The frequency of watering your fern will depend on various factors, including the specific fern variety, the environmental conditions, and the type of growing medium used. As a general guideline, most ferns prefer consistently moist soil. It’s essential to avoid overwatering, which can lead to root rot, as well as underwatering, which can cause the fern to dry out. To determine when to water, check the moisture level of the soil by touching it. If it feels dry to the touch, it’s time to water. However, always adapt your watering routine based on the specific needs of your fern.
