Tatsoi Mustard is known my many names, including tat soy, tat soi, spoon mustard, spinach mustard, broad beak mustard, rosette bok choy, and even Chinese cabbage.

It is quick growing and one of the milder mustards.

Tatsoi is a quick growing microgreen and grows well in northern climates, often over wintering in zone 5 and higher.

How Much Seed Do You Need For Your Tray?

You don’t need to worry about how much seed you need if you use Home Microgreen planting trays or 1010 trays. Each seed packet has the correct number of seeds for a perfect tray of organic Wasabina Mustard microgreens.

The seeding area of a Home Microgreen Tray is 37.5 square inches.

However, if you’re using a different planting tray, use the calculator in the article below to figure out how much seed you need.

Seeding Density

Seeding Density for Tatsoi Mustard Seed

By Weight

Home Microgreens Tray: 2.0 grams

1010 Tray: 5.3 grams

1020 Tray: 10.6 grams

By Measuring Spoon

Home Microgreens Tray: 0.6 teaspoons

1010 Tray: 1.5 teaspoons

1020 Tray: 3.1 teaspoons

All volumetric measurements are level, not heaping spoons.

I use these vertical-sided measuring spoons because the seeds are easier to level with the straight sides.

These are my recommended seeding densities to produce a great-looking tray of Tatsoi Mustard microgreens.

I like to allow microgreen leaves to develop to a larger size as they provide more nutrition & flavor than producing smaller leaves and stems.

Microgreen density depends on many environmental factors and seed germination percentages.

You may prefer to modify the seeding density, but my seeding densities are a great starting point, if nothing else.

Check out the Home Microgreens Seed Density Course if you have a different size tray.
