Ornamental perennial ferns with long, delicate leaves that resemble feathery clusters make up asparagus plumosa. The fern-like foliage of asparagus ferns gives it its name. The Asparagaceae family contains asparagus ferns, which are not classified as true ferns. Lace fern, climbing asparagus, asparagus grass, and ferny asparagus are all terms used to describe the Asparagus plumosa fern.
Asparagus setaceus, Asparagus plumosus, and Protasparagus setaceus are the botanical names for asparagus plumosa ferns. But, the common asparagus fern (or plumosa fern) is referred to by all of these botanical names. Because of their resemblance to ferns, asparagus plumosa ferns are called ferns. Evergreen asparagus ferns have feathery foliage that looks like that of a real fern. Asparagus ferns, unlike genuine ferns in the Polypodiopsida class, don’t produce spores. Instead, they create seeds.
A cladode is a kind of asparagus plumosa fern leaf. Flat stems that resemble leaves are the leaf-like plant components. Asparagus ferns can’t photosynthesize without cladodes.
The flattened stems of asparagus plumosa ferns, known as cladodes, are leaf-like in appearance. Asparagus ferns produce tiny red berries with seeds after blooming. In warm regions, asparagus plumosa ferns may become invasive. Asparagus ferns flourish in USDA zones 9 to 11 and may quickly overrun gardens. To keep asparagus ferns from becoming invasive, plant them in pots outdoors. This is the best recommendation. Easy-to-care-for houseplants include asparagus plumosa ferns.
How to Care for Asparagus Plumosa Fern – Overview
In rich, loose, well-draining soil, grow asparagus plumosa ferns. To prevent the soil from drying out, water plumosa ferns are frequently enough. By daily misting their fern-like leaves, you can increase humidity. Asparagus ferns thrive in dappled shade and need to be shielded from the sun. During the growing season, fertilize the potted fern monthly.
Types of Asparagus Fern
The family Asparagaceae includes 300 species of plants. According to some sources, there are seven different kinds of fern that have been declared invasive garden weeds. One of the most frequent plants in the genus is Asparagus setaceus (also known as Asparagus plumosus or Protasparagus setaceus). More asparagus fern species may be found here:
Asparagus Foxtail Fern (Asparagus densiflorus ‘Myersi’)
Bushy stems that resemble a fox’s tail grow on asparagus foxtail fern. The stems are cone-shaped and have a light green color. With a spread of 4 ft. (1.2 m), foxtail ferns grow up to 2 feet (0.6 meters) tall.
Sprenger Asparagus or Sprengeri Fern (Asparagus densiflorus ‘Sprengeri’)
Sprenger ferns have arching stems and delicate, airy leaves. This decorative fern-like plant is ideal for hanging baskets because of its delicate, needle-like leaves and cascading branches. Sprengeri asparagus ferns can grow to be up to 2 feet (0.6 meters) tall.
Ming Fern (Asparagus retrofractus)
Long thin stems and needle-like leaves grouped in clusters characterize Ming ferns. As it grows, the shrubby plant develops into a timber. The plant is also known as the zig-zag fern or pom-pom asparagus fern because of its rapid growth.
Compact Sprenger Asparagus Fern (Asparagus densiflorus’ Sprengeri Compacta’)
Long feathery stems with shinny green needle-like leaves characterize the compact sprenger asparagus fern. This plant produces tiny clusters of white blooms with red berries, similar to other species of asparagus ferns.
Asparagus Plumosa Fern Care
Easy-to-care-for asparagus plumosa ferns are a good houseplant. Grow your plumosa fern in mostly shaded, moist, well-drained soil to look after it. Regularly watering and misting plumosa ferns is important to keep humidity levels high. In typical room temperatures, asparagus plumosa ferns thrive.
They need protection from the cold in the outdoors. The care instructions for asparagus plumosa ferns are provided in detail below.
Asparagus Plumosa Fern Light Requirements
In dappled shade, grow asparagus plumosa ferns. Since the plants will adapt to the light, you may grow plumosa ferns in a bright room. The delicate, airy foliage may be scorched by direct sunlight. In addition, the soil can be dried out too quickly by direct sunlight.
A shaded corner of a bright room is the best place for an asparagus plumosa fern. A north-facing window is usually ideal for plumosa ferns. When the plants get enough morning sunlight but no scorching midday heat, east-facing windows are also beneficial. Always shield the fern-like plant from direct sunlight to ensure proper development and prevention of yellowing leaves.
