House Beautiful reports that shorter days, cooler temperatures and drier indoor air can change what houseplants need in autumn and winter. B&Q horticulture expert Mark Sage recommends adjusting plant placement, reducing watering and feeding, grouping plants to support humidity, and cleaning leaves every one to two weeks.
House Beautiful has outlined four winter care habits for indoor plants, drawing on advice from Mark Sage, B&Q’s horticulture expert. The recommendations address shorter daylight, cooler temperatures and drier air indoors, which can make a summer watering and placement routine less suitable for plants during autumn and winter.
Sage recommends moving plants closer to a bright window as days become darker, while keeping them away from cold drafts and radiators. He says those conditions can harm plants; the report lists yellowing leaves and root rot among potential problems. Where natural light is limited, Sage suggests considering a plant light. He also says rotating larger plants daily can help limit uneven, stretched growth as they reach toward sunlight.
The report’s second habit is to water and feed less as growth slows. Sage says plants generally need less water and fertilizer during their slower growth period, and advises letting soil dry between waterings to reduce the risk of root rot. He recommends a final dose of plant food at the end of autumn and says winter is not the time for regular repotting.
For humidity, Sage advises clustering plants together so they can create a more humid microclimate, particularly when central heating dries indoor air. He also recommends wiping dust from leaves with a microfibre cloth every one to two weeks, which the report says helps leaves make better use of limited winter light. A gentle shower with lukewarm water can remove dust and pests, but Sage warns that water that is too cold may shock roots and water that is too warm may scald leaves.
Why Winter Changes Plant Care
The advice matters because seasonal conditions alter how houseplants use water and light. Continuing a summer routine without adjustment may leave soil wet for longer while plants grow more slowly, increasing the risk of root problems. At the same time, darker days can limit the light available to plants, and indoor heating can lower humidity.
The suggested changes are practical adjustments rather than a single treatment for every plant: placement, watering and humidity all affect the conditions around a plant. The report’s guidance can help readers review common household routines, but it does not claim that the same schedule or setup will suit every species or home.

The Four Seasonal Adjustments
The report frames winter as a period when many indoor plants enter slower growth, not as a time to encourage new growth with extra water or feeding. Sage’s advice is to let plants rest, avoid routine winter repotting, and give any final autumn feeding before the colder season is underway.
The four habits are to improve access to natural light without exposing plants to drafts or radiator heat; reduce watering and feeding; group plants to support humidity; and remove dust from leaves regularly. House Beautiful identifies reduced daylight, cooler temperatures and dry indoor air as the seasonal factors behind those recommendations.
“Sometimes the best thing you can do for your plants is leave them alone!”
— Mark Sage, B&Q’s horticulture expert, as quoted by House Beautiful
What Varies Between Plants
The report does not provide species-by-species watering schedules, precise light requirements or humidity targets. It also does not specify how much a plant should be rotated or how long it should remain near a window. The recommendations are attributed to Sage as general seasonal guidance; the source does not report testing or quantify how much each habit changes plant health.
Conditions also differ between homes and individual plants. The report does not establish that every houseplant needs the same changes, so its advice should not be read as a fixed care calendar for all varieties.
Adapting Care Through Winter
As colder weather and shorter days continue, the report recommends monitoring indoor conditions and adjusting routines accordingly: check whether a plant is near a draft or radiator, let soil dry between waterings, and clean dusty leaves regularly. Sage also advises watching water temperature if giving plants a shower.
The article sets out no follow-up study or scheduled update. Readers can use the four habits as seasonal prompts, while observing how their own plants respond and accounting for differences in species, light and indoor conditions.
Key Questions
How often should houseplant leaves be cleaned in winter?
Mark Sage recommends wiping leaves with a microfibre cloth every one to two weeks to remove dust and help plants use available light.
Should I water houseplants more in winter?
The report advises watering less as growth slows. Sage recommends letting the soil dry between waterings to help prevent root rot; it does not give a universal schedule for every plant.
Where should I put houseplants during winter?
Sage suggests moving plants closer to a bright window, while keeping them away from cold drafts and radiators. A plant light may be an option where natural light is limited.
Does grouping houseplants help in winter?
Sage says grouping plants can create a more humid microclimate, which may help when indoor heating makes the air drier.
Should I fertilize or repot houseplants in winter?
Sage says plants generally need less feeding during slower winter growth and advises a final dose at the end of autumn. He says winter is not the time for regular repotting.
