Grape Ivy Propagation and the Oxygen Myth

Grape ivy (Cissus rhombifolia) is a popular trailing houseplant that's easy to propagate, but a single cutting in water will only grow longer—it won't branch. For a fuller plant, root several cuttings together in one pot.

How to Propagate Grape Ivy

Keep the cuttings in water until roots are about an inch long, then transfer them to a small pot with damp potting mix. Maintain slightly moist soil at all times. The plant will stay in that small pot for a long time before becoming pot‑bound enough to need repotting.

Do Houseplants Deplete Oxygen?

It's a persistent myth that indoor plants consume more oxygen than they produce. While most plants respire at night (taking in a tiny amount of oxygen), over a 24‑hour period they release far more oxygen through photosynthesis than they use. They also absorb the carbon dioxide we exhale, creating a natural symbiosis. So your 30 plants are actually improving your indoor air quality, not harming it.
