Growing Ferns Inside

By Ashleigh Smith

Growing ferns inside can be tricky if you don’t understand what conditions they like. Ideally ferns like a humid, dappled light, constant environment. Changing temperatures and light conditions quickly will result in a less appealing appearance and weak growth. Naturally ferns are found in two types of climates, tropical and temperate.

In a tropical climate ferns enjoy medium light (east facing windows or a few feet away from west or south windows). When watering tropical ferns use lukewarm or room temperature water. They should also only be fertilized when active growth is happening. To prevent issues with bugs indoors make sure you keep the leaves clean by dusting and washing with a spray of water, or swish in a sink or tub of water with a few drops of dishwashing liquid.

Temperate ferns tend to like the cooler areas of the home. They will also struggle in areas that are kept too warm so be aware of your placement in relation to heaters and air vents. While temperate ferns can be placed in cooler areas of the home, they will need special accommodations to maintain higher humidity levels. Simply keep a humidifier near your fern.
