I have been gardening this block for 5 years, not an enormous time, but I don't use animal products to fertilise I just use compost/mulching/weed tea/and cover crops.
Everything seems fine. Yet every gardening show or whatever will be like "slather that manure and blood and bone on each year, use fish emulsion, fucking sacrifice your firstborn on that shit". Am I an idiot or do you just not need to do any of that?
edit: not looking for the peanut gallery. Interested in opinions from people who don't use animal products and what their experience has been.
It's all a sham. There's so much blood and bone that needs to be sold so it gets put in fertiliser and a bunch of other crap. No need to put commercialised corpse in your garden, but you may want to reconsider readding your first-born. I had great success with my garden going that route...
100% a way to squeeze more profit out of all the murdering.
