Indoor Houseplant Care · Canada
Keeping plants healthy through long Canadian seasons.
Homes here swing from bright summer windows to short, dry winter days with the furnace running. These guides cover how to read light, time watering, and choose species that handle indoor conditions.

Guides
Three starting points for indoor growers.
Each guide focuses on conditions common in Canadian apartments and houses, from north-facing rooms to dry winter air.
Watering Indoor Plants
How to replace fixed calendars with checks based on soil, pot, and season, with a simple reference table by plant type.

Low-Light Houseplants
Species that tolerate north windows and interior rooms, plus how to tell low light apart from no light.

Fundamentals
The conditions that decide most outcomes.
Light direction
A south window in Toronto delivers far more winter light than a north window. Match a plant's needs to the brightest spot it can reach, not the room's average.
Indoor humidity
Forced-air heating can pull indoor air well below the 40–60% many tropical foliage plants prefer. Grouping pots or using a tray of water helps locally.
Watering rhythm
Most root problems trace back to watering on a fixed schedule. Check the top few centimetres of soil and the pot's weight before adding water.
Pot and drainage
A drainage hole and a saucer you empty matter more than pot material. Standing water is the fastest route to root rot indoors.
Seasonal rest
Shorter days mean slower growth. Feeding and frequent watering during the rest period often does more harm than skipping them.
Steady temperature
Cold drafts from single-pane windows and dry heat from radiators both stress foliage. A stable spot away from both is usually best.
At a glance
A quick seasonal reference.
General patterns for foliage houseplants in a typical Canadian home. Adjust to your own rooms and species.
spring light increases · resume feeding · repot if root-bound
summer brightest months · water checks more often · watch for pests
autumn light fades · reduce feeding · move plants closer to windows
winter shortest days · water sparingly · raise local humidity · rest
