Buying Guide: Key Considerations for Choosing Tomato Companion Plants

  • Pollinator support: Favor flowers like borage, calendula, and marigolds that attract bees and hoverflies, boosting pollination and natural pest control.
  • Herbs for flavor and pest deterrence: Basil, garlic, and oregano are widely reported to deter certain pests while adding culinary value to tomato dishes.
  • Plant spacing and growth habits: Choose companions with compatible sun, water, and space needs. Indeterminate tomatoes often benefit from taller flowering companions; determinate varieties may prefer low-growing allies.
  • Soil and nutrient balance: Keep soil rich but well-drained. Some companions, like basil in basil-tomato pairs, may benefit from similar nutrient requirements to simplify care.
  • Seasonal planning: Include both early- and late-season companions to maintain garden productivity across the growing season.
  • Package variety: For seeds, consider collections that combine multiple compatible plants to streamline planning and increase biodiversity in a single bed.
