The Q&A Archives: How do I take of ferns indoors

Question: For the summer I had some potted ferns outside on my deck when it started getting cold I brought them inside. Now my question is do I water it with warm water the temperature of my house drops to 55 degrees when we are at work during the day and will it be okay without direct sunlight? Also, how often and do I I give it plant food.

Answer: There are a few exceptions, but most ferns will adapt to growing indoors. Give them bright light but not direct sunlight. Ferns will tolerate a temperature of about 50 degrees but their growth will slow when temperatures are low. Use tap water or room temperature water - not warm water - when watering them. Since growth will be slow during the winter months, don't fertilize at all. In the springtime you can take them back outdoors and lightly feed them with a half-strength dilution of liquid fertilizer (such as Miracle Gro or Peter's).

Best wishes with your ferns!
