1 . Most of us are familiar with carrots.     1     They are a cool-season crop that can tolerate low temperatures. 

    2     Firstly we should ensure that the soil used for deep-rooted types is free of stones. Mix the soil with organic matter, especially during the fall season before sowing. 

Then we should choose a variety of carrots after the soil is prepared.     3    The early ones are usually small, slender and are eaten while they are young; the main crop types are larger and are eaten fresh or stored. 

Early types should be sown in spring as soon as the soil is workable. They may also be sown under covers, though the covers should be removed after a few weeks.     4    Carrot seeds can be sown about 1/2 inch deep. Early carrots should be thinned to 3 inches apart; main crop carrots should be thinned to 1.5 inches. 

Weeds should be removed regularly once the carrots have germinated. Watering is needed every two to three weeks. Watch out for pests and diseases.     5     Protect against carrot rust flies by surrounding the patch of young carrots with a protective barrier 2 to 3 feet high. Use either fine netting or plastic as barriers. 

Early carrots can be harvested about seven to nine weeks after sowing and main crop carrots should be harvested after ten to eleven weeks.
