How to propagate New Guinea impatiens? A brief introduction to propagation methods
New Guinea impatiens belongs to the Balsaminaceae family. This variety originated in the tropical mountains of Africa, but recently dwarf varieties have been bred in Japan, making it even more popular. Let me briefly introduce the main propagation methods of New Guinea impatiens.
New Guinea impatiens
Sowing, tissue culture and cuttings are the 3 main propagation methods for New Guinea impatiens. Sowing is generally done in March to April, harvesting at the right time and sowing immediately after harvest. The optimal germination temperature is 22 degrees. The tissue culture propagation method has been successful and has already begun to be produced on a large scale. In production, because New Guinea impatiens has poor self-pollination ability and tissue culture is costly, the cutting method is often used for propagation. The best seasons for cuttings are spring, summer and early autumn, and propagation can be carried out year-round in a greenhouse. Cuttings can be taken directly from the young buds in the leaf axils for micro-cuttings, and the propagation speed is quite fast; the current year's branches can also be cut into several sections, each with 2 to 3 nodes. Plain sand or vermiculite can be used as the cutting medium. To improve the rooting rate of cuttings, after quickly dipping the cuttings in ABT rooting powder, new roots are produced in 5 to 6 days, and after 2 weeks, when the roots are 2 to 3cm long, they can be potted up.
How to grow New Guinea impatiens. Propagation methods of New Guinea impatiens
New Guinea impatiens belongs to the Balsaminaceae family and is also called multicolored impatiens; the four-season impatiens is a perennial herbaceous ornamental flower of the genus Impatiens. Next, I will share with you the knowledge of how to grow New Guinea impatiens and how to propagate New Guinea impatiens.
How to grow New Guinea impatiens
Soil: New Guinea impatiens is highly adaptable to soil, and the pH value should be controlled between 5.5 and 6.5. It is best to mix leaf mold, vegetable garden soil and sand in a ratio of 5:3:2 to form a loose, fertile, well-aerated sandy potting soil.
Temperature: New Guinea impatiens likes a warm environment, and the suitable growing temperature is 20-25°C. Above 25°C the flowers will become smaller, and above 30°C the relative humidity must be increased for the plant to keep growing. When the temperature is relatively low, the growth of New Guinea impatiens stalls, and when the temperature drops below 7°C it will suffer cold damage.
Light: New Guinea impatiens likes plenty of sunlight but avoids scorching sun exposure, so appropriate shading is needed in summer. In winter, New Guinea impatiens can be placed in a bright spot indoors so it can fully receive light.
Humidity: New Guinea impatiens likes moisture and fears drought, and it also dislikes waterlogging; when water is insufficient, it easily causes flowers and leaves to drop. The potting soil should be allowed to dry and then be watered thoroughly; water as soon as it dries, and stop watering once water comes out of the bottom of the pot. Waterlogged soil will cause root rot, while excessive dryness will cause branches and leaves to wither and drop. The most important part of home care is maintaining a certain air humidity, and it is best to spray the plant with water regularly.
Fertilization: New Guinea impatiens has a long flowering period and usually needs plenty of nutrients. During the seedling stage, a little nitrogen fertilizer can be applied appropriately. During the growing period and flowering period, a nitrogen-phosphorus-potassium compound fertilizer should be applied once every 10 to 15 days. Applying nitrogen fertilizer alone is not advisable, otherwise there will be many leaves and few flowers. If fertilizer accidentally gets on the leaves during application, spray water promptly to wash it off.
Propagation methods of New Guinea impatiens
The common propagation methods of New Guinea impatiens include sowing, tissue culture and cuttings, 3 methods in total. The best time for sowing propagation is March to April each year. Because tissue culture propagation is costly, the cutting method is often used for propagation.
Cuttings of New Guinea impatiens can be done in spring, summer and autumn, and can be propagated year-round in a greenhouse. Cuttings can be taken directly from the young buds in the leaf axils for micro-cuttings, and the propagation speed is quite fast.
New Guinea impatiens can also have the current year's branches cut into several sections, each with 2-3 nodes. Plain sand or vermiculite can be used as the cutting medium. To improve the rooting rate of cuttings, after quickly dipping the cuttings in ABT rooting powder, new roots are produced in 5-6 days, and after 2 weeks, when the roots are 2-3cm long, they can be potted up.
