I assure you they not 😂
Last step. Close it all up and you ready to plant.
