Carrots are good for a small garden if compact varieties are grown.
How to grow
Plant seeds about an inch apart in the row with the rows being about 12 to 16 inches apart. Plant more seeds than necessary to make up for any losses from insects such as cutworms. Plant shallowly, less than one-quarter inch deep. Keep the soil surface moist, and don't allow it to crust while seeds are sprouting. Read more about soil crusting.
Seedlings are weak and if disturbed, don't recover well. It’s best to use drip systems to water to avoid disturbing the roots. Once emerged, carefully thin seedlings so that plant roots are 1 to 2 inches apart in the row. You may need to thin successively, over a period of several weeks, until your row has evenly spaced plants.
