A rosemary companion planting chart gives you a quick reference for which vegetables grow well beside rosemary and which ones to keep apart. This guide shows you how to read the pairings, space your plants correctly and build a simple chart for your own beds. By the end, you will know which vegetables benefit from rosemary’s strong scent and which ones need distance.

What a Rosemary Companion Planting Chart Shows

Most companion charts rate each pairing as beneficial, neutral or harmful. Rosemary is a woody perennial with a strong aromatic oil, and gardeners often plant it near crops that tolerate or benefit from that scent. The chart below reflects common guidance from extension-style sources, but results vary with soil, climate and bed size.

Vegetable Rating Notes
Cabbage family (broccoli, kale) Beneficial Rosemary’s scent is often said to deter cabbage moths.
Carrots Beneficial Rosemary is commonly paired with carrots to help confuse carrot fly.
Beans Beneficial Keep rosemary at the edge so it does not shade low-growing beans.
Sage Beneficial Both herbs prefer dry soil and similar sun.
Cucumbers Mixed Some gardeners report better results; see our cucumber pairing guide.
Potatoes Avoid Rosemary may reduce yields for some growers; keep them separate.
Basil Avoid Different water and root needs; basil tends to struggle beside rosemary.

How to Set Up Rosemary in Your Bed

Placement matters more than the pairing itself. Rosemary becomes a large shrub, so the layout you choose determines whether it helps or competes with nearby crops.

  1. Choose a corner or the north edge of your bed so the rosemary does not shade sun-loving vegetables.
  2. Space rosemary 24 to 36 inches from the nearest vegetable row. Mature plants can reach 3 to 4 feet tall and wide in warm climates.
  3. Plant in well-drained soil with a pH between 6.0 and 7.5. Add coarse sand or grit if your soil holds water.
  4. Water deeply but infrequently once established. Rosemary dislikes soggy roots, while nearby leafy crops usually need steady moisture.

Spacing Rules for Mixed Herb and Vegetable Beds

Rosemary’s roots spread wide and its canopy shades the ground. Treat it as a permanent anchor and plant annuals around it rather than directly against the stem. Leave a clear ring of at least 18 inches around the base for air movement, which also reduces fungal problems in humid weather.

Container Growing Adjustments

In containers, use a pot at least 14 inches wide for a single rosemary plant. Keep it on the sunniest side of the group so nearby vegetables are not shaded. Container pairings work best with beans, carrots and sage.

Common Mistakes to Avoid

  • Planting rosemary too close to potatoes or basil, which often leads to weaker growth.
  • Overwatering rosemary, the most common cause of root rot in home gardens.
  • Letting rosemary shade low crops like lettuce or carrots after it matures.
  • Treating the chart as a guarantee. Companion effects are often modest and hard to measure.
  • Forgetting to prune rosemary in spring, which keeps it compact and airy.

FAQ

Does rosemary really repel pests?

Rosemary’s scent may discourage some insects, such as cabbage moths and carrot flies. Results vary, so use it alongside row covers and regular inspection rather than as your only defense.

Can rosemary grow in the same bed as tomatoes?

Many gardeners plant them together, but tomatoes need more water than rosemary. Keep rosemary at the bed edge and avoid overwatering the area around its base.

How often should I update my companion planting chart?

Review it each season as you learn how your plants perform in your soil and climate. Your own notes are often more useful than any general chart.

Conclusion

A rosemary companion planting chart is most useful when paired with good spacing and careful watering. Plant rosemary at the bed edge, keep it away from potatoes and basil, and favor beans, carrots and cabbage-family crops nearby. Track your results each year and adjust your layout to fit your garden.
