The secret to keeping Norfolk Island pine healthy is to give it ample light and humidity. In low light, the lower branches may turn brown and fall off. If the air is too dry, it becomes a prime target for spider mites, a common houseplant pest. In its native habitat, Norfolk Island pine can reach 200 feet tall, but don't worry -- indoors, it seldom grows taller than 10 feet.
