We bought a catnip plant at the pet store last year but it died over the winter. So we bought 5000 catnip seeds so we can start our own catnip garden. I want to plant a few in pots to start out with and eventually start a garden outside once the seeds get going. The only info I've found online says that they need a good amount of sun but it doesn't matter if they get lots of water or very little. Does anyone grow catnip, and what does it take to get them growing and keep them alive?
