Carrot Irrigation

Germination

• Unlike other stages of development, when carrots can do with a little less water, they need constant watering and moisture from the time the seed is planted until germination. Young seedlings should also be kept constantly moist for the first few days. Irrigate or water the soil as soon as it feels dry to the touch on the surface. Make sure that the water penetrates the soil for several inches.

Regular Irrigation

• After the first several days, water the carrots on a regular basis. The amount of water necessary depends on soil conditions and weather, but in general carrots need about 1 inch of water per week. Consistent moisture is more important than the exact amount of water. Allowing the carrots to dry out between each watering or irrigation cycle could result in cracking and a loss of flavor. Placing mulch around the carrots after they have sprouted can help keep moisture levels consistent.

Irrigation Effects

• While maintaining consistent moisture levels is important, the amount of water does play a role in the development of carrots. Too much water can cause a carrot to sprout hairy and unappealing side roots and become pithy. It can also cause a carrot to form two branches or forks at the end. A lack of water causes not only cracking, but also stunted growth, toughness and a bitter flavor. Although one inch of water per week is usually ideal, irrigation may be increased slightly between the fourth and tenth weeks of growth to help meet a carrot's increased needs during the rapid growth period.

Light vs. Heavy Watering

• Fewer, heavier irrigation cycles are better than more frequent lighter irrigation cycles. Light watering or irrigation results in shallow roots, or short carrots that are not as flavorful. Heavy irrigation or watering that penetrates several inches below the soil encourages carrots to keep growing downward, ensuring proper growth and the best flavor and texture.
