How to care for asparagus fern in winter? Master these key points for a safe winter
Asparagus fern likes warmth and has poor cold resistance, so it is not suitable for overwintering outdoors. Generally, it is moved indoors one or two weeks before "Frost's Descent" (when the lowest temperature drops to around 10%). After moving indoors, do not place it in the kitchen or near stoves or heating pipes. Dust, smoke and grease will clog the stomata on the branches and leaves, hindering normal respiration and growth.
In winter, watering should be controlled, and windows should be opened for ventilation when daytime temperatures are higher. To keep the air humid and prevent the branches and leaves from turning yellow, water with the same temperature as the room can be sprayed on the leaf surface every 3 to 7 days to keep it moist and clean. Fertilize once every half month. Keep the daily temperature at 15°C to 20°C and provide direct sunlight, and water when the potting soil looks dry. With the above reasonable care, asparagus fern can still remain emerald green and lush in winter.
In the depths of winter, a transparent plastic bag can be used to cover the plant together with the pot to protect it from freezing, but the lower part of the bag does not need to be tied tightly. Generally, as long as the room temperature is not lower than 3°C, asparagus fern can overwinter safely.
Key points for winter care of the indoor plant asparagus fern
Asparagus fern is a potted plant that many flower lovers like to grow. Asparagus fern is generally easy to grow and not easy to kill. I have also grown asparagus fern. I placed it on my windowsill and hardly managed it, only watering it occasionally. Now that winter has come and the weather is getting colder and colder, asparagus fern is not so easy to grow. Below I will introduce the winter care and management of asparagus fern:Morphological characteristics:
Asparagus fern, also known as cloud-pine, ci tian dong and cloud bamboo, is a perennial evergreen vine foliage plant and a famous ornamental plant. The roots of asparagus fern are slightly fleshy, the stems are soft and clustered, and the leaves are reduced to scale-like, light brown, growing at the base of the leaf-like branches; the leaf-like branches have small branchlets and are green. The scales on the main stem are mostly spine-like. The flowers are small, bisexual, white-green, and bloom in spring. The berries are spherical and turn purple-black when mature.
Growth habits:
Asparagus fern likes a warm, humid, semi-shaded environment. It is not cold-tolerant and not drought-tolerant. It likes fertile, loose, well-drained sandy loam. It likes shade, likes moisture, fears drought, and avoids excessive wetness.
Key points for winter care
1. Temperature: Asparagus fern is very afraid of cold in winter. Potted asparagus fern in winter should maintain an ambient temperature above 5°C to avoid freezing.
2. Watering: Control watering in winter. Too much watering and overly wet potting soil can easily cause root rot and yellowing and falling of leaves. When watering, note that the water temperature should be as close as possible to the surrounding temperature to reduce the stimulation of the root system from unsuitable water temperature.
3. Fertilizing: Although asparagus fern is not a heavy feeder, it cannot lack fertilizer. In winter, fertilize as little as possible. Fertilizing should be light and frequent, and never apply concentrated fertilizer, otherwise the branches and leaves can easily turn yellow.
4. Light: Asparagus fern likes a semi-shaded environment and must not be exposed to scorching sun. On sunny days, it is suitable to place the potted plant outdoors to receive sunlight, which helps it carry out photosynthesis.
5. Potting soil: Asparagus fern prefers fertile soil. If the soil is not changed and fertilizer is not added for a long time, nutrients will be in short supply and the branches and leaves will turn yellow. The potting soil for asparagus fern commonly uses a mixture of 1 part leaf mold, 2 parts garden soil and 1 part river sand as the substrate.
How to care for asparagus fern
Asparagus fern, also known as cloud-slice bamboo and mountain grass, is a perennial trailing evergreen herb in the Liliaceae family. The stems are soft, thin and jointed, growing in clusters. The leaf-like branches are slender, bright green, and densely arranged like feathers. The flowers are small, bisexual, white, and mostly open in spring and summer. The berries are spherical, initially green, and turn purple-black when mature. There are many horticultural varieties, among which dwarf asparagus fern has clustered stems and fine, short leaf-like branches; dense-leaved asparagus fern has denser leaves, a shorter plant, and grows more durably; fine-leaved asparagus fern has slender and long leaf-like branches. The branches and leaves of asparagus fern are slender, shaped like cloud slices, emerald green and light, quiet and beautiful, giving people a sense of vitality, softness and comfort. It is usually grown as a dwarfed potted plant, placed on a desk, writing table or shelf to beautify the home and study. It is a very popular indoor foliage flower, and is also an important accompanying material for fresh-cut flowers in vases, making bouquets and flower baskets.
Asparagus fern is native to South Africa. It likes warm, humid climates and semi-shaded environments, fears drought, avoids dry winds, is not cold-tolerant, and likes loose, fertile, well-drained and well-aerated sandy loam. To make asparagus fern beautiful in shape and elegant in branches and leaves, the following tasks need to be done well in care and management:
(1) Watering.
Asparagus fern is neither drought-tolerant nor waterlogging-tolerant. During the growing period, the frequency and amount of watering should be determined according to the season, growth condition and dryness or wetness of the potting soil. Usually, watering should be done to the extent that the water poured into the pot quickly seeps into the soil while the potting soil does not accumulate water. Do not water when dry, and water thoroughly when watering; do not give "half watering". Asparagus fern likes humid air, so in dry climates or hot weather seasons, in addition to keeping the potting soil moist, water should also be sprayed frequently on the branches and leaves and on the ground around the flower pot to increase air humidity. When the ambient temperature is lower in winter, watering should be controlled.
(2) Fertilizing.
Asparagus fern relatively likes fertilizer. Generally, in spring and autumn, a dilute liquid fertilizer can be applied once every half month or so. After the plant takes shape, fertilizing should be controlled to avoid excessive growth or the production of long trailing vines. When summer temperatures are high or winter temperatures are low, fertilizing is generally stopped. If no fertilizer is applied and the potting soil is not changed for a long time, nutrient supply will be insufficient, causing the plant to become weak and the branches and leaves to turn yellow. Therefore, every 1-2 years before germination in early spring, the pot should be repotted and the soil changed. The potting soil can use a culture soil mixed with 4 parts leaf mold, 4 parts garden soil, 2 parts river sand, plus a small amount of fully decomposed cake fertilizer powder.
(3) Light.
Asparagus fern likes a semi-shaded environment and must never be exposed to strong sunlight. For home care, it can be placed year-round by a window or on a balcony with bright scattered light indoors. If it can be moved to a semi-light place to receive light in spring and autumn when the sunlight is not too strong, it will be more beneficial to its growth.
(4) Shaping and pruning.
To make asparagus fern beautiful in shape and elegant in branches and leaves, shaping and pruning need to be carried out in a timely manner. One-year-old seedlings do not need pruning. Asparagus fern more than two years old will grow new climbing stems, which can be pruned at different heights so that new branches and leaves emerge from the leaf bases above, producing shaping effects at different levels. At the same time, cut off overly dense branches, dead branches and weak branches to facilitate ventilation.
(5) Winter management.
Asparagus fern likes warmth. In winter, it should be placed on a south-facing windowsill, and the room temperature should preferably be kept above 10°C. If it is placed for a long time in a place without light in winter, poor ventilation or too low room temperature can easily cause the branches and leaves to wither and turn yellow, or even fall off and die. In winter, in rooms heated by heating or a stove, spray and wash the branches and leaves with clean water close to room temperature 1-2 times a week, which not only increases the air humidity around the potted flower but also keeps the branches and leaves emerald green and fresh. In addition, if scale insects are found, they should be controlled and removed in a timely manner.
