Somewhere along the way, companion planting got a reputation as garden astrology. “Plant your tomatoes under a waxing moon next to basil that was whispered compliments at dawn.” Look — some companion planting advice absolutely is folk wisdom wearing a lab coat it found in a dumpster. But some of it is genuinely, measurably real, backed by actual entomologists who wear actual lab coats.
This guide is the honest version. We’ll tell you which pairings have science behind them, which ones are tradition with a shrug, and which plant combos are basically a reality TV feud waiting to happen. Because the goal isn’t superstition — it’s designing beds that function like ecosystems instead of plant storage units.
Fair warning: no pairing on earth outperforms healthy soil. A tomato in living, microbe-rich soil will shrug off problems that would flatten the same tomato in dead dirt, no matter how much basil you plant next to it. Think of companion planting as the supporting cast. The soil is the main character. (Worm castings are the main character’s extremely competent agent. Just saying.)
🤔 WHAT COMPANION PLANTING ACTUALLY IS (AND WHAT IT ISN’T)
Strip away the mystique and companion planting is just this: growing specific plants near each other on purpose, because the combination performs better than either plant alone. That’s it. No moon phases required. Indigenous farmers figured out the greatest hits centuries before anyone wrote a gardening book — the Three Sisters (corn, beans, squash) is companion planting with a few thousand years of field testing behind it.
When it works, it works through a handful of real mechanisms. Understanding the mechanisms matters, because it lets you improvise instead of memorizing charts:
- Pest confusion. Many pests find their host plants by smell. Interplanting a strongly scented crop (onions, garlic, herbs) among a vulnerable one (carrots) can scramble the signal. The carrot fly (Psila rosae) literally navigates by carrot scent — muddy that signal with onion odor and fewer flies find the target. It’s not magic; it’s olfactory camouflage.
- Trap cropping. Some plants are so delicious to pests that bugs will choose them over your crops. Nasturtiums are an aphid nightclub — plant them nearby and aphids party there instead of on your cucumbers. Radishes lure flea beetles away from slower brassicas. You’re not preventing pests; you’re giving them a designated dance floor.
- Nutrient sharing. Legumes (beans, peas) partner with Rhizobium bacteria to fix atmospheric nitrogen into the soil. Some of that nitrogen becomes available to neighbors. It’s real, though slower and less dramatic than fertilizer companies would have you fear — the big payoff comes when the bean roots decompose, so chop-and-drop spent bean plants instead of yanking them.
- Shade and physical support. Corn stalks are free trellises for pole beans. Tall sunflowers or trellised cucumbers cast afternoon shade that keeps lettuce from bolting into a bitter skyscraper. In Florida, where the sun has personal vendettas, shade is a legitimate crop input.
- Pollinator and predator attraction. Flowers interplanted with vegetables summon two workforces: pollinators (more bees = more squash, cucumbers, and melons actually setting fruit) and beneficial predators (ladybugs, lacewings, hoverflies, and parasitoid wasps that treat aphids and caterpillars like a buffet). A vegetable bed with no flowers is a restaurant with no customers.
And when it doesn’t work? Usually because the advice was vibes-based. “Basil improves tomato flavor” is the classic — it sounds lovely, there is essentially no evidence for it, and yet it appears in every companion planting chart ever printed. (Basil and tomatoes are still great neighbors — basil’s flowers feed beneficial insects, and harvesting them together is convenient. The flavor claim is just unproven garnish.)
Guild Builder Tip: When you read a pairing claim, ask “what’s the mechanism?” If nobody can name one — not even a plausible one — it’s probably tradition, not science. Tradition is fine! Just don’t bet the whole bed on it.
⭐ THE ALL-STARS: PAIRINGS THAT EARNED THEIR REPUTATION
These are the pairings with the best combination of scientific support, centuries of farmer observation, and “yeah, that actually worked in my garden” energy. Start here.
🌽 The Three Sisters: Corn + Pole Beans + Squash
The undisputed heavyweight champion of companion planting, developed by Indigenous peoples of the Americas and field-tested for millennia. Each sister does a job: corn provides a living trellis, pole beans climb the corn and fix nitrogen via their Rhizobium partners, and squash sprawls underneath, shading the soil (fewer weeds, less evaporation) while its prickly stems discourage raccoons and other four-legged critics.
