(fallen london stamps by me: "okay let me see what a castile soap solution does... it's supposed to be an okay substitute for insecticidal soaps but some plants hate it"
me: spritzes a single leaf
the leaf, this morning: burnt along the edges
me: "WAH I'M SORRY"
update, I have been spritzing leaves with a castile soap + distilled water solution and then immediately rinsing off the soap with some tap water spritzes. I have no idea if this is lowering the efficacy of the soap but it does seem like the basil tolerates it much better
also the soap has peppermint oil so it smells really nice
