Chives are a delightful perennial herb known for their slender, green stalks and mild onion flavor. Easy to grow and maintain, chives can thrive in a variety of conditions, making them a favorite among home gardeners. In this guide, you will learn everything you need to know about growing chives, from starting seeds to culinary uses.

Common Varieties of Chives

Here are three common varieties of chives:

Common Chives

The most popular variety features slender green stalks and beautiful purple flowers. It has a mild onion flavour, ideal for various dishes.

Garlic Chives

This variety has flat leaves and a garlic flavour, making it perfect for those who enjoy a stronger taste. Garlic chives also produce white flowers, adding visual interest to gardens.

Chinese Chives

Also known as “leek chives,” Chinese chives have thicker, hollow stems and a more robust flavour than common chives. They produce flat, wide leaves and delicate white flowers.

Seed Starting Indoors

For gardeners in colder climates, starting chives indoors is a great way to ensure an early harvest. Sow seeds 6 to 8 weeks before the last expected frost date. Here’s how to do it:

1. Choose Containers: Use seed trays or small pots with drainage holes.
2. Soil Mix: Fill with a seed-starting mix that drains well.
3. Sow Seeds: Plant seeds about 1/4 inch deep and lightly cover them with soil.
4. Moisture: Keep the soil consistently moist but not soggy. Use a spray bottle to mist the soil.
5. Light: Place the containers in a bright location, or under grow lights for 12-16 hours a day.
6. Transplanting: Once the seedlings are about 4 inches tall and have several sets of true leaves, transplant them outside after hardening them off for a week.

How to Propagate Chives Successfully

Chives can be propagated by division, making it easy to expand your garden or share with friends. Here’s how:

1. Timing: Divide chives every 2-3 years in the spring or fall when the plants are actively growing.
2. Method: Carefully dig up the clumps of chives, and use a sharp spade to separate the plants. Each division should have a healthy root system and several green shoots.
3. Replanting: Replant the divisions in well-draining soil, spacing them about 6-8 inches apart to allow for growth.

Light Requirements

Chives thrive in full sun to partial shade. Aim for at least 6 hours of sunlight each day to encourage healthy growth. In particularly hot climates, some afternoon shade can help prevent wilting.

Soil Requirements

Chives prefer well-draining, fertile soil with a pH of 6.0 to 7.0. Incorporating organic matter such as compost can improve soil quality and provide essential nutrients.

Planting Depth and Spacing

• Depth: When planting seeds, sow them about 1/4 inch deep. If transplanting, ensure the plants are set at the same depth as they were in their original containers.
• Spacing: Space chive plants 6-12 inches apart. This allows adequate airflow and reduces the risk of disease.

Watering

Chives prefer consistently moist soil. Water regularly, especially during dry spells, ensuring the soil is well-drained. Avoid overwatering, which can lead to root rot. Check the top inch of soil—if it’s dry, it’s time to water.

Boosting Chive Growth with Proper Fertilization

While chives are not heavy feeders, applying a balanced organic fertilizer in early spring can support robust growth. If you notice slow growth or yellowing leaves, consider light feeding during the growing season.

Pests and Diseases: Keeping Your Chives Healthy

Chives are generally hardy and resilient, but like all plants, they can occasionally attract pests or fall victim to diseases. By learning to identify and manage these challenges, you can ensure your chives remain healthy and productive.

Common Pests and How to Manage Them

1. Aphids
   Aphids are tiny, soft-bodied insects that feed on the sap of chives, causing curling leaves, stunted growth, and a sticky residue (honeydew) that can attract mold.
   What to Do:
   • Inspect plants regularly, especially the undersides of leaves where aphids like to hide.
   • Spray infested areas with insecticidal soap or neem oil, repeating as necessary.
   • Encourage natural predators like ladybugs and lacewings to visit your garden by planting flowers nearby.
2. Onion Flies
   These pests lay their eggs near the base of chive plants. Once hatched, the larvae burrow into the roots, damaging the plant and hindering its growth.
   What to Do:
   • Cover your chives with fine mesh row covers during the growing season to prevent flies from laying eggs.
   • Practice crop rotation by planting chives in a different location each year to disrupt the fly’s life cycle.
   • Remove and destroy any heavily infested plants to prevent the spread of larvae.

Common Diseases and Prevention Tips

1. Fungal Diseases (e.g., Downy Mildew)
   Downy mildew can cause yellowish spots on leaves, a grayish coating on the undersides, and reduced plant vigor. It thrives in damp, overcrowded conditions.
   What to Do:
   • Space chive plants appropriately to ensure good airflow. Proper spacing reduces humidity levels around the plants, which fungi love.
   • Water plants at the base to keep the foliage dry, especially in the evening. Overhead watering encourages fungal growth.
   • If you notice infected leaves, remove them immediately and dispose of them away from your garden to prevent further spread.

Organic Control Methods

For pest and disease control, consider using organic insecticides or homemade remedies. Regularly inspect your plants for signs of trouble and take immediate action.

Top Mistakes to Avoid When Growing Chives

New chive gardeners often make these common mistakes:

• Overwatering: Chives prefer moist soil but do not tolerate soggy conditions. Ensure proper drainage to prevent root rot.
• Neglecting to Thin Plants: If seedlings are too crowded, thin them out to allow proper growth and air circulation.
• Not Harvesting Regularly: Regular harvesting encourages bushy growth and prevents plants from becoming too leggy.

Harvesting Techniques

You can start harvesting chives once they reach about 6 inches in height. Here are some tips for effective harvesting:

• How Much to Harvest: Use scissors or sharp shears to cut the green stalks, ensuring you do not remove more than one-third of the plant at a time. This practice allows for continuous regrowth.
• Timing: The best time to harvest chives is in the morning when their flavour is most pronounced.

Culinary Uses

Chives enhance the flavour of many dishes and can be used in various ways:

• Garnishes: Sprinkle fresh chives on soups, salads, or omelets for a burst of flavor and color.
• Dressings and Sauces: Incorporate chopped chives into vinaigrettes, dips, or cream sauces to add a mild onion flavor.
• Dishes: Chives pair well with potatoes, fish, and eggs, complementing their flavors beautifully.

Growing Challenges

While chives are generally easy to grow, there are some challenges to be aware of:

• Humidity Effects: High humidity can lead to fungal diseases. Ensure good air circulation around your plants.
• Poor Growth: If chives are not thriving, check for signs of pests or diseases, and evaluate whether they are getting enough sunlight and water.

Frequently Asked Questions
