  Propagation methods

  Seed propagation

  Seed selection: Before sowing, the seeds must first be selected. Whether the seeds are well chosen directly affects whether sowing will succeed. 1. It is best to use seeds collected in the current year. The longer the seeds are stored, the lower their germination rate.

  2. Choose plump seeds with no defects or deformities.

  3. Choose seeds free of pests and diseases.

  Disinfection: Disinfection includes two concepts: one refers to disinfecting the seeds, and the other refers to disinfecting the sowing medium. For household seed disinfection, it is common to soak the seeds in hot water at about 60°C for a quarter of an hour, then use warm water to promote germination for 12-24 hours. To disinfect the sowing medium, the best method is to put it in a pot and heat it until hot; any pests or diseases will be killed by the heat.

  Germination promotion: Soak the seeds in warm water (at a temperature similar to face-washing water) for 12-24 hours, until the seeds absorb water and swell. For very common seeds that germinate easily, this step can be skipped.

  Sowing: For tiny seeds that are difficult to pick up with your hands or other tools, you can moisten one end of a toothpick with water and stick the seeds one by one onto the surface of the medium, then cover with medium 1 cm thick, and then place the sowing pot into water with the water depth at 1/2-2/3 of the pot's height, letting the water soak up slowly (this method is called the "pot immersion method"); for larger seeds that can be picked up with your hands or other tools, place the seeds directly into the medium and sow them point by point at a spacing of 3 x 5 cm. After sowing, cover with medium at a thickness 2-3 times that of the seeds. After sowing, you can use a sprayer or a fine-holed watering can to moisten the sowing medium; afterward, water again when the pot soil is slightly dry, still taking care not to water too forcefully, so as not to wash the seeds away; Management after sowing: After sowing in late autumn, early spring, or winter, when a cold wave and low temperatures occur, you can wrap the flower pot in plastic film to help keep it warm and moist; After the seedlings emerge, uncover the film in time, and let the seedlings receive sunlight before 9:30 every morning or after 3:30 in the afternoon, otherwise the seedlings will grow very weak; After most of the seeds have sprouted, proper thinning is needed: pull out the diseased and unhealthy seedlings so that the remaining seedlings have a certain amount of space from one another; when most of the seedlings have grown 3 or more leaves, they can be transplanted.

  Cuttage propagation

  Softwood cuttings are often taken from current-year branches in late spring and early autumn, or hardwood cuttings are taken from the previous year's branches in early spring.

  Cuttage medium: This refers to nutrient soil, river sand, peat soil, and other materials used for cuttings. For household cuttings, ideal cutting media are hard to obtain due to limited conditions, so it is recommended to use a ready-mixed and sterilized cutting medium; medium-coarse river sand can also be used, but it should be rinsed several times with clean water before use. Do not use sea sand or river sand from saline-alkali areas; they are not suitable for the growth of flowering plants.

  Selection of cuttings: When taking softwood cuttings, choose robust current-year branches as cuttings during the period of vigorous growth from late spring to early autumn. After cutting the branches off, select the sturdy parts and cut them into sections 5-15 cm long, each with more than 3 leaf nodes. When cutting the cuttings, note that the upper cut should be made straight across about 1 cm above the topmost leaf node, and the lower cut should be made at an angle about 0.5 cm below the lowest leaf node; both the upper and lower cuts should be smooth (the knife should be sharp).

  When taking hardwood cuttings, after temperatures rise in early spring, select healthy branches from the previous year as cuttings. Each cutting usually retains 3-4 nodes, and the cutting method is the same as for softwood cuttings.

  Management after cutting:

  Temperature: The optimum temperature for rooting of cuttings is 20°C-30°C. Below 20°C, rooting is difficult and slow; above 30°C, the upper and lower cuts of the cuttings are prone to infection by pathogens and rot, and the higher the temperature, the greater the proportion of rot. When low temperatures occur after cutting, the main measure for keeping warm is to wrap the flower pot or container used for cuttings in film; when the temperature is too high after cutting, the main cooling measure is to shade the cuttings, blocking 50-80% of sunlight, and at the same time mist the cuttings 3-5 times a day; on sunny days with higher temperatures, mist more often, and on cloudy and rainy days with lower temperatures and higher humidity, mist less often or not at all.

