While we stay warm in our houses this winter, our indoor plants may struggle…
There are some ways to improve humidity for indoor plant health during the winter season by increasing humidity as they wait for spring to arrive.
Home Heating Systems
Many of the things you do to keep yourself warm and comfortable during the winter months can actually put a strain on the plants and soils inside your home. Continuous air heating causes humidity levels to fall and the air can become very dry. This encourages water in plant leaves and pots to evaporate, drying out both plant leaves and soils. If you have humidity controls available for your heating system, set the humidity for 40%-50%. You'll breathe easier, static electricity shocks will reduce, and your plants will perk up as well.
Air Drafts and Vents
Keep your houseplants away from drafty locations, heating vents and fans. These locations contribute further to the drying out of your plants. Keep a closer eye on these plants, as you may need to water more often than you think.
Quick Tips to Improve Indoor Humidity
Water Trays
Fill some plastic or metal trays with a layer of pea gravel and cover the gravel with water. Set plant pots on top of the gravel for a localized humidity boost.
Group Plants Together
Moving your plants together can allow them to protect each other from drafts and share humidity.
Humidifier
A simple drugstore humidifier placed near a group of plants can be very effective. Misting plants with a spray bottle or automated system can be helpful, but be careful to avoid overspray on walls and floors.
Bagging
Some plants, such as rosemary, can be improved by placing clear or translucent bags over the leaves and loosely secured just above the soil level. This climate bubble can really make a difference!
Soil Moisture Meters
If you are not sure when to water your plants, a soil meter can be a huge help.
