Daucus carota (48 days) F-1 hybrid. Arguably the tastiest carrot for fresh eating in late spring and summer. Repeat winner of our summer taste tests. Mokum’s earliness, slenderness and sweetness transcend its flaws. Blunt Amsterdam-type that sizes extremely quickly with short weak tops, brittle and not machinable. Should be harvested at 5–6" before the roots push out of the ground and develop green shoulders. Although not a versatile full-season carrot, Mokum merits succession planting so you can enjoy it young throughout the summer. Always the first to disappear from our spring patch. Not for storage. Susceptible to ALTS at our Colrain, Mass., plot in 2009 and 2012 but not in 2010. ④

Pelleted carrot seed
Pellets can save time-consuming thinning for both home gardeners and commercial operations. They can be sown by hand or by using precision seeders. Our carrot pellets are size 11.5. Pellets have one major drawback: the process shortens the viable life of the seed. Buy only as much pelleted seed as you need for this season. It will not hold over well. Our pellets use an inert clay coating that is in compliance with NOP standards. At 1" spacing 100 pellets will sow about 8', 250 pellets around 20'. Keep pellets cool and dry prior to planting and maintain steady soil moisture during the germination period.
How to Succeed with Pelleted Carrot Seed
Incorrect use of pelleted seed negates the benefits its higher cost reflects. Success hinges upon being mindful of soil temps (ideally 65-75°) and maintaining proper soil moisture. All carrot seed, but especially pelleted seed, needs consistent moisture. A deep soaking after seeding helps saturate and break apart the clay pellet. After initial watering, it remains of utmost importance to keep soil from drying out.
Home gardeners: Hand sow pelleted seeds every 1". Lay wetted newspaper on top of the seed bed for 5-7 days to keep soil moist during emergence.
Commercial growers: Pelleted carrot seed is best used with a precision seeder. The pellets neatly fit into the singulation mechanisms of the seeder to drop one seed at a time to a set spacing. This minimizes labor-intensive thinning, giving commercial growers added control over this high-maintenance crop. If you don’t have a precision seeder, use raw carrot seed. Either way, cover beds with row cover (laid flat) for 5-7 days to keep soil moist until seeds sprout.
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 75–85°. 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.
