Hi Loreena, here is a link that could help you with these questions,
outdoor grow guide When to plant all depends on were you live and it's year round weather, I plant the seeds a half inch deep maybe a slight bit more, The plants like full sun, they will grow with less sun but it won't be as healthy and produce as much. And another thing you have to watch out for is the wild animals, some of them love to eat the plant and also certain bugs and slugs,,, but with all of that said, If you are not going to watch them throughout their growth, there are some that can very well make it,, If you have some bag seed I would say go for it and see what happens,, Do go to that link and read,, if you have anymore questions do ask,,,,,
