So, I'm thinking that an alternative to #herbicide would be horticultural strength #vinegar mixed with yucca extract (or perhaps aloe vera) to help it to stick. I will be experimenting with this method over the summer and will post the results!
"Alternative herbicides fall into 7 product categories: Natural acids (vinegar + citric acids), Herbicidal soaps, Iron-based herbicides, Salt-based herbicides, phytotoxic oils (clove, peppermint, pine, citronella), corn gluten, and combination products (including ingredients from multiple categories). This fact sheet concentrates specifically on acetic acid (vinegar) products."

@DoomsdaysCW putting salt on the ground might ruin the soil permanently
@licho TY. Updated my post!
@licho I'm dealing with some stubborn invasives that are "zombie" plants. If you leave a bit of the root, they come back. I've used the boiling water method on a few spots. It's not kind to the soil microbes, but I imagine it's better than salt.
@DoomsdaysCW I have those too. I tried pelargonic acid last year - it completely burned the leaves in just hours but eventually the invasive plants just grew back. Tough problem
@licho Good to know. Yeah, I've tried a lot of stuff (anything but glyphosate). Black plastic sometimes works, and then digging up the roots in question, and putting down some fresh soil and plants. I reclaimed a raspberry patch from fast-growing vines using that method. I have a few spots left, but the raspberries made a good comeback. Once I get the last vine roots dug up, I'll be transplanting some wild strawberries and mint. That ought to take over the spot. Lol.
@licho Lol. So, I tried using used cedar cat litter (no poo) on some invasive winged red bush plants a few years back, and then found out that they thrive on ammonia. Ooops!
