Well i have tons of kenya tree and mine go through the same cycle. I have about i would say about 25 branches and 1 MOTHER SHIP. The MOTHER SHIP gives off quite a few a week. I just got a new branch from the mother ship(colony) about a week ago it it does the same thing. Let it be and don't disturb it. It is somewhat like an anemone. It will shrivle up to a brown color and look like a piece of broclie and slowly come back.
