Here are some African violet pods I invented. No soil, and much easier to maintain. They can grow like this in full sun, and flower easily. I add a drop of AV food every now and then.
The bottles are apple juice bottles. Put a leaf in the bottle, wait a month. Instant plant! The problem is that once they start growing new leaves they can get stuck in the bottle. Instead, we want to mount them on a surface.
Solution, a felt box pod: cut two slots and feed some acrylic felt through. Fill with water, cut a slit in the middle of the felt and thread the roots in.
