I grow all sorts of stuff in pots! Tomatoes are really easy - and there's nothing like going outside to pick your own lunch! I also do parsley, basil, thyme, sage, mint, rosemary, lemon balm, etc. in pots. I haven't had much luck with my coriander, but everything else has been easy. If you want to grow things from seed, you need to start ASAP! Time's running out! Otherwise, wait a while and buy small plants from your garden centre instead.
