If you're a fan of cabbage but want something even better, Sensopai is your new garden favorite. Think of sensopai as a "loose leaf" cabbage, meaning it does not form a tight head of cabbage. Instead its leaves are harvested as needed because they have a cabbage like texture and flavor. Sensopai is a unique hybrid between Komatsuna (a Japanese mustard green) and regular cabbage, prized for its tender leaves and rich, savory cabbage flavor—often described as the best among all cabbage-type vegetables. This versatile leafy green is perfect for stir-fries, soups, and steaming, and it’s packed with nutrients. It’s easy to grow in most climates, thriving in full sun with moist, well-drained soil. Sensopai grows well in both in ground gardens, raised beds, or containers. 

I have not experienced much pest issues if grown during the correct time of year which is fall through spring. Sometimes I get cabbage worms which will munch on the leaves. I use BT or Spinosad to treat for the worms. If I grow these closer to late spring, I get some aphid issues. I have found that if I plant kale and nasturtiums all over my garden, the aphids will feast on them instead. Therefore, I use kale and nasturtiums as a trap crops. I have a Trap Crop seed collection if you want to grow more of the trap crops that I recommend and use in my garden. 

Seed Sowing Depth: 1/4” deep, barely press the seeds into the surface of the soil

Sowing: Direct sow seeds right after your last spring frost date. Or direct sow seeds when you plant your fall garden. You can also grow transplants indoors, 8 weeks before your last average spring frost date. Use larger sized containers, like a 4 inch pot or solo cups with drainage holes cut out of the bottom. 

Ideal Growing Conditions

Sun: Full sun. In hot climates, plant in a spot that gets full morning sun with afternoon shade. 

Water: Keep the soil consistently moist

Fertilizer: Mix some blood meal into the soil before direct sowing seeds. Continue to fertilize with something high in nitrogen every 3 to 4 weeks. 

When & How To Sow Seeds: For a spring crop: General guidelines say to sow seeds indoors, 6 weeks before your last spring frost date. Can also direct sow the seeds after your last spring frost date. For a fall or winter crop or for hot climate gardeners: direct sow seeds starting at 3 months from first winter frost, and continue into the winter months if you can protect plants from hard freezes (when temperatures drop below 28F). Sprinkle a few seeds so there are 4 per square foot. Cover with ¼ inch of soil and gently water them in. Thin out any extra seedlings that germinate to leave 4 total plants per square foot.

Germination: 3-10 days

Days To Maturity: 40 days after direct sowing the seed

How & When To Harvest: Sensopai will not form a head of cabbage like regular cabbage. Instead harvest the leaves as needed. You can start harvesting baby greens as soon as 40 days after direct sowing the seeds. 

Common Diseases: Can get clubroot like other brassicas, which causes swollen roots, wilting, and stunted growth. To manage it, rotate crops, raise soil pH with lime, remove infected plants and keep the garden clean to prevent its spread. Treat any leaf diseases (powdery mildew, spots), with 1 cup of hydrogen peroxide per gallon of water spray to clean and disinfect. Repeat every 5 days or so as a preventative, or until you notice the spread of the disease has stopped.

Common Pests: One of the most common pests when growing cabbage is the cabbage worm, which is green with white stripes down its back. Classic signs of a worm infestation include munched on leaves and finding little green, black, or orange balls which is the frass (poop) of these worms. You can hand pick them off your plants, but if the infestation is severe, spray with an organic worm treatment like Bacillus thuringiensis (Bt). 

Do I have a YouTube video tutorial on how to grow this? I have a review video that shows sensopai growing in my garden, explains what it is, and how to use it.
