Nepenthes propagation methods
This article summary: Relevant knowledge about the propagation of Nepenthes, Nepenthes propagation methods, next, the editor will introduce to everyone.
Nepenthes can be propagated by layering, cutting, and sowing. The first two methods are suitable for home cultivation, while the latter method is mostly used by commercial producers and scientific researchers.
Layering propagation should be carried out in late spring and early summer each year, selecting strong branches from healthy plants, cutting 2-3 nodes or 1 leaf with a section of stem as cuttings, cutting the leaves in half, cutting the base at a 45-degree angle, wrapping the base of the cuttings with sphagnum moss, placing them in a pot with sphagnum moss and small pebbles at the bottom, and covering the pot and cuttings with a large plastic bag to maintain 100% humidity and a high temperature of 30°C; or applying rooting powder or indole butyric acid root stimulant to the cut surface, inserting it into moist sphagnum moss or coarse sand, keeping the environment wet and well-lit with high temperature and humidity; it is also possible to use a single node with an axillary bud for layering, cutting off a node with a bud and leaf, applying rooting powder or indole butyric acid root stimulant to the cut surface, and inserting it into moist sphagnum moss, exposing the axillary bud. It usually takes 3-4 weeks to root, and the cuttings can be transplanted when the new buds grow to 2.5-4 cm and develop 1-2 leaves.
Layering propagation is divided into ground layering and high layering. Ground layering involves selecting strong and flexible branches during the growing season, cutting the stem section with a sharp knife to form a "V" shape, wrapping it with moist moss or burying it in moist moss or soil, pressing and watering thoroughly, and sometimes using bricks or stones to hold the stem section down to prevent it from lifting from the soil. After about one month, new roots will grow from the cut, and when the new buds grow to about 4 cm, they can be cut from the mother plant and planted in a pot. For air layering, mature and strong branches should be selected, making a stem cut or a "V" shape cut on the stem section, applying rooting powder, wrapping with moist moss, and then covering with plastic film and securing the top and bottom openings. After 2-4 months, when new roots have grown, they can be cut and planted in a pot after removing the outer wrapping film.
In comparison, the播种繁殖 (sowing propagation) of Nepenthes is more troublesome, requiring artificial pollination to obtain seeds, and the seeds must be sown immediately after collection. Sowing should use seedling trays and be placed in a greenhouse or small arch shed. The matrix should be a mixed cultivation soil made of peat soil, vermiculite, and perlite, with 1-2 seeds per hole, covered with a layer of fine soil after sowing, so that the seeds are half-hidden and half-exposed, then sprayed with water to make it fully wet and placed in a high-temperature (27°C-30°C) and high-humidity (relative humidity 85%-90%) environment. After that, observe the soil temperature every day, pay attention to spray moisturizing, keep the matrix moist, prevent direct sunlight, and use 85%-90% shade netting if necessary. It usually takes 6-7 weeks to germinate, but the seedlings are not resistant to transplanting and should not be thinned. Generally, they can be transplanted when the seedlings grow larger and become crowded. It usually takes 3-4 years for the seedlings to develop leaf traps.
