Additional Information
Fertilizer Requirements
Use 1 to 2 pounds all purpose fertilizer (20-20-20) per 100 square feet of garden area. Carrots usually require no side dressing of fertilizer later in the season. If replanting in midsummer, apply an all-purpose fertilizer to the soil.
Water Utilization
As newly planted carrots establish themselves in the soil, it is important to keep the soil moist, but not water-logged.
Established carrots need water when the top 2" of soil is dry.
Plant Development and Care
Harsh flavor comes from terpenoids and sweet flavor comes from sugar. A balance of the two makes great tasting carrots.
Germination Time (Days)
At 41°F, 51 days At 50°F, 17 days At 59°F, 10 days At 68°F or higher, 6 to 9 days
Seed Germination and Temperature Range
Grows best at soil temperatures between 60° and 70°F. Lower temperatures increase root length with less enlargement. Higher temperatures decrease length and carrots can become stubbier
Common Fertilizer Deficiencies
Excess nitrogen causes excessive top growth and root forking
