When is the latest sowing time for garlic chives

Garlic chives belong to the lily family and are a perennial root vegetable with strong adaptability, cold and heat tolerance, and are cultivated everywhere in our country. In many areas of the south they can be produced year-round, while in the north, although the aboveground parts die in winter, the underground parts enter dormancy and can continue to sprout and grow after the topsoil thaws in spring. Now let us take a look at when garlic chives are sown!

When are garlic chives sown?

Garlic chives can be sown at any time from when the soil thaws to the Autumn Equinox, generally with spring sowing as the main method. In the Huang-Huai River basin, spring sowing of garlic chives is from early April to mid-April; in the south, from December to February; in the north, from May to June. When the ground temperature is stable above 12°C and the daily average temperature is 15-18°C, they can be sown. Using drilling, each mu of seedbed uses 6-8 kg of dry seed, which can plant 6000 sq m of vegetable land. Immediately after sowing, cover with plastic film to keep and raise the temperature, and remove the film when 70% of the seedlings have emerged through the soil.

What sowing periods do garlic chives have?

1. Spring sowing: Garlic chives should be sown early in spring rather than late. In spring, when the local ground temperature is stable at 5-10°C, they can be sown. At this time the ground has not completely thawed through, the soil return period has not arrived, the surface is relatively moist, seedlings emerge easily, and weed damage is also avoided.

2. Summer sowing: Garlic chives are generally sown in summer after cucumbers and tomatoes are cleared from the field. At this time temperatures are high and drought and waterlogging easily occur. The sowing rate should be about one third greater than in spring, and the soil cover should not be too thick. Keeping the soil moist helps achieve full seedling emergence.

3. Autumn sowing: Garlic chives are generally sown in autumn around the Beginning of Autumn. The sowing rate should be twice that of spring. Management is mainly based on drying and wetting alternately. Later, attention should be paid to weed damage, but autumn sowing is generally not recommended.

What growth stages do garlic chives have?

1. Germination stage: From sowing to the unfolding of the first true leaf is the germination stage for garlic chives, generally requiring 10-20 days. During this period, attention should be paid to sowing quality to create good conditions for germination and emergence.

2. Seedling stage: From the unfolding of the first true leaf to transplanting is the seedling stage for garlic chives, requiring 40-60 days. During this period the aboveground part grows slowly while the root system grows faster. In production, attention should be paid to weeding and thinning seedlings, with appropriate irrigation and topdressing to promote vigorous growth of the seedlings.

3. Vegetative stage: From transplanting to flower bud differentiation is the peak vegetative growth stage of garlic chives. After a short period of recovery, the plants successively produce new roots and grow new leaves, entering the peak growth stage. During this period, fertilizer and water management should be strengthened.

What conditions are needed to grow garlic chives?

1. Temperature: Garlic chives prefer cool conditions, but are tolerant of both cold and heat. The suitable temperature for seed germination is above 12°C, the growth temperature is 15-25°C, and the underground parts can tolerate relatively low temperatures.

2. Light: Garlic chives have strong shade tolerance. If light is too weak, photosynthetic product accumulation is low, tillering is few and weak, yield is low, and premature aging is likely. But if light is too strong and temperature too high, there is more fiber and poor quality.

3. Water: The suitable relative air humidity for garlic chives is 60-70%, and the soil moisture is 80-90% of the maximum field water-holding capacity.

4. Soil: Garlic chives have strong adaptability to soil texture, with a suitable pH of 5.5-6.5, a high fertilizer requirement, and strong fertilizer tolerance.
