A free printable companion planting chart for vegetables gives you a quick reference for which crops grow well together and which ones should be kept apart. This guide shows you how to find or build a reliable chart, read its entries correctly, and turn it into a planting layout you can actually use this season.
What a Companion Planting Chart Actually Tells You
Most charts list pairs of vegetables marked as “good,” “neutral,” or “bad” neighbors. The reasons behind these ratings are usually practical: some crops shade or support each other, some deter common pests, and others compete hard for nutrients or water. Treat each entry as a starting suggestion rather than a guarantee, since results depend on your soil, climate, and how closely you plant.

Before you print anything, check that the chart lists the specific varieties or crop families you grow. A generic line such as “beans” does not tell you whether pole beans or bush beans will suit your tomato bed.
Choose and Print a Reliable Chart
Look for charts that cite their sources, include spacing notes, and cover the vegetables you plan to grow. Many university extension offices publish companion planting guides that are free and research-based, and these make a sound base. Once you have a chart, print it at full page size so the text stays readable when you carry it into the garden.
If you want something more tailored, the Free Companion Planting Chart for Vegetables: A Step-by-Step Guide (2026) walks through building a chart around your own crop list. For a layout-first approach, the Vegetable Garden Layout Companion Planting: A Step-by-Step Guide shows how to translate pairings into actual bed design.
Read the Chart and Build Your Planting Plan
Follow these steps to turn a chart into a bed plan:
- List every vegetable you intend to plant this season.
- Find each crop on the chart and note its good and bad neighbors.
- Sketch your beds on graph paper, using one square per 6 inches if you are planning a standard bed.
- Place tall crops such as corn or pole beans on the north side of the bed so they do not shade shorter plants.
- Keep incompatible pairs at least one bed or one full row apart.
- Check your spacing against the seed packet, since crowded plants undo most companion benefits.
Adjust the Chart for Your Garden
A chart written for one region may not match your climate. In cool northern gardens, you may need to stagger planting dates so that warm-season crops and cool-season crops do not compete for the same window. In hot, dry regions, pairings that rely on shade become more valuable, while those that increase water demand may need more space.
Keep a simple garden journal. Note what grew well beside what, and update your printed chart each year. Over two or three seasons, your personal notes will become more useful than any generic list.
Quick Reference Table
| Crop | Commonly Paired With | Commonly Kept Apart From |
|---|---|---|
| Tomato | Basil, carrots, marigolds | Potatoes, fennel |
| Beans | Corn, cucumbers, carrots | Onions, garlic |
| Cabbage family | Dill, onions, aromatic herbs | Strawberries, tomatoes |
| Squash | Corn, nasturtiums | Potatoes |
Common Mistakes
- Printing a chart without checking that it covers your specific varieties.
- Ignoring spacing, which often matters more than the pairing itself.
- Expecting companion planting to replace pest monitoring or good soil care.
- Planting a companion too late in the season to contribute anything useful.
- Assuming one chart applies unchanged to every climate and bed type.
Recommended Gear
A few basic supplies make a printed chart easier to use outdoors. A clipboard keeps your sheet dry and flat while you work, so you are not juggling paper in the wind. A plastic sheet protector lets you mark planting dates with a wipe-off marker and reuse the same chart each year. A simple garden journal gives you space to record which pairings performed well.
FAQ
Is a free printable companion planting chart reliable?
Charts from university extension offices or established gardening organizations are generally the most dependable. Treat any chart as a guide and confirm the advice against your own observations over time.
How far apart should companion plants be spaced?
Follow the spacing on the seed packet or plant tag for each crop. Companion benefits rarely offset overcrowding, so spacing should come first.
Can I use one chart for both containers and raised beds?
Yes, though containers have less room and less soil volume, so keep pairings to small, compatible plants. Reduce the number of crops per pot to avoid competition for water and nutrients.
Conclusion
A free printable companion planting chart for vegetables is most useful when you check it against your variety list, climate, and spacing needs. Print a reliable chart, sketch your beds, and record what works. Each season, your plan will get sharper and more tailored to your garden.
