Keep the compost moist but not soggy in the spring and summer, allowing any excess to drain away. Throughout the autumn, reduce watering and water more sparingly in the winter. In the spring and summer, feed once a month with a liquid feed.
Humidify the air by grouping plants together or misting on a regular basis, especially in the summer or when the central heating is on.
Every couple of years, in the spring, repot. Asparagus ferns are quick growers, so if your plant is getting too large or out of shape, just trim it down using sharp shears or secateurs.
Do asparagus fern like to be root bound?
Asparagus ferns don’t mind being slightly pot-bound, and can last up to two years before repotting. For the most successful repotting, divide the plant into huge clumps, and be sure to take many underground roots when dividing. To maintain the tight growth habit, divide the plants into similar-sized pots.
How do you make asparagus fern bushy?
A leggy asparagus fern can look particularly weird compared to other plants that develop a bit stretched. You might find you have a gorgeous bushier plant and then suddenly a long stem appears nearly overnight. In a matter of days, this stem can grow to be 50cm or 1 meter long, and you’re left wondering why your asparagus fern looks like that. If you enjoy the look of this then you can leave your plant but if you don’t let’s look at why it’s occurring and what you can do to stop it.
Why Is My Asparagus Fern Leggy?
A lack of light is the primary cause of a leggy asparagus fern. Because these plants are frequently labeled as low-light houseplants, many people make the mistake of placing them in a dark corner where they receive very little light. It’s because they’re trying to grow towards the light that your asparagus fern is becoming lanky and lengthy stalks are sprouting outwards. If you notice this, the best thing you can do is move your plant to a brighter location. However, avoid placing your plant in direct sunlight during the day, since this might cause it to burn, especially if you reside in a hot, sunny climate.
If you don’t have a brighter spot available then your plant might benefit from grow lights like these ones from amazon. Grow lights can work in a similar way to the sun providing your plant with the light it needs if you either don’t have room for it by a window or you live in a dark region.
Will The Seasons Affect My Plant’s Growth?
You might notice a difference in the appearance of your asparagus fern as the seasons change. Over the summer, a plant that appears bushy and healthy may begin to show signs of damage during the winter. Your asparagus fern could very easily maintain growing during the winter if your home is warm, your plant is consistently hydrated, and the soil is rich in nutrients. The light could be the only difference. Where your plant was accustomed to receiving a full day of sunlight, it may now only receive a few hours of very dim light. In other words, a plant that is good in the summer may turn lanky in the winter. If this is the case, don’t be afraid to change the location of your plant depending on the season. Changing the weather from day to day shouldn’t make a difference, but changing the seasons can.
Trimming A Leggy Asparagus Fern
You can easily clip the elongated stems away if you don’t like the look of a lanky asparagus fern. Make a cut with a sharp pair of clean scissors where you want the stem to end. You can do this with all of the elongated stems as long as they don’t make up more than half of the plant, then move your asparagus fern to a brighter position where it will grow bushier rather than leggier.
So now you know why your asparagus fern is leggy and how to fix it. However, keep in mind that it’s your plant, so if you prefer the lanky look and it’s still healthy and putting forth new growth, feel free to leave it alone and let it grow as it pleases.
In the spring, when new growth emerges, part the asparagus fern’s fronds to inspect the plant’s heart at soil level. It should be thoroughly watered. The plant’s roots are packed if the water drains toward the sides of the pot and refuses or takes an unusually long time to soak into the soil. While asparagus ferns love being a little crowded, a badly packed root ball will not permit water or oxygen to permeate the bulk to nourish the roots effectively. A bone dry root ball will eventually perish if left untreated.
How do you divide and repot asparagus fern?
When it comes to dividing your asparagus fern, the first thing to consider is when is the optimum time to do so. Early in the spring, when the plant is still dormant, is the best time to split your fern.
Dividing it now avoids any damage or unnecessary stress that might occur if you split it later in the spring or summer when the plant is actively growing.
Step 1: Watering
I water my asparagus fern thoroughly the day before I plan to divide it so that the roots are properly hydrated. When you cut the root system, this also serves to protect it from stress.
What do I mean when I say “very well watered”? I know the soil is properly wet when I poke my finger in after watering it and the top 2 inches feel drenched with water.
