Hello. I just started my first herb garden, as a hobby, because I enjoy
cooking. I love the smell of mint and the many varieties it comes in. I
also have a large garden that I would be happy for mint to take over.
Anyway, I bought some mint plants and some seeds, for experimentation.

So far (about 1.5 weeks) the mint plants in pots are doing fine. I have
Chocolate Peppermint, Pineapple, Corsican, and Apple mint in pots. I
also planted a Orange mint and a Chocolate Mint outside, in a hole
filled with topsoil. Finally, I planted all the seeds in the packet of
regular mint, and spearmint in small pots, with a little topsoil.

Like is said, the potted ones are OK. The ones outdoors are not OK, but
I think it's because of the fact I haven't watered them enough. The
seeds however are not sprouting. Is it because they are too close? I
didn't leave but a few millimeters between each seed. I planted some
basil in a similar way but it seems to be doing alright.

Where did I go wrong?
