The tree fern thrives best in warm environments that mimic its original tropical habitat. When choosing where to plant it, keep thesepreferences in mind:
-
Hardy in zones 9-11 – Due to its preference for heat, it can be grown as a perennial outdoor plant only in zones 9 through 11. Elsewhere, it is cultivated as a seasonal annual or houseplant.

Bright indirect light – The plant thrives in bright filtered sunlight. Direct hot sun will scorch its delicate foliage. Indoors, place near an east, west or south window.

Moderate temperatures – Daytime temperatures between 65-85°F are ideal. The plant cannot tolerate frost or freezing weather.

High humidity – Mist the plant daily or use a pebble tray to provide the humidity levels above 50% that it prefers. Dry air will cause leaf browning.

Well-draining soil – Plant in a loose, porous potting mix. Soil that is heavy, clay-like or retains too much moisture will cause root rot.

Planting and Care
Caring for the asparagus setaceus pyramidalis is easy with just a few simple practices:
-
Water regularly – Water thoroughly whenever the top inch of soil becomes dry. Allow it to fully drain to prevent soggy soil.
-
Fertilize in spring and summer – Use a balanced liquid or slow-release fertilizer to encourage growth during the active seasons.
-
Prune lightly – Remove dead or damaged fronds occasionally to encourage new growth. Never prune more than 1/3 of the plant at once.
-
Repot annually – In spring, move the fern to a container one size larger to provide room for growth.
-
Bring indoors before frost – Outdoor plants should be moved into a brightly lit indoor location before temperatures drop below 50°F.

Propagation and Growth Rate
This tropical fern propagates in a couple ways:
-
By seed – Soak seeds overnight, then plant 1/4” deep in seed starting mix. Keep warm (70-75°F) until germination.
-
By division – In early spring, carefully divide root clumps from more mature plants, ensuring each has some root growth. Replant immediately in potting soil. Keep warm and well-watered until established.
-
From cuttings – Take 5-6” stem cuttings in spring. Dip in rooting hormone and plant in potting mix. Enclose in a plastic bag until rooted, then gradually expose to air.
