Asparagus densiflorous (also called Springeri Fern) is a perennial (hardy in Zones 9b-11) used in landscape, combination planters and standalone containers. Though not a true fern (it's really a member of the lily family), its upright, sprawling habit and finely textured, evergreen foliage make it an interesting plant to add diversity to your garden center selections. A native to southern Africa, Springeri Fern handles drought very well. These fast-growing plants can spread 3-4 feet and reach heights of 1-2 feet. As the branches get longer, they will cascade due to their own weight and can be trained to flow over a wall or container.
For best results with Asparagus Fern, we recommend using a constant feed program of 150-200 ppm N
.Springeri are drought resistant, so grow them a little on the dry side in a well-drained soil. Maintain a pH between 5.8 - 6.2.
Springeri do not require pinching
. Trimming or clipping an overgrown pot may be useful in maintaining its shape.
Space pots as needed to allow air flow and penetration of light

for Asparagus Fern. Clipping may be useful in maintaining the proper height on your final product.
, and occasionally whiteflies
are the biggest pest problems for Springeri.
Asparagus (Sprengeri) Fern is not prone to many diseases, but don't oversaturate the soil
. If the plant sits in moist soil for an extended amount of time, you could end up with root rot or botrytis
. Botrytis grey rot is usually associated with wet or humid conditions. You can prevent botrytis by allowing the plant to dry out between waterings, allowing for good airflow in your greenhouse, and spacing to allow the sun to penetrate to the soil level. The most common chemicals used to treat botrytis and root rot are Medallion and Banrot. Use them as a drench according to each label's instructions.
Planting Asparagus (Sprengeri) Fern Liners
- We recommend planting 4-5 starter plants per 10 inch basket. Use a well-drained soil in your baskets and plant your starter plants deep, allowing the ellepot to be completely covered by the soil. If you are planting 4" pots, 3 plant per pot should be sufficient. Plant them directly in the middle of your pot in a triangle formation.
- Pinching is not recommended, but clipping may be useful in maintaining the proper height on your finished product.
Cuttings vary in size between different plant families. These rooted starter plants will arrive ready to be transplanted in to your final container. If they are to be used in a landscape application, you will need to establish them in a 4 inch pot or an 1801 before planting outside.
