Formula Used
Plantable Area = Total Area × Coverage Percentage × (1 − Path Percentage)
Plants Required = Plantable Area ÷ Area Per Plant
Area Per Plant = Spacing²
Area Per Plant = 0.8660254 × Spacing²
Adjusted Quantity = Base Quantity ÷ Establishment Rate × (1 + Extra Allowance)
How to Use
Enter the garden shape and dimensions. Select the correct measurement units. Then choose your usable planting percentage.
Add climate, sunlight, soil, and moisture details. Select preferred plant groups and pollinators. Strong filters produce fewer matching plants.
Set spacing, establishment rates, and budget values. Add a custom species when needed. Submit the form to generate recommendations.

Frequently Asked Questions
What makes a plant bee-friendly?
Bee-friendly plants offer accessible nectar or pollen. They bloom when local pollinators need food. Single flowers usually provide easier access.
Why is continuous bloom important?
Different bees forage during different seasons. Bloom gaps can create food shortages. Mixed flowering periods improve reliable forage.
Should every plant be native?
Native plants often support local wildlife well. Suitable non-native plants can also provide forage. Avoid invasive species in every garden.
How accurate is the plant quantity?
The count uses area and average spacing. Mature widths vary between plant varieties. Adjust quantities for local growth habits.
Why add extra plants or seeds?
Some plants fail after installation. Seeds may not all germinate successfully. Extra material helps reach final coverage.
Can I plan a balcony garden?
Yes, choose the balcony garden option. Use compact plants and suitable containers. Check weight and watering limitations carefully.
Does flower colour matter?
Bees perceive several colours very well. Diverse colours help different pollinators locate flowers. Flower shape also affects accessibility.
How does the water estimate work?
Each recommended plant has a planning allowance. The calculator multiplies allowance by plant quantity. Weather and soil can change requirements.
Can pesticides reduce bee value?
Some insecticides can harm visiting pollinators. Systemic products may remain inside plant tissues. Use integrated pest management whenever possible.
Why are some filters too restrictive?
Climate and safety filters remove unsuitable plants. Several strict filters can eliminate most choices. Relax one setting and recalculate.
Is this calculator professional planting advice?
This tool provides planning estimates only. Local conditions and regulations can differ. Confirm selections with regional horticultural experts.
