The Lemon Button Fern, known scientifically as Nephrolepis cordifolia ‘Lemon Button,’ is a popular indoor plant appreciated for its vibrant foliage and compact size. However, like many tropical plants, it requires special care during cold weather to thrive. This article provides practical tips on how to handle cold snaps and protect your Lemon Button Fern.
Understanding the Cold Sensitivity of Lemon Button Fern
The Lemon Button Fern is sensitive to low temperatures, especially when temperatures drop below 50°F (10°C). Exposure to cold drafts, sudden temperature changes, or frost can cause leaf damage or even kill the plant. Recognizing these vulnerabilities is the first step in protecting your fern during cold weather.
Preparing Your Fern for Cold Weather
Preparation is key to ensuring your Lemon Button Fern survives cold snaps. Start by positioning the plant in a warm, draft-free location indoors before the cold weather sets in. If you keep the fern outdoors, consider moving it inside or to a protected area like a garage or porch.
Optimal Indoor Placement
Place your fern near a window with indirect sunlight, away from heating vents, radiators, or cold drafts. Maintaining a consistent temperature between 65°F and 75°F (18°C to 24°C) helps keep the fern healthy during winter months.
Using Protective Coverings Outdoors
If moving the plant indoors is not feasible, cover it with frost cloths or burlap when cold weather is forecasted. Elevate the plant slightly to prevent contact with cold ground and avoid water accumulation that can lead to root rot.
Watering and Humidity Tips During Cold Snaps
Adjust your watering schedule during cold weather. Water the fern only when the top inch of soil feels dry, as overwatering can lead to root rot in low temperatures. Maintaining higher humidity levels around the plant can also prevent leaf browning and stress.
Increasing Humidity
- Place a humidifier nearby.
- Use a pebble tray filled with water beneath the pot.
- Mist the foliage regularly, avoiding water accumulation on leaves.
Additional Tips for Cold Weather Care
Other essential tips include avoiding fertilizing during cold periods, as the plant’s growth slows down. Also, check regularly for signs of stress such as yellowing or browning leaves, and address issues promptly.
Monitoring and Adjusting
Keep an eye on weather forecasts and be prepared to take additional protective steps if a severe cold snap is predicted. Adjust your care routine accordingly to ensure your Lemon Button Fern remains healthy and vibrant throughout the winter.
Conclusion
Handling cold snaps effectively requires proactive measures and attentive care. By understanding your Lemon Button Fern’s needs and taking appropriate precautions, you can enjoy its lush foliage year-round, even during the coldest months.
