Ficus Benjamina will grow well in a warm, sunny corner away from all drafts. It is a bush when small; as a tree, it can have a traditional trunk, a braided trunk, or a spiral trunk. Yellow leaves indicate the plant needs water. When green leaves fall off or leaf buds turn black, the tree is being over watered. The leaves are generally dark green, and a ficus can grow to varying heights depending upon its location; the more light and warmth, the taller it gets. They use a high amount of water. Ficus trees enhance the decor in homes, offices, businesses, and restaurants.
