When to sow larkspur? A detailed guide to growing and care methods

How do you grow larkspur? Why does larkspur have this name? As the name suggests, it is because of its unique flower shape. Larkspur originates from southern Europe, and it is now cultivated in many provinces in China. Below, the editor will briefly explain the key points of larkspur growing methods.

1. Morphological characteristics

Larkspur is a perennial herbaceous plant in the genus Consolida of the Ranunculaceae family, also known as qianniaohua, pigeon flower, large-flowered larkspur, and so on. The flowering plant is generally about 35-65 cm tall, with a flower diameter of about 4 cm, and the flowering and fruiting period of larkspur is generally from August to October. The beautiful larkspur is actually also a Chinese herbal medicine. The whole plant and seeds of larkspur can treat toothache, and the stems and leaves can also be soaked to make a liquid that kills insects.

2. Environment

Larkspur prefers a sunny, humid and cool growing environment. It is relatively cold-tolerant, slightly tolerant of semi-shade, drought-tolerant, and not tolerant of high temperatures or waterlogging. It grows well in deep, fertile sandy soil.

3. Water and fertilizer

During the growing period, larkspur should be watered by the principle of watering when dry and letting it dry between waterings. During the flowering period, it needs a little more water to avoid the soil becoming too dry. In the rainy season, remember to drain water promptly to avoid water accumulation.

When repotting larkspur plants, organic dry manure can be applied as a base fertilizer. During the vigorous growth period, remember to apply decomposed cake fertilizer water once every half month. During the flowering period, apply more phosphorus and potassium fertilizer, which can promote abundant flowering.

4. Height control and staking

After changing the potting soil in spring, apply 0.5% paclobutrazol once every 2 weeks to control the plant height. When the plant is 20 cm tall, a support net can be set up to prevent lodging. Seeds should be collected promptly after they mature to avoid the seed pods splitting after ripening.

5. Sunlight

Larkspur likes a sunny environment, especially during the flowering period. In hot summer, this is not necessary, and more water can be sprinkled to lower the temperature. Potted larkspur needs shade at noon and enhanced ventilation. In winter, water should be controlled, and giving sunlight during the day or adding lighting in a greenhouse can also make it bloom earlier.

6. Propagation temperature

Larkspur is propagated by seeds and cuttings, both of which can be done in spring and autumn. Generally, division is done once every 2-3 years. For autumn sowing, mid-September is best. After entering October, increase lighting, and it will bloom from May to July the following year. The suitable temperature for seed germination is 15°C. The suitable growing temperature is 20-25°C during the day and 3-15°C at night.

7. Management

During the high-temperature period in summer, prevent larkspur from becoming damp. Do not let the plants become too dense. Promptly prune diseased and withered branches and keep ventilation good, with light and air penetration; otherwise, it is prone to fungal diseases. Under conditions of abundant rain and moist soil, the disease is more severe, so take care to prevent it.

The above are all the key points for growing larkspur. Do you like the beautiful and elegant larkspur? Flower growers who have the conditions can try growing it.

In recent years, as people pay more and more attention to improving their quality of life, all kinds of plants and flowers have gradually entered our daily lives. Larkspur may still be relatively unfamiliar to some friends. It is a plant with a very unique and distinctive flower shape. Its form is elegant and very lovable, so it is one of the plants that are very popular among people today. Below, let us take a look at the flower meaning of larkspur and the complete guide to larkspur growing methods.

What is larkspur

First, let us briefly understand what larkspur is. Larkspur, scientific name Consolida ajacis (L.) Schur, is also called pigeon flower, baibu grass, or qianniaohua, among other names. It is a perennial herbaceous plant in the genus Consolida of the Ranunculaceae family. The flower shape of larkspur is very distinctive. From a distance, it looks like swallows taking flight one after another, which is why people call it larkspur. The plant was originally native to the southern part of Europe. After continuous cultivation and development, it is now cultivated in all provinces in China. In addition, larkspur also has relatively high medicinal value. Its whole plant and seeds can both be used as medicine, and it is understood to be able to treat toothache.

At present, people mainly define the flower meaning of larkspur as purity, lightness, justice, and freedom. Among them, the meanings of purity and lightness come from larkspur itself, because its shape is distinctive and it looks very small and lovely, while the flower posture is elegant and unique, so it has the beauty of purity and lightness. The meanings of justice and freedom mainly come from the legend of larkspur. It is said that in distant ancient times, a group of people was persecuted.