The Best Soil for Asparagus Plumosa Ferns
The ferns of asparagus plumosa need moist, oxygenated soil. For houseplants, add enough organic material and perlite to potting soil. Easy-grow asparagus ferns thrive in a rich, fertile potting mix, even in any soil type. Make sure the soil isn’t soggy, whatever kind you choose.
For growing asparagus ferns, perlite is an excellent addition to a potting mix. Excess water can freely drain due to the inorganic matter. Organic matter, such as peat moss, helps to retain the correct amount of moisture. To prevent asparagus fern roots from standing in overly-moisture soil, make sure your pot has drainage holes.

How to Water Asparagus Plumosa Ferns
The soil of asparagus plumosa ferns isn’t usually completely dry, allowing for frequent watering. When the top 1″ (2.5 cm) of soil is dry, water the plumosa ferns. Water the fern-like plant thoroughly until the water runs out at the bottom. Asparagus ferns may need to be watered every week.
Allow the soil to partially dry before watering any asparagus fern. The potting mix can never be too wet with this watering tip. Additionally, this method ensures that the soil around the taproots is moist but never becomes soggy or mushy, which is essential for asparagus ferns.
It’s preferable to thoroughly wet the soil when it comes to watering. Next, let the extra water to flow away naturally. As long as you allow the top layer of soil to dry out, deep hydration keeps the roots healthy.
Best Temperature for Growing Asparagus Ferns
Asparagus plumosa ferns may be grown outdoors in temperatures ranging from 65°F to 70°F (18°C to 21°C). Asparagus ferns thrive in warm conditions. It’s important to keep asparagus ferns in your home protected from temperature variations. Thus, keep the fern-like plants away from heat and drafts by keeping them in the shade.
In USDA zones 9 – 11, asparagus plumosa ferns may be grown outdoors. Dappled shade should have average temperatures of around 70°F (21°C). At temperatures below 55°F (13°C), asparagus ferns can’t develop. The delicate evergreen plant is commonly killed by frost.
Asparagus ferns may be grown in containers if you live in colder regions. On patios, deck areas, or balconies, these spreading bushy potted plants are a great way to add foliage. Keep your potted asparagus fern safe from harsh weather by putting it in a shaded area.
Humidity for Asparagus Plumosa Ferns
When growing indoors, asparagus plumosa ferns need a lot of humidity. Spray a fine mist over the bushy foliage of asparagus ferns every day to humidify them. The majority of households do not have enough humidity for their plants. The asparagus plant is prevented from drying out due to the additional moisture. To keep asparagus plumosa ferns growing indoors, follow these tips:
Humidifying water tray—To keep asparagus ferns moist, use a pebble tray. In a large tray, layer decorative pebbles. Fill halfway up the stones with water. Make sure the asparagus fern pot isn’t sitting in water before placing it on the pebbles.
Room humidifier—For moisture-loving houseplants like plumosa ferns, use a humidifier to increase humidity. For best results, keep the humidifier at a humidity level of at least 50%.
Grow plants together—The humidity can be increased by growing your houseplants close to each other. Nonetheless, to maintain adequate air moisture levels, asparagus ferns may need regular misting.
How to Fertilize Asparagus Plumosa Fern
During the growing season, asparagus plumosa ferns benefit from fertilizer. Apply half-strength liquid houseplant fertilizer from spring through early fall. Monthly fertilizing is necessary for robust, thriving development of plumosa ferns. Instead, you may apply a three-times-a-year slow-release granular fertilizer in the spring, summer, and autumn.
Mineral salts in the potting soil must be avoided if possible. Fill the asparagus fern potting mix with water every two or three months. Pour water into the ground for two minutes, then allow all the excess liquid to escape. fertilizer root burn is prevented by this plant care method. You may continue fertilizing the asparagus fern normally after flushing the potting soil.
Trimming (Pruning) Asparagus Plumosa Ferns
In order to limit the plant’s expansion, prune away dead or yellow asparagus plumosa fern leaves. Annual pruning may encourage proper development of asparagus ferns, despite the fact that they are fast-growing plants. You may also eliminate yellow or brown cladodes by trimming the plant. It’s critical to wear protective gloves while pruning an asparagus fern. Thorns might develop beneath the thick foliage of older plants.
An asparagus fern can be pruned in several ways:
- Use sharp, sterilized pruning shears to cut back the old asparagus plumosa stems at the base.
- To encourage bushy, thick development of the asparagus fern, pinch off stem tips.
- At the soil level, prune yellow or brown asparagus fern stems.
- To help keep the plant’s compact shape, cut off long stems.
