Tatsoi Growing Tips


Apply a rich compost or nitrogen rich fertiliser to the soil prior to planting. You can apply a natural liquid fertiliser such as fish emulsion every month for the best results.


Remove damaged foliage from the plant as they appear. Leaves can still be harvested as you need them. However, the mustard flavour of tatsoi descends into bitterness as the plant reaches flowering. 


Water regularly, keeping soil moist but not waterlogged. Try to avoid watering the leaves as best you can, but this is not always possible. Mulch around your plants to keep the soil wet and save water.

Pests and Diseases when Growing Tatsoi

Mildew and fungus can be a problem. One tip is to space your plants far enough apart so they are not touching each other and to allow air flow between plants.

Common pests include slugs, cabbage worms, and flea beetles. Remove these bugs when you see them and if you need to, spray regularly with white oil.

Regular application of ‘white oil’ can help address these pests. White oil is an effective organic pesticide that you can make at home.
