A tomato guild starts with the tomato as the anchor crop. From there, we add support plants that help the whole bed function better. The goal is not to plant everything. The goal is to choose a few plants where each have a job in the ecosystem. A simple tomato guild might include: Main crop:Tomato Aromatic plants for pest confusion: Basil, chives, onions, leeks, thyme, oregano, marigold Soil cover: Lettuce, spinach, parsley, nasturtium, straw mulch, leaf mulch, compost with hardwood mulch; living mulch like clover Pollinator and beneficial insect plants: Parsley flowers, yarrow, zinnia, marigold, calendula, nasturtium Different root zones: Onions, chives, leeks, lettuce, parsley, basil, radish, carrots if space allows Soil life support: Compost, vermicompost, chopped leaves, straw, leaf mold, comfrey chop-and-drop, fall cover crop This gives us food, scent confusion, soil cover, insect support, root diversity, and soil protection. A guild is not a magic formula. It is a way to stop seeing each plant as separate and start seeing the bed as a small living system.
