Tulip bulbs are underground storage organs that allow tulips to survive through winter and bloom in spring. These bulbs store nutrients and energy, enabling the plant to grow and produce flowers. They come in various shapes, sizes, and colors, making them popular in gardens and landscapes. To plant tulip bulbs, choose a sunny location with well-drained soil. Dig a hole about 6 to 8 inches deep, place the bulb with the pointed end facing up, and cover it with soil. Water the area lightly, and the bulbs will begin to grow as temperatures warm in the spring.