Step 2: Remove It From the Soil
Whether the fern is in your garden or a pot, the next step is to remove it from the soil. Flip the pot upside down while keeping your hand over the asparagus fern to remove it from the pot.
I usually gently shake the plant until it slides out, and I mean gently because I don’t want to disturb the roots or displace the soil (or a lot of it) unnecessarily.
If your asparagus fern is in your garden, gently loosen the dirt around it using a trowel. Take your plant by the roots and take it out of the ground.
Step 3: Sanitize Your Blade
Sanitizing your blade is a vital step that is frequently overlooked. I once forgot to clean my blade, and all of the ferns I had separated became infected with germs or fungus.
My plants died because I didn’t know any better, and I sincerely don’t want this to happen to you.
So dip a cotton ball in rubbing alcohol and thoroughly massage it over your knife’s serrated blade. This will ensure that no bacterial or fungal illnesses are passed to the asparagus fern.
Step 4: Gather the Fronds
Next, I gather the fronds and make sure that each area of the root ball has enough roots, stems, and leaves, whether I divide the root ball in halves or quarters.
When the portion is transferred into a new pot, it will have plenty of leaves and will have no trouble photosynthesizing and growing.
I use twist ties to tie these stems together to assist me gather the fronds and ensure that each has plenty of foliage. This method is far more convenient than simply dividing the fern.
Step 5: Divide Your Asparagus Fern
My asparagus fern is now ready to be divided. I insert the blade of my knife into the earth. I just insert it halfway between the frond parts, then cut the root connections with a back-and-forth sawing motion.
Step 6: Transplanting and Beyond
I transplant each half or quarter into a new well-draining container with well-draining soil after I have my halves or quarters. When I repot the asparagus ferns, I make sure the soil is flush with the crowns.
I also make sure to water each of my young ferns right away and keep the top inch of soil moist for the first several weeks. I start watering less once the roots have established themselves.
I also cultivate these transplants in 50 percent shade for the first few weeks before progressively reducing them to only 25 percent shade.
How do you transplant asparagus ferns?
Transplanting Asparagus Ferns from the Ground Up
- The asparagus fern should be thoroughly watered the night before the root divisions are transplanted.
Should I trim asparagus fern?
Cut any dead stems at the base of the asparagus fern to keep it in shape. Though asparagus fern responds well to trimming, be aware of the following dangers: Because its soft-looking leaves conceal sharp thorns, gloves are recommended. Allow an asparagus fern in a pot to hang from a windowsill or ledge.
Should I cut back asparagus fern?
Asparagus should ideally be chopped back in the fall, but you must wait until all of the foliage has withered back and become brown or yellow before doing so. This usually occurs after the first frost, but it can also occur without frost in areas where frost does not occur. Cut the asparagus down to about 2 inches (5 cm) above the ground once all of the foliage has died.
Can asparagus fern take full sun?
The asparagus fern is a spreading shrub native to southern South Africa’s coastal regions. Despite its common name, it is not a real fern; instead, depending on the classification system used, it belongs to the asparagus family (Asparagaceae) or the lily family (Liliaceae, which includes plants like amaryllis, daylilies, hosta, and tulips). It belongs to the Asparagus genus, which contains the edible Asparagus officinalis as well as over 300 other species. The exact classification of this species is a little hazy, with most references to Asparagus densiflorus, but some also use the names A. aethiopicus, A. sprengeri, and Protasparagus densiflorus.
This sensitive evergreen perennial with vivid green, ferny foliage is popular as a houseplant or outdoor ornamental plant. It’s used as a groundcover or in pots outside in warm regions. Up is hardy in zones 9-11, although if sheltered, the roots can easily make it to zone 7. It is grown as a seasonal annual or container plant in more temperate locations. The asparagus fern can be found in shaded, sandy areas such as coastal dunes, open rocky areas, and woodlands in its natural habitat. It is usually found along shady roadsides and invading woodlands or rainforests where it displaces native vegetation and hinders native species from reestablishing. In some parts of the United States, including as Florida, Texas, and Hawaii, it is classified an invasive weed.
