No reviewed study supports a specific beneficial companion for raspberry yet. Keep it apart from Tomato because of shares disease risk. 1 popular pairing has no verified relationship, which is not the same as safe or harmful.
Every status below has a direction, mechanism, context and source. "No verified relationship" means we looked and found nothing usable; the planner then evaluates spacing, light, water and timing normally. How we classify evidence →
Avoid or separate (1)
Hard constraint only for serious, applicable conflicts; otherwise a weighted warning.
Avoid records need credible negative evidence or a clear cultural incompatibility. Hard constraints are marked in the Why? panel; the rest are weighted warnings with a remedy.
TomatoSolanum lycopersicumAvoidShares disease risk · Verticillium wilt Raspberry and Tomato affect each other (mutual)Summer · adjacent · Separate area.Tier C Review: August 15, 2026Why?
Claim. Raspberries share Verticillium wilt with nightshades; do not establish a raspberry row where tomatoes or potatoes grew recently.
Mechanism. Soil-borne pathogen.
Conditions. Planted together Separate area. Both plants must be present at the same time.
Management. Keep bed history.
Applies when. Bed-history concern for a permanent crop.
Limitations. Manageable.
Evidence. Tier C: Indirect evidence: greenhouse or pot work, a related crop or species, or credible extension guidance with important uncertainty. (extension synthesis).

No verified relationship (1)
Zero score and an honest unknown state. Spacing, light, water and timing are evaluated normally.
No verified relationship: we did not find a source that establishes a benefit or harm for these pairs. This is not the same as "compatible".

Example layout for raspberry
No supported or conditional relationship specifies a layout. Space raspberry at 45–60 cm and plan by light, water and timing.
Side view of raspberry (150–200 cm) beside typical companions, showing canopy, support, shade and access.
When these companions overlap
Bed occupancy in Portland, Oregon (estimates). A relationship only matters while both plants are present.

Crop rotation guidance
Rotation is about what occupied the bed in previous seasons and is calculated separately from the live companion relationships above.
Raspberry is a permanent planting and is not rotated.
No significant light, water, pH or sprawl conflicts with the listed companions at recommended spacing.
Fit checks come from plant attributes and apply even when a pairing has a positive claim.
Community observations (anecdotal)
These reports come from gardeners and are not reviewed evidence. Results vary with soil, climate and practice. Community data never changes an evidence tier or a planner score.
Reports for raspberry: 0 (community submissions open in a later phase; drafts are stored only on your device).

Reviewer: Garden Planner editorial team (pending independent horticultural review). Status counts on the Companions A–Z page are derived from these records. Corrections.
Documentary and illustrated views distinguish identification, measured layout, seasonal overlap, mechanisms, coexistence examples, and community observations. Captions state what each visual can and cannot establish.
Our Methodology & Sources
We synthesize peer-reviewed research, university extension publications, and trusted horticulture resources. Our evidence levels help you understand how strong the science is behind the guidance.
