Plan your home vegetable and herb garden with this companion planting chart tool. It helps you identify which plants grow well together to boost yields and reduce pests. Use it to organize raised beds, container gardens, or backyard plots.
💡 Tip: Start by selecting your main crop to see tailored companion recommendations for your garden type.
How to Use This Tool
Follow these simple steps to get tailored companion planting recommendations for your home garden:
- Select your main crop from the dropdown menu (e.g., Tomato, Basil, Kale).
- Choose the companion type you want to view: all companions, beneficial plants, nitrogen-fixing varieties, shade-providing crops, or plants to avoid.
- Pick your garden type (raised bed, container, in-ground, or vertical) to get spacing adjustments specific to your setup.
- Click the "Get Companions" button to view your results.
- Use the "Copy Results" button to save your companion list for garden planning, or click "Reset" to start over.
Formula and Logic
This tool uses a static, research-backed database of common companion planting pairings for 10 popular home garden crops. The logic follows these steps:
- Match your selected main crop to its pre-loaded companion data, including beneficial plants, nitrogen-fixing partners, shade providers, and plants to avoid.
- Filter the companion list based on your selected companion type (e.g., only show nitrogen-fixing plants if that option is chosen).
- Apply spacing adjustments based on your garden type: raised beds reduce spacing by 10-15% for intensive planting, containers reduce spacing by 20%, and vertical gardens reduce row spacing by 30%.
- Display a detailed breakdown of compatible plants, benefits, spacing, and common pairings for your selected crop and garden setup.
Practical Notes
Companion planting works best when paired with other home gardening best practices:
- Rotate crops annually to prevent soil nutrient depletion and pest buildup, even when using companion planting.
- Container gardeners should use at least 5-gallon pots for large crops like tomatoes and peppers, even with reduced spacing.
- Marigolds are a universal beneficial companion for almost all vegetable crops and work well as border plants in any garden type.
- Three Sisters planting (corn, beans, squash) is a traditional companion planting method that maximizes space in in-ground or raised bed gardens.
- Always observe your plants: if a companion pairing seems to stunt growth, remove the companion and adjust your layout.
Why This Tool Is Useful
Home gardeners of all experience levels can use this tool to simplify garden planning:
- New gardeners avoid common mistakes like planting tomatoes near brassicas, which can stunt growth.
- Experienced gardeners maximize small spaces like balconies or container gardens with tailored spacing recommendations.
- Kitchen gardeners growing herbs like basil can improve flavor and repel pests by pairing with compatible vegetables.
- It saves time researching individual plant pairings, with all data in one easy-to-use interface.
- Results can be copied and shared with family or community garden members for collaborative planning.
Frequently Asked Questions
Can I use this tool for flower gardens?
