I had a question about herbs. Basically everything I read shows people putting several seeds within 1 starter pot with any herb being basil, oregano, chives, catnip, parsely, spearmint, or rosemary. My question is how much does just 1 seed yield of these things. Are they planting like 10 in a pot just to be sure that 1 germinates and then plan to cut all the others out if many germinate or do you actually need this many to yild something from these herbs. Reason im asking is because when I read the seed packets it says that plants should be 12 inches apart and in a square foot garden that would be like having 1 plant per square and that just doesnt seem like you would get much from it. So could someone please clearify this for me. Thanks.
