What are the cultivation methods and precautions for New Guinea Impatiens
The propagation of New Guinea Impatiens includes 3 methods: sowing, tissue culture, and cuttings. The sowing propagation time is generally in March-April, harvested at the right time, and sown immediately after harvesting. The suitable germination temperature is 22 degrees.
The tissue culture propagation method has been successful and has begun large-scale production. In production, because New Guinea Impatiens has poor self-pollination ability and tissue culture costs are high, the cutting method is often used for propagation.
The cutting season is preferably 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; current-year branches can also be cut into several sections, each with 2-3 nodes. The cutting medium can be plain sand or vermiculite. To improve the rooting rate of cuttings, after the cuttings are quickly dipped in ABT rooting powder, new roots are produced in 5-6 days, and after 2 weeks, when the roots are 2-3 cm long, they can be potted.
The suitable cultivation temperature for New Guinea Impatiens is 16-24 degrees. Temperatures below 15 degrees or above 32 degrees will affect normal growth, and the light requirement is 30,000-50,000 lx. If the temperature is suitable, it can bloom year-round. New Guinea Impatiens requires meticulous management, and watering should follow the principle of “dry-wet alternation”. Spraying foliar fertilizer once every 7-10 days or applying diluted composted fertilizer water once every half month will make its growth even more pleasing.
2-3 weeks after planting, when the seedlings reach 10-15 cm in height, apply compound fertilizer at 0.5 g/l, in small amounts and multiple times; if nutrients are excessive, brown spots will appear on the leaves, and the nitrogen content of the fertilizer should be controlled at 50-100 mg/l. When light is strong, the flowers bloom earlier and smaller; at this time, pinch frequently to accumulate nutrients and promote side branches, making the plant shape fuller.
Temperature and light: New Guinea Impatiens likes warmth and sufficient light, is not cold-tolerant, and avoids exposure to scorching sun. The suitable growth temperature is around 20 degrees; above 25 degrees Celsius the flowers will become smaller, and above 30 degrees Celsius the relative humidity must be increased to allow the plant to continue growing. When the temperature is relatively low, plant growth stops, and when the temperature drops below 7 degrees Celsius, it will suffer cold damage.
Soil and humidity: It likes moisture and fears drought, and avoids waterlogging. When water is insufficient, it easily causes flowers and leaves to drop. It has strong adaptability to soil, and the pH value should be controlled between 5.5 and 6.5. It is best to use leaf mold, garden soil, and sand mixed in a ratio of 5:3:2 into a loose, fertile, well-aerated sandy culture soil. The pot should not be too large. The potting soil should follow dry-wet alternation; water when dry, and stop watering when water comes out of the bottom of the pot. Waterlogging will rot the roots, and 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 advisable to spray water on the plant frequently.
Cultivation Methods of New Guinea Impatiens Propagation Methods of New Guinea Impatiens
New Guinea Impatiens belongs to the Balsaminaceae family, also called multicolored impatiens; four-season impatiens is a perennial herbaceous ornamental flower of the genus Impatiens. Next, I will share with you knowledge about the cultivation methods of New Guinea Impatiens and the propagation methods of New Guinea Impatiens.
Cultivation Methods of New Guinea Impatiens
Soil: New Guinea Impatiens has strong adaptability to soil, and the pH value should be controlled between 5.5 and 6.5. It is best to use leaf mold, garden soil, and sand mixed in a ratio of 5:3:2 into a loose, fertile, well-aerated sandy culture soil.
Temperature: New Guinea Impatiens likes a warm environment, and the suitable growth temperature is 20-25 degrees C; above 25 degrees C the flowers will become smaller, and above 30 degrees C the relative humidity must be increased to allow the plant to continue growing. When the temperature is relatively low, the growth of New Guinea Impatiens stops, and when the temperature drops below 7 degrees C, it will suffer cold damage.
Light: New Guinea Impatiens likes sufficient sunlight and avoids exposure to scorching sun, so proper shading is needed in summer. In winter, New Guinea Impatiens can be placed in a bright indoor spot so it can fully receive light.
Humidity: New Guinea Impatiens likes moisture and fears drought, and avoids waterlogging. When water is insufficient, it easily causes flowers and leaves to drop. The potting soil should follow dry-wet alternation; water when dry, and stop watering when water comes out of the bottom of the pot. Waterlogging will rot the roots, and 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 advisable to spray water on the plant frequently.
Fertilization: New Guinea Impatiens has a long flowering period and usually needs many nutrients. During the seedling stage, an appropriate amount of nitrogen fertilizer can be applied. During the growth period and flowering period, a nitrogen-phosphorus-potassium compound fertilizer should be applied once every 10 to 15 days. Do not apply nitrogen fertilizer alone, otherwise there will be more leaves and fewer flowers. If fertilizer accidentally gets on the leaves during application, promptly spray water to wash it off.
Propagation Methods of New Guinea Impatiens
The common propagation methods of New Guinea Impatiens include 3 methods: sowing, tissue culture, and cuttings. The best time for sowing propagation is March-April each year. Because tissue culture propagation costs are high, the cutting method is often used for propagation.
Cuttings of New Guinea Impatiens can be carried out 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 current-year branches cut into several sections, each with 2-3 nodes. The cutting medium can be plain sand or vermiculite.
