Light Requirements
Hare's Foot Fern grows best in bright, indirect light. Keep it away from direct sunlight as it may scorch the fronds.
Rotate the pot regularly to ensure that the fern receives light on all sides for even growth.
Davallia canariensis can also grow under a grow light where natural light is not adequate.
Watering
Water Hare's Foot Fern liberally during the growing season and allow the top 1-2 in. of soil to dry out between waterings to keep the soil consistently.
Cut down on watering during cold season as growth is minimal at this time to keep the soil slightly moist but do not let the soil dry out completely. Maintain the rhizomes moist by daily misting.
Ascertain that the pot has a drainage hole to prevent the soil from getting soggy as it can lead to rotting.
Temperature
Average warmth between 21-250C is ideal for Hare's Foot Fern. Temperatures outside this range can affect the growth negatively.
Humidity
Hare's Foot Fern thrives under high humidity. The fern is ideal for humid areas like the bathroom and other moist areas.
Increase humidity for the Fern by more frequent misting of the rhizomes to keep them moist or set the pot on a wet pebble tray. Check out these techniques on how raise humidity for houseplants.
Fertilizer (Feeding)
Feed Hare's Foot Fern with a liquid, water-soluble fertilizer every 2-3 weeks during the growing period for a lush growth.
Stop feeding during the cold season as growth is minimal at this time and feeding at this time can lead to fertilizer burn.
Pruning
Pruning Hare's Foot Fern is easy. Remove dead and damaged fronds. As the fern ages, the older fronds turn brown. Cut them off at the base to maintain the fern neat and tidy.
Repotting
Repot Hare's Foot Fern every 2-3 years at the beginning of the growing season. Use a pot that is 1 size larger than the current one.
Ensure that the pot has a drainage hole to prevent the soil from getting soggy as it can lead to rotting and eventual death of the fern.
The large Hare's Foot Fern can also be divided into several sections and potted individually to propagate new ferns.
Soil

Propagation
Hare's Foot Fern (Davallia canariensis) propagation can be done by division of the rhizomes at the beginning of the growing season.
How to propagate Hare's Foot Fern by plant division
Carefully take the Hare's Foot Fern out of its pot and divide it into several sections. Ensure each section has adequate roots.
Pot these sections into individual pots while ensuring that you do not bury the rhizomes under the soil to avoid rotting.
Place the pots in a warm, well-lit place away from direct sunlight and maintain the soil moist through out until the new Hare's Foot Ferns are well established.
