Tomato companion plants

Tomato companion plants here are source-bound layout and named pairing contexts, not a universal chart. Extension sheets describe space, shade, and timing around tomatoes, then separately record rotation and disease-host planning. This page does not rank plants, promise pest control, yield, or flavor, or tell you what is “best.”

Cited tomato-specific rows with a visible Source field. Not a printable companion chart and not a spray plan. Time-separated rotation guidance is not coexistence advice.

Cited layout around tomatoes

Separate source assertions — not a BioArva average.

  • Source

    UMN Extension (Minnesota)
    This source describes planting lettuce, spinach, or basil early, then transplanting tomatoes (or peppers) into the same bed as that early crop matures. Tomato + lettuce/spinach/basil spatial succession — not a pest-control pairing, not basil-improves-flavor, and not a BioArva calendar.

  • Source

    Maryland Extension (Maryland)
    This source describes planting low-growing, shade-tolerant salad greens on the north side of tomatoes (also naming corn or eggplants). Tomato + salad greens shade arrangement — not a companion ranking.

  • Source

    WVU Extension (West Virginia)
    This source describes interplanting smaller cool-season plants such as spinach, beets, or lettuce in between larger, slow-growing vegetables such as tomatoes. Once the smaller crops mature, the larger plants’ canopy will offer shade. Tomato + spinach/beet/lettuce spatial/shade context — not a pest-control pairing and not a yield claim.

Cited tomato pairing contexts

Separate source assertions — not a BioArva average.

  • Source

    Maryland Extension (Maryland)
    This source describes planting peas at the base of tomato cages on the north side in early spring; when tomatoes go in later, the filled-in pea vines act as a wind shield. Tomato + pea spatial pairing — not pest-control or flavor.

  • Source

    Maryland Extension (Maryland)
    This source lists planting arrangement as alternate plants within a row, with basil-tomato-basil-tomato as the example. Tomato + basil spatial arrangement — not a flavor claim, not pest-control, and not a BioArva pairing rule.

Rotation and disease context

Separate source assertions — not a BioArva average.

  • Source

    Clemson Extension (South Carolina)
    This source says to choose a well-drained site where tomatoes, peppers, eggplant, or potatoes have not been grown for at least three years. Tomato + pepper/eggplant/potato rotation/site context — source-bound planning, not “never plant together” and not a diagnosis.

  • Source

    Clemson Extension (South Carolina)
    This source says tomatoes and related vegetables such as potatoes, peppers, and eggplants should not be planted on the same land more than once in three years. Tomato + potato/pepper/eggplant rotation context — source-bound planning, not “never plant together.”

  • Source

    Cornell (New York)
    This source says, to reduce root disease risk, don’t plant on soils that have recently grown tomatoes, potatoes, peppers or eggplant for at least two years. Tomato + potato/pepper/eggplant rotation context — source-bound planning, not coexistence advice.
  • This source groups eggplant, pepper, potato, tomato, tomatillo, ground cherry, and husk cherry in the nightshade family (Solanaceae) for rotation planning, and says gardeners should not plant vegetables belonging to the same plant family in the same location for 3 to 4 years (or 5+ if possible). Family-rotation planning — not a companion chart.

  • Source

    Clemson Extension (South Carolina)
    This source lists corn as a rotation crop with tomatoes. Tomato + corn rotation listing — not a beside-tomatoes pairing and not a control claim.

  • Source

    Clemson Extension (South Carolina)
    In southern blight management, this source says do not plant tomatoes after beans, pepper, or eggplant. Tomato + bean/pepper/eggplant rotation context for that disease on their sheet — source-bound planning, not “never plant together,” not a diagnosis, and not a pesticide path.

  • Source

    Clemson Extension (South Carolina)
    Because tomato pith necrosis affects other plants in the tomato family such as eggplants and peppers, this source says the site for the tomatoes should not be planted again with solanaceous plants for at least a year. Tomato + eggplant/pepper rotation context for that disease — not coexistence advice.

Black walnut / juglone siting (not a companion verdict)

Separate source assertions — not a BioArva average.

  • Source

    Penn State Extension (Pennsylvania)
    Vegetables in the solanaceous group, including tomatoes, peppers, and potatoes, are some of the least tolerant of juglone. Tomato named. Black-walnut/juglone siting context — not a companion verdict.

