Rick: I used a peanut based compost one year with very poor results. I usually go with a potting soil based compost c extra perlite.

I understand that they're heavy feeders, and prefer lots of sun, regular moisture in a very cool environment, and also read that they can be a little crowded in the pot? Any practical advice here will be appreciated. Thanks, Rick Buell
