The first thing to remember when growing Boston ferns is that they are not native to the United States, but are actually from South America. This means they need much more light than the average houseplant and would do better outside. That being said, if you can't place your plant outdoors because of climate or other reasons, there are still some easy things you can do to help maximize their health and lifespan while indoors.
Boston Ferns are one of the most popular houseplants. They are easy to care for and can survive with minimal sunlight. In the Boston area, a Boston fern needs about 4-6 hours of sunlight each day. In other areas, this number will vary so it is important to ensure that there is at least one hour of direct sunlight every day.
However, if you’re in a sunnier place it needs about four hours of direct sunlight daily, so they should be placed in an east-facing window or near a south-facing window.
The roots need to be watered two to three times a week for healthy growth. The soil should not be allowed to dry out completely, but it is important that it does not stay wet for too long either. It is important that the Boston Ferns are not placed near any vents because they can dry out quickly due to hot air being blown over them 24/7.
