If you're new to the world of houseplants, you might be surprised to learn that your leafy companions are a lot like you when it comes to temperature. Most houseplants are comfortable in the same temperature as us—between about 65°F and 80°F during the day, a few degrees cooler at night. Understanding your houseplants’ temperature needs is one of the easiest ways to keep them happy and healthy.

Why Temperature Matters

Most of our common houseplants come from tropical or subtropical regions, which means they’re adapted to warm, stable environments. When temperatures dip too low or spike too high, your plants can suffer. They can't just put on a sweater if they feel a chill. Cold drafts, heatwaves, and even the placement of your plants near windows or vents can make a big difference in their well-being.

Tips for Managing Temperatures Indoors

Keep It Consistent: Avoid placing your plants near drafty windows, exterior doors, or heating/cooling vents. Sudden temperature swings can stress your plants, even if the average room temperature is ideal.

Don't Stress Over Heatwaves: During summer, indoor temperatures can rise quickly—especially near sunny windows. If your plant’s leaves start to curl or wilt, it might be too warm. Move it a few feet back from the window or draw sheer curtains to soften the heat.

Protect from Drafts: In winter, cold air seeping through windows or doors can chill your plants. Blasts of hot air from a heating vent can also stress your plant. After all, in nature, plants aren't usually exposed to drafts that are noticeably warmer or cooler than the ambient air temperature. 

Let Your Plants Tell You: Your plants will often show signs if they’re too hot or cold. Drooping, yellowing, or scorched leaves can all be indicators of temperature stress. Pay attention to these cues and adjust their environment accordingly.
