Bermeo Cauliflower - Organic

seeds
Brassica oleracea (botrytis group)
(65 days) F-1 hybrid. The seaport town of Bermeo in the Basque region of Spain sees intolerable summer heat, weather that is kryptonite to cauliflower. Even in Maine, the idea of cauliflower in hot humid July is laughable. For kicks, we did a summer trial of the supposed heat-tolerant kinds. Our curd-loving but doubtful chuckles were silenced in adoration of Bermeo—a perfect unmarred head, without warping, melting or discoloration in high summer. All others dissolved into chaos, while Bermeo endured with tasty firm curds of fall-harvest quality. Still wary, we tried Bermeo again in 2020’s epic dry hot summer—same wonderful result! Also makes excellent mid-early fall heads. Our first organic cauliflower since Cassius was dropped from the seed trade in 2012. Tested negative for BR and BL. White or yellow certified-organic coating. ④

Additional Information

Cauliflower

  • About 100–300 seeds/g.
  • Days to maturity are from transplant date.

Culture: Cauliflower heads will “button” under stress. Do not allow seedlings to get pot-bound; avoid interruptions in growth. Most varieties can’t stand the heat and are not suitable for summer production. When heads first appear, bend leaves over curd to prevent discoloring. Wire hoops and row cover should be used at early stages to keep out flea beetles and swede midge.

Minimum germination temp 40°, optimal range 55–80°.

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.

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.

  • BL: Blackleg
  • BR: Black Rot
  • BS: Bacterial Speck
  • DM: Downy Mildew
  • FW: Fusarium Wilt

Material controls: AzaMax, 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 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 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.
