How to Keep Your Spider Plant Healthy During Winter—and Prevent Potential Problems

Spider plants are easy tropical houseplants known for their toughness, withstanding periods of drought and low natural light. However, as weather conditions change during winter and you crank up the heat in your home and less daylight is available, spider plants need a bit more attention to stay healthy and vibrant. Ahead, we consulted gardening experts who shared everything you need to know about keeping your spider plant thriving throughout the colder months.

Provide Enough Sunlight

Move your spider plant closer to a bright window, but not one that gets direct sunlight, such as an east- or north-facing window. Keep the plant slightly away from the window so it doesn’t get too cold, and make sure it is out of midday sun, as too much sunlight can result in scorched leaves, even in winter, says Morris Hankinson, managing director of Hopes Grove Nurseries. Rotate the spider plant every couple of weeks so it grows evenly. "If there isn’t much natural light available, grow lights can be helpful," he adds. 

Water Less Often

Be careful not to overwater the spider plant, especially if it's kept in a cool spot. "Roots are more likely to get stressed in wet soil," says Nastya Vasylchyshyna, the resident botany expert at Plantum. In cool, low-light environments, plants tend to slow their growth and need water less frequently and in smaller amounts. "Allow the topsoil to dry out between watering sessions and choose a pot with drainage holes at the bottom so excess water can drain freely," she says.

Keep Humidity High

Even in winter, the spider plant thrives in moderate to high humidity. "In winter, keep it away from heating appliances, as they dry out the air," Vasylchyshyna says. To increase humidity, consider using a plant humidifier or relocating the plant to areas of the home with higher moisture, such as the bathroom. Grouping your houseplants, placing a container filled with water nearby, and occasionally misting the leaves with a fine sprayer can also increase the humidity around the plant, Vasylchyshyna adds. 

Stop Fertilizing

Do not fertilize your spider plant in winter. "Feeding during dormancy can burn roots and create weak, leggy growth," says Adrian Aviles, owner of the Athletic Club Flower Shop. The spider plant doesn't grow much, if at all, during winter due to cooler temperatures and reduced light, so fertilizing isn't necessary. Instead, wait until spring when new growth appears to resume fertilizing. 

Avoid Cold Drafts and Heat Sources

Keep plants away from drafty windows, doors, radiators, and vents during winter. "Sudden temperature swings stress spider plants and can cause leaf damage even if watering is correct," says Aviles. Temperatures between 60 and 75 degrees Fahrenheit are ideal for spider plants, says Hankinson.

Signs Your Spider Plant Is Struggling 

In addition to following the above advice, keep your eyes peeled for some of the warning signs your spider plant may be in danger in winter. Here are some red flags to watch out for.

Wilted Leaves

Pale and wilted foliage, as well as stunted leaf growth, may indicate that the spider plant lacks sunlight, says Vasylchyshyna. If you see these warning signs, move your plant closer to a window or use a grow light to increase light exposure.

Yellowing Leaves

Yellow leaves are most likely the result of overwatering or poor drainage, says Hankinson. Let the soil dry more between waterings and check that drainage holes aren’t blocked if you spot this warning sign.

Browning Tips

Brown leaf tips often signal low humidity, Vasylchyshyna warns. The damaged parts won’t recover, but increasing the humidity will prevent new leaves from drying at the edges. Then remove the leaves with brown tips, allowing the plant to focus on the healthy parts of its foliage.
