How to Propagate Salvia plebeia? Detailed Propagation Methods
Salvia plebeia, also known as common sage, is a very common wild plant in China. It is an annual or biennial herbaceous plant in the Lamiaceae family. Salvia plebeia has effects such as stopping diarrhea, relieving cough, reducing inflammation and promoting urination, and it is widely used in China and around the world to make swelling laxatives. There is now a certain planting area for it, so how should Salvia plebeia be propagated when cultivated? Below, the editor brings you the propagation methods for Salvia plebeia. Let's take a look!
1. Seed propagation
Seed propagation is the most commonly used propagation method for Salvia plebeia. First, try to choose the freshest seeds possible, ensuring that the fresher the seeds, the greater the germination rate. Then do the seed soaking work well, disinfect the seeds, eliminate pathogens in the seeds, and properly promote germination to further improve the seed germination rate. Prepare the seedling bed and seedling substrate, do a good job of soil preparation and disinfection, then place the treated seeds into the seedling bed. When sowing, be careful not to damage the seeds, to prevent the seeds from being injured and affecting planting benefits. After sowing, strengthen management, do a good job in a series of tasks such as temperature regulation, water and fertilizer management, and pest and disease control, to improve the seedling emergence rate. After emergence, manage the seedlings well. When the seedlings grow to 8-12 cm and have 2-4 true leaves, they can be transplanted.
2. Cutting propagation
Cutting propagation usually uses tender branches from spring and autumn as cuttings. First, prepare the cutting substrate well. The substrate can use river sand, garden soil, etc. Disinfect the substrate to prevent it from carrying pathogens. Then, during the peak growth period of Salvia plebeia in spring and autumn, select healthy, pest-free and disease-free branches as cuttings. Cut off the branches, choose the sturdy part of the branch, cut it into sections about 10 cm long for disinfection, and each section should have 3 leaf nodes. The cut above ground should be a flat cut, while the underground cut should be a slanted cut, ensuring smooth cuts to prevent infection, and finally insert them vertically into the substrate. After cutting, control various factors such as temperature, light and humidity. Among them, keep the temperature at around 25 degrees and the humidity at around 80%, creating a good growing environment for Salvia plebeia cuttings.
3. Layering propagation
Layering propagation is also a relatively commonly used propagation method for Salvia plebeia. First, choose healthy, pest-free and disease-free branches that are thick and strong with no wounds on the surface. From about 20-25 cm below the tip, girdle a layer of bark. The wound must not exceed 1 cm; simply cut off the outer bark of the branch. Then prepare plastic film, place an appropriate amount of moist garden soil on the film, wrap it around the girdled part, and tie both ends tightly. After about one month, the wrapped part will gradually take root. Once rooting is confirmed, cut off the entire branch, being careful not to damage the new roots or the original plant. After cutting it off, it becomes a new plant and can be properly planted out.
The above is a brief introduction to the propagation methods of Salvia plebeia. The planting direction of Salvia plebeia determines the different propagation methods. For example, if it is large-scale planting, seed propagation and cutting propagation are mainly used. If it is proper propagation for household potted plants, layering propagation is mainly used. Therefore, when propagating, everyone must choose the correct propagation method according to their own planting scale and direction! This article is for reference only. Thank you for reading.