To do it right: plant corn first in a block (not a single row — corn is wind-pollinated and lonely corn makes sad, half-filled ears), let it reach about a foot tall, then plant pole beans (not bush beans — they won’t climb) at the base, then squash around the perimeter. Timing matters: beans planted too early can yank young corn over like a tiny green wrestler.
Guild Builder Tip: Florida gardeners — run your Three Sisters in early spring or fall, not the brutal summer. Corn in July heat with no rain is just expensive bird food. Sweet potatoes make an excellent summer “fourth sister” sprawling underneath instead of squash.
🍅 The Famous Couples
- Tomatoes + basil. The celebrity couple. Honest assessment: basil does not measurably improve tomato flavor (sorry, every garden blog). What it does do is attract pollinators and beneficial insects when allowed to flower, and the two crops want the same sun, water, and harvest schedule — which makes them logistically perfect roommates. Plant basil 8–12 inches from tomato stems and let at least one basil plant flower for the beneficials.
- Tomatoes + borage. Borage (Borago officinalis) is a pollinator magnet with star-shaped blue flowers that bees lose their minds over. More bee visits = better pollination for everything nearby. Tradition also claims borage improves tomato growth and flavor — the pollinator part is solid, the rest is garnish. Bonus: borage flowers are edible and taste faintly like cucumber.
- Tomatoes + marigolds (French). This one’s genuinely earned. French marigolds (Tagetes patula — not the big African ones, specifically French) suppress root-knot nematodes (Meloidogyne spp.) through compounds released by their roots. In Florida’s sandy soils, where nematodes throw pool parties year-round, this is a big deal. Research shows the effect is real but requires commitment: grow the marigolds densely for a full season, ideally tilling them in at the end. A single marigold waving bravely between two tomatoes helps a little; a solid border helps a lot.
- Tomatoes + carrots. Carrots are the ideal tomato understory — shallow-rooted, undemanding, and finished before tomatoes get huge. They use different soil layers (tomatoes root deep, carrots stay shallow), so they’re not really competing. Sow carrots around tomato transplants in early spring.
🥕 The Root Crew
- Carrots + onions (or garlic, chives, leeks). The carrot fly finds carrots by smell; the onion’s pungent sulfur compounds jam the signal. Interplanting rows of onions with carrots measurably reduces carrot fly damage in trials — this is one of the better-supported scent-confusion pairings. As a bonus, carrots and onions occupy different root zones and mature on compatible timelines. In Florida, run this pairing in fall through spring; carrots despise summer.
- Radishes + cucumbers (or squash). Flea beetles adore radishes the way gardeners adore spring — which makes radishes an excellent sacrificial trap crop. Sow radishes a week or two before your cucumbers; the beetles mob the radishes first. Radishes also germinate fast and mark rows for slower crops. The radishes may look like lace doilies by the end. That’s them doing their job. Salute them.
- Garlic + roses and fruit trees. Old rose-grower tradition with some legs: garlic’s sulfur compounds appear to deter aphids and other soft-bodied pests, and interplanted garlic has shown mild protective effects in orchard trials. Plant garlic cloves around the drip line of fruit trees or at the base of roses in fall. Worst case, you grew garlic, which is never a bad outcome.
🥒 The Vine Squad
- Cucumbers + nasturtiums. Nasturtiums (Tropaeolum majus) are the ultimate trap crop — aphids find them irresistible and will colonize nasturtiums while largely ignoring nearby cucumbers. Plant nasturtiums at the ends of cucumber rows or spilling from adjacent containers. Bonus: nasturtium flowers and leaves are edible with a peppery bite, so your trap crop doubles as salad.
- Cucumbers + dill. Dill attracts hoverflies, ladybugs, and parasitoid wasps — the beneficial-insect cavalry. Let some dill flower near (not in) the cucumber patch. Just keep dill away from carrots (both are Apiaceae family; they cross-pollinate and share pests — more on feuds below).
- Cucumbers + sunflowers. Mammoth sunflowers make sturdy living trellises for lightweight cucumber varieties, and their giant flower heads are pollinator airports. Plant sunflowers on the north side so they don’t shade the cukes, and give the sunflowers a two-week head start.
🥬 The Shade Seekers
- Lettuce + tall plants (tomatoes, trellised beans, corn, sunflowers). Lettuce bolts — turns bitter and flowers — when it’s hot and stressed. In Florida, “hot and stressed” describes roughly February through November. Planting lettuce on the east or north side of taller crops gives it afternoon shade, buying you weeks of extra harvest. This is pure physics, no mysticism: cooler leaves, slower bolting.
