A Detailed Guide to the Growing Conditions and Cultivation Techniques of Impatiens
Impatiens is also known as nail flower, touch-me-not, daughter flower, golden phoenix flower, and so on. It belongs to the Balsaminaceae family and is an annual herb. The stem is upright, and plant height ranges from 30 to 80 cm. The stem is thick, succulent and smooth, with swollen nodes, and is green or dark brown. Stem color is related to flower color. Leaves are alternate, narrowly lanceolate, with fine serrations along the edges. Flowers are borne singly or in clusters of several in the leaf axils. There are 3 sepals; the two lateral ones are smaller, and the rear one is large and extends outward to form a spur. There are 5 petals, with two pairs fused so they appear as 3 petals, or they may be double. Colors include white, pink, red, purple or variegated, and petals sometimes have stripes and spots. The flowering period is from June to October. The capsule is pointed-ovate, and the seeds are round and yellowish-brown, easily splitting open on their own when mature.
Impatiens likes heat and fears cold, has strong adaptability, and can reproduce by self-sowing. The whole plant can be used as medicine. The flowers are mainly used for snake bites and referred pain in the waist and ribs; the roots and leaves can disperse blood and unblock menstruation.
Most of the plants on the flower market now are New Guinea impatiens. New Guinea impatiens is a perennial evergreen herbaceous plant in the genus Impatiens of the family Balsaminaceae. It has rich flower colors and bright, cheerful hues, blooms in all four seasons, with abundant flowers and a long flowering period; the plant is full and well-formed, and the leaves are clean and beautiful, with uniquely distinctive leaf color and shape; it grows quickly and can naturally take shape, making it suitable as a fashionable potted flower supplied year-round.
Growing Conditions
The ideal temperature for vegetative growth is 22°C-25°C during the day and 20°C-21°C at night; after 5 weeks, for tall plants use 24°C-26°C during the day and 18°C at night, and for compact plants use 20°C-21°C during the day and 18°C at night; a night temperature of 18°C is the ideal temperature for flower differentiation and development, especially under low light; when daytime temperatures exceed 28°C-29°C, shade should be provided, otherwise flower size will be reduced. Temperatures below 15°C or above 32°C will affect normal growth. Plenty of light is needed, but strong light should be blocked in summer.
Cultivation Techniques
Finished flowering plants are usually grown in 10-15 cm pots; the substrate should be loose and airy and have a certain water-holding capacity. It is very sensitive to salt damage, so it is best to apply thin fertilizer frequently. Avoid overwatering or drought. The optimal pH is 5.8-6.5. To make the plant fuller in shape, pinching should be carried out.
Fertilizing and Watering
Use 50-100 ppm nitrogen fertilizer for the first three weeks, then 100 ppm nitrogen fertilizer for the next three weeks, and afterward fertilize according to soil analysis. Water once every two weeks afterward to avoid salt damage. Twisted, dark green and curled leaves are a sign of excessively high salinity. The use of slow-release fertilizers and micronutrients often leads to toxicity.
Pest and Disease Control
The main diseases are gray mold, pythium rot, rhizoctonia and powdery mildew. Low salinity and appropriate watering can avoid pythium rot. Pests: before flowering, always pay attention to the control of thrips, spider mites (curled growing points) and fungus gnats, otherwise the application of insecticides during the flowering period will affect flower development. Drenching the roots with 35 ounces/100 GAL of pesticide can control fungus gnats.
Precautions
The problems that easily occur during cultivation are mainly delayed flowering or no flowers: lack of light, excessively high night temperature (above 20°C), and excessive nitrogen fertilizer are the three causes, and these three often occur at the same time; failure to root or initial failure to grow, root rot, overly wet substrate, and often low temperature (below 20°C), and sometimes excessive salinity; if only some plants fail to grow, fungi and gnats may be a cause. Sterile flowers or few flowers: usually caused by low light and high night temperature (night temperatures above 20°C), and it is more serious when both occur at the same time; high nitrogen fertilizer, especially high ammonium nitrogen fertilizer, can also cause it, and it will be more serious when the above conditions occur at the same time.
Impatiens Planting/Cultivation Methods and Pictures of the Impatiens Growth Process
Impatiens is a herbaceous plant belonging to the family Balsaminaceae, and it mainly grows in China and India. With the development of society, impatiens has also entered the indoors and outdoors of many homes, and we can see impatiens smiling at us everywhere. As it grows, the flower head, flower leaves, flower branches and flower base are all elegantly lifted, dancing like a phoenix. Its vitality is very tenacious, and it will bloom and bear fruit. It not only beautifies people's environment and freshens the air, but also has good medicinal value and is very good for people's health. Below let us look at the planting/cultivation methods of impatiens, and enjoy pictures of the impatiens growth process, so that more people can learn about impatiens.
