Misting is the classic advice, but it makes little difference. The water on the leaves evaporates within minutes, so the air around the plant is soon as dry as before. The Nebraska Extension points out you would need to mist every few minutes to matter, and wet leaves can encourage leaf diseases, and Virginia Cooperative Extension lists African violets among plants that dislike wet leaves.
Things that help more:
Grouping plants. Leaves release water vapour, so a cluster of plants makes a small pocket of slightly moister air.
A pebble tray. Fill a shallow tray with pebbles or clay balls, add water to just below the top of the stones and stand the pot on them. The pot must never sit in the water. The extra moisture stays close to the plant.
A humidifier. For genuinely humidity-hungry plants in a dry room, a room humidifier makes the biggest steady difference.
Choosing the right spot. Bathrooms and kitchens are often more humid; spots beside heaters, vents and air conditioners are drier. And if your home is dry, choosing tolerant plants is a perfectly good answer too.
Key points
- Misting raises humidity only for minutes.
- Grouping plants, pebble trays and humidifiers help more.
- Keep the pot above the water in a pebble tray.
Try this
Group two or three of your humidity-loving plants together, away from vents, and watch their new leaves over the next month.