- Spinach + strawberries. Low-growing spinach makes a living mulch under strawberries, shading soil and suppressing weeds without competing for root space. Both appreciate consistent moisture. Harvest the spinach before strawberry season peaks and you’ve double-cropped the same square footage.
🫘 The Brassica Bodyguards
- Dill + brassicas (cabbage, kale, broccoli, collards). Flowering dill is a parasitoid wasp magnet, and parasitoid wasps are the stuff of cabbage-worm nightmares — they lay eggs inside caterpillars, which is horrifying and extremely effective. Interplant dill among brassicas and let it bloom. (Repeat after us: keep it away from carrots.)
- Brassicas + onions/garlic. Alliums’ scent appears to confuse cabbage moths and flea beetles looking for brassica hosts. The evidence is moderate but the pairing costs nothing — tuck onion sets or garlic around brassica transplants. In Florida, grow this combo fall through early spring; brassicas melt in summer.
- Chamomile + everything (especially brassicas). Chamomile carries the folk title “plant’s physician” — the tradition says it improves the health of neighbors. The science is thin, but chamomile’s tiny daisy flowers genuinely attract hoverflies and beneficial wasps, so the mechanism (more beneficial insects) is real even if the mystique isn’t. It’s also just delightful. Sometimes that’s enough.
Guild Builder Tip: Notice a pattern? The strongest pairings all have a named mechanism — scent confusion, trap cropping, nitrogen fixation, shade, predator habitat. When you’re designing your own combos, steal mechanisms, not just plant names.
⚔️ THE FEUDS: PLANTS TO KEEP APART
Companion planting has an evil twin: antagonistic planting. Some plants genuinely sabotage each other — through shared pests, chemical warfare (allelopathy), or just incompatible demands. These are the breakups you want to arrange deliberately.
- Onions & garlic vs. beans & peas. Alliums (onions, garlic, shallots, leeks) release sulfur compounds that inhibit the growth of legumes and can interfere with the nitrogen-fixing bacteria beans and peas depend on. The result: stunted, sulky legumes. Keep alliums and legumes in separate beds, or at least several feet apart. This is one of the most consistently reported antagonisms in gardening literature — respect it.
- Tomatoes vs. corn. Plot twist: the corn earworm and the tomato fruitworm are the same insect (Helicoverpa zea) — just wearing different hats depending on which crop it’s ruining. Planting corn next to tomatoes is essentially building a pest duplex with shared walls. Give them distance. (Note the irony: corn and beans are best friends, beans and tomatoes are fine, but corn and tomatoes need couples counseling. Plant families are complicated.)
- Fennel vs. everything. Fennel (Foeniculum vulgare) is allelopathic — its roots exude compounds that inhibit germination and growth in neighboring plants. It’s not being rude; it’s chemical warfare as a lifestyle. The solution is simple: give fennel its own container or a lonely corner of the garden where it can be a beautiful, feathery misanthrope in peace. (Dill is sometimes accused of the same, but dill’s rap sheet is mostly about cross-pollinating with carrots and fennel, not poisoning neighbors.)
- Potatoes vs. tomatoes. Both are Solanaceae (nightshades), which means they share the same worst enemies — most notably late blight (Phytophthora infestans), the pathogen behind the Irish Potato Famine, plus early blight and several viruses. Growing them side by side is throwing a blight party and inviting all the spores. Rotate them away from each other and never follow one with the other in the same soil.
- Dill vs. carrots. Both are Apiaceae (the carrot family), so they cross-pollinate enthusiastically — which matters if you save seed — and they share pests like the carrot fly. Mature dill can also stunt young carrot growth. Keep flowering dill near your brassicas and cucumbers, far from your carrot rows.
- Sunflowers vs. young/small plants (use with caution). Sunflowers produce allelopathic compounds from roots and decaying residue that can suppress germination and growth of some neighbors — it’s how they dominate a patch in the wild. Established, vigorous companions (like trellised cucumbers or pole beans climbing the stalk) do fine, but don’t sow tiny seeds in the shadow of a sunflower and expect gratitude. Chop sunflower stalks at season’s end rather than tilling masses of residue straight into beds you’ll plant immediately.