  Humidity: After cutting, the relative air humidity must be maintained at 75-85%. The basic requirement for rooting of cuttings is that before the cuttings root, they must be kept fresh and tender so they can carry out photosynthesis to produce rooting substances. However, cuttings that have not rooted cannot absorb enough water to maintain their internal water balance; therefore, misting must be used to reduce water evaporation from the cuttings: under shaded conditions, mist the cuttings 3-5 times a day; the higher the temperature on sunny days, the more often you should mist, and the lower the temperature on cloudy and rainy days, the less often you should mist or not mist at all. However, excessive misting makes the cuttings prone to infection by pathogens and rot, because many kinds of pathogens exist in water.

  Light: Cuttage propagation cannot do without sunlight, because the cuttings still need to continue photosynthesis to produce nutrients and rooting substances to supply their rooting needs. However, the stronger the light, the higher the temperature inside the cuttings, the more vigorous the transpiration of the cuttings, and the more water they consume, which is unfavorable for the survival of the cuttings. Therefore, after cutting, 50-80% of sunlight must be blocked. After the root system grows out, gradually remove the shade net: on sunny days, remove the shade net at 4:00 p.m. each day, and cover it again before 9:00 a.m. the next day.

  Layering propagation

  Select a robust branch, and from about 15-30 cm below the tip, remove a ring of bark. The width of the wound after peeling should be about 1 cm, and the depth should just remove the outer bark. Cut a piece of film 10-20 cm long and 5-8 cm wide, place some moistened garden soil on it, and wrap the girdled part as if bandaging a wound. Tie the upper and lower ends of the film tightly, leaving the middle bulging.

  Roots form after about four to six weeks. After rooting, cut off the branch together with its root system, and it becomes a new plant.

  Potting or transplanting: When potting young seedlings or repotting large plants that have been grown for several years, first place coarse-grained medium 2-3 cm thick at the bottom of the pot as a drainage layer, sprinkle a layer of fully decomposed organic fertilizer on top as base fertilizer, about 1-2 cm thick, then cover with a thin layer of medium about 1-2 cm thick, and then place the plant in, so as to separate the fertilizer from the root system and avoid burning the roots.

  The medium used for potting can be one of the following: vegetable garden soil: cinder = 3:1; or garden soil: medium-coarse river sand: sawdust (mushroom residue) = 4:1:2; or one of paddy soil, pond mud, or leaf mold. After potting, water thoroughly once and keep it in a shaded environment for one week of care. When transplanting young seedlings, first dig the planting hole, sprinkle a layer of organic fertilizer at the bottom of the planting hole as base fertilizer, about 4-6 cm thick, then cover with a layer of soil and place the seedling in, so as to separate the fertilizer from the root system and avoid burning the roots. After placing the seedling in, backfill the soil, cover the root system, firm the soil with your feet, and water thoroughly once.

  Humidity management: It likes a humid climate environment and requires the relative air humidity of the growing environment to be 70-80%. If the relative air humidity is too low, the lower leaves turn yellow and fall off, and the upper leaves lose their luster.

  Temperature management: Because it is native to tropical regions and likes high-temperature and high-humidity environments, it has strict temperature requirements in winter. Growth stops when the ambient temperature is below 10°C, and it cannot overwinter safely when frost occurs.

  In summer:

  1. Strengthen air convection so that the heat inside the plant can be released; 2. Place it in semi-shade, or shade it by 50%;

  3. Mist it appropriately, 2-3 times a day.

  In winter:

  1. Move it indoors to a bright place for care;

  2. Outdoors, you can wrap it in film to overwinter, but every two days at noon when the temperature is higher, uncover the film to let it breathe.

  Collapsed light management

  It likes a semi-shaded environment. In autumn, winter, and spring, it can be given plenty of sunlight, but in summer it should be shaded by more than 50%. When keeping it indoors, place it in a place with bright light as much as possible, such as a well-lit living room, bedroom, study, and similar locations. After keeping it indoors for a period (about one month), move it outdoors to a shaded place (with winter insulation conditions) for care for a period (about one month), and alternate back and forth in this way.

  Fertilizer and water management

  For potted plants, in addition to adding organic fertilizer when potting, proper fertilizer and water management should also be carried out during routine care.

