I have been experimenting with putting a 1/2 inch layer of sphagnum moss at the very bottom of some of my indoor potted plants, beneath the soil. I did it for my Peace Lily, since I know they have high watering needs, but also tried it with a Philodendron Pluto, and have had success with that as well. Just a little bit of help with retaining moisture that may want to seep out the bottom. I also bottom water pretty much exclusively. Maybe give it a shot for those plants that you don’t want to water as often as they demand 👀👀
