Benefits of Garden Planning

Space Optimization

Triangular spacing patterns fit 15-20% more plants than traditional rows. Every square inch is utilized for maximum productivity.

Cost Savings

Buy exactly the right number of plants and seeds. Avoid overbuying or gaps in your garden that waste money and space.

Increased Yields

Companion planting can boost yields by 20-30% through improved pollination, pest control, and nutrient cycling.

Natural Pest Control

Strategic plant placement deters pests without chemicals. Marigolds, nasturtiums, and herbs protect vulnerable crops naturally.

Time Efficiency

Planned pathways and logical groupings reduce maintenance time. Access plants easily for watering, weeding, and harvesting.

Healthier Soil

Crop rotation planning prevents nutrient depletion and disease buildup. Maintains soil fertility year after year without heavy fertilization.

Frequently Asked Questions

What's the difference between square and triangular spacing?
Square spacing arranges plants in traditional rows and columns. Triangular (offset) spacing staggers rows, fitting 15-20% more plants in the same area while maintaining proper spacing for each plant's needs.
How accurate are the yield estimates?
Estimates are based on average yields under ideal conditions with proper care. Actual results vary by climate, soil quality, weather, and experience. Use estimates as planning guidelines, not guarantees.
Can I mix different plants in one calculation?
Yes! The companion planting tool lets you combine compatible plants. The calculator adjusts spacing automatically based on each plant's requirements and shows optimal arrangement patterns.
Does the calculator work for raised beds and containers?
Absolutely! Enter your raised bed or container dimensions just like in-ground gardens. The calculator works for any rectangular growing space from 1×1 feet to large plots.
How much garden space do I need for self-sufficiency?
For partial self-sufficiency with vegetables, you need around 50 m² (540 sq ft). For full self-sufficiency including fruit, plan for 100-150 m² (1,100-1,600 sq ft) per person.
