SCIENTIFIC NAME: Brassica rapa var. narinosa
This growing information is for baby-leaf production of the following Brassicas, including baby mustard greens, mizuna, tatsoi, and komatsuna: Brassica carinata, B. juncea, B. napus (‘Red Russian’), B. oleracea, B. rapa, B. rapa var. chinensis, B. rapa var. japonica, B. rapa var. narinosa, B. rapa var. perviridis
CULTURE: Brassicas prefer soil with a pH of 6–7.5 and can be grown all season in the field. Most varieties are hardy enough to grow in cool greenhouses and high tunnels during winter from late summer and early autumn sowings
DAYS TO MATURITY: From emergence after direct seeding
DIRECT SEEDING: Sow 6mm deep at 3–5 seeds/25mm, in rows at least 25mm apart from early spring into midsummer. Can be sown into late autumn if overwintering in a high tunnel or other protected structure
SUCCESSION PLANTING: For a continuous supply, sow about every 2 weeks
DISEASES & PESTS: Control flea beetles by applying fabric row cover at time of sowing and/or applying insecticides such as azadirachtin or pyrethrin. Cabbage worms and loopers can be controlled with Bacillus thuringiensis (Bt). Prevent disease with crop rotation and sanitation
HARVEST: Harvest with a knife when leaves reach desired size, about 7-15cm. Make sure to cut above the basal plate for cut-and-come-again harvests. Cut again when plants are at desired size, 5–14 days depending on variety and season
AVG. SEEDING RATE: For Mizuna, Tatsoi, Komatsuna, and Pac Choi: 30g/70m, 500g/1km. For Kale: 1,000 seeds/5.5m, 30g/40m, 500g/600m. For Mustard: 30g/85m, 500g/1.25km
SEED SPECS: Mustard: Avg. 17,000/30g; Mizuna, Tatsoi, Komatsuna: Avg. 13,300/30g; Pac Choi: Avg. 11,000/30g; Kale: Avg. 8,200/30g
SIZED SEEDS: Kale seeds are sized except where noted
PACKET: 250 seeds, sows 1.3m. For Kale: 100 seeds, sows 45cm
