NOTE: The terms Tatsoi and Brassica rapasubsp. narinosa are identical in this text; in reality, Brassica rapasubsp. narinosa is Tatsoi’s biological word.
Most Asian greens are easy to grow in a vegetable garden. A non-heading mustard that is very similar in flavor to bok choi is called tatsoi. bok choi has long, spoon-shaped leaves, while tatsoi plants tend to grow in a flatter rosette. They can be sold as loose-leaf or as bunched together.
If you would like to try your hand at growing tatsoi, you will be happy to know that it is undemanding. As with most Asian greens, it grows quickly and has few problems.

Why are my Tatsoi leaves turning yellow?
In the world of horticulture, yellowing leaves are undoubtedly the most common problem. The two main causes of this problem are overwatering and a lack of nutrition.
Reduce your watering frequency when you fear your plants are being overwatered, and follow these steps to determine whether they may be lacking in nutrients:
Each deficiency produces a different yellowing on the Brassica rapasubsp. narinosa in question, here’s how to spot them:
- The first symptom of a magnesium deficiency is yellow patches between leaf veins on elder leaves. The leaf’s core turns yellow while the veins stay green. The edges of the leaf yellow last.
- Yellowing between leaf veins is another sign of iron shortage, but young leaves on plant tops and branch tips are initially affected.
- Sulfur shortage first affects the youngest leaves, turning them entirely yellow.
- Insufficient potassium causes the leaf edges to turn brilliant yellow while the interior of the leaf stays green. Older leaves show the symptoms initially, and the leaf edges quickly darken.
- A lack of nitrogen is indicated by a widespread yellowing. Older, inner leaves are the first to yellow. As the yellowing progresses, it eventually touches young leaves as well.
Our Solution
You only need to respond to the signs mentioned above. A gardening store expert will be able to provide you advice on how to purchase a specific soil to treat a potassium or nitrogen deficiency. Additionally, you can reduce how often you water your plants.
Is my Tatsoi sunburned?
It is quite easy to find out if your Tatsoi (Brassica rapasubsp. narinosa) has been burned by the sun. Just like on us, your plant will change color in this case, it will start to turn yellow or white.
The leaves of your Tatsoi can also change color in case it gets too much water or not enough light, as we saw above.
To find out if the yellow leaves have been sunburned, look at the part of the bottom that is tinted closer to the base. The yellow leaf is probably burnt and not something else if this portion stays greener.
Why are my Tatsoi leaves turning brown?
Most of the time, leaves of a Tatsoi that turn brown is a sign that your plant has been sunburned, it has probably been exposed to too much direct sunlight. Don’t panic, your plant probably won’t die from this, but its growth will take a hit.
Should I leave my Brassica rapasubsp. narinosa in direct sunlight?
No! If your Brassica rapasubsp. narinosa (or Tatsoi) has the symptoms described above, don’t leave it in direct sunlight, that’s the reason why your Tatsoi is in such a state!
Our Solution
As explained in the paragraph above, the solution is simple, just place your Tatsoi in a place where the light does not reach it directly, in this way and with a correct watering, your plant should resume its life rather quickly.
Why are my Brassica rapasubsp. narinosa leaves drooping or wilting ?
This typically occurs when your Brassica rapasubsp. narinosa gets dehydrated. Large plants are more at risk since they naturally require more water than smaller plants.
You may quickly determine if your Brassica rapasubsp. narinosa plant needs water by under-weighing its pot; if it seems light, the soil and roots are probably fairly dry and require water.
Our Solution
If the soil in your plant’s pot is completely dry, you will need to start by moistening it so that the roots will also benefit from the water. A common mistake is to drown the Tatsoi right after a dry period thinking that it needs a lot of water.
This is true, but the easiest way to end it is to give too much water at once. Instead, you should water the soil properly, returning to a peaceful watering rhythm.
Caring Tips for Brassica rapasubsp. narinosa
Water Occasionally
Water is essential to the survival of your plant, however, it is important to balance the rate of watering. As we explained above, overwatering could have fatal consequences for your Brassica rapasubsp. narinosa.
You can tell if your plant needs water by touching the soil; if it still feels damp, it’s usually preferable to wait a few more days.
Always keep temperatures stable
It’s also a good idea to keep your Brassica rapasubsp. narinosa at a constant temperature, especially if it’s kept indoors. In general, at GreenShack, we suggest booking a temperature between 65 and 85 degrees F. Of course, keep your Brassica rapasubsp. narinosa away from radiators, air conditioners, and other sources of hot or cold air.
Keep your Tatsoi Dust-Free
This one is about houseplants. Your indoor plants’ leaves get dusty just like your furniture does. The problem is that this might prevent photosynthesis from beginning, which would result in the plants gradually losing their color.
This would also make the pests happy, a real descent into hell for your Tatsoi.
Take a microfiber cloth and gently massage the plant’s leaves to get rid of the dust. Use a damp cloth to make dust removal easier, but avoid using corrosive materials like rubbing alcohol!
Keep drainage in mind
If you tend to overwater, you need to pay attention to your drainage, and we advise choosing a saucer and a pot with drainage holes if they are not already there.
If your pots don’t already have holes in them, you can add volcanic rocks (or any other pebbles with holes) to the bottom of your pot in the meantime. This will assist in creating a channel and keep the water from pooling there for an extended period of time, protecting the roots from decay.
