Guide to Indoor Plant Temperature | Blossom As with all other forms of life, houseplants have temperature requirements. These must be satisfied for their survival and flourishing. Many plants can endure temperatures as low as 40 degrees Fahrenheit, while 60 degrees Fahrenheit is preferred by most.
What is the minimum temperature a houseplant can withstand?
Light In winter, the sun sinks lower in the sky, reducing the amount of light near windows by up to 50 percent. In the winter, houseplants that thrive near an eastern or northern window in the summer may require a southern or western exposure. Similarly, plants near windows facing the west or south that require filtered light in the summer may be able to endure direct sunlight in the winter.
- To assist plants in adapting to varying light levels: If feasible, move plants closer to windows.
- Windows should be spotless for optimal light transmission.
- For the winter, relocate plants to new areas near brighter windows.
- Remove dust from plants so that their leaves can make most use of available light.
Bring in artificial light. Fluorescent lamps offer ample light. They are less expensive than conventional grow lights and emit less heat. Place bulbs four to twelve inches away from plants for optimal results. Temperature The majority of houseplants are tropical and enjoy daytime temperatures between 65 and 75 degrees Fahrenheit and nighttime temps 10 degrees colder.
For many plants, temperatures below 50 degrees Fahrenheit might be problematic. Adjust thermostats for your comfort, but keep in mind that your plants require care. Avoid planting plants near drafts or sources of heat. Keep vegetation a few inches away from windows. If windows frost overnight in chilly locations, pull plants away from windows at sundown.
Additionally, you may place a thick shade or other insulating material between the plants and the glass. Humidity During the winter, indoor relative humidity may range from 5 to 10%. Houseplants like 40-50%. Brown leaf tips and the emergence of pests such as spider mites are symptoms of low humidity stress on plants.
- Discover simple methods for increasing humidity around plants.
- Water Winter’s most prevalent concern for houseplants is overwatering.
- Approximately 95% of houseplants require nearly total soil drying before watering.
- How can you know if plants require water? Don’t just spot test the soil surface.
- If the root zone is dry, plants require water.
Insert your finger up to 2 inches into the earth. Water the soil if it is dry. Lift the kettle. Dry soil is lighter than wet soil. Learn how damp soil feels by quickly lifting pots after watering. If you humidify winter spaces, plants will require less watering.
- Dry air need irrigation.
- Citrus and ferns in containers are exceptions to the rule that soil must dry out between waterings.
- If uncertain, always investigate plant moisture requirements.
- Never leave plants to sit overnight in water that gathers in the drainage saucer after you water them.
- Fertilizer In mild areas, fertilize plants throughout the winter.
In the coldest areas when natural light levels are low, winter is not the time to nourish indoor plants. When outside plants awaken in spring, you should resume fertilization. Prune Winter vegetation can be slender. To promote branching and bushiness, pinch plants.
- Repot Most houseplants should be repotted during active growth times, namely spring and summer.
- The exception is woody plants in containers that go entirely dormant over the winter.
- These should be planted prior to the bud break in early April.
- More about Indoor Plants There are several benefits of houseplants, including increasing indoor air quality and preventing illness.

The majority of our houseplants like temperatures that are pleasant for humans. A temperature range from 60 degrees at night to 75 degrees during the day is acceptable. Now that we have lowered the thermostat and temperatures are not as cozy as we would like, what about the plants? Actually, the most of them will not suffer terribly.
In addition, there are ways to alleviate stress. If you have dropped the temperature from the usual 70 or 75 degrees (or even higher) during the day to 65 degrees during the day and 55 degrees at night, as we have been instructed to do, some of your plants may lose leaves or enter a “holding pattern” in which they do not grow.
However, if temperatures remain below 60 degrees for an extended period of time, plant development will be stunted and they may not recover. If your office is kept between 40 and 45 degrees Fahrenheit during lengthy weekends, plants will suffer, particularly blooming species.
Tropical plants such as dracena, schefflera, philodendron, and ficus would be negatively impacted. Let’s examine a few of the problems you’ll face and discuss what you may do to relieve them. From the window to the radiator, temperatures might change by as much as 20 degrees within the same room. Check this and, if necessary, provide warmer housing for the plants.
Closer to windows, plants will experience a cooler nighttime temperature than plants located elsewhere in the room. In extreme cold, as we have just had, it is best to move plants away from windows, put curtains between plants and window panes, or place cardboard or newspaper between plants and window panes at night.
The leaves must not contact the window glass. Even if the entire plant is not frozen, one leaf will be lost. Do not place plants in front of hot air radiators or space heaters if you wish to relocate them away from windows to a warmer location. Also, keep in mind that the heat from incandescent bulbs such as those used in table and desk lamps might cause leaves to burn.
When you can feel the warmth of the light on the back of your hand when you place a plant beneath such a light, the plant is near enough. Avoid drafts and chilly air blasts caused by regularly opened doors. Move plants away from entrances with constant foot traffic.
With lower temperature and slower plant development, plants require less water to survive. Probably, watering will need to be decreased. The majority of foliage plants will not be harmed by a nighttime temperature of 50.55 degrees. Even cooler are geraniums, small roses, strawberry begona (saxifraga), ivy, wandering jew, and a few cactus.
The nighttime temperature for gloxinias, African violets, and other gesneriads should never go below 60 degrees. Perhaps you can construct a protected cage in which these plants can benefit from any nighttime heat provided by your heating system. The optimal development of a plant in relation to temperature varies on the origin of the plant.
- The majority of our indoor plants originate from nighttime-cooling heights in warm areas.
- When the lights go down at night in homes and offices, a temperature decrease of 10 degrees is welcome; in fact, it is required since nighttime growth activities do not require as much heat as daytime processes.
When a plant is dormant, resting or not actively developing, a nighttime temperature of 60 degrees is sufficient. The majority of our foliage houseplants are dormant throughout the short, frequently cloudy days of winter. As a result, unless the low temperature is extreme and prolonged, your plants will do nothing except wait for the weather to warm up, just as the rest of us have been doing for the previous few weeks.
Should I cover my plants while the temperature is 39 degrees?
When Should Plants Be Covered? – Cover your plants at night and remove them during the day when temperatures reach above 32 degrees Fahrenheit to allow the soil to rewarm. Some outside plants will not survive the severe winter temperatures; move them inside and follow these winter care instructions. through amazon.com
To assist houseplants acclimate to their new environment, group related types together. If you have an underutilized south or west-facing space in your home, relocate all of your plants there. As mentioned previously, you may then utilize a smart thermostat or smart AC controller to maintain their appropriate temperature.
Will my plants survive temperatures of 45 degrees?
What Temperature Is Too Cold? – When it comes to houseplants, some enjoy it hot (particularly tropical plants like Hibiscus rosa-sinensis), but practically all plants require at least warm temperatures. So, at what temperature must indoor plants be brought indoors during the summer? 45 degrees Fahrenheit is the temperature that must be monitored.