Repotting Asparagus Ferns
Every spring, asparagus plumosa ferns should be repotted. When the roots of an asparagus fern protrude from the drainage holes, it’s time to repot it. The plant has become rootbound, which may also cause water to flow more slowly. It’s also possible to check the roots of repotting houseplants.
Here is how to repot an asparagus plumosa fern:
- Remove the root ball of the asparagus fern from its jar carefully.
- Inspect the roots of your plumosa fern for signs of wear after shaking off the excess soil.
- Any brown or mushy roots should be trimmed.
- Select a pot that’s one size bigger than the existing one.
- A light potting soil should be used to half fill the pot.
- Add more soil to the pot if you’re using asparagus fern.
You can use the period between repotting asparagus plumosa ferns to propagate their roots.
How to Propagate Asparagus Plumosa Ferns
Divide the bulb-like roots of an asparagus plumosa fern or plant its seeds to grow more. Ensure that each tuber root portion has a lot of shoots when propagating the plant with root division. Plant in new pots or partially shaded areas of your garden after separating the asparagus fern into two or more pieces.
By root division, you can propagate the asparagus plumosa fern:
- Shake off the loose soil from the asparagus plumosa plant before removing it from its pot.
- Try to split the tubers into two or more pieces.
- Alternatively, use a clean knife to slice through the tuber root on the plant’s side.
- Water thoroughly before planting your plumosa fern’s separated tubers in a suitable pot.
Asparagus fern seeds may be propagated in the following manner:
- The berries of your asparagus plumosa fern can be used to collect seeds.
- For a few days, soak the asparagus plumosa seeds in water.
- Remove the floating bad seeds from the top.
- Cover the asparagus plumosa seeds with a thin layer of soil and plant them in the ground.
- Before it gets too hot and dry, water the seedling thoroughly.
- Within two or three weeks, seedlings should emerge.
Are Asparagus Plumosa Ferns Toxic?
Cats and dogs should not eat asparagus ferns. Toxins may be found in plumosa ferns, emerald feather ferns, sprengeri ferns, and racemose asparagus ferns. Vomiting, dermatitis, abdominal discomfort, or diarrhea are all indications that your cat, dog, or companion has consumed parts of the asparagus fern.
Pests that Can Affect Asparagus Plumosa Fern Growth
Asparagus ferns are seldom plagued by pests. Houseplant pests, such as scale insects or mealybugs, are common problems on asparagus ferns. When feasible, pests on plumosa ferns should be treated right away. Scale and mealybugs affect the plant’s growth by sucking nutrients out of it.
A neem oil solution is effective for pest management on asparagus plumosa ferns. Add 1.5 tsp of powder to the mixture. 33 fl oz of vegetable neem oil and 1 tsp of mild dish soap Warm water (1 liter) Shake vigorously before filling a spray bottle. To get rid of scale or mealybugs, spray your infested asparagus ferns once a week.
Diseases that Can Affect Asparagus Plumosa Growth
The most common fungus that affects asparagus plumosa growth is fungal root rot. Never water your ferns too much to avoid root disease. This can be done by watering when the soil is partially dry and ensuring that water drains freely from the pot. Asparagus ferns should be avoided in dark settings.
Yellowing leaves, wilting development, and red staining on the stalk bases are all symptoms of asparagus fern root rot. Remove the plumosa fern from its container if you notice signs of illness. Look for brown lesion tubers in the roots, and trim off the afflicted sections with sterilized equipment.
FAQs About Asparagus Plumosa Fern Care
For asparagus ferns to grow healthily, they require little attention. The care of these dogs, on the other hand, may be impacted by a few factors.
Why is my asparagus fern yellowing?
Too much sunlight is the primary cause of yellow asparagus fern foliage. Too little light or too much water can also cause yellow leaves in asparagus plumosa. Plants of Asparagus plumosa need some sunlight, but they also need protection from direct sun. Move the asparagus fern to a more shady spot if you notice yellowing leaves.
Too little light might also be indicated by yellow asparagus plumosa leaves. Asparagus ferns require some light, warmth, and humid conditions, unlike true ferns that thrive in dark, damp conditions. Too much water might cause asparagus fern leaves to discolour. The roots are drowned in too much moisture, preventing them from getting enough oxygen. As a result, when the soil dried somewhat, only water an asparagus fern.
Do asparagus ferns have bulbs?
Tubers are the underground bulbs of asparagus ferns. Moisture retention is great with the fleshy roots. When you want to grow the plant, you divide the asparagus fern bulbs.
