Let There be Light:
How Much Light Does Boston Fern Plant Need to Thrive

Updated: March 26, 2023

Boston ferns are popular indoor plants that add a touch of greenery and beauty to any room. However, many people struggle to keep their Boston ferns healthy and happy due to not providing them with the right amount of light. In this article, we will explore how much light Boston ferns need to thrive and some tips on how to care for them.

Understanding the Light Needs of Boston Ferns

Boston ferns grow in their native habitat under the shade of tall trees in tropical rainforests. This means they prefer indirect, filtered light that mimics the conditions in their natural environment. Direct sunlight can damage their leaves and cause them to dry out. On the other hand, too little light can result in stunted growth and yellowing leaves.

In general, Boston ferns need about 12-16 hours of light per day to thrive. However, this does not mean they need 12-16 hours of direct sunlight. In fact, direct sunlight can be harmful to Boston ferns as it can cause leaf burn and make the plant susceptible to pests and diseases.

Tips for Providing the Right Amount of Light

Here are some tips for providing your Boston fern with the right amount of light:

  1. Place your Boston fern in a bright room but away from direct sunlight. If you have south-facing windows, consider placing your plant a few feet away from the window or use sheer curtains to filter the light.

  2. Rotate your fern regularly so that all sides receive equal amounts of light.

  3. If you live in a location with low natural light, consider using artificial lighting to supplement your plant’s needs. LED grow lights are an excellent option as they provide full spectrum light that mimics natural sunlight.

  4. Avoid placing your Boston fern near drafty doors or windows as they can dry out quickly under these conditions.

  5. Monitor your plant’s growth and adjust its lighting accordingly. If you notice your plant is growing too slowly or has yellowing leaves, it may be receiving too little light. Similarly, if you notice brown spots on the leaves or leaf burn, it may be receiving too much direct sunlight.

Other Care Tips for Boston Ferns

In addition to providing the right amount of light, here are some other care tips for keeping your Boston fern healthy:

  • Water your plant regularly but avoid overwatering it as this can lead to root rot. Allow the top inch of soil to dry out before watering again.

  • Mist your plant regularly with water to increase humidity around it. Boston ferns love humid environments and misting can help prevent dryness and brown tips on the leaves.

  • Fertilize your plant every 2-3 months during its growing season with a balanced houseplant fertilizer.

FAQ

Q: Can Boston ferns survive in low-light conditions?

A: While Boston ferns can survive in low-light conditions, they will not thrive and may develop yellowing leaves or stunted growth over time. It is best to provide them with at least 12-16 hours of filtered or indirect light per day.

Q: Should I mist my Boston fern every day?

A: You do not need to mist your Boston fern every day but misting it once or twice a week can help increase humidity around it and prevent dryness on the leaves.

Q: How often should I fertilize my Boston fern?

A: You should fertilize your Boston fern every 2-3 months during its growing season (spring and summer) with a balanced houseplant fertilizer. Avoid fertilizing during the winter months when growth slows down.

Q: How do I know if my Boston fern is receiving too much direct sunlight?

A: If your Boston fern is receiving too much direct sunlight, you may notice brown spots on the leaves or leaf burn. Move it away from direct sunlight and into a shaded area or use sheer curtains to filter the light.

In conclusion, providing the right amount of light is essential for keeping your Boston fern healthy and thriving. Remember to place it in a bright room away from direct sunlight, rotate it regularly, and monitor its growth for signs of overexposure or underexposure to light. With proper care, your Boston fern will add beauty and greenery to your home for years to come.
