Netted chain fern Plant Care

Netted chain fern (Tectaria acrocarpa) belongs to the Tectariaceae family within the Tectaria genus. Netted chain fern is native to Southeast Asia, China.

Netted chain fern displays a low rosette, spreading growth habit, reaching up to 1.5 ft tall with a spread of approximately 2 ft. Netted chain fern produces non-flowering.

Leaf size: approximately 12 inches.

Water a young or newly planted Netted chain fern every 7–10 days, soaking the whole root zone, until it is established — usually one to two growing seasons. Established shrubs mainly need water during long dry spells. In a container, water whenever the top few centimetres of soil are dry.

Netted chain fern thrives in bright indirect to low light. Avoid placing Netted chain fern in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Tectaria acrocarpa tolerates temperatures of 60–75°F. Netted chain fern prefers humidity levels of 50–70%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Moist, well-draining soil with high organic matter content. Good drainage is essential for Netted chain fern to prevent waterlogging, which leads to root rot and fungal issues.

Feed Netted chain fern every 6 months during the growing season with a balanced, slow-release fertilizer at the rate on the label. Established shrubs in good soil often need little extra feeding, so let weak growth or pale foliage guide you.

Stop feeding by late summer so new growth can harden before winter.

The PlantoScan app can remind you when to water and when to fertilize each plant.

Choose a spot with bright indirect to low light and moist, well-draining soil with high organic matter content. Avoid low spots where water collects after rain.

Netted chain fern is suited to USDA Zone 13a.

Plant container-grown or balled-and-burlapped shrubs in spring or early autumn, setting the root flare at soil level, and water well after planting.

Netted chain fern can spread to about 2 ft (0.6 m) and reach about 2 ft (0 m) tall. Space plants about 2 ft (0.6 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Netted chain fern while it is dormant in late winter: first remove dead, damaged and crossing branches, then thin lightly for shape.

If it flowers in spring, prune right after flowering instead so you don't remove next year's buds. Never take off more than about a quarter of the shrub in one year.

Netted chain fern is frost-tender (hardy to USDA zone 13). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Netted chain fern can be propagated through spores, division of rhizomes. Similar propagation techniques also apply to tectaria estremerana plant care, which shares the same genus.

Netted chain fern is susceptible to spider mites, scale insects. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

Netted chain fern grows outdoors in USDA Zone 13a. It survives winters down to planting zone 13a. Netted chain fern is native to Southeast Asia, China. In cooler regions, grow Netted chain fern as a houseplant or bring it indoors before the first frost.
