The high-yielding, blunt-tipped, deep-orange roots average 6-7" long and have excellent uniformity, which means more marketable roots. Compared to Nelson, Romance has better, more well-rounded flavor; though, like Nelson, the flavor is consistently good across soil types. The roots are brighter orange after washing, and the tops are more vigorous. This full-season Nantes has a tapered root, rather than the true "cigar" shape of an early Nantes. Great for bunching. Medium-sized, healthy tops. Also available with NOP-compliant pelleting. Avg. 204,000 seeds/lb. Packet: 750 seeds.
CULTURE: Carrots require well-drained soils, with a pH range of 6.0-6.8. Deep, loose, and fertile sandy loams and peat soils with good moisture-holding capacity grow the straightest and smoothest roots.
PLANTING: Sow from early spring to midsummer, 3/4-1" apart (about 30 seeds/ft.), 1/4- 1/2" deep, in 2" wide band, or single rows 16-24" apart. For minimum soil compaction, use raised beds with 2 or 3 rows 16-24" apart, beds 5-6' on center. Sprinkle the soil surface to keep moist. Don't allow soil to crust before the emergence of seedlings which takes 1-3 weeks, depending on temperature and moisture. If soil moisture during germination is an issue, we recommend using pelleted seed. If necessary, thin young seedlings to 3/4-2" apart, depending on root size desired. Keep weed-free by tine weeding and shallow hoeing. To prevent greening, cover exposed crowns.
DISEASES: Blights can reduce yield and quality. Alternaria blight shows as brown-black lesions edged with yellow on leaf margins beginning on oldest leaves. Leaflets may shrivel and die. Cercospora blight first appears as small dark spots with yellow margins on the younger leaves and stems. To prevent blights, practice a 3-year crop rotation. Copper fungicides (see Index) can be employed as a preventive measure or control.
INSECT PESTS: Carrot rust flies and wireworms. Provide fertile growing conditions and avoid ground recently in sod if possible. Exclude adult insects with fabric row covers (see Index).
HARVEST: Carrots may be dug any time after they reach the desired size. Generally the best harvest period lasts about 3 weeks (longer in cool, fall weather), after which time the roots may crack or the taste and appearance may decline. Make a few sowings at 3-week intervals for a continuous supply of tender carrots at their prime.
STORAGE: Plant carrots intended for winter storage about 100 days before expected fall frost. Carrots store best at 32°F (0°C) and 98% relative humidity.
AVG. SEEDING RATE: 1 M/33', 5M/166', 25M/830', 720M/acre at 30 seeds/ft. in rows 24" apart.
CARROT TYPE: Each type is identified in catalog copy. Nantes are medium length and cylindrical. The Shipping/Imperator types have the extra length and durability required in conventional packaged carrots, and perform the best in deeply worked soil. Chantenays are top-shaped and suitable for shallow or heavy soil. They are suitable for tropical winter production (CA, TX, FL) or temperate summer production (where winters get below 45°-50°F (7°-13°C). SIZED SEEDS: Standard except where noted.

Days To Maturity
Average number of days from seeding date until ready for harvest.
Plants can be Annuals (single growing season), Perennials (grow year after year), Tender Perennials (grow year after year in warmer climates; and in some cases when given special protection in colder climates), or Biennials (require two years to mature).
Hybrid: The offspring of a cross between two or more distinct parent lines, usually of same species, and selected for improved traits. Open-pollinated: A non-hybrid variety that can reproduce itself in kind, demonstrating relatively stable traits from one generation to the next.
