How much space do tulips need?

Tulips generally need about 4 to 6 inches of space between each bulb when planting to ensure proper air circulation and growth. When planted in groups or clusters, spacing can be slightly closer, around 3 to 4 inches apart. Additionally, the planting depth should be about 6 to 8 inches to protect the bulbs and promote healthy development. Proper spacing helps prevent overcrowding and reduces the risk of disease.
