Every year is done the same. Thick layer of cardboard, all grass clippings added on top. I use one 40 lb. bag of Miloganite to side dress some of the plants that like extra nitrogen - not all do,e.g carrots, rutabaga,turnips. Even peppers and tomatoes produce much better if they start to run out of excess nitrogen as they go into fruiting, otherwise you are pushing them to keep producing vegetation instead of going to the end game of keeping their species going through seeding.fruiting. Cannabis too for those into that. Most people over fertilize like hell, spreading manure means you are feeding any weeds. Side-dressing your actual plants means the food is where it is needed.you've gotta augment somehow though dontcha? Your soil would be exhausted in a couple years if you arent bringing in manure or compost, or something
I've been doing the organic gardening thing since 1981. I'll stand on my (unabashedly) awesome results. $1500 worth of produce in 2000 sq. feet. * I also don't plant in rows unless absolutely necessary. A carrot seed pack says 4" apart in rows 2 feet apart. FUck that - plant on a grid, all 6" apart in a bed 3-4' wide and never walk between them. 40-80% more production.
