🌷 Bulb Spacing Calculator
Optimize bulb layouts for flower beds, borders, or containers by choosing the right spacing and pattern.
Grid spacing aligns bulbs in straight rows and columns.
How to Use This Calculator
Measure planting area
Record the interior length and width of beds or planters in inches.
Select recommended spacing
Use bulb packaging or horticulture guides for ideal spacing.
Choose pattern
Grid works for formal layouts; staggered provides fuller displays.
Formula
Rows = ⌊Width ÷ Spacing⌋
Bulbs/Row = ⌊Length ÷ Spacing⌋
Total Bulbs = Rows × Bulbs/Row
Staggered adds offset rows at half spacing.
Floor functions (⌊ ⌋) round down to whole bulbs that physically fit within the bed dimensions.
Full Description
Proper bulb spacing ensures adequate airflow, prevents overcrowding, and creates beautiful displays. Use tighter spacing for dense drifts or wider spacing for naturalized plantings.
Consider bloom time and plant height when mixing varieties to avoid shading smaller bulbs.
Frequently Asked Questions
Should I plant bulbs closer than recommended?
You can group bulbs slightly closer for dramatic displays but monitor for disease and divide every few years.
How deep should bulbs be planted?
Depth typically equals 2–3 times the bulb height. Follow variety-specific instructions.
Do I need staggered spacing?
Use staggered spacing for fuller coverage in formal beds or containers.
How do I mix different bulbs?
Group by bloom time and height, and adjust spacing to prevent taller bulbs from shading shorter ones.
