CATDOLL : CATDOLL: Introduction of snapdragon

1. Introduction of snapdragon

1. Antirrhinum is a plant of the genus Antirrhinum, family Plantaginaceae. It is a perennial upright herb, with a stem base that is sometimes lignified and can reach 80 cm in height. The stem base is glabrous, with glandular hairs in the middle and upper parts, and sometimes branched at the base. The lower leaves are opposite. The racemes are terminal and densely glandular; the pedicels are 5-7 mm long; the calyx is nearly as long as the pedicel, 5-parted, with ovate lobes, obtuse or acute; there are 4 stamens, 2 of which are strong. The capsule is ovate, about 15 mm long, with a base that strongly extends forward, glandular hairs, and a pore-slit at the top.

2. Originated from the Mediterranean coast, cultivated all over the world. It is relatively cold-resistant, not heat-resistant; it likes sunlight, but also tolerates semi-shade; it likes fertile, loose and well-drained slightly acidic sandy loam; it is not sensitive to the length of light; the optimal growth temperature is 16-26℃.

3. Snapdragon is a common garden flower in China. The dwarf species is often used for cultivation in flower beds, flower borders or roadsides, and the potted plants can be placed on balconies, windowsills and other places for decoration. The tall species is often used as cut flowers and can also be used as background materials. The whole plant is used as medicine, which has the effects of clearing heat, cooling blood and reducing swelling.

Antirrhinum is a perennial herb. Latin name: (Antirrhinum majus L.) Plant height 20-70 cm, leaves oblong lanceolate. Racemose inflorescence, corolla tubular lip, base swollen into a capsule, upper lip upright, 2-lobed, lower lip 3-lobed, spreading outward. Available in white, light red, dark red, flesh color, dark yellow, light yellow, yellow-orange and other colors. Can be potted, because of its bright color, very suitable for viewing. Native to the Mediterranean region, the distribution area extends north to Morocco and Portugal, south to France, east to Turkey and Syria. Antirrhinum is named because its flowers resemble goldfish. At the same time, it is also a traditional Chinese medicine, which has the effects of clearing away heat and detoxification, cooling blood and reducing swelling. It can also be used to extract oil for consumption, which is nutritious and healthy.

Snapdragon, also known as dragon head flower, is a perennial herbaceous plant belonging to the snapdragon family. It can grow to about one meter, with upright and green stems. The leaves are flat and oval and green. Its flowering period is around July, showing various colors such as yellow, pink, white, orange, etc. The petals are about twenty, and the flowers are in clusters. Snapdragon is mainly planted in Xi'an, Suqian, Changzhou, Guangzhou, Chuzhou, Shangqiu, Hangzhou, Jinhua and other regions in my country. It mainly grows naturally in grasslands, plains, hills and other places. Snapdragon likes sunny, fertile and humid land and warm climate, with particularly good drainage and ventilation, and has very good cold resistance and drought resistance. However, it is not heat-resistant and waterlogged, and cannot be planted in waterlogged land. Planting in waterlogged land will stop its growth or wither. People often plant it in flower beds, parks, hills and other places. It has very good ornamental and greening functions.

2. Snapdragon cultivation methods and precautions

Snapdragon, also known as dragon head flower, lion flower, dragon mouth flower, foreign colorful bird, dragon head, is a perennial herb of the genus Snapdragon in the family Scrophulariaceae. It is often cultivated for one or two years or one year. So how to grow Snapdragon well? Let's learn about the cultivation methods and precautions of Snapdragon.

1. Soil:

Snapdragon is not demanding on soil, and the soil should be fertile, loose and well-drained slightly acidic sandy loam.

2. Watering:

Snapdragons are sensitive to water, so the soil in the pot must be kept moist and the potted seedlings must be watered adequately. However, the soil in the pot must have good drainage and no water accumulation, otherwise the roots will rot and the stems and leaves will turn yellow and wither.

3. Sunlight:

Snapdragon is a light-loving herb. Under full sunlight, the plant grows short, compactly, evenly, with uniform height, uniform flowering, and bright colors. Under semi-shady conditions, the plant grows taller, the inflorescence is elongated, and the flower color is lighter.

4. Temperature:

Snapdragon is relatively cold-resistant but not heat-resistant. The optimum temperature for growth is 7-10℃ from September to March of the following year, and 13-16℃ from March to September. Seedlings go through the vernalization stage at 5℃. High temperature is not good for the growth and development of Snapdragon. The optimum temperature for flowering is 15-16℃. Some varieties will not branch when the temperature exceeds 15℃, which affects the plant shape.

