How about brightening your day and your home with eco-friendly house plants?

How House Plants Purify Indoor Air

House plants purify the air through the processes of photosynthesis and respiration.

When we exhale, we release carbon dioxide into the air. During the day, plants take in that carbon dioxide and convert it to oxygen (photosynthesis). At night, plants take in oxygen and release carbon dioxide (respiration) .

During these processes, plants remove air pollutants, such as viruses and chemicals that can come from your carpet, furniture, and paint . This means that a home with plants has cleaner air than a home without, which is important if you have asthma or are sensitive to certain chemicals in the air.

Get Your Home Ready For New Plants

Before buying plants, look at each room in your home. Note how much sun there is at different times of the day. This will help you decide where to place your new plants.

Plan to have about 2 plants per 100 sq. ft./9.3 sq. m.

Some plants, like pothos and snake plants, grow in bright or low light, so they can go in almost any room in your home — even the bathroom which typically has low light.

Others, like the spider plant, prefer bright/indirect light, so place them in areas with more windows — maybe your living room or kitchen.

Caring For Your Plants

Pay attention to water and fertilizer. Every 3-4 days, check your plants' soil for moisture. If it's moist, don't add water. Some plants prefer dry soil, such as aloe vera, so water them every other week. Use water-based fertilizer once a month.

Sustainability And House Plants

The plant industry leaves a significant carbon footprint, but there are steps to protect the planet and still enjoy your houseplants.

Avoid peat

Peat holds moisture in soil. The plant industry uses more peat than can be reproduced and harms wetlands that absorb carbon from trees . Avoid buying plants with peat and use homemade compost instead.

Buy local

Transporting plants long distances generates emissions that harm the planet . Buy locally grown plants and propagate to create new plants.
