Wild Boston Fern
Boston, the most common and favourite fern, has several varieties and is relatively easy to grow. It is a large variety having upright, graceful green foliage with long, elegantly curved fronds divided into small leaflets (pinnae). The foliage arising from underground stems called rhizomes can grow up to 6 feet tall. The 3-5 feet long fronds are variously cut and the individual pinnae are about 3" and narrow. The round sori (clusters of spore-bearing organs) occur in two rows near the margins on the underside of the pinnae.
Boston fern is usually grown in moist, shady areas. It looks beautiful in hanging pots or on pedestals and can also be used as an indoor plant. Like the other ferns, it likes a moist but not soggy soil, rich in organic matter and high humidity. It requires only indirect lighting and should be watered regularly. Propagation can be done from spores or by division. During their growing season, the fern requires regular fertilization. When roots fill the pot, the fern should be repotted.
Only moderate care is needed for its healthy growth. Although they are considered generally pest free, aphids, mealy bugs and mites are the most common insect problems. A good spray with water will usually dislodge any insects on the plant. Root rot may be a problem and adequate drainage should be provided to avoid the condition.
