Learn to Grow it
This crop can be direct seeded into warm soil after the last spring frost. If you sow a section or row every two or three weeks, you can get a continuous crop.
Space your plants or seeds 6-8 inches apart in well fertilized soil. Plant your seeds 1/4-3/4 in. deep.
Make sure that your soil is well fertilized as this crop is a heavy feeder and takes a lot of nutrients from the soil. Consider adding compost to the soil the year before you plant.
These plants prefer warm weather and soil so they should be grown when temperatures are over 68 degrees F.
