6. Spider Plants

Spider plants are yet another household plant that does all of the work by propagating themselves for you. These guys are some of the top air-purifying plants you can have in your home, and when they’re happy and healthy, they produce miniature versions of themselves called spiderettes.

The great part is that you don’t even have to cut them off the plant to propagate them. You can put the tiny spiderette into the soil right there next to the parent plant, and it will root before you know it.

This only applies if you want a bigger, bushier plant. But don’t worry; if you want new plants, it’s just as easy. Once the spiderette has put out a node on the bottom, it can be cut off from the parent plant and rooted in soil or water.
