I'm very inexperienced with gardening and I got two growing sets from IKEA, including sets for basil, parsley, peppermint, coriander, oregano and thyme. Most of them have begun to grow and it seems they are in good shape so far:
I bought the basil, parsley and peppermint first and the other 3 were added later. Now the IKEA instructions don't tell me a lot about how to take care of the herbs, which is why I'm asking here.
Do I have to repot them at some point? In the IKEA pictures, it seems they can be left in the included pots for a very long time, but I don't know if that's a good thing.
If I have to repot them, can I put a few of them (say 2-3) in a single pot or do I have to put them in separate pots?
They are currently sitting on a window sill facing east inside my living room (I don't have a lot of light in my kitchen unless I turn the lights on). Should I put them somewhere else where they are not exposed to direct sunlight or will they be fine?
How often should I water them? I have some other indoor plants too, and the way I have to take care of them varies a lot, some need the earth to almost always be wet whereas others should be left until the earth has become a bit dry.
Do I need to use fertilizer at some point? Which one?
What do I have to pay attention to if I want them to survive the winter?
And most importantly: When do I know that I can use them for cooking? What do I have to pay attention to when I use them? Should I only use a few branches every time?
Thanks a lot in advance for any help!
