This native plant of East Asia has become a common sight in the darker spots of many gardens. It is also often grown as an indoor plant. With people enjoying its decorative foliage and relatively low care needs.<\/p>\n\n\n\n

The Japanese Holly Fern typically reaches a height of 1.5 to 2 feet (45 to 60 cm). And it has a similar spread. <\/p>\n\n\n\n

Plants carry distinctive fronds that can reach about 1 to 2.5 feet (30 to 75 cm) in length. These fronds have a broad and arching nature, with their leaflets being a little reminiscent of holly leaves. <\/p>\n\n\n\n

As a fern, this plant does not flower, but carries striking fronds. These help to provide year-round interest indoors and out. <\/p>\n\n\n\n

As it can tolerate shade, it does particularly well when used as a woodland garden plant. It also looks great in borders, rockeries, and containers (where it can be grown outdoors or as a houseplant). <\/p>\n\n\n\n

Cyrtomium falcatum<\/em> is an adaptable plant with an attractive appearance that thrives in USDA Hardiness Zones 6 to 10, this is equivalent to about RHS H4 to H5, thus making it hardy to fairly cold winters.<\/p>\n\n\n\n

How to Grow Cyrtomium falcatum in the Garden<\/h2>\n\n\n\n

This fern does best in full to partially shaded locations, which makes it perfect for the darker areas of your garden. <\/p>\n\n\n\n

It will require a well-drained, moist soil rich in organic matter.<\/p>\n\n\n\n

Once Japanese Holly Fern is established, it will require only the minimal of care. Regular watering will be required as it loves a moist soil, but avoid waterlogging the soil as this may result in root rot. <\/p>\n\n\n\n

Feed it monthly with a monthly balanced, liquid fertilizer to encourage growth and maintain soil nutrition.<\/p>\n\n\n\n

To propagate Cyrtomium falcatum<\/em>, spores can be collected in late summer or early fall. Inoculate the spores on the surface of a moist compost in a covered container. <\/p>\n\n\n\n

Maintain a temperature of 60 to 70\u00b0F (15 to 20\u00b0C) until development of the prothallus (heart-shaped fern gametophyte stage) occurs.<\/p>\n\n\n\n

Though less fun, this fern is more commonly propagated by dividing mature plants in the spring. When repotting make sure that each division has a healthy amount of both of roots and fronds.<\/p>\n\n\n\n

Although this fern is hardy it can be susceptible to certain pests, such as scale insects and mealybugs. Be on the look out for these and remove them before they have a chance to do any damage to your fern. When grown in pots, over-watering may lead to the roots becoming rotted.<\/p>\n\n\n\n

Growing Japanese Holly Fern as a houseplant<\/h2>\n\n\n\n

When grown indoors as a houseplant, Cyrtomium falcatum will do best when placed in medium to low light conditions. Keep it away from direct sunlight. <\/p>\n\n\n\n

Provide it with some water when the top inch (2.5 cm) of soil has become slightly dry. It is important to keep the soil moist, but do not let it get waterlogged, ensuring it remains moist, but not waterlogged. <\/p>\n\n\n\n

Misting the fern or using a pebble tray with water can help to maintain humidity if you are growing in a dry room. <\/p>\n\n\n\n

Shield the fern from any cold drafts, and try to maintain a temperature of 60\u00b0F to 75\u00b0F (15.5\u00b0C to 24\u00b0C).<\/p>\n\n\n\n
