Asparagus Fern Plant Care Guide:
Tips and Tricks for Healthy Growth

Asparagus ferns are elegant, low-maintenance plants that can add a touch of green to any space. They are not actually ferns, but rather members of the lily family. These plants are native to South Africa and are known for their delicate, feathery foliage and small white flowers that bloom in the summer.

If you’re looking to add an asparagus fern to your collection, or you already have one and want to ensure its healthy growth, this care guide will provide you with all the information you need.

Light Requirements

Asparagus ferns prefer bright, indirect light. They can also tolerate some shade. However, direct sunlight can scorch their leaves, so it’s best to keep them away from windows that get a lot of sun. If you notice that your fern’s leaves are turning yellow or brown, it may be getting too much direct sunlight.

Watering

Asparagus ferns like consistently moist soil but not overly saturated soil. Water your plant once a week, or when the top inch of soil feels dry to the touch. Be sure not to overwater it as this can lead to root rot.

Temperature

These plants thrive in temperatures between 60-75°F (15-24°C). They can tolerate slightly cooler temperatures but should not be exposed to frost or freezing temperatures.

Humidity

Asparagus ferns prefer high humidity levels. You can increase the humidity around your plant by placing a tray of water nearby or misting it with water every other day.

Soil

Asparagus ferns prefer well-draining soil that is rich in organic matter. A good potting mix for these plants should contain peat moss, perlite, and vermiculite.

Fertilizer

Fertilize your asparagus fern once a month during the growing season (spring and summer) with a balanced liquid fertilizer. Be careful not to over-fertilize as this can damage the plant’s roots.

Pruning

Prune your asparagus fern regularly to remove any dead or discolored foliage. This will help to promote healthy growth and prevent disease.

Propagation

Asparagus ferns can be propagated by division or by taking stem cuttings. To propagate by division, carefully separate the plant’s roots into smaller sections and repot each section in its own container. To propagate by stem cuttings, take a 3-4 inch cutting from the tip of a stem and place it in a pot filled with moist potting mix. Keep the cutting moist and warm until it develops roots.

Common Problems

Spider Mites

Spider mites are tiny pests that can infest your asparagus fern and cause damage. Look for yellowing leaves with tiny webs on the undersides. To treat spider mites, wash your plant with insecticidal soap or neem oil.

Mealybugs

Mealybugs are small, white insects that feed on plant sap and excrete a sticky substance called honeydew. They can cause stunted growth and leaf drop in asparagus ferns. To treat mealybugs, wipe them off with a cotton swab dipped in rubbing alcohol.

Brown Tips

Brown tips on your asparagus fern’s leaves can be caused by either underwatering or overwatering. Make sure you are watering your plant consistently and not letting it dry out completely between waterings.