5. Fertilization:

Snapdragons need to strengthen fertilizer and water management. Fertilization should pay attention to the coordination of nitrogen, phosphorus and potassium. Snapdragons have rhizobia and have nitrogen fixation. Generally, nitrogen fertilizer is not needed, and phosphorus and potassium fertilizers can be added appropriately. During the growth period, fermented oil residue water should be applied once every half a month in combination with watering. When flower buds appear, it is better to spray with 0.1% to 0.2% potassium dihydrogen phosphate solution. The soil should be loosened and weeded before each fertilization.

6. Pruning:

When snapdragon seedlings grow to about 10 cm, they can be topped to shorten the plant height, increase the number of side branches, and increase the number of flowers. When pruning, cut off the weak branches, old branches, and overcrowded branches. After each flowering, cut off the branches that have bloomed to encourage the sprouting of new branches to continue flowering.

Precautions for growing snapdragon

Snapdragon is a long-day plant. Although there are many neutral varieties now, it can bloom earlier by providing 4 hours of supplementary light in winter and extending the daylight hours.

When watering, try to avoid watering from above the plant to reduce leaf wetness and the spread of diseases by splashing water droplets.

Topping should be done promptly after flowering, and fertilizer should be added. When the temperature is between 13 and 16 degrees Celsius, the plant can continue to bloom. Snapdragons are prone to natural hybridization. In order to achieve a pure variety, the mother plant for seed collection needs to be isolated.

How many times a year does snapdragon bloom?

How many times a year does snapdragon bloom? In daily life, many people grow flowers and plants, among which snapdragon is loved by many people. However, some people don’t know much about the flowering period of snapdragon. Let’s share how many times a year snapdragon blooms. Let’s take a look.

How many times does snapdragon bloom in a year? 1 Snapdragon can bloom twice a year, the first flowering period is in summer from June to July, and the second flowering period is from September to October. The flowering period is not very long, and the flower colors are rich and colorful, very bright and beautiful, such as white, red, yellow, pink, etc. During the flowering period, watering, fertilization, and light maintenance measures should be taken to promote the snapdragon flowers to bloom more beautifully.

Key points for maintenance during flowering period

1. Snapdragon does not require much water, so make sure the soil in the pot is kept moist. For example, in the summer when it is flowering, you can water it every 2-3 days, and spray water around it to keep it moist. In autumn, you can water it once a week, but be careful not to allow water to accumulate.

2. Before the flowering period, apply decomposed organic fertilizer every 10-15 days, and apply potassium dihydrogen phosphate foliar fertilizer once a month when the buds are in bloom to promote the flowers to bloom and flourish. Stop fertilizing in winter, and apply fertilizer in moderation each time without causing fertilizer damage.

3. Regardless of the growth period and flowering period of snapdragon, sufficient light environment must be maintained, which is conducive to photosynthesis, promotes the growth of branches and leaves, and the formation of flower buds, so as to achieve the purpose of more flowering. In summer, due to the strong light, it is necessary to provide appropriate shade and avoid being exposed to the sun.

How many times does snapdragon bloom in a year? 2 How to grow snapdragon

1. Full-day maintenance

Snapdragons have a high demand for light. Generally, full-sun maintenance can allow them to photosynthesize better, thus avoiding the situation of leggy branches and leaves, and blooming beautiful flowers. In addition, under sufficient sunlight, the height of the Snapdragon will be more uniform, which looks more beautiful and can be well appreciated.

2. Suitable temperature and humidity

Snapdragons prefer cool environments. The temperature should be controlled at around 15-16℃, which can make them grow better and avoid high temperatures. And pay attention to keeping the environment moist, watering in moderation to prevent the soil from drying out and turning white. When the air is dry, spray water to increase the humidity.

3. Apply thin fertilizer frequently

Frequent application of thin fertilizer to provide nutrients is the key to growing snapdragons well. During the period of vigorous growth, apply thin fertilizer solution about once every 10 days. When applying fertilizer, be careful not to splash it on the leaves, and apply it along the soil at its roots to avoid splashing and burning the leaves.

4. Timely pruning

Normally, we should control the growth rate and height of snapdragons. When the seedlings are 10cm tall, we should pinch them to prevent them from growing taller. This will help them grow better and produce more side branches and flowers. We should also prune the dense branches and remove all diseased and weak old branches.

5. Seed propagation

During the breeding process, snapdragon can be propagated by sowing. Soak the seeds in diluted potassium permanganate for 1 to 2 hours for disinfection, then take out and mix them with fine sand, and then evenly sow them on the soil disinfected with furadan. Water and sprinkle with wood ash, control the temperature to 18 to 21 degrees Celsius, and seedlings will grow in a week.
