Step 1: Plan to plant seeds outdoors 3 to 5 weeks before the last spring frost date.
Step 2: Make sure your soil is free of stones; carrots need deeply tilled soil that they can push through.
Step 3: Have you ever seen a carrot that has grown “legs” or forked? Fresh manure, or even recently applied rotted manure, can cause carrots to fork and send out little side roots. Don’t use it before you plant your seeds.
Step 4: Plant seeds 3-4 inches apart in rows. Rows should be at least a foot apart.
Step 5: Once plants are an inch tall, thin so they stand 3 inches apart. Snip them with scissors instead of pulling them out to prevent damage to the roots of remaining plants.
Step 6: Water at least one inch per week.
Step 7: Carrots are mature at around 2 ½ months and ½ inch in diameter. You may harvest whenever desired maturity is reached.
