The best time to plant most varieties of cauliflower is in the spring so they grow and produce their flower heads before summers hot temperatures ramp up. Other varieties are suited for mid-summer planting for a fall harvest. A good fall recommendation is its pointy, green Romanesco cousin.
Appendix trial design and weather conditions
Hot weather makes cauliflower bolt mature quickly and start to bloom which means it will stop making curds and begin making flowers and seeds. That ends its value as a food-producing plant. So as soon the temperatures warm up, cauliflower is history.
Another way to blanch cauliflower: Just put a bucket over a plant. Don't want to be bothered with blanching? Plant a colored variety of cauliflower, or a self-blanching variety that doesn't need your help to achieve its peak color.
Sow the seeds in small batches on a regular basis until the summer to give continuity of supply. If you want your cauliflower for use over winter then sow in the early summer, and choose a variety that has been bred for harvesting at the correct time. - There are Summer cropping, Autumn Cropping, and over-winter cauliflowers,and they have all beeb bred for that specific purpose. The plants prefer a heavier soil, and growing especially well in a well drained soil that holds moisture in the summer, however are prone to club-root so if you have this in the soil, select a club-root resistance variety.
Water plants well in dry weather and covers the soil with amulchto conserve soil moisture. Occasional feeds with a liquid feed through summer will improve the crop. The curds of summer cropping varieties need protection from strong, burning sunlight - simply bend a few of the larger, upper leaves over them. Doing this in late autumn and winter will protect against frost damage.
The term cole crops refers to waxy-leaved brassicas of European origin, of the species Brassica oleraceae. Cabbage, broccoli and cauliflower and other brassica crops are hardy crops that are well adapted to New England. Plants maturing under cool weather conditions are of especially high quality. This diverse family has similar cultural requirements, diseases and pests.
Cabbage is the most widely grown and easily cultivated of the cole crops. Some varietiesmature in as few as 60 days or as manyas 120 days from transplanting. The early and mid-season varieties are generally better suited for fresh market sales where small heads of 3-4 lb are desired.
Cauliflower is more difficult to grow thanother brassica crops. Common problems include failure to head properly and poor curd quality. For successful production of cauliflower, a fertile, moist soil relatively high in organic matter and nitrogen is needed. Buttoning is the premature formation of the head, whenthe leaves are not large enough to produce a head ofmarketable size. Conditions that reduce the vigor of the plant and retard vegetative growth, such as cold temperatures at transplanting and any of a number of other stresses appear to encourage buttoning. auliflower varieties range in maturity from 55 to 95 days.
Broccoli is not as exacting in its requirements as cauliflower, however, it must be harvested promptly to avoid flowering. The earliestspring plantings often experience buttoning. In summer months,temperatures over 85° F during the critical period when the head begins to form can result in poor head quality. In Southern New England, broccoli is best grown as a fall crop. roccolivarieties range in maturity from 55 to 75 days.
Early plantings of cabbage and other cole crops are generally made by setting out transplants grown in greenhouses or cold frames. Transplants should be 4-6 weeks old at field setting; and, for cauliflower and broccoli, transplants should be produced in greenhouses with a minimum temperature of 55 F. Excessive cold, transplant stress, inadequate fertility or other sources of stress in early stages can cause cole crops to button, or to go to seed without heading. Transplants with thick stems are likely to head prematurely or button. Midseason and late plantings can be transplanted or direct seeded. Hvis kål, broccoli eller blomkål er direkte podet, skal 2-3 uger tilføjes til antallet af dage til modenhed.
Brusselsspirer, der oftest dyrkes fra Transplantation S . Generelt dyrkes de som en langsæson afgrøde dyrket til efterårshøst. Cool vejr og lette frost før høst øget kvalitet. Rækker er typisk adskilt 3 'fra hinanden med 15 "afstand i rækken. Planter kan være toppet i begyndelsen af Septemberto Forbedre spire størrelse ensartethed, hvis der høstes hele stilke. Rimming løv fra den nedre 1 / 2-2 / 3 af planten vil tillade mere lyset At nå de udviklende spirer, samt øge luftcirkulationen, hvoraf begge øger spire kvalitet.
Kalecan er vokset med succes fra direkte såning eller fra Transplantation S . For Direkte såning, så frø ved 3 til 4 lb pr. Acre i rækker fordelt 16 "-36" fra hinanden. Tynd til 4 "-5" fra hinanden i rækken. Transplantationer er sat i rækker 16 "-36" fra hinanden og 6 "-12 "Bortset fra i rækken. Brug bredere mellem-række og i rækkeafstand for flere håndhøster med Stripping Blade.
Kohlrabi kan dyrkes til forårskasser med Transplantation S . Transplantation i feltet samtidig med broccoli eller kål. Fall afgrøder kan etableres ved direkte såning mellem 25. juni og 15. juli. Frøet åbent - Purolineret Varianter på ratten E på 2-3 lb per acre og tynd til 6-8 mellem planter i rækken. Præcisionsfrøhybrid sorter. Indstil Transplantation S 20. juli til 15. august. Space rækker 18-24 fra hinanden.
Blomkål. n Bestil at producere den attraktive hvide ostemasse i de fleste blomkålsorter, er det nødvendigt at blanche hovedet. Når hovedet er 2 "-3" i diameter, samles de store ydre blade løst over hovedet og binde med garn eller gummibånd. Binde hver anden til tre dage med forskellige farvede bands for at hjælpe med at koordinere høstdatoer. Varmt, fugtigt, regnigt vejr efter binde kan resultere i en rottende ostemasse. Hovedet skal være klar til at høste 5-15 dage efter binde. Høst, når hovedet er kompakt, klart hvidt og ca. 6 "i diameter.
Broccoliis høstet, når hoveder er tætte, 3" -6 "i diameter, og før de enkelte blomsterknopper er skelnelig eller gule blomster kan ses. Skær 8 "-10" af stamme med hovedet. Broccoli skal afkøles så hurtigt som muligt og opbevares under kølige forhold efter høst for at bremse blomsterudviklingen. Sidehoveder udvikles hurtigt efter fjernelse af terminalhovedet, medmindre Cultivar anvendt er en nonsprouteret type. Høstning kan fortsætte i flere uger.
Brusselsspirts, hvis spirer er fast og er af den ønskede størrelse for markedet. Spirer kan høstes sekventielt, arbejder stænglen som sæsonen
Kale og skoler kan høstes ved at afskære hele planter nær grundniveau. Hele planter bliver så bundtede, eller nedre blade kan fjernes fra planter og enten bundt eller pakket individuelt . Flere høst er mulige. På grund af deres letfordøjelighed bør Kale og Collards holdes så tæt på 32 F som muligt. Ved denne temperatur kan de holdes i 10-14 dage. Relativ luftfugtighed på mindst 95% er ønskelig for at forhindre visning. Luftcirkulationen bør være tilstrækkelig til at fjerne åndedræt, men overdreven luftcirkulation vil fremskynde transpiration og visning.
