How to Use This Calculator
  1. Enter the total area you are dedicating to pollinator plants in square feet.
  2. Enter the percentage of native species you plan to include — native plants attract significantly more pollinators than non-natives.
  3. Select how many bloom seasons you want covered: 1 (spring only) through 4 (all seasons).
  4. Choose your sun exposure level and indicate whether you will include a water feature (birdbath, shallow dish, etc.).
  5. Review the Total Plants Needed, species diversity requirements, and early/mid/late bloom plant breakdowns.
  6. Use the Pollinator Score (1–100) to benchmark your garden design and make adjustments to reach a higher score.

What each input means

Garden Area
Total area dedicated to pollinator planting.
Native Species %
Percentage of plants that are native species. Natives attract more pollinators.
Bloom Seasons Covered
1=Spring only, 2=Spring+Summer, 3=Spring+Summer+Fall, 4=All four seasons.
Sun Exposure
1=Full sun (6+ hrs), 2=Partial sun (4-6 hrs), 3=Shade (< 4 hrs).
Water Feature (0=No, 1=Yes)
Whether the garden includes a birdbath, fountain, or shallow water dish.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Garden Area = 100, Native Species % = 70, Bloom Seasons Covered = 3, Sun Exposure = 1 = 5 input(s) provided
  2. Calculate Total Plants Needed
    Total Plants Needed
    50 = 50
  3. Calculate Pollinator Score
    Pollinator Score
    68 = 68
  4. Calculate Species Needed
    Species Needed
    10 = 10
  5. Calculate Early Bloom Plants
    Early Bloom Plants
    17 = 17