Guild Builder Tip: Most feuds come down to two causes: shared pests/diseases (same plant family = same enemies) or chemical inhibition (allelopathy). If two plants are in the same family, default to separating them unless you know a specific reason they’re fine together.
🌸 FLOWER ALLIES: THE HARDEST-WORKING PLANTS IN THE GARDEN
If companion planting has one universal rule, it’s this: interplant flowers with your vegetables. Flowers recruit pollinators (fruit set!), summon predatory insects (pest control!), and make the whole bed look like you know what you’re doing. These are the MVPs:
- Marigolds (French, Tagetes patula). The nematode suppressors. Dense plantings reduce root-knot nematode populations — a genuine superpower in Florida’s sandy soils. They also repel some above-ground pests with their pungent foliage. Deadhead for continuous bloom. Remember: French marigolds for nematodes; the giant African/Aztec types (T. erecta) are showier but less proven for the nematode job.
- Nasturtiums (Tropaeolum majus). The sacrificial trap crop — aphids, flea beetles, and squash bugs all prefer nasturtiums to your vegetables. Let them sprawl at bed edges and ends of rows. Edible flowers and leaves with a wasabi-adjacent kick. They also reportedly deter squash bugs when planted near squash, though the evidence there is more “enthusiastic tradition” than “peer-reviewed.”
- Calendula (Calendula officinalis). Blooms nearly year-round in mild climates, feeds hoverflies and other beneficials all season, and its sticky foliage reportedly traps aphids. Edible petals for salads, medicinal uses for skin — the overachiever of the flower world. Self-sows freely; once you plant it, you’ve made a long-term commitment.
- Borage (Borago officinalis). Blue star-shaped flowers that bees visit obsessively — one of the highest nectar producers among common garden flowers. Excellent near anything that needs pollinators: squash, cucumbers, strawberries, tomatoes. Self-sows enthusiastically. The fuzzy leaves are technically edible but feel like licking a sweater; stick to the flowers.
- Sweet alyssum (Lobularia maritima). Tiny white (or purple) flowers, enormous beneficial-insect value. Alyssum is one of the best-documented insectary plants — its shallow flowers feed hoverflies and parasitoid wasps that larger blooms can’t serve. Plant it as a low edging around vegetable beds. It tolerates Florida heat better than its delicate looks suggest and blooms nearly year-round.
- Dill (allowed to flower). Once dill bolts and blooms, its umbrella-shaped flower heads become landing pads for ladybugs, hoverflies, lacewings, and parasitoid wasps. Stop fighting the bolt — plan for it. Sow dill every few weeks so there’s always some in flower near your brassicas and cucumbers.
- Cilantro/coriander (allowed to flower). Same story as dill — another Apiaceae whose flowers feed the beneficial-insect hordes. In Florida, cilantro bolts approximately four seconds after you plant it (it hates heat), so lean into it: let it flower, harvest the coriander seeds, and let the volunteers feed your wasps.
- Sunflowers (Helianthus annuus). Living trellises for pole beans and light cucumbers, plus massive pollinator waystations. Plant on the north side of beds, give them a head start, and choose sturdy varieties if anything will climb them. At season’s end, the seed heads feed birds — leave a few standing and enjoy the show.
Guild Builder Tip: Aim for something in flower in or near the vegetable garden every week of the growing season. In Florida, that’s nearly year-round — alyssum, calendula, and nasturtiums can carry the winter shift while borage and sunflowers handle summer. Continuous bloom = continuous beneficial-insect employment.
🗺️ DESIGNING A COMPANION-PLANTED BED: A WORKED EXAMPLE
Theory is nice. Let’s build something. Here’s a complete 4×8-foot bed designed as a working ecosystem — every plant has neighbors chosen for a reason. Walk through it once and you’ll be able to design your own.
📐 The Layout (4 feet wide × 8 feet long, long axis running east–west)
The north edge (the back of the stage): Run a 6-foot trellis along the north side of the bed — north so it never shades the rest. Plant pole beans at its base (they’ll climb the trellis and fix nitrogen), and at one end of the trellis, plant cucumbers to scramble up alongside. Tuck flowering dill at the trellis ends — its blooms will feed the wasps and hoverflies patrolling the whole bed.
The middle band (the main cast): Two tomato transplants go in the center, spaced about 3 feet apart and staked or caged. Between and around them, plant basil — one per tomato, plus one you’re allowed to let flower for the pollinators. Ring the tomatoes with French marigolds, spaced about a foot apart; this is your nematode-suppression border doing quiet underground work all season. A borage plant at each end of the tomato row adds pollinator firepower.
