With its delicate, lacy fronds, Asparagus setaceus pyramidalis, commonly called lace fern or tree fern, is a stunning plant that adds airy beauty to any indoor or outdoor space. This unique plant is not actually a true fern but gets its common name from its delicate, fern-like foliage. Here is a complete guide to growing and caring for this eye-catching plant.

Overview of Asparagus Setaceus Pyramidalis

• Native to South Africa, grows as an evergreen perennial in warm climates, a houseplant or annual in colder zones.

• Features finely-cut needle-like leaves clustered on upright stems forming a pyramid shape. Grows up to 3-4 feet tall.

• Thrives in bright, indirect light. Tolerates some direct sun in cooler climates but appreciates afternoon shade in hot areas.

• Does best in average room temperatures, 60-75°F. Protect from frost.

• Prefers a humid environment. Mist leaves frequently or use a pebble tray.

• Water when the top inch of soil becomes dry. Droopy fronds indicate under watering.

• Can be grown outdoors in zones 9-11, where it grows quickly to tree-like heights up to 10 feet tall.

With proper care, this elegant plant can grow for many years, lending its graceful charm indoors and out.

How to Grow Asparagus Setaceus Pyramidalis

Lace fern can be easily propagated by seed or plant division:

• Start new plants from seed indoors in late winter. Germination takes 14-21 days at 70°F.

• Divide congested plants in early spring, being sure each division has some roots. Replant immediately.

• Plant in a well-draining potting mix, water thoroughly after planting and mulch to retain moisture.

• Outdoor plants need rich, loose soil and regular watering until established. Space plants 2-3 feet apart.

• Repot container plants every 2 years in early spring. Move to a container one size larger.

Optimal Growing Conditions

• Light: Bright, filtered light indoors. Outdoors, plant in part sun avoiding hot afternoon sun.

• Temperature: Average room temperatures from 60-75°F. Avoid drafts.

• Soil: Rich, humus-heavy potting mix that drains well. Soil pH 6.0-7.0.

• Water: Water when the top inch of soil is dry. Water deeply and allow soil to fully drain.

• Humidity: Prefers 40-60% humidity. Mist leaves often or use a pebble tray.

• Fertilizer: Use a balanced liquid fertilizer every 2-4 weeks in spring through fall.

Caring for Asparagus Setaceus Pyramidalis

A few simple care tips keep lace fern looking its best:

• Water thoroughly when the soil surface becomes slightly dry to a depth of 1-2 inches.

• Mist leaves every few days to supplement humidity. Keep out of hot, dry air.

• Wipe leaves periodically with a damp cloth to remove dust and debris.

• Remove faded fronds at the base to encourage new growth.

• Rotate the plant periodically to encourage even growth on all sides.

• Protect outdoor plants from frost and freezing temperatures.

• Repot container plants every 2 years in fresh potting mix. Spring is ideal.

Potential Problems and Solutions

• Brown leaf tips indicate dry air. Improve humidity through misting.

• Yellowing leaves often mean overwatering. Allow soil to dry out between waterings.

• Dropping leaflets result from under watering. Increase watering frequency.

• Leggy growth means insufficient light. Move plant to a brighter location.

• Spider mites can be a pest issue. Wipe leaves with a damp cloth regularly to prevent buildup.

• Snails and slugs may chew leaves. Remove by handpicking.

Promptly addressing any problems will keep plants looking healthy and vigorous.