Plants that keep bugs away from tomatoes: what the cited rows establish

This page does not make a tomato companion recommendation to keep bugs away; the cited tomato-specific rows here do not establish one. For the separate, source-bound cross-crop evidence context, see companion planting.

Common pair questions

Where a cited tomato-specific row names both plants, the answer is that context — layout, pairing arrangement, or time-separated rotation — not a chart of plants that go together.

Can you plant tomatoes and peppers together?

Cited rows name tomato with pepper in rotation and disease-host planning (site gaps, same-family rest intervals, southern blight and pith-necrosis sections). That is time-separated guidance, not a coexistence verdict.

Can you plant cucumbers next to tomatoes?

This page has no cited tomato-specific row establishing a pairing or avoidance verdict for cucumber.

Can I plant zucchini next to tomatoes?

This page has no cited tomato-specific row establishing a pairing or avoidance verdict for zucchini.

Can you plant onions next to tomatoes?

This page has no cited tomato-specific row establishing a pairing or avoidance verdict for onion.

Can you plant tomatoes next to potatoes?

Cited rows name tomato with potato in rotation and disease-host planning (site gaps and same-family rest intervals). That is time-separated guidance, not a coexistence verdict.

Can you plant strawberries next to tomatoes?

This page has no cited tomato-specific row establishing a pairing or avoidance verdict for strawberry.

Can you plant beans next to tomatoes?

One cited row is Clemson southern blight management: do not plant tomatoes after beans, pepper, or eggplant. That is time-separated disease-section guidance, not a next-to pairing or a universal avoid list.

Can you plant squash next to tomatoes?

This page has no cited tomato-specific row establishing a pairing or avoidance verdict for squash.

Does basil grow well with tomatoes?

Cited tomato + basil rows are layout and in-row arrangement only — not a flavor claim and not a ranking of how well basil grows with tomatoes.

Can you plant corn next to tomatoes?

Clemson lists corn as a rotation crop with tomatoes. That is a rotation listing, not a beside-tomatoes pairing.

Can you plant carrots next to tomatoes?

This page has no cited tomato-specific row establishing a pairing or avoidance verdict for carrot.

Can you plant broccoli next to tomatoes?

This page has no cited tomato-specific row establishing a pairing or avoidance verdict for broccoli.

Can you plant eggplant next to tomatoes?

Cited rows name tomato with eggplant in rotation and disease-host planning. That is time-separated guidance, not a coexistence verdict.

Can you plant okra next to tomatoes?

Are marigolds good companion plants for tomatoes?

This page has no cited tomato-specific row establishing a pairing or avoidance verdict for marigold.

Can you plant lettuce next to tomatoes?

Cited layout rows describe lettuce (with spinach or basil) before tomatoes in the same bed, salad greens north of tomatoes, and lettuce between tomatoes with later canopy shade. Spatial/timing context — not a ranking.

Are nasturtiums good companion plants for tomatoes?

This page has no cited tomato-specific row establishing a pairing or avoidance verdict for nasturtium.

What should not be planted next to tomatoes?

This page does not publish a universal “do not plant next to tomatoes” list. Cited separation context is rotation and disease-host planning among named solanaceous crops, plus black-walnut/juglone siting. Those rows are time-separated or siting context — not coexistence advice.

What grows well with tomatoes in a raised garden bed?

This page does not publish a raised-bed pairing list. Cited layout contexts (succession, north-side greens, cool-season plants between tomatoes) are source-bound and do not name raised beds.

What is the best partner plant for tomatoes?

This page does not rank a “best” partner. Cited tomato pairing contexts are peas as a wind shield at tomato cages and basil-tomato as an in-row arrangement example — not a ranking.

What can I put around my tomato plants?

Cited layout around tomatoes: lettuce, spinach, or basil before tomatoes in the same bed; salad greens on the north side; spinach, beets, or lettuce between tomatoes with later canopy shade. Not a chart and not pest control.

What vegetables can be planted close to tomatoes?

This page does not publish a close-planting list. Use the cited layout and pairing contexts as planning options from those sheets — not a ranking of vegetables that grow well with tomatoes.

What can I plant in a container with tomatoes?

This page does not provide a tomato-container companion recommendation.

Can I plant peppers and tomatoes together?

This page does not give a coexistence verdict. Cited rows name tomato with pepper in rotation and disease-host planning (site gaps, same-family rest intervals, southern blight and pith-necrosis sections). That is time-separated guidance, not “plant them together.”
