Why Temperature Matters

Temperature plays a vital role in the health of your Boston fern. Too cold, and you risk leaf damage or plant death. Too hot, and your fern may become stressed and droopy. By maintaining the right temperature, you’re ensuring:

  2. Lush, vibrant fronds
  3. Resistance to pests and diseases

Protecting Your Boston Fern from the Cold

When the mercury drops, it’s time to take action. Here are some tried-and-true methods to keep your fern cozy:

Cover Them Up

If you’re experiencing a cold snap, consider these options:

  1. Frost blankets: These breathable covers protect against light freezes.
  2. Bubble wrap: An excellent insulator for potted ferns.

Remember to remove coverings when temperatures rise to prevent condensation buildup.

Bring Them Indoors

For a foolproof solution, bring your Boston ferns inside when temperatures consistently drop below 10°C (50°F). Here’s how to make the transition smooth:

  1. Choose a bright, indirect light location
  2. Maintain high humidity with a pebble tray or humidifier
  3. Continue regular watering, adjusting for indoor conditions

Winter Fertilization

Don’t forget about nutrition! Even in winter, your fern needs a little boost:

  • Use a balanced, water-soluble fertilizer
  • Apply monthly at half-strength
  • Always water before fertilizing to prevent root burn
