Cultivation Methods for February Orchid

February Orchid, also known as Zhuge Cai. A biennial herb in the Brassicaceae family. Native to North China and Northeast China.

   Morphological characteristics: Plant height 40〜60 cm. The stem is smooth and covered with white powdery bloom. The basal leaves are nearly round, the middle leaves are more strongly pinnately lobed, and the terminal leaves are narrow and long, triangular-ovate, with serrated edges. Racemose inflorescence, flowers small, petals obovate, with a long claw, flower color blue or white, also blue-white intermediate colors. Seeds small, round.

   Growth habits: February Orchid grows robustly, has strong cold resistance, is relatively tolerant of poor soil, and is not strict about soil requirements, but well-drained fertile loam is better. It likes light and is relatively shade-tolerant. It blooms in late February.

   Propagation method: Propagated by sowing. In autumn, from September to October, direct sowing is carried out. Often after one sowing, it can self-sow and reproduce naturally every year, forming a whole patch of natural flowers.

   Cultivation and care: During the seedling stage, pay attention to watering and care, and remove weeds. After the seedlings are established, stress resistance is strong. After flowering and seed pods split, simply remove and destroy the residue.

   Pest and disease control: February Orchid grows robustly and blooms especially early, so even if white butterfly larvae occur, they do not hinder its growth and ornamental value. Extensive care is sufficient.

   Horticultural use: Often used as natural flower patches arranged in courtyard corners.

Key Points of February Orchid Planting Methods, Precautions for Planting February Orchid

February Orchid has strong cold resistance and remains evergreen in winter. It is also relatively shade-tolerant. Used as ground cover, it has a good covering effect, with lush green leaves and a sheet of jade green that people love. It has strong adaptability and can grow from Northeast China and North China all the way to East China and Central China. In winter, if there is heavy frost and snow, some leaves may freeze, but in early spring they can still sprout new leaves, bloom, and set seed. It is not strict about soil requirements.

February Orchid has extremely strong vitality and strong adaptability to the northern environment, especially in winter, and can endure the northern winter with very strong cold resistance. February Orchid especially likes shady and moist growing environments and has low requirements for water and light. In terms of soil, it is suitable for growing in slightly alkaline soil. It is a type of plant that remains evergreen all year round. It is the first to bloom in early spring, carrying the meaning of announcing the arrival of spring. It is a very plain and lovely plant.

Zhuge Cai is mainly propagated by seed and has strong regeneration ability. After the plant withers, newly dropped seeds will soon germinate and grow into new plant seedlings. On soil that has not been plowed, artificially broadcast seeds can also develop into seedlings, and it has strong weed resistance. Therefore, cultivation management can be relatively extensive and fairly easy. Some freshly harvested seeds have a after-ripening physiological phenomenon, and early sowing has a low germination rate, with germination continuing for 1-2 months or even longer. Sowing time can be in summer or autumn, but August to September is most suitable. Each gram contains 300-400 seeds, and the sowing rate per mu is about 1 kg. If calculated per square meter, it should be 1-2 grams per square meter. If the spray-sowing method is used, the amount per unit area should preferably be increased by 10-20%.

The potting soil is made by mixing garden soil, perlite, and plant ash evenly in a ratio of 6:2:1. When potting, apply sufficient base fertilizer. After the seedlings stand upright, move the pot to a sunny place for routine fertilizer and water management.

Compared with other flowers, cultivation management is relatively extensive and does not require much care. It has strong cold resistance and shade tolerance, and can grow, bloom, and set seed normally with a certain amount of scattered light. It is not strict about soil requirements. It is best to choose loose, fertile, and well-drained sandy soil. As long as it is watered and fertilized in time, it can grow robustly with only a little management. Fertilize 4 times a year. Flower bud fertilizer in early spring, robust-growth fertilizer after flowers fade, fruit-strengthening fertilizer after fruit set, and seedling-strengthening fertilizer before winter. If a 0.2% monopotassium phosphate solution is sprayed on the leaves once each during the bud stage and young fruit stage, the flower color will be more brilliant and the fruit will be fuller. The flowering period is from early spring to June. The silique is elongated, maturing in June. Seeds are black-brown and ovate. In winter, Zhuge Cai has lush green leaves, and in early spring the flowers bloom in patches. If there is heavy frost in winter, frost protection measures need to be strengthened. If it is for food use, it should be divided frequently to promote the sprouting of tender stems and leaves.

