I really like houseplants: They’ll actually open up a room and are such an effective way to fill an area. I at the moment have a reasonably Cash Tree plant that’s pet-friendly and provides the proper pop of inexperienced to my desk area.
I’m not alone: The houseplant trade is booming. In 2019 a survey revealed U.S. houseplant gross sales elevated by 50% to $1.7 billion in three years’ time and that development has snowballed since then.
However is that this horticultural passion eco-friendly? That is determined by the way you get your plant infants, and the way/the place they had been grown.
Mockingly, inexperienced indoor areas can come at a value to the surroundings.
Like the whole lot else we purchase, houseplants even have an environmental affect. There are a number of elements to think about, corresponding to “plant miles”, plastic waste and peat moss harvesting.
Right here’s what it is advisable know in regards to the plant trade’s environmental footprint, in case your plant obsession is contributing to it, and what you are able to do about it.
environmental impacts of houseplants
Vegetation could also be inexperienced, however that doesn’t mechanically make them eco-friendly.
There are a number of environmental impacts of houseplants to think about. Listed here are just a few that we are going to be diving into:
- Plant miles: How far did your plant journey to get to you?
- Plastic waste: Plastic pots are the first container used to accommodate vegetation.
- Peat moss harvesting: Peat moss, an ingredient in most potting mixes, is being overharvested.
plant miles
Lots of the houseplants we love come from tropical or subtropical environments. That’s a giant purpose they thrive indoors as a result of they want persistently heat temperatures.
Most houseplants are imported from abroad and journey a whole lot of miles earlier than entering into our properties. The Swiss Cheese plant is only one instance: It hails from Panama and southern Mexico.
Transporting vegetation over lengthy distances, whether or not by aircraft, boat or truck generates a variety of carbon emissions. That is also known as “plant miles,” aka the full distance houseplants journey to get to you.
Nevertheless, plant miles aren’t the one downside: It’s how they’re harvested that additionally issues. Plant poaching is an actual menace because of rising curiosity in uncommon vegetation and the way a lot they fetch on the black market.
For instance, the World Heritage Website is the world’s most biodiverse desert. Greater than 3,000 plant species exist in a comparatively small space. A lot of them are prized succulents that fetch excessive costs on the black market.
A few of these species stay in an space smaller than a soccer area, so it might be very simple for a poacher to render the species extinct in a single morning.
Because of this, it’s so necessary the plant trade turns into extra clear about the place they’re sourcing their vegetation.
what about houseplants grown in greenhouses?
One potential answer to fight plant poaching is to develop houseplants in a greenhouse. Nevertheless, that is an imperfect answer, as greenhouses are big power suckers doubtless powered by fossil fuels.
Greenhouses are outfitted with lighting and high-tech irrigation programs that require a variety of power to take care of, particularly for fickle houseplants that want a certain amount of heat, daylight, and water.
Whereas greenhouses actually lower down on plant miles, and guarantee there’s no plant poaching, they’d be much more sustainable in the event that they ran on renewable power. Sadly, many don’t, or usually are not clear about the place they’re sourcing their power from.
plastic waste
Plastic pots are the primary container used to accommodate most indoor vegetation. Nevertheless, most houseplant pots are constructed from polypropylene (plastic #5) which isn’t broadly accepted by way of curbside recycling companies. Altogether, just one% of plastic #5 will get recycled within the US.
Which means if you wish to switch your houseplant right into a extra fashionable container, the plastic pot it got here in will doubtless find yourself within the trash. In truth, in keeping with Marie Chieppo, Principal at EcoPlants Plans, 95 to 98% of all plastic plant pots find yourself in landfills.
This can be a large downside for the surroundings, contemplating plastic’s life cycle is carbon intensive from starting to finish.
Plastic is a non-renewable useful resource that’s constructed from crude oil, which is extracted from the earth by way of fracking. It’s then manufactured into plastic in a fossil-fuel powered manufacturing unit that makes use of a variety of power and water.
