How to Grow and Care for Asparagus Ferns


Asparagus ferns are beautiful and easy-to-grow plants that can add a touch of elegance to any home or garden. They come in a variety of shapes and sizes, from small, bushy plants to large, vine-like specimens. With proper care, asparagus ferns can thrive for many years.

Types of Asparagus Ferns

There are many different types of asparagus ferns, but the most common include:

  • Asparagus densiflorus: This type of asparagus fern has fern-like foliage and grows in an arching mound up to 3 feet tall.
  • Asparagus setaceus: This type of asparagus fern is a bushy, evergreen vine that can grow up to 20 feet long.
  • Asparagus retrofractus: This type of asparagus fern is commonly called “ming asparagus fern” and rarely grows above 8 feet tall.


Asparagus ferns are relatively easy to care for, but they do have some specific needs.

Light: Asparagus ferns prefer bright, indirect light. They can also tolerate some direct sunlight, but too much sun can scorch the leaves.

Water: Asparagus ferns need regular watering, especially during the growing season. Allow the soil to dry out slightly between waterings.

Temperature & Humidity: Asparagus ferns grow best in warm, humid conditions. They can tolerate temperatures as low as 50°F, but they will not survive in freezing temperatures.

Soil: Asparagus ferns prefer well-drained, organically rich soil.

Fertilizer: Asparagus ferns do not need a lot of fertilizer. A light application of a balanced fertilizer once a month during the growing season is sufficient.

Pruning: Asparagus ferns can be pruned to maintain their shape and promote new growth. Pinch back the tips of the stems as needed.

Propagation: Asparagus ferns can be propagated by seed or division.

Seed: To propagate asparagus ferns from seed, sow the seeds in well-draining, rich soil. The seeds will germinate in 1-2 weeks.

Division: To propagate asparagus ferns by division, dig up the plant and divide the rootball into sections. Each section should have at least one stem and some roots. Replant the divisions in well-draining soil.

Repotting: Asparagus ferns should be repotted every 3-4 years. Choose a pot that is slightly larger than the root ball.

Overwintering: Asparagus ferns that are grown outdoors in cold climates should be brought indoors for the winter. Place the plants in a bright, cool location and water them sparingly.


Asparagus ferns are generally pest- and disease-free, but they can be susceptible to a few common problems, including:

  • Spider mites: Spider mites are tiny pests that can cause the leaves of asparagus ferns to turn yellow and drop off. To control spider mites, spray the plants with a strong stream of water or use a horticultural oil.
  • Aphids: Aphids are small, green insects that can suck the sap from asparagus ferns. To control aphids, spray the plants with a strong stream of water or use an insecticidal soap.
  • Root rot: Root rot is a fungal disease that can cause the roots of asparagus ferns to rot. To prevent root rot, make sure that the plants are planted in well-drained soil and that they are not overwatered.

Frequently Asked Questions
