Growing Ferns Indoors
Understanding Ferns
Ferns, one of the oldest groups of living things on earth, date back over 300 million years and currently include more than 10,000 living species (Brooklyn Botanic Garden). These non-flowering houseplants are primarily grown for their diverse and attractive foliage. Key varieties typically grown indoors include the Caterpillar Fern, Lacy Rabbit’s Foot Fern, Bird’s Nest Fern, Japanese Holly Fern, and Button Fern.
Ferns are vascular plants that reproduce by spores rather than seeds. Native to tropical rainforests, they thrive in environments with indirect sunlight, moist soil, and high humidity (UConn Home and Garden Education Center). Starting with some common and easily adaptable species can be a good way to begin growing ferns as houseplants.

Care Tips for Indoor Ferns
To thrive, an indoor fern plant in a pot requires proper care and attention. This section outlines essential tips for maintaining the health and vibrancy of your ferns indoors.
Light and Temperature Requirements
Fern plants generally prefer indirect light, as direct sunlight can scorch their delicate fronds. Placement near a north or east-facing window is ideal for most fern varieties (Brooklyn Botanic Garden). Here are the typical light and temperature needs for indoor ferns:
| Light Requirement | Temperature Range |
|---|---|
| Indirect Light | 60-75°F (15-24°C) |
For specific light requirements of various ferns, visit our page on fern plant light requirements. Maintaining consistent temperatures is crucial. Avoid placing ferns near drafty windows or heat sources that could cause temperature fluctuations. For more details on temperature tolerance, check out fern plant temperature tolerance.
Watering and Humidity Needs
Watering is perhaps the most critical aspect of fern care. Fern plants enjoy consistently moist soil but dislike waterlogged conditions. Water your fern when the top inch of soil feels dry. Humidity is another important factor. Ferns flourish in environments with high moisture levels, ideally between 40-50% relative humidity (Brooklyn Botanic Garden).
| Requirement | Ideal Condition |
|---|---|
| Soil Moisture | Moist, well-drained |
| Humidity | 40-50% |
In overly dry environments, consider using a humidifier or placing a tray of water near the fern to maintain adequate humidity. For tips on fern plant watering, refer to our detailed guide.
Fertilizing and Feeding Ferns
Ferns typically extract nutrients from decaying organic matter in their natural habitat. While they can survive without fertilizing, applying a layer of compost in the spring can boost their growth.
For regular fertilizing:
- Use a slow-release, well-balanced 10-10-10 fertilizer. Avoid fertilizers higher than 15-15-15, as they can harm the ferns.
- During active growth periods, a liquid houseplant fertilizer at half the recommended amount is sufficient. Over-fertilization can cause foliage scorching.
- Newly divided or repotted ferns should not be fertilized for six months.
These general guidelines can help ensure your indoor ferns remain healthy and lush. For additional information on fern care, visit our fern plant care page. Should you encounter any issues, our troubleshooting guide for fern plant dying may provide helpful insights.

Repotting and Propagation Techniques
Repotting Ferns
Repotting ferns might be necessary if the plant outgrows its pot or if the soil medium depletes nutrients. Follow these steps for successful repotting:
- Choose the Right Pot: Select a pot that is 1-2 inches larger in diameter than the current one, ensuring it has drainage holes (Brooklyn Botanic Garden).
- Prepare the Soil: Use a well-draining fern potting mix. Avoid using heavy garden soil.
- Remove the Fern: Gently remove the fern from its current pot, being careful not to damage the roots.
- Inspect the Roots: Trim any dead or rotting roots.
- Repot: Place the fern in the new pot and fill in with soil, making sure the root ball is covered while ensuring the plant sits at the same depth as before.
Propagation Techniques
Propagating ferns can be done through two primary methods: spores and division.
Using Spores:
- Collect Spores: Collect spores from the underside of mature fronds.
- Sow Spores: Scatter the spores on a moist, sterile potting mix.
- Maintain Humidity: Cover with plastic to maintain moisture and place in indirect sunlight.
Division:
- Divide the Rhizomes: Carefully divide the fern’s root ball into sections with a sharp knife.
- Plant the Divisions: Each section should have a portion of roots and fronds. Pot each division in separate pots with damp potting mix.
