I use the refill packets (metal-like plastic) of some foodstuffs we get here for starting seeds and keeping the extra plants temporarily, so I thought: Why not grow mint in a group of these covers kept close together? In the meantime, my friend also told about his mint plant doing so well, the one that he did not attend to all that much, while the others in the ground, which he took good care of, did not! I told him that I had been noticing this phenomenon with my plant too. He also mentioned that mints did well in self-watering pots. Here I am, combining these ideas. I made bottom holes in the covers and kept the mint cuttings in them with soil and organic kitchen compost. I had a small shallow tray, which is nothing but the base of a bucket that broke (junk otherwise!), and kept these covers in the tray (see picture). Water will be retained in the tray and be sucked up by the soil in the cover through the holes I have made in the bottoms of the covers. The only thing I have to watch for is mosquitoes in the tray water, which I replace every 4-5 days. I'm eager to find out. It should be a success. It will take a bit of time for the plants to become established.
See mint leaves in between. I later kept the Gerbera covers together with a few others in a container, and this is what inspired me.