Total, solely 5-6% of plastic will get recycled. The opposite proportion leads to our landfills, surroundings, or incinerated.
Plastic by no means actually breaks down. Whereas it’s technically biodegradable (which merely means it would break up over time), it can’t be absolutely returned to the soil (aka composted).
Which means over the course of a whole lot of years plastic will break down into microplastics. Microplastics have already been present in human blood, feces, and placentas. It’s estimated we eat 11,000 microplastics per 12 months, and the well being results of this are nonetheless unknown.
Regardless of all this, avoiding plastic pots is sort of not possible if you would like a houseplant. They’re used virtually solely.
peat moss harvesting
One other large environmental affect of houseplants is the soil used of their pots. Usually instances, houseplants can be planted in soil that accommodates peat moss.
Peat moss prevents vegetation’ vitamins from washing away throughout waterings. It could additionally maintain a number of instances its weight in moisture, then launch that moisture into the plant’s roots when wanted.
However the issue lies in its harvesting, which requires the fixed disruption and overharvesting of peatlands.
Peatlands are wetlands that play a vital position for stopping and mitigating the results of local weather change, lowering flood danger, preserving biodiversity, and guaranteeing protected ingesting water.
These wetlands are the most important pure terrestrial carbon sinks, that means they retailer extra carbon than all different vegetation sorts on this planet mixed.
When peatlands are broken and harvested for peatmoss, this results in a serious supply of greenhouse fuel emissions. In response to the IUCN, ~5% of worldwide greenhouse fuel emissions from land use come from broken peatlands.
To extract the peatmoss, tractors scrape alongside the floor of peat bogs, which releases CO2 again into the ambiance.
Peatlands may catch fireplace, which they typically do when harvested in dry circumstances. Burning peat is much more polluting than burning coal and may have extreme results on human wellbeing.
This additionally impacts wildlife too: The IUCN attributes the 60% decline of the Bornean orangutan inhabitants to the lack of peat swamp habitat over a 60-year interval.
how do you develop houseplants sustainably?
Okay, so now that you simply’re conscious of the issues, lets discuss in regards to the options!

use sustainable potting soil
Peat-based soil is mostly utilized in houseplants. However peatmoss bogs are very important carbon sinks which can be being overharvested, which is contributing to local weather change.
As an alternative, search for peat-free soil, like Rosy Soil, which as an alternative makes use of biochar, compost, pine bark fines, mycorrhizae, pumice, and sand. There aren’t any artificial components of their soil mixtures. Their packaging is recyclable and constructed from plant-based components.
It’s additionally a fantastic thought to start out shopping for your houseplants from a clear and sustainable firm like The Sill. All their vegetation are potted in natural potting soil that’s constructed from a mixture of worm castings, coir, compost, aged pine bark, and rice hulls. It’s fully peat-free.
Plus, The Sill supplies upcycled develop pots as an choice, they usually use carbon impartial delivery on practically all their on-line orders.
You may also simply use compost you made your self! Right here’s the way to compost in your backyard.

For smaller areas, Lomi is a superb choice as a result of it creates nutrient-rich Lomi Earth (aka pre-compost) which is wealthy in microbial cultures and natural matter. That is good to make use of on vegetation of every kind to assist them flourish.
upcycle your plastic pots
It’s onerous to keep away from plastic pots with houseplants. As an alternative of tossing them out, disinfect them and save them for different gardening tasks. You could even be capable of return them to the nursery to allow them to be reused. Or verify and see in case your area people backyard has any want of them.
get native vegetation
Search for native plant swaps or backyard golf equipment in your space. They’re typically organized on-line, by way of social media, or by libraries. Different gardeners are sometimes joyful to offer you cuttings of their very own vegetation and may instruct you on suggestions to assist them thrive.
Do you could have a plant habit too? Will you be attempting out any of the following pointers? Let me know within the feedback beneath.
