How does sundew reproduce? Detailed explanation of propagation methods
Cutting propagation
Introduction
Although there are many varieties of sundew, the vast majority can be propagated by leaf cuttings, so when doing cutting propagation we generally use leaf cuttings; of course, using thick stems for cuttings also works.
Method of operation
When doing leaf cuttings, first cut off a whole sundew leaf, then lay the leaf flat or insert it at an angle into the soil; during this period keep the soil moist and ensure sufficient light. After about a month, the cutting will have rooted, and at this point the rooted leaf can be planted.
Seed propagation
Introduction
After flowering, sundew produces very tiny seeds, and once we have seeds we can sow them!
Method of operation
First prepare suitable soil, then scatter the collected seeds directly onto the soil, taking care to spread them evenly; there is no need to cover them with soil. After sowing, place the pot in an environment with sufficient light, relatively high humidity and a suitable temperature, and they will generally germinate in about a month! If the sundew variety is from a temperate region, low-temperature stimulation is needed to help germination.
Winter bud propagation
Introduction
Some sundew varieties from temperate regions grow some bulbils under the low-temperature stimulation of winter, and we call these buds winter buds. Winter bud propagation is a very quick propagation method.
Method of operation
Carefully pick off the bulbils with a toothpick. Since these bulbils cannot be stored for long, they must be sown immediately after being picked. After sowing, maintain a suitable environment; the sown bulbils need only a short two weeks to sprout!
How to grow sundew: sundew cultivation methods and precautions
Although sundew sounds like the name of a vegetable, in essence sundew should be an ornamental plant. As for why it is called sundew, even the clever editor does not know, but might the even cleverer you know? The methods for growing sundew and sundew care are described in detail in this article.
How to grow sundew
Sundew is a plant that likes relatively moist places; watersides or moist meadows are where it often grows. Sundew comes in rich colors, and the surface of its leaves bears glandular hairs that can secrete mucus; it produces white or red flowers.
Because these glandular hairs on the sundew leaves can secrete mucus, they look as if they are covered with dewdrops, crystal clear. This mucus can stick to insects like sticky paper, then digest and absorb them.
Sundew cultivation methods and precautions
1. Soil
Sundew has low requirements for soil; you can use soil mixed from peat soil, perlite and river sand, or you can use sphagnum moss or pure peat soil.
2. Light and temperature
Sundew likes sunlight, and sufficient light helps sundew develop vivid colors. When caring for sundew, it needs to receive a relatively long period of light every day, and it can be placed on a balcony or windowsill. If it cannot be exposed to direct light, bright scattered light can also be provided. Note that in summer, when the light is intense, shading is needed to avoid scorching. Sundew does not like environments that are too cold or too hot; the suitable temperature for growth is between 15°C-25°C. In winter it needs to be kept warm, with the minimum temperature kept above 0°C, and kept indoors if necessary; in summer, excessively high temperatures will cause it to enter dormancy.
3. Watering and fertilizing
Sundew can tolerate moisture, but it does not have high requirements for air humidity; however, in summer the humidity must not be too high, to avoid stem and leaf rot. For watering, the soil needs to be kept moist, and generally the “waist water” method can be used to supply water; the water used is best soft water. For fertilizing, apply thin fertilizer frequently; during the growing season, apply a diluted liquid fertilizer once or twice a month, paying attention to the concentration to avoid fertilizer burn.
4. Propagation methods
To propagate sundew, you can use cuttings, generally leaf cuttings, or remove the small bulbils from the plant and plant them promptly; you can also use seed propagation, which is also relatively simple.
5. Pests and diseases
During the growth of sundew, it will encounter some pests in spring and summer, such as aphids, green caterpillars and cutworms; these pests may all gnaw on sundew leaves. Once discovered, they need to be caught and killed promptly, and insecticides can be used if necessary.
Care after sowing sundew
1. Spraying water
Use a sprayer to spray water on the sundew, taking care to spray gently, otherwise the seeds may be washed away. After that, place the pot on the inner side of a windowsill that receives sunlight. If growing in a water basin, cover the top opening with plastic to maintain humidity. Pay attention to replenishing water at all times.
2. Germination and seedling emergence
Under excellent conditions, sundew can germinate in about 30 days and emerge in about 15 days.
3. Transplanting
If the sundew grows too densely after growing larger, it can be transplanted with the soil. When transplanting, be sure not to damage the roots.
4. Light
Most sundews like sun and resist scorching, and can be placed on a windowsill with sufficient light; try to let the sundew receive direct sunlight for more than four hours every day. If Northern Territory sundew receives direct sunlight all day, the color of the sundew will be very vivid. Less than four hours of direct sunlight may cause poor growth of sundew. Note that the sundew should not be kept without direct sunlight for a long time, otherwise the sundew will die. But if you are growing Drosera prolifera and Drosera binata, then you should avoid direct sunlight and place them in a cool, dimly lit place. This is because they grow in woodland, where the light is weak. So, unlike the care method for Northern Territory sundew, which needs direct sunlight.
