To plant and maintain Chinese chives (also known as garlic chives), choose a sunny location with well-drained soil, amend with compost, and plant seeds or seedlings 4-6 inches apart, watering consistently, especially during establishment. Once established, harvest leaves regularly by cutting them close to the ground, and consider dividing clumps every few years for optimal growth.
Planting:
Timing: Sow seeds in spring as soon as the soil warms up, or start seeds indoors 6-8 weeks before the last frost.
Location: Choose a sunny location (6-8 hours of sunlight is ideal) with well-drained soil.
Soil: Amend soil with compost to improve drainage and fertility.
Spacing: Sow seeds 1/4 inch deep, 4-6 inches apart, or transplant seedlings 6-8 inches apart.
Watering: Water thoroughly after planting and keep the soil consistently moist, especially during establishment.
Containers: Chinese chives also grow well in containers, ensuring good drainage.
Maintenance:
Watering:
Provide consistent moisture, but avoid overwatering, as chives are sensitive to wet soil.
Fertilizing:
Apply a balanced fertilizer in early spring or early summer if your soil is not rich in nutrients.
Weeding:
Keep the area around the chives weed-free, as weeds can compete for resources.
Harvesting:
Harvest leaves by cutting them close to the ground as needed, encouraging new growth.
Dividing:
Divide clumps every 3-4 years in the spring to maintain vigor and prevent overcrowding.
Pest and Disease:
Chives are generally pest and disease-resistant, but watch for root rot in poorly drained soil.
Flowers:
You can cut back the flowers to prevent seed production or leave them to attract pollinators and add visual interest.
Chinese chives are a perennial vegetable that, once planted, can be harvested for many years. They grow rapidly and can be cut approximately every 20 days.
The number of chive harvests per year depends on their growth rate, typically ranging from 5 to 7 times annually. Harvesting is mainly done in spring and autumn, while during summer and winter, plants are preserved for growth.
Spring: Due to vigorous growth and high quality, chives can be harvested 3-4 times.
Autumn: As temperatures drop, chives can be harvested 2-3 times, but if you plan to harvest chive sprouts (韭黄) in winter, it’s advisable to reduce autumn harvests.
It is best to replant chives every two years. Although chives can be harvested for up to ten years, only the first two years provide high yields. Over time, the plant’s roots age, the density increases, and the soil loses essential micronutrients, leading to reduced productivity. Replanting every two years helps maintain healthy yields.
Avoid harvesting in the first year to promote strong root development. Premature harvesting affects future yields.
Do not cut too close to the ground, as it may hinder regrowth and increase disease risk. Leave about 1 inch of stem, cutting at the leaf sheath to avoid damaging the bulbs.
Maintain proper intervals between harvests—once chives grow to 8-10 inches with 7 leaves and 1 heart, they can be cut. In spring and autumn, allow 20-25 days between harvests:
Spring: 3-4 harvests
Autumn: 2-3 harvests
After harvesting, apply wood ash to prevent chive maggots and supplement potassium and calcium.
If growth is weak due to insufficient water and nutrients, extend the interval between harvests to allow the plants to recover.
