Growing Choi Sum: Your DIY Guide for a Bountiful Harvest

Hello garden friends! I’m thrilled to show you today how you can easily grow your own Choi Sum, also known as Chinese flowering cabbage. Choi Sum is not only super delicious but also rich in vitamins and minerals. And the best part: it’s really uncomplicated to grow, even if you’re a gardening beginner. So, let’s roll up our sleeves and get started!

What You Need for Growing Choi Sum
Before we begin, here is a list of everything you’ll need:

• Choi Sum seeds: Preferably organic seeds to ensure you get healthy and tasty plants.
• Seed starting mix: For starting indoors or in a greenhouse.
• Pots or seed trays: For starting seeds.
• Garden soil: Good, nutrient-rich soil for the garden bed or container.
• Compost or organic fertilizer: to enrich the soil.
• Watering can or garden hose: For regular watering.
• Garden tools: Spade, rake, trowel.
• Slug bait (optional): If you live in an area with many snails.
• Fleece/Row cover (optional): To protect against pests and frost.

Preparation: Laying the Foundation for a Successful Harvest
Proper preparation is the key to successful Choi Sum cultivation. Here I’ll show you how to prepare everything optimally:

1. Choose the right time: Choi Sum is a cool-weather vegetable. The best time for sowing is in the spring (March to May) or late summer (August to September). This way, you avoid the plants bolting (flowering quickly) in high temperatures.
2. Select the location: Choi Sum loves the sun, but partial shade is also fine. It is important that the location is well-ventilated and the soil is loose and rich in humus.
3. Prepare the soil: Loosen the soil thoroughly and remove weeds and stones. Mix compost or organic fertilizer into the soil to enrich it with nutrients. Choi Sum is a heavy feeder and needs sufficient nutrients for healthy growth.

Sowing: Getting the Seeds into the Ground
There are two ways to grow Choi Sum: either sow directly into the bed or start the seeds indoors. I personally prefer starting them indoors, as I can better control the plants and protect them from pests.

Sowing Indoors or in a Greenhouse (Starting Indoors)

1. Prepare seed trays: Fill the seed trays or pots with seed starting mix. Press the soil down lightly.
2. Sow seeds: Distribute the Choi Sum seeds evenly over the soil. Cover the seeds with a thin layer of soil (approx. 0.5 cm).
3. Watering: Moisten the soil gently with a spray bottle or watering can. Make sure the soil does not get too wet.
4. Keep warm: Place the seed trays in a warm and bright place. The ideal germination temperature is 15-20°C.
5. Keep moist: Keep the soil evenly moist, but not wet.
6. Pricking out: As soon as the seedlings have developed their first true leaves (after about 2-3 weeks), you can prick them out. This means you carefully take the small plants out of the seed trays and transplant them into larger pots. Be careful not to damage the roots.

Direct Sowing into the Bed

1. Make furrows: Make furrows in the prepared soil with a rake or a stick. The furrows should be about 1-2 cm deep and about 20-30 cm apart.
2. Sow seeds: Distribute the Choi Sum seeds evenly in the furrows.
3. Cover: Cover the seeds with a thin layer of soil.
4. Water: Moisten the soil gently with a watering can.
5. Thinning: As soon as the seedlings have emerged and developed a few leaves, you should thin them. This means you remove the plants that are too close together so that the remaining plants have enough space to grow. The distance between the plants should be about 15-20 cm.

Care: Ensuring Healthy and Strong Plants
Choi Sum is relatively low-maintenance, but there are a few things you should keep in mind for your plants to thrive:

1. Watering: Choi Sum needs regular water, especially during dry periods. Make sure the soil is always slightly moist, but avoid waterlogging. It’s best to water in the morning or evening to avoid evaporation.
2. Fertilizing: Fertilize the plants regularly with organic fertilizer or compost. Choi Sum is a heavy feeder and needs sufficient nutrients for healthy growth. I fertilize my plants every 2-3 weeks with diluted nettle tea or an organic vegetable fertilizer.
3. Weeding: Keep the bed or container free of weeds. Weeds compete with the Choi Sum plants for nutrients and water.
4. Pest control: Choi Sum can be infested by various pests, such as slugs, flea beetles, or aphids. Check the plants regularly and combat pests with natural remedies if necessary. Slug bait can help keep slugs away. A row cover protects against flea beetles and other pests. For aphid infestations, it often helps to spray the plants with a jet of water or treat them with a solution of soft soap and water.
5. Preventing bolting: Choi Sum tends to bolt quickly in high temperatures. Once the plants form flowers, the leaves become bitter. To delay flowering, you should harvest the plants regularly and provide sufficient shade.

Harvesting: Reaping the Rewards of Your Work
Choi Sum can be harvested as early as 4-6 weeks after sowing. The best time to harvest is when the stems are still tender and the leaves are juicy.

