30 days. Another great Japanese mustard, especially well suited to microgreen production. The red leaf is not a deeply divided as regular mizuna. Spicy flavor, easy to grow.

A cousin to kale and collards, mustard is a tenacious leafy green but it's not as cold-hardy. Grow in clumps about 12-18 inches apart. Use straw mulch to hold in soil moisture. Start 4-6 weeks before the first frost for a fall harvest. For a spring harvest, start seeds 4 weeks ahead of the last frost. You can harvest and allow to regrow over a period of a couple weeks as long as the weather permits. Cut leafy greens 3-4 inches from the ground and allow sufficient time to regrow.

Sowing: In early spring, plant just below the surface of the soil. This seed germinates best at temperatures from 40-55 degrees F (4-13 degrees C). Keep the soil lightly moist until germination occurs, which usually takes place within 7-10 days. This seed also germinates well in late fall for a late season crop.

Growing: Water occasionally and keep weeds down. This plant grows well in many soil types, and tolerates cold temperatures very well. It also grows well in containers.

All multiple orders of the same seed are put in the same bag. For example if you order 500 beefsteak tomato seeds x 3 then 1500 seeds will be put in the same bag. We do not send out 3 individual bags with 500 in each. This goes for all seeds unless they are listings of different seeds.


If you can’t find germinating and instructions online you can find them on the item page. Our goal is to save money everywhere we can so we can pass those savings on to you.
