A House Beautiful report recommends four changes to houseplant care during autumn and winter: move plants toward brighter light while avoiding drafts, water and feed less as growth slows, group plants to support humidity, and wipe dust from leaves. The advice is attributed to Mark Sage, B&Q’s horticulture expert; specific needs vary by plant and home conditions.
House Beautiful has outlined four changes to make to houseplant care in autumn and winter, with advice from Mark Sage, B&Q’s horticulture expert. The recommendations address lower daylight, cooler conditions and drier indoor air: adjust plant placement, reduce watering and feeding as growth slows, group plants, and clean dust from their leaves.
Sage advises moving houseplants closer to a bright window as days grow darker, but not placing them where they face cold drafts or hot, dry air from radiators. He says those conditions can harm plants. Where daylight remains limited, a plant light may provide additional light, and rotating larger plants can help prevent uneven growth as they reach toward a light source.
Watering and feeding should change along with growth. Sage says plants generally need less water and fertilizer during a slower winter growth period, and advises allowing soil to dry between waterings to reduce the risk of root rot. He recommends a final dose of plant feed at the end of autumn and says winter is not the time for regular repotting.
The other suggestions focus on indoor air and leaf care. Grouping plants can create a more humid area around them, which may help when central heating dries the air. Sage also recommends wiping leaves with a microfibre cloth every one to two weeks so dust does not obstruct the limited winter light reaching them. A gentle shower with lukewarm water can remove dust and pests, but he cautions against water that is too cold or too hot.
Winter Conditions Change Plant Care
The advice matters because a summer routine may not suit plants when daylight and growth decrease and indoor heating changes the air. Continuing to water or feed at the same rate can be inappropriate for plants growing more slowly; Sage specifically advises letting soil dry between waterings to help prevent root rot.
Placement also involves a trade-off: a brighter window can provide needed light, but nearby cold drafts or radiator heat may expose a plant to conditions Sage warns can cause damage. The recommendations offer practical adjustments for common household conditions, rather than a single schedule that applies to every plant.

Why Autumn Care Routines Shift
The report frames winter care around three changes: shorter daylight, cooler temperatures and drier indoor air. Many houseplants are kept indoors through the colder months, but their growth can slow, changing how much water and feed they need. Central heating can also make indoor air drier, while window areas may be exposed to cold drafts.
Sage’s guidance is presented as general advice for houseplants, including tropical varieties such as spider plants, peace lilies and monsteras. The supplied report does not provide plant-by-plant instructions or describe a scientific study; its recommendations are attributed to Sage as a horticulture expert.
““It’s always a good idea to move them closer to a bright window as darker days hit, but make sure to avoid cold drafts and radiators.””
— Mark Sage, B&Q’s horticulture expert, speaking to House Beautiful
Advice Varies by Plant and Home
The report does not specify how much to reduce watering or provide a universal schedule. That depends on the plant and its conditions; the source’s general instruction is to let soil dry between waterings during slower growth. It also does not identify a particular light level, temperature range or humidity target.
No independent study or plant-specific evidence is included in the supplied material, and the effects described are attributed to Sage. Readers should not assume every plant responds identically to grouping, cleaning or reduced feeding. The report also does not say how to identify the needs of individual varieties.
Adjust Care Through Winter
The immediate next step is to check each plant’s position, growth and soil rather than follow a summer routine automatically. Move plants toward suitable natural light while keeping them clear of cold drafts and direct radiator heat; observe whether the soil has dried before watering, and avoid routine winter repotting.
Houseplant owners can also try grouping plants and wiping leaves every one to two weeks, then watch how their plants respond as conditions change. The supplied report does not announce a follow-up study or further guidance. Its advice is presented as a seasonal routine to use through autumn and winter, with adjustments based on individual plants and the home.
Key Questions
How often should I water houseplants in winter?
The report gives no fixed schedule. Sage advises watering less as growth slows and letting the soil dry between waterings to help prevent root rot. Check the soil and account for the plant and its conditions rather than relying on a summer timetable.
Where should I place houseplants during winter?
Sage recommends moving plants closer to a bright window as daylight decreases, while avoiding cold drafts and hot, dry air from radiators. A plant light may help where natural light is limited.
Should I feed or repot houseplants in winter?
The report says plants generally need less feeding during slower growth and advises against regular winter repotting. Sage recommends giving plants their final feed at the end of autumn.
Why group houseplants together?
Grouping plants can create a more humid microclimate around them, according to Sage. The report says this may be useful when central heating makes indoor air drier.
How should I clean houseplant leaves?
Sage recommends wiping leaves with a microfibre cloth every one to two weeks. He also suggests an occasional gentle shower with lukewarm water, cautioning that water that is too cold may shock roots and water that is too warm may scald leaves.
