One of the questions we are most often asked is ‘How far apart should I plant these seedlings?’ There are a range of answers to that question, mostly based on the way you plan to harvest your plants. If you plan to regularly pick outside leaves as the plant continues to mature, you can plant them a bit closer together. If the plant is a compact or dwarf variety, you can also fit a few more in your row.
Here are some general guidelines:
