I'm going to try and learn gardening

Title pretty much says it, I've been getting annoyed by how small the packs of basil are that you buy from the supermarket, so I'm planning on buying a basil plant and some soil tomorrow. I've watched a few videos on growing basil and plants in general, including how I can grow more of them (apparently the word for it is 'propagating', which is a very cool word).

I'm a bit hesitant because I've never attempted gardening before, so I don't want to buy stuff only to have it fail. For now I'm keeping it limited on the stuff I buy to just the plant and some soil, but I've seen videos that allow for indoor setups with heat lamps and heating pads, which maybe if I get more into it I'll do further on down the line, but for now I'm not going to get ahead of myself.

For now I'm starting with basil, but if I can successfully get that going and propagate it, I'd like to also try growing spring onion next. Who knows from there!

If anyone has any advice for a brand new gardener, or you have a gardening experience of your own that you'd like to share, please let me know! Thanks for listening :)