The south edge (the front row): This is the low-growing zone. A row of carrots runs along the front, interplanted with onion sets every 6 inches — the onions jam carrot-fly radar while the carrots fill the understory. In front of the carrots, a drift of sweet alyssum spills over the bed edge, feeding beneficial insects at ground level. At the two front corners, plant nasturtiums and let them cascade — they’re the aphid trap crop, positioned as far from the tomatoes as the bed allows.
The understory (between everything): Sow radishes thickly in any gaps in early spring — they’ll be harvested (or sacrificed to flea beetles) long before the tomatoes need the space. As the season warms, tuck lettuce transplants on the east side of the tomato cages, where they’ll catch morning sun but hide from brutal afternoon rays behind the tomato foliage.
Count the mechanisms at work: nitrogen fixation (beans), trap cropping (nasturtiums, radishes), scent confusion (onions with carrots), nematode suppression (French marigolds), pollinator recruitment (borage, dill, alyssum), shade management (tomatoes sheltering lettuce), and vertical stacking (trellis beans and cucumbers above, carrots below). That’s eight ecosystem functions in 32 square feet. A monoculture bed the same size does exactly one: grow the thing.
🔄 Succession Notes: Keep the Bed Working All Season
- Early spring: Radishes, carrots, onions, and lettuce go in first — they’re cold-tolerant and fast. The trellis, tomatoes, and basil wait until after the last frost.
- As spring warms: Transplant tomatoes and basil, direct-sow beans and cucumbers at the trellis, and set out marigold and nasturtium transplants. The radishes come out (eaten or beetle-mauled) just as the warm-season crew needs elbow room.
- Summer: In Florida, this bed’s cool-season players (lettuce, carrots) are done. Replace the lettuce zone with heat-lovers: a pepper transplant or okra tucked where the lettuce was, still benefiting from tomato shade. Let the basil, marigolds, and borage carry the flower shift.
- Fall reset: Pull spent tomatoes and beans — but chop and drop the bean plants, leaving roots in the soil so the nitrogen nodules decompose in place. Till the French marigolds into the bed (this maximizes their nematode-suppressing effect), then plant fall carrots, onions, and brassicas with fresh dill for the wasp patrol.
- The golden rule of succession: never leave soil bare. Bare soil is an invitation to weeds, erosion, and nematodes. If a crop comes out and nothing’s ready to go in, sow a quick cover — buckwheat in warm weather, crimson clover in cool — or just mulch heavily. Nature abhors a vacuum and fills it with weeds.
Guild Builder Tip: Sketch your bed on paper before planting season, then keep the sketch and scribble what actually happened. After two seasons you’ll have a custom companion-planting guide for your exact soil, sun, and pest pressure — which beats any chart on the internet, including this one.
📋 QUICK-REFERENCE: FRIENDS & FOES BY CROP
The cheat sheet. Tape it to the shed wall.
🍅 Tomatoes
Love: basil, borage, carrots, marigolds (French), onions, garlic, lettuce (as shaded understory), nasturtiums (as trap crop at a distance). Hate: corn (shared earworm/fruitworm pest), potatoes (shared blight), fennel (allelopathic). Florida note: cherry types handle heat and nematodes better than big slicers; always mulch heavily.
🫑 Peppers
Love: basil, onions, garlic, marigolds, carrots (understory), alyssum nearby for beneficials. Hate: fennel, and keep away from beans if space allows (they compete more than they cooperate). Florida note: peppers are perennials here if you protect them from the rare freeze — a two-year-old pepper plant is a beautiful thing.
🥒 Cucumbers
Love: nasturtiums (aphid trap crop), dill (beneficial wasps), radishes (flea beetle trap crop), sunflowers or corn as living trellis, marigolds. Hate: aromatic herbs like sage planted right on top of them (they can stunt cucumber growth — give sage its own corner). Florida note: trellis everything; ground-level cucumbers in humid Florida are a fungal disease waiting to happen.
🎃 Squash (Summer & Winter)
Love: corn and pole beans (the Three Sisters), nasturtiums (squash bug trap crop — enthusiastic tradition, plausible mechanism), borage and dill nearby for pollinators (squash needs bees; no bees, no squash), radishes. Hate: potatoes nearby (compete heavily and share some pests). Florida note: squash vine borers are the arch-nemesis — succession-plant every 3–4 weeks so borers can’t take the whole crop at once.
