Recommended Depths for Plant Spacing
| Project / Use Case | Recommended Depth |
|---|---|
| Annual Flowers | 6–12 inches apart |

| Small Shrubs | 2–3 feet apart |
| Large Shrubs / Hedges | 4–6 feet apart |
How to Calculate Plant Spacing Volume
Most landscaping suppliers sell plant spacing by the cubic yard. To convert your project area to cubic yards, use this formula:
Our calculator also multiplies your cubic yard result by 0 tons/yd³ (the standard density for plant spacing) to show estimated weight — essential if you are hauling the material yourself or need delivery pricing.
Pro Tips for Plant Spacing Projects
Staggered (triangular) spacing provides a fuller, more natural look and reduces soil erosion compared to square grid spacing.
Always leave a border gap equal to half the spacing distance from the edge of the bed so plants do not spill over path boundaries.
Mulch the empty spaces between young plants immediately to retain moisture and prevent weeds from occupying the open gaps.
