At some point, I killed the front lawn, lay landscaping fabric down, covered it with mulch, and planted cacti at small holes in the landscaping fabric. And, at some later point, the lawn decided that it would send out runners over the landscaping fabric so the entire thing looks sloppy and gross. I’d love to kill that grass but most herbicides are really pretty nasty, particularly those by Ortho, part of Monsanto. Of 30 known herbicides, 19 are carcinogens or linked to cancer. And kill fish, birds, and bees.

These products were recommended by Ideal Byte for gardening and particularly weed-issues:
Deadeye - made from vinegar, it’s non-toxic to humans but will put weeds (and grass, so watch out) in their place ($10).

WOW! (With Out Weeds) - made from a corn syrup byproduct, corn gluten, it’ll kill weeds and release nitrogen for your lawn at the same time ($9).

Weed-Aside - applied directly to weeds it really hits the spot - and leaves the rest of your plants alone ($13).

Ideal Bite’s Fabric Groundcover Tip - reduce weeds by laying down old pieces of fabric and placing mulch on top.