1. Harvesting: Cut the plants with a sharp knife or scissors just above the ground. You can either harvest the whole plant or just individual leaves.
2. Storage: Choi Sum does not keep for long. It’s best to process it immediately after harvesting. In the refrigerator, it will keep for about 2-3 days wrapped in a damp cloth.

Choi Sum in the Kitchen: Versatile Uses
Choi Sum is incredibly versatile and can be prepared in various ways. You can use it raw in salads, steam, fry, boil, or process it in soups and stews. Choi Sum is particularly delicious in stir-fry dishes or as a side dish with meat and fish.

Here are a few ideas on how you can use Choi Sum in the kitchen:

• Fried Choi Sum with garlic and ginger: A classic of Chinese cuisine.
• Choi Sum salad with sesame dressing: A refreshing and healthy appetizer.
• Choi Sum soup with tofu and noodles: A warming and filling meal.
• Choi Sum as a side dish to grilled fish: A light and delicious complement.

I hope this guide has helped you to grow Choi Sum successfully. With a little patience and care, you will soon be able to enjoy a bountiful harvest.

Frequently Asked Questions (FAQ)

What is the best time of year to plant Choi Sum?

Choi Sum is a cool-season crop, meaning it thrives in temperatures between 50°F and 70°F (10°C and 21°C). The best time to plant it depends on your local climate. In general, you can plant Choi Sum in early spring or late summer/early fall. For a spring crop, start seeds indoors 4-6 weeks before the last expected frost. For a fall crop, sow seeds directly into the garden in late summer or early fall, about 6-8 weeks before the first expected frost. Avoid planting during the hottest months of summer, as high temperatures can cause the plants to bolt (go to seed prematurely).

How much sunlight does Choi Sum need?

Choi Sum requires at least 6 hours of sunlight per day to grow well. Choose a location in your garden that receives full sun for most of the day. If you live in a particularly hot climate, some afternoon shade can be beneficial to prevent the plants from overheating. If you’re growing Choi Sum indoors, use grow lights to supplement natural sunlight.

What kind of soil is best for growing Choi Sum?

Choi Sum prefers well-drained, fertile soil that is rich in organic matter. Before planting, amend your soil with compost, aged manure, or other organic materials to improve its drainage, fertility, and water-holding capacity. The ideal soil pH for Choi Sum is between 6.0 and 7.5. You can test your soil pH using a soil testing kit and adjust it accordingly.

How often should I water Choi Sum?

Choi Sum needs consistent moisture to thrive. Water your plants regularly, especially during dry periods. Aim to keep the soil consistently moist but not waterlogged. Water deeply and less frequently, rather than shallowly and more often. This encourages the roots to grow deeper, making the plants more drought-tolerant. Check the soil moisture regularly by sticking your finger into the soil. If the top inch of soil feels dry, it’s time to water.

What are some common pests and diseases that affect Choi Sum?

Choi Sum can be susceptible to several pests and diseases, including aphids, cabbage worms, flea beetles, and downy mildew. To prevent pest and disease problems, practice good garden hygiene. Remove weeds and debris from around your plants, and water them at the base to avoid wetting the foliage. Inspect your plants regularly for signs of pests or diseases, and take action promptly if you spot any problems. You can use organic pest control methods, such as insecticidal soap or neem oil, to control pests. For diseases, ensure good air circulation around your plants and avoid overcrowding.

How do I harvest Choi Sum?

You can harvest Choi Sum when the flower stalks are just beginning to form, typically about 40-50 days after planting. Cut the entire plant at the base, or harvest individual leaves as needed. The leaves are most tender and flavorful when they are young and small. Regular harvesting encourages the plant to produce more leaves.

Can I eat the flowers of Choi Sum?

Yes, the flowers of Choi Sum are edible and have a slightly sweet, peppery flavor. They can be added to salads, stir-fries, or other dishes. However, once the plant starts to flower, the leaves may become more bitter.

How do I store harvested Choi Sum?

Store harvested Choi Sum in the refrigerator in a plastic bag or container. It will keep for several days. To prolong its shelf life, you can wrap the leaves in a damp paper towel before storing them.

Can I grow Choi Sum indoors?

Yes, you can grow Choi Sum indoors, especially if you have limited outdoor space. Choose a pot that is at least 12 inches deep and wide, and fill it with well-draining potting mix. Place the pot in a sunny location or under grow lights. Water regularly and fertilize every few weeks.

What are some good companion plants for Choi Sum?

Good companion plants for Choi Sum include carrots, radishes, lettuce, spinach, and onions. These plants can help deter pests, improve soil health, and provide shade for the Choi Sum plants. Avoid planting Choi Sum near brassicas like cabbage, broccoli, and cauliflower, as they can attract the same pests and diseases.
