My plant is actually three. The largest is probably 10 times the size of the other two. I have always wanted to separate the three, but have been nervous about hurting them. I think the plant is strong enough now to take it, so I will do it soon.
I heard back from Martha Kent, a Staff Horticulturist from the Fairchild Tropical Botanic Garden. She advised no more blood meal or Holy Tone for now, because rapid growth promotion is not always good for flower production. She also said the house heat during winter months may be tough on it. I think I will try running a humidifier near it during those months.
There is a internet site called The Garden Helper with some basic advice. I have seen it before, but found what they suggest was not really as specific as I hoped.
