Frequently Asked Questions
Can you plant Roma Tomato in a raised bed with companions?
Yes — raised beds are ideal for companion planting because you control exact spacing and layout. Use the square-foot method to place Roma Tomato alongside its best companions within the same bed.
How far apart should I plant Roma Tomato and its companions?
Give Roma Tomato its full 24" spacing. Plant compact companions like herbs 6–12" away at the bed edge, and taller companions (sunflowers, corn) where they won't shade the main crop. In raised beds, use the square-foot grid method for precise spacing.
Does companion planting actually work for Roma Tomato?
Research supports several companion planting mechanisms: aromatic herbs like basil can reduce aphid populations near tomatoes; marigolds release thiophene compounds that deter nematodes; and flowers attract parasitic wasps that control caterpillars. Results vary by garden, but most gardeners see measurable pest reduction within one season.