  Spring, summer, and autumn: These three seasons are its peak growing seasons. Fertilizer and water management follows the cycle of "Huabao" -- clear water -- "Huabao" -- clear water, with an interval of about 1-4 days. On sunny days or during high temperatures, the interval is shorter; on cloudy and rainy days or during low temperatures, the interval is longer or no watering is done.

  Winter: During the winter dormant period, the main task is to control fertilizer and water well. Fertilizer and water management follows the cycle of "Huabao" -- clear water -- clear water -- "Huabao" -- clear water -- clear water, with an interval of about 3-7 days, and like other seasons, it needs to be adjusted according to the weather.

  For plants grown in the ground, in spring and summer, according to drought conditions, apply fertilizer and water 2-4 times: first open a small circular trench 30-100 cm away from the root crown (the larger the plant, the farther from the root crown), with the trench width and depth both 20 cm. Sprinkle 25-50 jin of organic fertilizer into the trench, or 1-5 liang of granular compound fertilizer (chemical fertilizer), then water thoroughly. After winter begins and before spring begins, apply fertilizer once more in the same way as above, but do not water.

  Pruning: In winter, when the plant enters dormancy or semi-dormancy, cut off weak, pest-damaged, dead, and overly dense branches. Branch organization can also be combined with cuttage.

  Repotting: As long as it is cared for properly, it will grow very quickly. When it grows to a certain size, consider giving it a larger pot so it can continue to grow vigorously. The culture soil and component ratio used for repotting can refer to the potting culture soil.

  Removing from the pot: Place the flower to be repotted on the ground, first pat the sides of the pot lightly with your palm so the root system is disturbed and separates from the pot wall, then turn the flower pot upside down on your left hand. Use the index finger and middle finger of your left hand to gently hold the plant, with your wrist and fingertips against the pot rim. Pat the bottom of the pot with your right hand, then use your thumb to push the root soil downward from the bottom hole to let the plant come out. After it comes out, pat the pot soil gently with both palms to let excess soil fall off.

  Flower pot preparation: Choose a flower pot of appropriate size. Cover the bottom hole of the pot with two pieces of tile or thin foam pieces, ensuring both that the pot soil is not washed out by water and that excess water can flow out in time. On top of the tile or foam, place a layer of ceramsite or crushed red bricks as a drainage layer, about 2-3 cm thick. On the drainage layer, place organic fertilizer, about 1-3 cm thick, and on the fertilizer place a thin layer of medium, about 2 cm thick, to separate the root system from the fertilizer. Finally, place the plant in, fill with nutrient soil, and leave about 2-3 cm from the pot rim.

  Key cultivation points

  ① Brunfelsia pauciflora. It likes a warm, humid climate and is not cold-tolerant. It requires plenty of sunlight and well-drained acidic loam. In winter it needs to overwinter indoors, and in spring it is moved outdoors.

  ② The culture soil can be prepared with garden soil: leaf mold: rice husk ash (1.5:1:0.5), with appropriate addition of barnyard manure. When repotting in spring, prune and shape properly, removing old roots, dead branches, dense branches, and leggy branches. In summer, it needs to be moved under large trees for cultivation.

  ③ After spring, gradually increase the amount of watering. In summer, water thoroughly once every 2 days. Mist the leaves and surrounding environment appropriately. In autumn, reduce the frequency of watering. In winter, generally water once every 10 days. Too much watering and too much indoor humidity will cause leaf drop or root rot.

  ④ In spring and summer, apply thin cake fertilizer water (20%) once every 10-15 days. Stop fertilizing from autumn to prevent new shoots from growing and suffering cold damage.

  ⑤ Propagation. a. Cuttage propagation can be done between April and August. Cut current-year branches 8-10 cm long, and they can root one month after cutting. In summer, the full-light misting method gives a high survival rate. b. Layering can also be used for propagation. Notch the branch at 15 cm, bury it in soil, and it can root after 3 weeks; after 50 days it can be separated as a seedling for transplanting.

  What to do if Brunfelsia pauciflora leaves turn yellow?

  1. Water-yellow. Yellow leaves caused by long-term watering are shown by young leaves turning yellow in sunlight without luster, while old leaves show no obvious change; the roots are small and yellow-green, and new shoots shrink and stop growing. Watering should be controlled; in severe cases, the plant can be removed from the pot, placed in a cool place to dry the soil, and then repotted.

