OK, so my grandmother has this giant lemon bush/tree that's been there for longer than I've been alive...and it fruits year round...What I want to know is, how can I store seeds from some of these lemons till I can get around to plant at home?

I've been reading a lot that you aren't supposed to let citrus seeds dry out...if that's the case, CAN you store the seeds for any significant length of time? Then how do you go about germinating them when you're ready to plant?
