Growing Asparagus densiflorus (Asparagus Fern)

Athough not a true Fern, Asparagus Fern (Asparagus densiflorus) is valuable for its bright green, graceful arching stems and needle-like foliage. It adds fullness and texture to annual container collections and is popular in hanging baskets indoors and out.

Light/Watering: Grow in partial shade and water when the top inch of soil is dry.

Fertilizer/Soil and pH: Use a soil-based potting mix and apply a balanced liquid fertilizer monthly throughout the growing season (April to September).

Pests/Diseases: If spider mites or aphids find your plant, treat with an insecticidal soap spray, such as Safer's.

Companions: Combine with flowering annuals such as Petunias, Lantana, and Verbena to provide a soft texture to a container collection.

End-of-Season Care: In all but the mildest winter climates (plants are hardy to Zone 9 [20°F]), bring plants indoors before frost and overwinter in a sunny window in a cool room. Water sparingly in winter. Set back outdoors after the danger of frost has passed in spring.
