Pelleted carrot seed
This year we are offering pelleted carrot seed for three varieties. 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.
⅛ oz packet sows 35 ft; 1 oz, 280 ft. 1 gram packet has more than 600 seeds and sows about 10 ft. Carrots average 18,000 seeds/oz with significant variations among varieties.
Culture: Very hardy. Early carrots can be sown by late April. Can take up to 3 weeks to germinate; keep rows from drying out for faster emergence. Sow carrots for winter storage in mid-late June. Thinning is critical: At 3" high thin to ½" apart, at 6" thin again to 1" apart. Minimal germination temperature 40°, optimal range 60–85°, optimal temperature 80°. Emergence takes 17 days at 50°, 10 days at 59°, 6 days at 77°, 48% normal seedlings at 41°, 96% normal at 68°.
- ALTS: Alternaria Leaf Spot
- CLS: Cercospora Leaf Spot
- P: Pythium
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.