🥕 Carrots
Love: onions, garlic, chives, leeks (scent confusion vs. carrot fly), tomatoes (compatible understory), radishes (mark the row — radishes sprout fast and show you where the slow carrots are). Hate: dill (cross-pollination + shared pests), parsnips planted densely nearby (they share pests too — give them room). Florida note: fall-through-spring crop only; sow into loose, deep, rock-free soil or accept abstract-art carrots.
🫘 Beans (Bush & Pole)
Love: corn (living trellis — pole beans), squash (living mulch), carrots, cucumbers, marigolds, rosemary nearby (reportedly deters bean beetles). Hate: onions, garlic, shallots, leeks (alliums stunt legumes and their nitrogen-fixing bacteria). Florida note: inoculate seeds with Rhizobium bacteria the first time you plant beans in a bed — Florida’s sandy soils may not have the right strains waiting.
🥬 Brassicas (Cabbage, Kale, Broccoli, Collards)
Love: dill (parasitoid wasps vs. cabbage worms), onions and garlic (confuse cabbage moths), chamomile, nasturtiums (trap crop for aphids), marigolds. Hate: strawberries nearby is traditional advice but weakly supported — the real rule is don’t follow brassicas with brassicas (clubroot and shared pests build up). Florida note: strictly a fall-through-spring crop; collards are the heat-toughest of the bunch.
🥗 Lettuce & Greens
Love: tall crops for afternoon shade (tomatoes, trellised beans, corn), carrots and radishes (compatible roots), onions, strawberries (living mulch pairing). Hate: nothing dramatic — lettuce is the easygoing friend. Just don’t plant it in full Florida sun and act surprised when it bolts. Florida note: grow lettuce October through March; in summer, switch to heat-tolerant greens like Malabar spinach, longevity spinach, or sweet potato leaves.
🧅 Onions & Garlic
Love: carrots (the classic), brassicas, tomatoes, peppers, roses, fruit trees, strawberries. Basically everything except… Hate: beans and peas (stunted by allium compounds). Onions are the extroverts of the garden — welcome almost everywhere, feuding only with legumes.
🌽 Corn
Love: pole beans and squash (the Three Sisters), cucumbers (use the stalks as trellis), marigolds at the base. Hate: tomatoes (the earworm/fruitworm is one insect with two names). Florida note: plant in blocks for wind pollination, and in Florida’s summer storms, choose shorter, sturdy varieties unless you enjoy corn-kabob performance art.
🍓 Strawberries
Love: borage (pollinators + tradition), spinach or lettuce as living mulch, onions and garlic nearby (pest confusion), thyme as a low groundcover between plants. Hate: don’t plant where tomatoes, potatoes, or peppers grew recently (shared verticillium wilt risk — all Solanaceae). Florida note: in Florida, strawberries are an annual fall-planted crop (plant in October, harvest through spring), not the perennial patch northern gardeners know.
🌱 THE HONEST TAKEAWAY
Here’s the truth, delivered with love: companion planting is real, useful, and genuinely fun — and it is not the most important thing in your garden. The hierarchy goes like this:
- Healthy, living soil beats every pairing chart ever printed. A plant in biologically active soil resists pests, tolerates stress, and outgrows problems. A plant in dead dirt struggles no matter who its neighbors are. Feed the soil first — compost, mulch, worm castings, the whole program.
- Right plant, right place, right season comes second. A tomato planted in October in Florida will outperform a perfectly companion-planted tomato set out in July. Timing and placement are the unsexy superpowers.
- Flowers among the vegetables comes third — and it’s the single highest-value companion planting move. If you do nothing else from this guide, interplant flowers. Pollinators, predators, beauty. Done.
- Specific pairings and feuds come fourth. Worth knowing, fun to design around, genuinely helpful at the margins — the Three Sisters, the marigold-nematode trick, keeping alliums away from beans. These are real edges. They’re just edges, not foundations.
So design your beds like ecosystems, plant your flowers with your food, keep the feuding families apart — and then spend most of your energy on the soil, because the soil is doing 90% of the work while the companion planting takes the credit. The soil doesn’t mind. The soil is humble like that.
Now go introduce your tomatoes to some basil. They’ve been waiting to meet.
