I haven't had to add any further feedings. Both plants leaves are beautifully dark green and they look very healthy. The outdoor girl's sisters had to get some bamboo sticks and strings for support. They are getting top heavy and I woke up to branches hanging down to the ground one morning. So far Dark Phoenix doesn't need support, but she'll be putting on some weight shortly...
@Mrs_Larimar, I don't know to be honest. I don't think paint on the outer layer of the pot will damage the plant. But we'll see, I currently have 4 plants in painted pots.
