What is Napa Cabbage?
Napa cabbage, often referred to as Chinese cabbage, or “wong nga bok” in Cantonese, is a type of cabbage that features large, pale green heads and a delightful mild flavor. It is known as dàbáicài in Mandarin, translating to “big white vegetable,” and is different from xiǎo báicài (small white vegetable).
Napa cabbage belongs to the brassica family alongside broccoli, mustards, and kale, and is often recognized for its crisp texture and refreshing taste due to its high water content.
Here are some varieties of napa cabbage:
- Minuet: A compact variety yielding petite 9-inch heads weighing 2-3 pounds at maturity. It’s known for its slow-bolting nature and resistance to downy mildew.
- Scarlette: Sporting purple leaves resembling radicchio, this standard-sized variety weighs around 4-6 pounds, offering a visually stunning addition to dishes.
- Rubicon: This standard-sized napa cabbage, averaging 5-7 pounds, is perfect for crafting kimchi and various culinary creations.
- Blues: Bred for its slow-bolting traits and disease resistance, this standard-sized napa cabbage, weighing approximately 4-6 pounds, ensures a reliable harvest.
Creating Ideal Growing Conditions for Napa Cabbage
Napa cabbage flourishes in both spring and fall seasons, provided it’s planted early to avoid extreme summer heat. For spring planting, wait until after the frost danger has passed. Napa cabbage plants prefer temperatures between 50-80°F but struggle in excessive heat above 80-85°F.
Late summer and fall are optimal for growth due to decreasing day length and cooler temperatures, enhancing sweetness as cold prompts sugar production. However, maturity is crucial for frost survival, as young plants may suffer from leaf-end damage under severe frost conditions.
Here are some more recommendations:
- Sunlight: Napa cabbage adapts well to both full and partial sunlight but thrives with at least 6 hours of direct sunlight daily, especially during early growth stages. In warmer regions, a balance of partial sun and shade is beneficial, while cooler climates benefit from increased sunlight exposure.
- Soil Conditions: These plants also prefer fertile, well-drained, and moisture-retentive soil. Enrich the soil with a 1- to 3-inch layer of compost for essential nutrients.
- Watering: Maintain consistent soil moisture without waterlogging. Deep watering at less frequent intervals is preferred over shallow daily watering. Before any levels of anticipated heat, ensure plants receive sufficient water to withstand adverse conditions.
- Spacing: Plant spacing varies by variety, with mini varieties like Minuet requiring approximately 12 inches apart and standard varieties like Rubicon, Blues, and Scarlette needing about 18 inches between plants.
- Days to Maturity: Napa cabbage typically matures within 50-80 days, influenced by the specific variety and environmental conditions.
Some Tips for Starting Napa Cabbage Seeds Indoors
Take note of the following:
- Place only one Napa cabbage seed per cell to ensure proper growth.
- Keep the seed starting mix consistently moist, as Napa cabbage prefers cooler conditions and does not require a heating mat.
- Once the first green sprouts emerge, position the tray under grow lights. It’s important to keep the lights low to prevent leggy seedlings.
- If multiple seeds were accidentally planted in a single cell, thin out the seedlings to leave only one cabbage seedling per cell.
- Monitor the growth of the seedlings closely. When they have developed four or five leaves, it’s time to provide them with more space to grow.
- Ideally, transplant the seedlings into your garden space once the soil is workable. If not, consider potting them up into 4-inch pots to ensure they have enough room for their roots to grow.
Note: Once your seeds have sprouted four or five leaves, it’s time to grant them more room to thrive in your garden. You can transfer them to 4-inch pots if your outdoor conditions aren’t favorable yet.
Harvesting
It’s time to harvest your Napa cabbage plants 10 to 25 days after the final frost. Kindly note that you do not want to miss this harvest window. Once temperatures climb into the 70s and 80s, your Napa cabbage plants will begin to bolt, or go to seed. This alters the taste of the leaves and attracts pesky slugs, which can ruin your hard work.
When harvesting your Napa cabbage heads, use a sharp knife to cut them right at the base. Then, make room for new warm-season crops by planting them around the harvested area.
Remember, your cabbage growing season ends once you fully transition to the warm season.
Cooking Tips
One option is to sauté sliced Napa cabbage with onion, garlic, and ginger. You can then season it with soy sauce, rice vinegar, and toasted sesame oil. Alternatively, you can sear Napa cabbage in a hot pan until it is charred and then top it with miso butter.
Another delicious option is to grill Napa cabbage wedges seasoned with olive oil, salt, and pepper until they become tender and lightly charred. After that, finish them with a dressing made of fresh garlic and lemon juice.
Some chefs also like stir-frying Napa cabbage with bacon and shiitake mushrooms and then seasoning with soy sauce and black pepper. Whatever you choose to do with your Napa cabbage, what is certain is that you will always find practical recipes to experiment with online.
