I'd like to try growing some cilantro seeds in pots on my patio. I don't have the option of growing anything in the ground. I've been searching the internet for information, and some sites say that you have to plant cilantro in pots at least 12 inches deep because they have a taproot. Is this correct? I also read that they don't take transplanting very well.
The only pot of that depth that I have is absolutely massive, and I'm concerned about over-potting and drainage. Should I add a bunch of perlite and vermiculite to my commercial potting mix?
