Daucus carota (74 days) F-1 hybrid. In our spring 2019 storage-carrot tasting, we were hoping to simply confirm newcomer Naval’s refined dominance over well-known Bolero. Then out popped uniform thick deep orange 9" Newhalls from their bin, looking as perfect as the fall day when we stowed them away. With eyebrows raised in wonder after crisp sweet juicy sampling, we realized we now had two candidates who easily danced Bolero right off the table. Newhall is a bulky continental Nantes-type like Bolero, but with much better long-keeping ability and flavor. The impressive cylindrical crack-resistant roots with a slight taper are matched by strong healthy tall tops. Intermediate resistance to ALTS, BR, TLS, PM, LR. ④

⅛ oz packet sows 35 ft; 1 oz, 280 ft. 1 gram packet has more than 400 seeds and sows about 10 ft.
Carrots average 18,000 seeds/oz with significant variations among varieties.
Days to maturity are from seedling emergence after direct sowing.
Culture: Very hardy. Early carrots can be sown by late April. For fall crop or winter storage, seed in early summer. Minimal germination temperature 40°, optimal range 60–85°. Can take up to 3 weeks to germinate; keep rows from drying out for faster emergence. Thinning is critical: At 3" high thin to ½" apart, at 6" thin again to 1-2" apart.
ALTS: Alternaria Leaf Spot
PM: Powdery Mildew
BR: Black Rot
TLS: Target Leaf Spot
LR: Licorice Rot
ALTS shows up first on the oldest foliage as brown-black spots edged with yellow. Foliage blackens and shrivels as it develops and spreads. Maintaining a good crop rotation is the best preventive.
