What can I use instead of glyphosate to kill unwanted grasses and other non-broadleaf weeds?

I think the above question is very specific and detailed.  However, I do have one additional question, the answer to which I can't find on your website:  What fertilizer do you recommend for perennials and when and how often should it be applied?

Dear Rod,
It looks like another MG answered your question about alternate ways to remove grass (& other monocots).  Here is a different fact sheet.  https://www.xerces.org/sites/default/files/2018-05/18-002_01_XercesSoc_Organic-Site-Prep-Methods-Overview_web3pg.pdf

Please LMK if there are other unanswered questions.
Thanks,

Thank you, Pam.  I have never even heard of solarization, but that is especially interesting for some of my rocky landscape!  I am excited to try it on some of the larger areas where it seems that all our local, native weeds meet to socialize and grow!