5. Humidity
Sundew does not have excessive requirements for humidity; keeping it at 40%-90% is fine. But in the hot summer, the humidity must not remain at around 90%, otherwise the stems and leaves will rot. If stem and leaf rot occurs, ventilate promptly.
Cutting propagation of sundew
Since the vast majority of sundew varieties can be propagated by leaf cuttings, sundew cutting propagation generally uses leaf cuttings; of course, relatively thick stems can also be used for cuttings. The specific method is to cut off a whole sundew leaf, then lay the leaf flat or insert it at an angle into the soil; at this time keep the soil moist and provide sufficient light. It takes about one month for the cutting to root, and then we can plant the rooted leaf.
It is said that sundew seeds are very small, so propagating by sowing is relatively disadvantageous, so when growing sundew we usually use cuttings and transplanting more often. As for exactly how to do it, follow Zhifure, and it can help reveal the answer for you!
What is sundew like? Sundew cultivation methods
The leaves of sundew are densely covered with crystal-clear "dewdrops," dazzling and much loved by people. So, how do you grow sundew? Many people say sundew is not easy to grow, but in fact growing sundew is relatively easy, and with a little care it can grow very well. Today, we will teach everyone how to grow toothpaste plant; come and learn the cultivation methods of toothpaste plant together.
How to grow sundew
Soil: Except for tuberous sundews, other types of sundew have low requirements for soil; you can use pure sphagnum moss, or two parts sphagnum moss and peat mixed with one part perlite, and you can also add one part akadama soil, bark, vermiculite and other substrates. Tuberous sundews can use granular soil; for example, if using the tray immersion method, you can mix 1 part peat with 1 part perlite or river sand.
Light: Sundew likes sufficient sunlight and tolerates scorching, and is suitable for placement on a balcony or window with good light. If it can be provided with all-day direct light, it will show very vivid colors, and the mucus will also become more viscous. If there is no good light environment, bright scattered light should also be provided all day.
Humidity: Sundew does not have high requirements for humidity, which needs to be controlled at 40%-90%. Higher humidity can make the "dewdrops" on the glandular hairs larger and more ornamental. During the plum rain season, when the air humidity is relatively high, ventilation should be strengthened, otherwise it may cause stem and leaf rot in sundew.
Watering: Sundew is usually relatively moisture-tolerant, and the tray immersion method can be used to supply water, that is, place the pot in a container such as a water tray or glass tank with water, allowing the water to seep through the entire pot on its own. Just keep about 1 cm of water in the tray, and the substrate can be kept moist. Sundew has relatively high requirements for water quality; when watering, use soft water with low content of minerals such as calcium and magnesium.
Fertilizing: During the growing season of sundew, a general compound fertilizer diluted five thousand times should be sprayed on the leaves, 1-2 times a month. When fertilizing, it is better to apply thin fertilizer frequently; never use too high a concentration, to avoid the serious consequences of fertilizer injury or even fertilizer death. Do not fertilize casually without experience. It is not recommended to provide nutrients by feeding food, to avoid affecting the ornamental value.
Pests and diseases: Every spring and summer, the new buds of sundew may be attacked by aphids, causing deformed or withered leaf growth. Pests such as green caterpillars and cutworms may all gnaw on sundew leaves. When signs of gnawing are found on the leaves, they should be caught and killed promptly, or a broad-spectrum (general-purpose) insecticide can be used to kill them; when using it, just spray the leaves wet, and never spray heavily.
Sundew varieties
Drosera natalensis
Drosera natalensis originates from remote mountain areas of South Africa, where the climate is stable year-round and summer does not exceed 33 degrees. In cultivation, D. natalensis and Drosera capensis are the first choices of flower enthusiasts for upright sundews, but D. natalensis is more delicate and also more afraid of heat, and is suited to cultivation in an airy medium.
Drosera capensis
This is the most famous sundew, and its tall and mighty image is deeply rooted in people's hearts; its leaves curl in a very exaggerated way. In its place of origin, South Africa, it is a lowland sundew and has multiple forms. In cultivation it is somewhat afraid of heat; grow it in summer with ventilation and shading, and it will be very beautiful in autumn.
Drosera filiformis
Drosera filiformis can be roughly divided into red thread-leaved, green thread-leaved, and common thread-leaved; among them, the red thread-leaved is the most famous variety. In cultivation it is slightly afraid of heat; in summer just avoid the midday sun with shading. It can be considered an entry-level variety of temperate sundew and is worth collecting.
Other sundew varieties include Drosera beleziana, Drosera binata, Drosera admirabilis, Drosera hartmeyerorum, Drosera aliciae, Drosera pulchella, Drosera regia, Drosera burmannii, etc.
