How many herb seedlings to a 30CM pot?

This year I wish to grow herbs, having a small balcony garden I've brought 30cmx30cm plant pots. So I've started growing my herbs in small trays until seedlings appear, than I will plant them all in individual plant pots, according by the different herb. This is probably a silly question, how many seedlings should I add to one 30cmx30cm pot? I've listed below the herbs I'm growing. Would really find it helpful if someone could lend me some guidance.
  • Parsley
  • Oregano
  • Corriandar
  • Mint
  • Thyme
Thank you for you help!

    Thyme, mint and oregano are perennial and will increase in size year after year, especially mint which spreads quite quickly. About 3 for a pot if you’re planning to keep those for more than a year. 

    Parsley and coriander are grown as annuals, so you can get away with planting around 9 plants in each pot. 

    The pots with herbs you can usually get in supermarkets are definitely overcrowded so they shouldn’t be taken as an example. I hope this helps.

    You’re welcome. Parsley can be late to sprout so give it some time. Mint can very easily propagate from cutting. Coriander can be tricky as it bolts quickly in hot dry weather. My favourite herb to grow for soups is lovage. It’s perennial and it can grow quite tall, but I use the thick stalks as vegetable and the leaves to garnish salads and soups. Can be grown from seeds, but you only really need one plant.

    Mint will swamp anything else in the same pot so that one would be best on its own.

    Also consider grouping them according to the conditions they like, e.g. soft leafy herbs like parsley will want more moisture and will tolerate more shade than the Mediterranean types like thyme and oregano.
