Tulips are typically planted about 6 to 8 inches (15 to 20 cm) deep, with the pointy end up. A common guideline is to plant bulbs at a depth roughly three times their height, and to space them according to bulb size and your soil conditions. Key points to consider
- Depth: Aim for 6–8 inches (15–20 cm) in average garden soil. If you have very sandy soil or you’re in a cold climate, you might go a bit deeper to protect from thaw cycles.
- Height and depth relationship: A general rule is three times the bulb’s height. For many tulip bulbs, this places you near the 6–8 inch target.
- Soil and drainage: Tulips hate wet feet. Ensure well-draining soil; if drainage is poor, consider raised beds or amending the bed with organic matter or sand.
- Mulch considerations: Mulch is fine, but avoid piling mulch so deeply that it buries the bulb crown; you still want the top of the bulb near soil level.
- Sun and spacing: Plant in a sunny spot with good air circulation. Space larger bulbs about 3–8 inches apart depending on variety size.
If you have a specific tulip variety in mind, I can tailor the depth and spacing to that variety’s size.
