Thanks for posting the link! The photo is so pretty! I can't wait for this to bloom. If I see fertilizer burn (the black spots on the leaves), does this mean I should use more diluted fertilizer? I'm currently using 1/4 tsp per gallon of water.
Also, they like a good chilling in the fall to bloom. I leave mine outside until the end of October, protecting it from frost. They are quite tough. Give it as much light as you can without burning it. Morning light is good.
