Rank layout patterns
Compare within-row, stripe, checkerboard, edge-row, and block layouts by overlap, ratio fit, and spacing penalties.
Orchard Pollination Planner
Enter the main cultivar, pollinizer cultivar, bloom overlap, and planting ratio to generate orchard pollinizer mix patterns.
Apples, pears, sweet cherries, sour cherries, and almonds are the primary targets, but custom orchard blocks are supported too.
Built for apples, pears, cherries, and almonds
Scores candidate patterns automatically
Uses cultivar names, bloom overlap, and ratios together

How to Use
- Choose a crop preset, or switch to custom and enter your own orchard species or cultivar name.
- Enter the main cultivar, pollinizer cultivar, bloom overlap, and your target pollinizer ratio.
- Set the planting basis, spacing, and layout mode, then generate candidate patterns.
- Review warnings, compare the pattern scores, and copy or export the result for field planning.
Examples
Apple block with a local mix
Input
Apple, main cultivar Gala, pollinizer Fuji, bloom overlap 72%, ratio 1:7, 12 rows × 24 trees, metric units
Output
Within-row mixing is recommended. The planner shows 288 total trees, 36 pollinizers, and 252 main trees.
Pear rows with a clearer stripe pattern
Input
Pear, main cultivar Bartlett, pollinizer Conference, bloom overlap 64%, ratio 1:9, 10 rows × 20 trees, metric units
Output
Row stripes are recommended. The planner shows 200 total trees, 20 pollinizers, and a ratio fit that stays close to the crop range.
Sweet cherry block with an alternating layout
Input
Sweet cherry, main cultivar Bing, pollinizer Lapins, bloom overlap 85%, ratio 1:5, 12 rows × 14 trees, metric units
Output
Checkerboard mixing is recommended. The planner shows 168 total trees, 28 pollinizers, and a strong bloom overlap match.
Almond block with border emphasis
Input
Almond, main cultivar Nonpareil, pollinizer Carmel, bloom overlap 78%, ratio 1:4, 8 rows × 15 trees, metric units
Output
Edge-row mixing is recommended. The planner shows 120 total trees, 24 pollinizers, and a simple border-focused layout.
Glossary
- Main cultivar
- The main orchard cultivar that makes up most of the block.
- Pollinizer
- A cultivar that provides compatible pollen and is counted separately from the main trees.
- Bloom overlap
- How much of the bloom window is shared between the main cultivar and the pollinizer cultivar.
- Compatibility group
- A manual compatibility note such as an S-allele group, line code, or local orchard classification.
- Normalized ratio
- The pollinizer share converted into a practical main-to-pollinizer ratio.
- Edge rows
- A layout that concentrates pollinizers on the border rows of the orchard block.
Formulas
- Pollinizer share = pollinizer trees ÷ total trees
- Main trees = total trees - pollinizer trees
- Normalized ratio = 1 : round((1 - share) ÷ share)
- Pattern score = overlap score × 0.40 + ratio fit × 0.25 + dependence fit × 0.15 + pattern bonus × 0.20
- Distance penalty is added when spacing pushes compatible trees farther apart than the crop target.
- Auto mode picks the highest-scoring candidate pattern.
FAQ
Does the planner verify pollination compatibility automatically?
No. You can enter a compatibility group, but the planner still treats it as a manual note. Local cultivar guidance should decide the final mix.
Why do I need bloom overlap?
Bloom overlap helps rank the candidate patterns and warn when the pollinizer window looks too small for the crop preset.
Can I use local cultivar names or other languages?
Yes. Custom mode accepts any orchard species or cultivar name, and scientific names are optional.
Is the ratio a prescription?
No. The planner scores and normalizes a ratio, but it does not guarantee field success or replace local trial data.
Does the tool work offline?
The page runs in the browser and keeps data locally by default. Nothing is uploaded unless you choose to copy or export it.
Notes
- This planner is a heuristic aid, not a pollination guarantee.
- Bloom timing, climate, wind, and cultivar compatibility vary by region, so local orchard knowledge should always have the final say.
- When you work across countries or language teams, use the scientific name or a compatibility group to keep the notes unambiguous.
