Which are the easiest herbs to maintain indoors? I want to be able to reach over and have the freshest possible herbs available to me in an instant. I don't want to have to go around watering a dozen potted plants a day though, so can I plant a group of them in one pot? Thanks
Although most herbs are regarded as easy to grow and the majority of herbs will grow indoors - especially if placed in a south, southeast or southwest facing window - although an east facing window will probably suffice for some - the best choice for indoor growing are the soft herb varieties like mint, basil, chives, cilantro and parsley - with parsley being a really good choice for indoor growing - as it requires a lot less light than some of the other herb varieties.
As for growing multiple herbs in a one pot - so long as you bear in mind that herbs grown together in one container generally tend to be smaller than those grown in individual pots - there really isn't any reason why you can't have a one pot herb garden - so long as you make sure that all the herbs that you group together share the same sun, water and soil preferences - like for example -
Rosemary, Oregano, Sage, Thyme and Marjoram all do well together in one container as they all have similar needs in terms of sunlight, lean soil and like to be kept relatively dry - whereas the best choice for those herbs that require plenty of moisture as well as sunlight would be any of the following Mint, Basil, Chives, Cilantro, Tarragon and Parsley.
I would however just add - that its not a good idea to grow any mix of the mint family in one container - like for instance- peppermint, spearmint, orange mint, chocolate mint, pineapple mint or lemon balm - as when grown together - they have a tendency to interbreed and produce new strains that are very unlikely to taste anything like you were expecting - especially as the flavor is generally quite the opposite of delicious.
