Spider Plant Temperature Tolerance: How Hot Is Too Hot?
Learn to maintain your spider plant's health by understanding its temperature tolerance and recognizing the subtle signs of heat and cold stress.
The spider plant, or Chlorophytum comosum, is a popular and resilient houseplant, favored for its adaptability and graceful, arching leaves. Its reputation for being easy to care for makes it a common sight in homes and offices. Understanding the temperature preferences of this plant is fundamental to ensuring it prospers and maintains its vibrant appearance.
Optimal Temperature for Spider Plants
Spider plants flourish within a temperature range that mirrors their native tropical habitats in Africa. The ideal indoor climate is consistently between 60°F and 75°F (15°C to 24°C). Maintaining temperatures in this zone encourages strong growth, supports vibrant leaf variegation, and promotes the production of small plantlets, or “spiderettes.”
While tolerant of conditions slightly outside this range, these temperatures are where they perform best. This moderate climate allows the plant’s metabolic processes to function efficiently without the stress induced by extreme cold or heat.
Recognizing and Preventing Cold Damage
Although adaptable, spider plants have a lower temperature limit. They can tolerate temperatures as low as 35°F (2°C) but are not frost-tolerant. Exposure to frost will cause severe cellular damage that can be fatal. Move any outdoor spider plants inside before the first frost is forecasted.
When a spider plant is exposed to cold, it will show clear signs of distress. The leaves may take on a water-soaked appearance before turning dark brown or black, and affected leaves will become soft and mushy. To prevent this, keep indoor plants away from drafty windows and doors during colder months, as consistent exposure to cold drafts can lead to chronic stress.
Managing High Heat Stress
Just as spider plants have a low-temperature threshold, they also have an upper limit. They can manage temperatures up to 85-90°F (29-32°C), but prolonged exposure to heat beyond this range will induce stress. One of the first signs of heat stress is wilting, as the plant loses moisture faster than its roots can absorb it. The leaves may also appear faded or pale.
If high heat is combined with direct sunlight, the leaves can become scorched, resulting in brown, dry patches and crispy leaf tips. To manage these conditions, move the plant to a location with bright, indirect light. Ensure the soil remains consistently moist but not waterlogged. Good air circulation can also help dissipate heat around the plant.
