It must be isolated from other carrot varieties as well as wild carrot (Queen Anne’s Lace) by at least 0.5-2 miles unless the flowering plants are enclosed in a cage. Year 2: Producing the carrot seedĬarrot is highly outcrossing and insect-pollinated. Trim the tops to ½ inch above the root crown, taking care not to remove the apical bud.
Save only disease-free, true-to-type roots. Do not wash the roots or rub them with a brush. Any soil clinging to the root should be wiped off by hand.
Roots can be harvested when the soil is moist, but not wet. Similar to onions, carrot populations need to be maintained with at least 120-200 plants, so initially select 225 or more since some may be lost to rot during the winter storage. Carrots being selected for root characteristics including shape, color, and core distribution.Ībove ground characteristics (foliage and crowns) can be selected for during the growing season. Once some roots have reached market size, selections can be made for desirable root characteristics. They should be direct seeded in early summer and thinned to 1-2 inches apart. Carrots prefer a soil with a high water-holding capacity and need a consistent water supply. Year 1: Producing the carrot cropĬarrot production is most successful with dry, warm to hot summers in sandy or silty loam soils with high nitrogen and phosphorus but without excess nitrogen. Carrot Seed ProductionĬarrots are a biennial, so seed production must take into account a two-year reproductive cycle.
