I managed to get one seed out of ten to actually grow, it's about 10" tall now and the top leaves look great but the bottom ones are withering..I've re-potted it into good compost and have it on the windowsill, I'm watering from the bottom, keeping it on the dry side so it's not drowning..anyone know what's wrong with it, I'd hate to see it keel over after all the trouble getting it to grow :)