Introduction to Impatiens
Impatiens is also called nail flower, touch-me-not, impatiens stem, and so on. It is an annual herbaceous flower, and it is composed of six parts: root, stem, leaf, flower, fruit and seed. Its flower colors are also very numerous, including pink, bright red, purple, pink-purple, and so on. It is a flower used for dyeing fingernails and is loved by many girls. Its stem has a certain medicinal value, especially with good effects on dispelling wind-dampness, promoting blood circulation, relieving pain, treating dysphagia, fish bones stuck in the throat, abdominal masses and amenorrhea, and so on. The stem is very thick and upright, and also very fleshy. It not only has good ornamental value, but its medicinal value is also very good.
The Ecological Environment of Impatiens
Impatiens is suitable for growing in places with ample sunlight, and it is relatively afraid of moisture, with a habit of tolerating heat but not cold. It is suitable for growing in loose, fertile, sunny places, and it can also grow in relatively poor soil; its requirements for soil are not particularly high. Its growth ability is very strong, and it is rarely attacked by viruses. In hot and humid climates, powdery mildew may appear. At this time, 50% carbendazim wettable powder at 800 times dilution can be sprayed for control, and it can also treat leaf spot disease. Impatiens is a flower plant with relatively high ornamental value, generally planted in places such as Jiangsu, Zhejiang, Hebei, Anhui, and so on, and generally planted in courtyards.
Planting Methods for Impatiens
1. Soil: Spring is the most suitable time to plant impatiens, and it needs soil with ample sunlight, moisture, looseness, fertility and good drainage. When planting, base fertilizer can be applied, and raised beds or flat beds can be made, with a width of 1.2 m.
2. Temperature and light: Impatiens likes light and can grow in shady places, and it needs at least four hours of diffused light per day for photosynthesis. In summer it should be shaded, and in winter it is best to place it indoors to prevent freezing.
3. Watering: After the impatiens is planted, it can be watered. During cultivation, it must not be alternately dry and wet. Under strong light it is not suitable to water the impatiens. During the flowering period it must not suffer drought, otherwise the flowers will drop.
4. Fertilizing: When impatiens seedlings are 30-40 cm tall, remove the old leaves and remove the growing tip to promote more branching, then fertilize, and cake fertilizer is best. A furrow can be opened along the row, the fertilizer placed in the furrow, then covered with soil and watered.
5. Weeding: While impatiens is growing, weeds are also growing. To prevent weeds from taking water, loosen the soil and weed. Weeding can be done 2-3 times a year.
6. Controlling the flowering period: If you want to delay the flowering period, you can sow in July, or you can use the pinching method, removing open flowers or flower buds so that the plant cannot spread out. Apply fertilizer once every half month. This practice can delay the flowering period to National Day for people to enjoy.
Summary: The above is the planting/cultivation methods of impatiens and pictures of the impatiens growth process introduced to you by the editor. I hope more people can learn about impatiens and grow it very luxuriantly, thereby beautifying their environment, freshening the air, and letting everyone live healthily and happily. Thank you for reading and enjoying.

How to plant impatiens? Planting methods and cultivation techniques for impatiens
Planting Methods and Cultivation Techniques for Impatiens
Impatiens likes sunny sites and loose, fertile soil, and it can also grow in relatively poor soil.
Impatiens is propagated by seed. Sow from March to September, with sowing in April being the most suitable, so that it can bloom in early to mid-June, and the flowering period can last more than two months.
Site Selection and Land Preparation
Soil with ample sunlight, moisture, fertility, looseness and good drainage is suitable. Apply base fertilizer, prepare the land and make beds. Make raised beds in the south and flat beds in the north, with a bed width of 1.2 m.
Sowing Methods
The seeds are tiny and have a long lifespan; stored at room temperature for 3 years, their germination rate still reaches 79.7%. Direct sowing: March in the south, April in the north. With a row spacing of 35 cm, open a shallow furrow of 1 cm, evenly scatter the seeds into the furrow, cover with soil and press lightly, then water. After sowing, keep the soil moist. At about 25°C, seedlings begin to emerge in about 5 days. The seeding rate is 500 g per 667 sq m.
Thinning: Thin the seedlings when they are 5-10 cm tall, removing small, weak and overly dense seedlings, and final thinning at a plant spacing of 20 cm. Reasonable close planting can give high quality and high yield.
Raising Seedlings
Scatter the seeds on the culture soil and lightly cover with about 0.3 cm of soil. They germinate after 5-6 days. When there are 3-4 true leaves, they can be planted in flower pots or flower beds at a plant spacing of 30 cm.
Flowering Period Control
If you want to delay the flowering period, you can sow in early July. You can also use the pinching method, while also removing early-opening flowers and flower buds, so that the plant continuously expands, and topdress once every 15-20 days. After September, more flower buds will form, so that they bloom on National Day.
Cultivation and Weeding
After emergence, to prevent weeds from competing for water, loosen the soil and weed in good time. Water promptly in dry weather. Cultivate and weed 2-3 times a year.
Topdressing
When the seedlings are 30-40 cm tall, the old leaves on the lower part of the stem can be removed, and the growing tip pinched off, to encourage more branching. At this time, apply 40 kg of cake fertilizer per 667 sq m. A furrow can be opened along the row, the fertilizer scattered into the furrow, covered with soil, and watered. Pay attention to drainage in hot and rainy seasons.