The asparagus fern has long, erect or trailing branched stems with sharp, stiff spines sparsely covering the axils. The spherical stems, which can grow up to 6 feet long and have a slight indentation running the length of them, are green to brown in color and have a shallow indentation running the length of them. Leaf-like cladodes are what appear to be leaves (short, flattened stems that look and function like leaves). From the nodes along the stem, these needle-like “leaves” appear in groups of four to eight. True leaves are scales near the cladodes’ base that are barely visible. Plants feature a fibrous root structure, creeping rhizomes, and a large number of fleshy white bulbous tubers.
From spring to fall, mature plants with enough light produce little white or pinkish-white flowers in elongated clusters (racemes) along the stems. There are six tepals on each flower (3 petals and 3 sepals similar in appearance). They are little and inconspicuous, despite being fragrant, and plants planted in temperate areas rarely bloom. Plants have two sexes. Female flowers are followed by little round berries up to 1/4 inch in diameter if pollinated. The green fruits turn a glossy crimson color as they mature and contain one to three black seeds each. Many birds are drawn to the fruits, and in mild climes, they are responsible for unintentional seed dissemination. When swallowed, the berries can cause rashes and gastrointestinal discomfort, and they are hazardous to cats and dogs.
Plant asparagus fern in full sun or moderate shade; full sun plants are more compact and dense than shade plants. It thrives in moist, organic-rich soils, although it tolerates a wide range of climates and is drought tolerant once established.
The bright green, arching stems, and airy foliage of asparagus fern make it a popular ornamental. Its fine foliage has a soft or fluffy appearance and can be utilized effectively for textural contrast when combined with plants with medium or coarse-textured foliage or very large leaves. In cold climates, it can be planted in the ground alongside other annuals as a bedding plant after the final frost. In containers, this plant works well as a filler plant, especially in hanging baskets or huge urns where the delicate foliage can cascade down. When mixed with elephant ears, canna lilies, and hibiscus, it provides a tropical feel. The leaf can also be used as a filler in bouquets with cut flowers.
The asparagus fern is an excellent houseplant for inexperienced gardeners because it requires little maintenance. It thrives in direct or brilliant indirect light (the brighter the light, the faster it grows), and it can withstand periods of neglect because to its tuberous roots that store water. It thrives in a consistent moisture environment, though in the winter, the plants should be kept drier and fertilization should be avoided. If the soil is too dry or there isn’t enough light, the foliage will yellow and drop. To maintain the plant shaped, cut out any old or yellowed stems at the base and clip back the ends of stems.
Trim out old growth in the spring and begin fertilizing monthly for lush new growth. Because these plants can quickly outgrow their containers, they will need to be repotted on a regular basis. Because the roots are so powerful that they might break pots, larger, thicker containers may be preferable. Early in the spring, before new growth begins, is the optimal time to repot. Indoor plants can be moved outdoors seasonally (returning before frost), but they must be acclimated to the stronger light outside before being moved to a full-sun location. Aphids, mealybugs, spider mites, and whiteflies occasionally infest this plant, which can be found indoors or out.
Seed and division are two ways to propagate asparagus fern. At room temperature, seeds germinate in 3-4 weeks. To hasten germination, scarify the seeds and soak them in water for a day before planting. Plants can be broken down into smaller pieces, or tubers can be used to regenerate new plants. The optimal time to divide is in the spring, but these hardy plants can be propagated at practically any time of year.
‘Sprengeri’ and ‘Meyeri’ are the two most common varieties. The latter, also known as foxtail asparagus fern, has more erect stems with thicker foliage that radiates outwards from the center of the plant, mimicking a fluffy animal’s tail. This variety works well as an erect focal point in the garden or in a container with lesser plants. In warm regions, it does not generate as much seed as the species, so it does not have the same invasive potential. ‘Cwebe’ boasts copper-colored new growth and beautiful, upright, arching stems. It thrives under bright light. More compact variants include ‘Sprengeri Nanus’ and ‘Sprengeri Compacta.’
How often do you water asparagus ferns?
Garden plants should be watered once or twice a week to keep the soil from drying up completely. According to the University of Florida, asparagus ferns are generally drought tolerant, although they will develop at a slower rate if there isn’t enough moisture.
