There are many organic choices for garden fertilizer. You can choose a ready to go retail product available at most garden centers. (even wally world has organic choices now)
But a better choice (in my opinion) is using organic compost as your fertilizer. And being a worm farmer, I recommend vermicompost (worm poop).
When planting your garden, you can use compost in your planting mix. I do and mix it with coconut fiber, some may choose to mix it with peat moss.
After planting , you can make
and then apply it as a foliar spray or root drench.
If you choose to use vermicompost, it works as your fertilizer, but it also works as an organic fungicide and organic pesticide. Yes, it does everything. And the the red wriggler worms do all the work.
Making the decision not to use harsh chemicals on your lawn and garden can make a positive impact on your health and the health of your soil. I made this decision soon after my firstborn was diagnosed with asthma, to help reduce her exposure to harmful chemicals.
