How to Use This Tool

- Select your main crop from the dropdown menu (e.g., Tomato, Basil, Cucumber).
- Choose your garden type (Raised Bed, In-Ground, or Container) to get tailored spacing tips.
- Optionally filter results by preferred benefit (Pest Control, Growth Boost, Pollinator Attraction).
- Click the "Generate Companion Chart" button to view your results.
- Use the Reset button to clear all inputs and start over, or Copy Results to save your chart.
Formula and Logic
This tool pulls from a verified database of common companion planting pairings used by home gardeners. The logic follows these core principles:
- Companions are selected based on mutual growth benefits, pest deterrence, or pollinator attraction.
- Plants to avoid are identified based on competition for nutrients, pest attraction, or growth inhibition.
- Spacing recommendations adjust based on garden type to account for soil depth and space constraints.
- Benefit filters sort results to highlight pairings that match your specific gardening goals.
Practical Notes
Apply these real-world tips to get the most out of your companion planting chart:
- Raised beds allow closer spacing than in-ground gardens due to better soil quality and drainage.
- Container gardens require dwarf or bush crop varieties for best results with companion planting.
- Marigolds are a universal companion plant suitable for nearly all vegetable garden layouts.
- Rotate crops annually even with companion planting to prevent soil nutrient depletion and pest buildup.
- Always check seed packets for specific spacing and sunlight requirements for your chosen crops.
Why This Tool Is Useful
Companion planting can reduce the need for chemical pesticides and improve garden yields, but remembering hundreds of plant pairings is difficult. This tool eliminates guesswork for home gardeners by:
- Providing instant, accurate pairings for 10 common garden crops.
- Tailoring spacing advice to your specific garden setup.
- Filtering results to match your priority (pest control, growth, pollinators).
- Letting you copy results to plan your garden layout digitally or on paper.
Frequently Asked Questions
Can I use this chart for flower gardens too?
This tool focuses on common vegetable and herb crops, but many pairings (like marigolds with vegetables) also work for flower gardens. For flower-specific companion planting, check crop-specific guidelines for your blooms.
What if my crop isn't listed in the dropdown?
The tool currently includes 10 of the most common home garden crops. For unlisted crops, refer to general companion planting guidelines: most herbs pair well with vegetables, and flowering plants like marigolds are near-universal companions.
Do I have to follow the spacing tips exactly?
Spacing tips are general recommendations. Adjust based on your specific crop varieties (dwarf vs. standard) and local growing conditions. Overcrowding can reduce yields and increase pest risk, so err on the side of more space if unsure.
Additional Guidance
For best results with companion planting:
- Start with 2-3 companion pairings in your first season to test results in your local climate.
- Pair tall crops (like tomatoes or corn) with low-growing crops (like lettuce or carrots) to maximize space.
- Plant pest-repelling companions like marigolds or basil around the perimeter of your garden for maximum protection.
- Keep a garden journal to track which pairings work best for your specific soil and sunlight conditions.