1. Soil: February Orchid is not strict about soil requirements. It is best to choose loose, fertile, and well-drained sandy soil. For potted February Orchid, the requirements for potting soil are relatively high. Here you can consider using 6 parts garden soil, 2 parts perlite, and 1 part plant ash, mixed evenly, and sufficient base fertilizer should be placed in the pot.

2. Light: Since February Orchid is a short-day plant, it does not need long daily sunlight. Scattered light indoors is sufficient.

3. Temperature: Since February Orchid is cold-resistant, temperature regulation can be extensive. The most suitable temperature for growth and flowering is between 15°C and 25°C.

4. Fertilization: February Orchid likes fertilizer. Sufficient fertility will not only make February Orchid grow faster, but also promote its flowering and fruiting. Fertilize 4 times a year. Flower bud fertilizer in early spring, robust-growth fertilizer after flowers fade, fruit-strengthening fertilizer after fruit set, and seedling-strengthening fertilizer before winter. If a 0.2% monopotassium phosphate solution is sprayed on the leaves once each during the bud stage and young fruit stage, the flower color will be more brilliant and the fruit will be fuller.

5. Pruning: To keep a wildflower mix always showing a good ornamental effect in landscape arrangements, it must be controlled so that it does not set seed. Generally, during the seed-setting period, use a lawn mower to prune it to a height of 10-15 cm. In addition, when preparing the land for autumn sowing, remove ground debris that hinders good contact between seeds and soil, including dead branches and fallen leaves. At present, in the field of landscape greening, creating natural and diverse garden landscapes, exploring plant application forms that return to simplicity and nature, and building a resource-saving and sustainably developing ecological environment are the direction of future development. Wildflower mixes can create natural and beautiful landscape effects, and with the characteristics of extensive management, rich species, full wild charm, low establishment cost, and long ornamental period, they will become the most distinctive element in the field of landscape greening and be most widely used.

Sowing precautions: Sowing time can be in summer or autumn, but August to September is most suitable. Each gram contains 300-400 seeds, and the sowing rate per mu is about 1 kg. If calculated per square meter, it should be 1-2 grams per square meter. If the spray-sowing method is used, the amount per unit area should preferably be increased by 10-20%.

6. Pests and diseases: Common pests in February Orchid planting include aphids, cabbage caterpillars, snails, leaf miners, and others. If pests are found, timely chemical control should be carried out.

a. Symptoms: In the early stage of the disease, yellow-green, polygonal spots appear on the leaf surface. Subsequently, a white downy mildew layer forms on the underside of the lesions, causing swelling, curling, and greening of the petals on stems and flowers.

b. Pathogen: The pathogen is a fungus in the genus Peronospora. This disease mostly occurs on the lower leaves of February Orchid. Especially in April, when the weather is cold, cloudy, and humid, plants are more likely to be infected. Overcrowded planting can also lead to the occurrence of this disease.

c. Diagnosis and countermeasures: Choose a site with good ventilation and light transmission for planting. Planting density should be reasonable. Spray 50% mildew cure 500 times dilution.

7. Weed management

Water before sowing to promote the germination of weed seeds in the topsoil. If soil moisture is moderate, seeds can germinate within two weeks. Do not plow the soil again, otherwise more weed seeds will be brought to the surface soil. Applying herbicide spray can basically eradicate weeds, but be sure to rest for a period after applying herbicide before sowing, because herbicides are harmful to any plant.

When using chemical herbicides, be sure to pay attention to safety and avoid chemical residues affecting the germination and growth of flower seeds. Therefore, generally before sowing wildflower mix seeds, a 3-4 week recovery period should be reserved for the soil, and then the wildflower mix should be planted, because widespread use of herbicides may cause delayed seed germination or weakened growth vigor of flower seedlings.

Remove weeds promptly when flower seeds germinate to prevent them from spreading. If conditions permit, weeds should be pulled out immediately as soon as they are found. In addition, a relatively effective method is to use broad-spectrum herbicides or cut them with a weed cutter (or brush cutter). Make sure to remove weeds before they drop seeds. Many annual or perennial weeds can be controlled with specialized herbicides. These herbicides will not affect the growth and development of broadleaf plants and can be used on wildflower mixes. Spraying them on newly grown seedlings works very well.
