Birds Nest Spruce is not drought-tolerant and requires regular watering. It prefers moist, well-drained soil and should not be allowed to dry out. If the plant is exposed to prolonged periods of drought, its fronds may turn brown and fall off. Birds Nest Spruce is a fast-growing tree that can reach up to 20 feet in height, and it is important to provide it with ample water to support its growth.
