Growing Choy Sum Indoors: Your Winter Gardening Hero

Don’t let cold weather stop you from growing fresh greens! Choy Sum thrives in containers, making it an ideal choice for indoor gardeners. Here’s how to grow it indoors like a pro:

1. Pick the Right Pot
   You don’t need anything fancy—a simple container that’s at least 6-8 inches deep will do. Just make sure it has drainage holes. No one likes soggy roots!
   
   
2. Set the Stage with Great Soil
   Fill your pot with a high-quality potting mix. Bonus points if it’s enriched with compost or slow-release fertilizer. Happy soil means happy plants.
   
   
3. Find the Light
   Place your container in the sunniest spot you’ve got, like a south-facing window. If sunlight is limited, grab a grow light to keep your Choy Sum basking in "daylight" for 12-14 hours a day.
   
   
4. Stay Hydrated
   Keep the soil evenly moist but not waterlogged. Check it regularly—if the top inch feels dry, it’s time for a drink.
   
   
5. Harvest Like a Gardener Extraordinaire
   Once your Choy Sum plants are about 6-8 inches tall, start snipping the outer leaves. This encourages the plant to keep growing so you can enjoy multiple harvests.

 

Can Choy Sum Grow Outdoors Too?

Absolutely! If the weather’s cool (50°F to 75°F), Choy Sum will thrive in your garden bed. Here are a few quick tips:

• Planting: Sow seeds ¼ inch deep in rows, spacing plants about 6 inches apart. Thin them out as needed.
• Sun and Soil: Pick a sunny spot with well-draining, loamy soil. Add compost to give your plants a boost.
• Watering: Water regularly, keeping the soil moist but not soaked.
• Pests: Keep an eye out for aphids or flea beetles. A sprinkle of neem oil can work wonders.

 

How to Use Choy Sum in the Kitchen

Now for the fun part—eating! Choy Sum's mild, sweet flavor makes it a superstar in the kitchen. Here are a few ideas to get you started:

• Sizzle It Up: Toss it in a hot pan with garlic, soy sauce, and a drizzle of sesame oil for a quick stir-fry.
• Soup It: Add it to your favorite broth for an instant upgrade.
