Brassica rapa (japonica group)
(40 days) Open pollinated.

Recommended for northland salad enthusiasts, this vigorous heirloom Japanese mustard produces slender white stalks with deeply cut and fringed dark green leaves, not at all pungent. One planting could suffice for full-season production if watered in dry spells and kept cut, though a few will bolt in September. Many folks will prefer to make three or more succession plantings because the young leaves are the most tender. Biennial. Essential in mild mesclun and great for microgreens. Tested negative for BR and BL.

Additional Information

Asian Greens

Days to maturity are from emergence after sowing; from transplant, subtract 20 days.

Culture: Wire hoops and row cover keep out flea beetles and are a must for pristine salad or braising mixes!

Diseases:

ALTS: Alternaria Leaf Spot
BL: Black Leg
Black Rot
BSR: Bacterial Soft Rot
DM: Downy Mildew

Major pests: Cabbage Looper, Diamondback Moth, Imported Cabbageworm
Cultural controls: control cabbage-family weeds near crop fields, till under crop debris of early-season brassicas after harvest.
Material controls: Spinosad, Bt.

Pest: Flea Beetle
Cultural controls: floating row covers, mulch with straw, time plantings for fall harvested crops only, crop rotation, perimeter trap cropping.
Material controls: Spinosad, Pyganic.

Pest: Cabbage Root Maggot
Cultural controls: time planting to avoid first hatching, use row covers, control weeds.

Major diseases: Black Rot, Alternaria Leaf Spot, Blackleg, Club Root, Downy Milldew, White Mold
Cultural controls: avoid transplanting plants with yellow leaves or v-shaped lesions, crop rotation, destroy crop debris after harvest, avoid overhead irrigation, control weeds, allow for good air movement.
Material controls: Copper.

Note: because of a rule issued by Oregon, we cannot ship brassica packets larger than ½ oz. (14 grams) into the Willamette Valley, except those that have tested negative for Black Leg and Black Rot. Check descriptions for information.

Mustards

About 8,750-22,000 seeds per oz, with wide variability among varieties.

Versatile for tasty microgreens. Mustards are potent soil fumigants. Incorporating the residues of mustard crops into your soil can reduce fungal diseases in your succession crop. See Mustard from Organic Growers Supply for a cover crop, and Yellow (White) Mustard for culinary mustard.

Saving Seed: Saving mustard green seed is easy! Let your spring sowing of mustards bolt. The flowers develop into narrow seed pods. Once pods dry on the stems, they can be easily broken open for seed. To ensure true-to-type seed, grow only one open-pollinated variety per season (or let only one flower!)

Brassicas

Days to maturity are from transplant date.

Culture: Start brassicas indoors March-May for setting out May-July, or direct-seed in May, or in June for fall crop. Minimum germination soil temperature 40°, optimal range 55–85°. Easier grown for the fall because many varieties perform poorly in hot summers. For better stands in dry conditions, sow in trenches and keep irrigated. Wire hoops and row cover should be used at early stages to keep out flea beetles and swede midge.

Diseases:

BL: Blackleg
BR: Black Rot
BS: Bacterial Speck
DM: Downy Mildew
FW: Fusarium Wilt
FY: Fusarium Yellows
TB: Tipburn
WR: White Rust

Pest and Disease Remedies for all Brassicas

Pest: Cabbage Root Maggot
Cultural controls: time planting to avoid first hatching, use row covers, control weeds.

Major diseases: Black Rot, Alternaria Leaf Spot, Blackleg, Club Root, Downy Mildew, White Mold
Cultural controls: avoid transplanting plants with yellow leaves or v-shaped lesions, crop rotation, destroy crop debris after harvest, avoid overhead irrigation, control weeds, allow for good air movement.
Material controls: Copper.

Disease: Head Rot
Cultural controls: use well-domed varieties, harvest heads when tight, cut stalks at an angle.
Material control: Copper.

Swede Midge—not as cute as it sounds!

Alert! Heading brassicas in the Northeast are seeing consistent damage from swede midge, a tiny gall midge. Its effects result in a non-heading plant. Wire hoops and row cover at early stages of heading brassica crops are becoming crucial for success. Some research also suggests garlic sprays as a possible organic repellent. Consult your Cooperative Extension resources for further information.