1. Usually, larkspur propagation methods are seed propagation and cutting propagation. Among them, seed propagation is usually autumn sowing, that is, from late August to early September each year, while cutting propagation can be done in both spring and autumn. Generally, division is done once every 2 to 3 years. Larkspur is a plant that loves sufficient sunlight and a cool environment. During cultivation, attention should be paid to placing the plant in a sunny spot. Only with sufficient sunlight can the plant carry out photosynthesis and then produce brightly colored flowers. At the same time, keeping the growing environment cool and well ventilated is also very important.

2. Larkspur itself is both cold-tolerant and drought-tolerant, but the plant also has weaknesses, namely that it is not tolerant of high temperatures or wet conditions. Therefore, the points to pay attention to during cultivation are the plant's growing temperature and moisture. During daily cultivation, the surrounding temperature should not be too high. The best daytime growing temperature is between 20 and 25°C, and at night it should be controlled between 3 and 15°C. In terms of watering, the plant likes moisture but is not tolerant of wetness, so watering should follow the principle of watering when dry and letting it dry between waterings, meaning it is enough to water when the soil is dry. In addition, larkspur does not have high demands for soil and fertilizer. When repotting, applying some dry manure as a base fertilizer is enough.

Conclusion: Larkspur is a very elegant plant. Its flower shape is like swallows dancing gracefully one after another, making it very lovable, so it looks very unique and beautiful. It has good ornamental value, and placing it indoors has a very good decorative effect.

Larkspur is a perennial herbaceous plant in the genus Consolida of the Ranunculaceae family. It is native to southern Europe and is cultivated in all provinces in China. Because its flower shape is distinctive and closely resembles swallows one after another, it is named after them. Its flower diameter is about 4 cm. Its form is elegant and lovable. It is often planted in flower beds and flower borders, and can also be used as a cut flower. Below, let us take a look at larkspur growing methods.

Larkspur growth habits

Larkspur has strong adaptability to climate, and a humid and cool climate environment is more suitable. The suitable temperature for seed germination is 15°C. The suitable growing temperature is 20-25°C during the day and 3-15°C at night. It likes light and can tolerate slight shade. During the growing period, it can be placed in semi-shade, while during the flowering period it needs sufficient sunlight. It likes fertile, moist, acidic soil with good drainage, and can also tolerate drought and slightly tolerate water temperature. A pH value of 5.5-6.0 is best.

Larkspur propagation methods

Larkspur can be propagated by seeds or cuttings. For autumn sowing of seeds, sow from late August to early September. First sow in an open-field seedbed, and before winter enter a cold frame or cold room to overwinter, then plant out after spring warms up. In the south, direct sowing in the open field in early spring, with thinning to maintain a plant spacing of 25-5 cm. In the north, seedlings are generally raised in advance and planted out in mid-April. Transplant when there are 2-4 true leaves, and plant out when there are 4-7 true leaves. Pay attention to drainage on rainy days. Cutting propagation is carried out in spring. When new leaves grow to more than 15 cm, cut cuttings and insert them into sandy soil. Division propagation can be done in both spring and autumn, generally once every 2-3 years.

Larkspur growing methods

1. Care: After sowing larkspur, the soil must be kept moist. The simplest method is to cover it with some grass, and gradually remove the covering after the seedlings emerge.

2. Transplanting: When larkspur grows 2 true leaves, transplant it with soil into a small pot, and change the pot once more after the seedlings grow larger.

3. Watering: Water larkspur by the principle of watering when dry and letting it dry between waterings. During the flowering period, water a little more appropriately to avoid the soil becoming too dry.

4. Fertilizing: When repotting larkspur, apply dry manure as a base fertilizer. Afterward, according to growth conditions, apply decomposed cake fertilizer water 1-3 times a month.

5. Height control: After repotting larkspur, use paclobutrazol to control plant height. The specific method is to apply 0.5% paclobutrazol once every 2 weeks.

6. Seed collection: Collect larkspur seeds promptly to avoid the seed pods splitting after ripening.

7. Diseases: Common larkspur diseases include black spot, crown and root rot, and chrysanthemum leaf blight nematode, which harm leaves, flower buds, and stems. They can be prevented and treated by spraying with 500 times dilution of 30% thiophanate-methyl wettable powder.

8. Pests: Common larkspur pests include aphids and noctuid moths. Spray with 2000 times dilution of 10% chudongjing emulsifiable concentrate to kill them.