  2. Drought-yellow. Yellowing of leaves caused by lack of water or too little watering. Old leaves wither, turn yellow, and fall off from bottom to top, but new leaves generally grow normally. The amount and frequency of watering should be appropriately increased.

  3. Fertilizer-yellow. Due to excessive fertilizing or too high concentration, the tips of new leaves appear dry brown, and the tips of old leaves become scorched, yellow, and fall off. Generally, although the leaf surface is thick and glossy, it is mostly uneven. Fertilizing should be stopped, or clear water should be used to leach out the fertilizer.

  4. Nutrient-deficiency yellow. If potted flowers are given only water and no fertilizer for a long time, or are not repotted for many years, the root hairs become tangled into a ball, and the plant cannot obtain nutrients, causing leaves to turn yellow. In addition to timely repotting, thin fertilizer should be applied frequently in normal care.

  5. Scorch-yellow. For shade-loving and moisture-loving potted flowers and foliage plants, such as spider plant, lucky bamboo, Aspidistra elatior, and Hosta plantaginea, if exposed to strong direct sunlight, the leaves often develop yellow tips and should be placed in shade.

  6. Alkaline-yellow. For acid-loving flowering plants, such as rhododendron, gardenia, camellia, osmanthus, and Michelia alba, if the pot soil or water quality is alkaline, the leaves often turn from green to yellow and even fall off. In addition to using acidic nutrient soil for cultivation, alum fertilizer water or a 0.2%-0.5% ferrous sulfate aqueous solution can be sprayed on, which can turn the leaves from yellow back to green.

  7. Damp-heat yellow. Some flowers that cannot tolerate high temperature and high humidity turn yellow because of hot summers, poor ventilation, and improper shading. For example, fuchsia and rhododendron show this phenomenon in stuffy, humid environments. Attention should be paid to ventilation and cooling, and the pot soil must not be too warm.

  8. Albino yellow. If flowers lack light for a long time, the chlorophyll in the leaves decreases, causing the green color of the leaves to gradually disappear and appear albino. The plant can be moved to a place with plenty of sunlight so the leaves slowly turn green again.

  9. In cold winter, if the indoor temperature is low, some cold-sensitive flowers, such as Michelia alba, Aglaonema modestum, and poinsettia, will also have leaves turn yellow and fall off. In addition, flowers harmed by pests and diseases can also cause yellow leaves and leaf drop. If only a few leaves at the lower part of the plant turn yellow and fall off, that is normal.

How to grow Brunfelsia pauciflora: care methods and precautions for Brunfelsia pauciflora

Brunfelsia pauciflora is also called yesterday-today-and-tomorrow. It is a plant in the Solanaceae family, native to tropical regions, and is one of the best-selling ornamental plants on the market today. Many people want to grow it at home, but do you know how to grow Brunfelsia pauciflora? Do you know what precautions there are for growing Brunfelsia pauciflora? If not, take a look at the editor's specific introduction below on growing Brunfelsia pauciflora. After reading it, everyone will know how Brunfelsia pauciflora should be grown.

This plant, Brunfelsia pauciflora, can be propagated by cuttage. Between April and August each year, cut current-year branches 8-10 cm long. They need to be cultivated in soil, and after one month they can root. After rooting, transplant them directly into a flower pot and place them in a cool environment to recover. After about one week they will survive, and then they can be moved into sunlight.

In short, Brunfelsia pauciflora requires attention to temperature regulation. It grows best in an environment of 18-30°C, and when cultivated indoors, it must receive four hours of sufficient sunlight every day, otherwise its flowering period will be directly affected. When the outside temperature reaches 12°C, it will enter a dormant state. In normal care of Brunfelsia pauciflora, water regulation is also very important. In hot summer weather, it should be watered once every two days, and water should also be applied to its leaves. After entering autumn and winter, water supply should be reduced, and watering once every ten days is enough.

Brunfelsia pauciflora is an ornamental plant that likes a warm and humid climate, and its cold tolerance is especially poor. In normal care of Brunfelsia pauciflora, special attention must be paid to this point: when winter arrives, move it indoors to a warm place. In addition, when growing Brunfelsia pauciflora, note that it should be repotted once a year. Repotting can be done in spring. When repotting, the branches should be pruned and shaped, and its old roots and dead roots should be removed, so that Brunfelsia pauciflora can grow more vigorously in the new year.
