Boston Fern

(Sword Fern)


Boston Ferns are adaptable plants that thrive in medium and bright, indirect sunlight. Prolonged exposure to bright direct sunlight may burn and scorch their leaves.


Boston Ferns enjoy weekly watering sessions, keeping their soil moist but not wet. Allow the top 2’ of soil to dry out between waterings during winter.


Your Boston Fern will appreciate being placed in a humid environment, which you can create by misting it frequently, placing it close to other plants or on a pebble tray partly filled with water. They thrive in steamy bathrooms and kitchens.


Boston Ferns prefer temperatures ranging from 18º-25ºC, but will tolerate colder or warmer spaces if kept away from cold drafts and abrupt temperature changes.


Feed with general houseplant fertiliser monthly during the growing season (spring to summer).


Boston Ferns are non-toxic and suitable for homes with small children and pets.


Browning, drying fronds: suggest your Boston Fern has been underwatered, exposed to dry air or burnt by direct sunlight.
