Boston Fern Care Guide

Your Frondy Friend, the Boston Fern

One of the most popular varieties of fern is the Boston fern. This wide-spreading plant with beautiful arching fronds (divided leaves) makes a wonderful addition to the home. The fronds or leaves of this fern can grow as long as 2-3 feet and 4-6 inches in width.

It’s good for you!

Fun fact:

Ferns are an ancient group of plants. From the fossil record, scientists consider that land plants emerged from the water around 475 million years ago. By about 400 million years ago, vascular plants had separated from non-vascular plants, and soon after this, ferns separated off. By about 350 million years ago, some of the major families of ferns are seen in the fossil record. This makes ferns older than most land animals – some invertebrate animals were on land by this time – and far older than dinosaurs! (sciencelearn.org)

LIGHT

It prefers bright, indirect light and will be happy sitting close to a window that gets lots of sunlight.

WATER

It’s important to never allow ferns to become dry at the roots.

Water once or twice a week but make sure that the top 1″ – 2″ of the soil is dry before watering. On extra hotter days, water plants as often as necessary to keep the potting mix thoroughly moist as it may dry out quicker.

If leaves are turning pale, it needs water. If they’re turning crispy and brown, it’s being overwatered.
