Companion Planting Hints: What the Notes Mean

Select a plant in the workspace and the inspector may show one or both of these panels, based on what else is in the same bed:

• Amber — "Avoid in this bed": the two plants are documented antagonists. Each name comes with a short note on why to keep them apart.
• Green — "Good neighbor in this bed": a documented beneficial pairing.

Click a neighbor's name in either panel to select that plant on the canvas.

Where the data comes from

GardenDraft's companion data isn't folk-chart lore. Each relationship is backed by cited sources — university extension services, USDA, and peer-reviewed studies — and graded by evidence tier: A (peer-reviewed with a clear mechanism), B (consensus across extension services), C (traditional practice with a plausible mechanism).

To read why a pairing helps or hurts — the mechanism, sources, and any regional or timing notes — open either plant's page in the plant database.

What to do about a warning

Hints are advisory; nothing blocks you from planting antagonists together. Effects are usually modest, so treat warnings as a tiebreaker when deciding where something goes — moving one plant to a different bed clears the note. See How to place, move, and space plants.
