Boston ferns need consistently moist soil but should never be waterlogged. The watering frequency depends on the environment, season, and whether the plant is indoors or outdoors.

Recommended Watering Frequency

• General guideline: Water Boston ferns about twice a week to keep the soil slightly moist but not soggy

• Indoor plants: Water every 7-10 days based on soil moisture; check by feeling the top few inches of soil and water when it starts to dry out

. During the growing season (spring and summer), watering every 2-3 days may be necessary, especially in dry indoor conditions

• Outdoor plants: May require daily watering in hot, dry weather due to faster soil drying; reduce to once a week in cooler or rainy periods

• Winter: Growth slows, so water less frequently, about once a week, while maintaining humidity by misting or using a humidifier

Watering Tips

• Water thoroughly until excess drains from the pot’s bottom to ensure deep root hydration

• Avoid letting the pot sit in standing water to prevent root rot

• Misting the fronds regularly helps maintain humidity, which Boston ferns prefer

• Use room-temperature water to avoid shocking the roots

Signs to Adjust Watering

• Underwatering: Dry, crispy, or wilting fronds indicate the plant needs more water

• Overwatering: Yellowing leaves, droopy fronds, and musty soil smell signal too much water

In summary, check the soil moisture regularly and water Boston ferns when the topsoil feels slightly dry, aiming for about twice a week or more frequently in warm, dry conditions. Adjust watering based on season and environment to keep the soil evenly moist but not soggy. Misting and humidity support the plant’s health.
