Overcrowding and rocky soils result in poor quality roots. If radishes were mixed with the carrots, pull and eat them as they mature. Five to 10 feet of row per person should supply enough fresh carrots for table use. One foot of row will yield about 1 pound of carrots. After Planting Keep carrots free of weeds, especially when they are small.
Weeds use nutrients and moisture and cause reduced carrot yields.
Scratch the soil lightly around the plants to prevent crusting. Water the plants as required to keep the soil moist to a depth of about 3 inches. Scatter 2 tablespoons of fertilizer per 10 feet of row beside the plants when the tops are about 4 inches high. Fertilize again when tops are 6-8 inches high if the tops become pale. Before using a pesticide read the label.
