Gardening expert’s guide to wintering houseplants

Silver Spence, CEO of independent houseplant site Friends or Friends, shared his guide to overwintering houseplants with, ready for the darker and colder months to come. As the winter months arrive, the plants need water and temperature adjustments. Chills, dry air, and lack of sunlight can all have a huge impact on houseplants this time of year.


Humidity is especially important for some houseplants like ferns, monsteras, and spider plants.

Heating in winter means the air is often dry and drafts, which are not ideal conditions for a houseplant.

Owners of indoor plants will need to create a microclimate by regularly increasing the humidity of the plants.

Silver explained, “You can do this by grouping your plants together, placing them on a pebble tray, or purchasing a humidifier that suits your space.

“The most important thing is that they are constantly wet and not just in relays.

“If you can’t humidify for fear of damaging your home, a bell or mini greenhouse / cabinet is ideal.


Silver said heating is bad for plants, but it can also help.

Cold homes or particularly cool rooms are not ideal for plants, so houseplant owners may need to consider a heating pad.

These can be purchased from reptile stores or online as seed germination material.

Silver added, “Heating pads and lamps will provide the constant warmth that tropical plants need to survive.

“If your heat, humidity, and light are all aligned, your plants can continue to grow through the winter.”

Let’s remember…

Silver said there are two key things houseplant owners should remember when wintering houseplants.

She said, “Plants are living things. Some plants need periods of dormancy and seasonal changes.

“In nature, plants will have wet and dry seasons – they will have a darker winter and a colder, darker night.”

Silver’s top tips:

– Never leave grow lights on 24/7.

– Provide the appropriate amount of water. Lower temperatures and light = less need for water.

– Remember to ventilate the space as this will be crucial for the health of the roots.
