Milorganite and butterflies

Asked December 31, 2019, 5:38 PM EST

Is Miloganite a safe fertilizer to use in my butterfly habitat? What about fish emulsion as well as my own composte?

All of the plant nutrient sources that you have mentioned have different properties that may or may not be beneficial for your butterfly habitat. I would recommend that you test the soil using one of our self-mailer soil test kits, which you can purchase at your local county MSU Extension office or on the website, here:
