30 days. This japanese mustard green has dandelion-like jagged edged green leaves with a mild, sweet, earthy flavor. Mizuna grows fast and makes an excellent salad green. It can be harvested a few outside leaves at a time, or cut the whole head near ground. It is also used in stir-fry and soups. Also wonderful as a microgreen. *** ()*** 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. NOTE: ALL GROWING INFO AND INSTRUCTIONS ARE ON ITEM PAGE. 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.
