About National Houseplant Appreciation Day
Houseplant Appreciation Day is marked on 10 January. In 2027 it falls on Sunday, 10 January 2027. It was created by an American gardening website, The Gardener's Network, as a nudge to look after indoor plants in the flat, dark week after the holiday decorations come down. It has no official status in India or anywhere else.
Houseplant Appreciation Day is a small invented day with an honest reason behind it. January is when indoor plants quietly die, and somebody decided to put a reminder on the calendar.
What is Houseplant Appreciation Day and who marks it?
Houseplant Appreciation Day is an observance on 10 January created by The Gardener's Network, an American gardening website. It is not a government or UN day, and it has no traditional following in India.
The reasoning the creators give is practical. By the second week of January the festive decorations are down, rooms look bare, and houseplants that were ignored through a busy December start to show it. The site also points out that it is properly called Houseplant Appreciation Day, and that the "National" prefix was added later by other websites.
Who actually marks it: nurseries, plant shops and plant accounts on social media, mostly in the United States and Britain. In India, if you see it at all, it will be a garden centre offer or a post from a plant seller.
Do houseplants clean the air?
Not in any useful amount. This is the most repeated claim about indoor plants and the evidence does not support it.
The belief comes from a NASA study published in 1989, which tested plants in small sealed chambers and found they removed volatile organic compounds. In 2019, Michael Waring and Bryan Cummings of Drexel University re-analysed about a dozen studies covering thirty years of this research and published the result in the Journal of Exposure Science and Environmental Epidemiology. Their finding was that ordinary ventilation clears those compounds far faster than plants can absorb them. To match a normal building's air exchange, you would need somewhere between 100 and 1,000 plants per square metre of floor.
Keep plants because you like them, because a room feels better with something alive in it, and because looking after something is good for you. Those are real reasons. Air purification is not one.
How do you look after houseplants in an Indian January?
Water less, not more. Light levels and temperatures drop, plants grow slowly, and the compost should be barely moist rather than wet. The Royal Horticultural Society advises limiting feeding to about once a month in winter, since plants cannot use fertiliser in low light.
Three things specific to India in January:
- In the north, night temperatures can fall below 10°C. Most popular indoor plants are tropical and sulk or rot at those temperatures. Bring balcony pots inside at night and keep them off cold stone floors and away from draughty windows.
- In the south and along the coasts, January is mild and dry. The bigger risk there is dust on leaves cutting the light. Wipe them with a damp cloth.
- Do not repot in January anywhere. Wait for active growth, which in most of India means late February onwards.
| Plant | Light it needs | Watering in January | Common mistake |
|---|---|---|---|
| Money plant (pothos) | Bright indirect; survives low light | Only when the top layer of soil is dry | Leaving it in a water bottle for years with no feed |
| Snake plant | Low to bright; very tolerant | Once every two to three weeks at most | Overwatering, which rots the base |
| Areca palm | Bright indirect | Keep barely moist, never soggy | Cold draughts browning the leaf tips |
| Peace lily | Low to medium | When the leaves just begin to droop | Direct afternoon sun scorching the leaves |
| ZZ plant | Low light is fine | Once a month is usually enough | Treating it like a thirsty plant |
Tulsi sits outside this list. In many Indian homes it is grown in a courtyard or balcony as a sacred plant and given water and prayers rather than decor duty, and treating it as a houseplant misses the point of it.

Frequently asked questions
When is National Houseplant Appreciation Day in 2027?
National Houseplant Appreciation Day 2027 falls on Sunday, 10 January 2027.
Who created Houseplant Appreciation Day?
It was created by The Gardener's Network, an American gardening website, which set 10 January as the date. The site notes that its own name for the day is Houseplant Appreciation Day, and that the "National" prefix was added later by other websites.
Why is Houseplant Appreciation Day on 10 January?
The date was chosen for the flat week after the holidays, when decorations come down, rooms look bare and plants neglected through a busy December start to show stress. It is also the middle of winter in the country where the day was created, long before outdoor gardening restarts.
Is Houseplant Appreciation Day observed in India?
It has no traditional or official standing in India. Any activity on 10 January comes from nurseries, plant shops and social media accounts, not from any Indian custom or government observance.
Do houseplants really purify indoor air?
No, not in a meaningful way. A 2019 Drexel University review of about a dozen studies found that normal ventilation removes volatile organic compounds far faster than plants can, and that matching it would take roughly 100 to 1,000 plants per square metre of floor space.
How often should houseplants be watered in winter?
Less often than in summer. In low light and cooler temperatures plants grow slowly, so the compost should be kept barely moist, and many plants can go one or two weeks between waterings. Overwatering, not underwatering, kills most indoor plants in winter.
