Planting Depth Guide: How Deep to Plant Your Flower Bulbs for a Thriving Garden
Planting flower bulbs at the correct depth is essential for healthy growth and vibrant blooms. If planted too shallow, bulbs may not establish properly; too deep, and they may struggle to emerge. This guide provides the ideal planting depths for popular bulbs, ensuring a beautiful and flourishing garden.
Why Planting Depth Matters
The depth at which you plant a bulb affects its ability to take root, absorb nutrients, and grow strong stems. The general rule of thumb is to plant bulbs at a depth roughly three times their height, but specific flowers have unique requirements.

- Water After Planting: Moisture helps bulbs establish roots, but avoid overwatering.
- Mulch for Protection: A light layer of mulch helps retain moisture and insulates bulbs during colder months.
