Dill is a fussy garden partner — it attracts swallowtail caterpillars, repels aphids from some neighbors, but also bolts when crowded by the wrong herbs. Getting the mix right means healthier soil, fewer pests, and a longer harvest window for your feathery fronds.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. I spend my time cross-referencing horticultural trial data, owner reviews, and seed germination reports to build actionable pairing guides that save gardeners from crop failure.
This article distills the research into five proven options so you can confidently plant a productive dill bed. After analyzing dozens of seed packets and companion-planting references, I’ve assembled a tight list of the best companion plants for dill that actually deliver on pest control and growth synergy.
How To Choose The Best Companion Plants For Dill
Dill is shallow-rooted and grows fast, so the right neighbors won’t compete for water or shade the stems. Focus on plants with similar sun needs (full to partial), medium moisture requirements, and the ability to attract predatory wasps or repel cabbage loopers. Avoid fennel and carrots — they cross-pollinate with dill and reduce seed viability.
Growth habit compatibility
Dill reaches two to four feet tall with a feathery crown. Pair it with low-growing spreaders like nasturtium or chamomile that cover soil without blocking light. Avoid tall, dense plants like corn or sunflowers that shade dill’s base and trigger early bolting.
Pest management role
Dill is a powerhouse for attracting beneficial insects — braconid wasps, lacewings, and hoverflies all visit its umbels. Pair it with plants that repel aphids (like chives or cilantro) or act as trap crops (nasturtium draws aphids away). The combination reduces chemical sprays and creates a self-regulating microclimate.
Harvest timing overlap
Dill goes to seed in about 60–70 days. Fast-growing companions like basil (50–60 days) or oregano (perennial) provide ground cover without requiring simultaneous replanting. Avoid long-season brassicas like broccoli that may still be maturing when dill senesces, leaving bare soil prone to weeds.

In‑Depth Reviews
1. Burpee Culinary Classics Garden Collection
This Burpee collection packs ten herb packets — basil, chives, cilantro, sage, thyme, dill, parsley, chamomile, marjoram, and oregano — letting you plant dill alongside proven companions like basil and chives in one purchase. The non-GMO seeds boast 35% higher germination than industry benchmarks, so you avoid the frustration of bare soil where dill companions should be growing.
Users report robust initial growth and clear instructions, with several noting the fresh chamomile works as a low-growing ground cover under dill’s tall umbels. The loam soil recommendation matches dill’s preference for well-drained, moderately rich beds. Indoors or out, the seeds sprout consistently within the first week.
For gardeners who want a complete companion system without hunting individual packets, this kit delivers every aromatic partner dill benefits from — basil repels thrips, chives deter aphids, and dill itself attracts predatory wasps to protect the entire bed.
What works
- High germination rates reduce replanting headaches
- Includes every top dill companion in one box
What doesn’t
- Some users note occasional seeds fail to sprout
- Organic certification not listed on all varieties
2. Nasturtium Seeds – Mixed Colors – Bulk Quarter Pound Bag
Nasturtium is the single best trap crop for dill — its broad leaves and colorful blooms attract aphids away from dill’s tender stems, while its sprawling habit keeps soil cool and moist around dill’s shallow roots. This quarter-pound bag contains over 900 open-pollinated seeds, enough to border an 80-square-foot dill bed.
Buyers consistently praise the near-100% germination after an overnight soak, with seedlings appearing within a week even in tough conditions like Phoenix heat or Colorado mountains at 8,400 feet. The mixed colors (orange, red, yellow) add aesthetic value while serving a functional pest-diversion role.
Because nasturtium is edible — peppery leaves and flowers — it also extends your kitchen harvest. Plant it as a perimeter around your dill patch, let it trail over edges, and watch the aphid population collapse as ladybugs follow the trap crop instead of your herbs.
What works
- Massive quantity covers large beds without reseeding
- Excelent germination after simple overnight soak
What doesn’t
- Can become leggy in fertilized potting soil
- Requires thinning to avoid overcrowding
3. The Complete Guide to Companion Planting (Revised 2nd Edition)
This 288-page reference dives deep into the plant relationships that matter for dill — which herbs share its root zone without competition, which flowers repel the pests that target umbellifers, and why dill and fennel should never share a bed. It covers nitrogen-fixing companions (beans, peas) that enrich soil dill depletes mid-season.
Readers call it a “homesteading game-changer” and praise its readable style, though some note minor errors about plant nutrient needs and missing warnings about aggressive spreaders like lemon balm. Still, the companion-planting charts alone justify shelf space for any dill grower planning a polyculture bed.
If you’re serious about understanding the allelopathic interactions that make or break a dill patch, this book provides the scientific framework behind the pairing recommendations — far more depth than a quick web search.
What works
- Extensive cross-referenced charts for quick lookups
- Covers both pest-repellent and soil-enrichment pairings
What doesn’t
- Contains a few factual errors on nutrient roles
- Omits warning about lemon balm’s aggressive spread
4. Culinary Herb Seeds Garden Collection (Mountain Valley Seed Company)
This six-packet selection — dill, basil, oregano, parsley, chives, and mustard — provides the core aromatics that synergize with dill in the garden and kitchen. Basil repels thrips, chives deter aphids, and oregano acts as a living mulch that suppresses weeds around dill’s base. All seeds are non-GMO and open-pollinated.
Reviewers highlight dill’s fast germination (as quick as four days under a heat mat) and vigorous seedling growth. The basil and sage varieties performed especially well for most growers. A few users reported spotty germination on select varieties, but overall the pack offers excellent cost efficiency for building a companion guild.
The packaging — a small cardboard box rather than plastic — is a practical bonus for eco-conscious gardeners. Pair this with a bag of nasturtium seeds for a near-complete dill ecosystem in a single shopping cart.
What works
- Dill germinates in 4–7 days with basic heat mat
- Compact cardboard packaging reduces plastic waste
What doesn’t
- Some seed varieties have inconsistent germination rates
- Up to two substitutions possible due to seasonal availability
5. Basic Companion Planting for Successful Vegetable Gardening (Bruce’s Basic Garden Guides)
This beginner-focused guide strips companion-planting theory down to actionable pairings and clear charts — perfect if you’re starting your first dill bed and want to know immediately what to plant nearby without wading through complex botany. It covers organic pest control, soil building, and raised-bed planning specific to dill’s shallow root system.
Readers praise the “easy-to-follow” tone and light humor that makes it a quick read. The book explains why dill attracts beneficial insects like braconid wasps and which vegetables (cabbage family, corn) should stay far away. A few buyers noted smeared ink on certain pages, so inspect your copy upon arrival.
If you’re a visual learner who wants companion-planting wisdom you can apply in a single weekend, this book delivers the framework without overwhelming detail. Pair it with a seed packet set to start your dill garden immediately.
What works
- Engaging, non-technical writing for absolute beginners
- Step-by-step garden planning from ground prep to harvest
What doesn’t
- Some copies have printer ink smearing on key pages
- Limited depth on advanced allelopathy interactions
Hardware & Specs Guide
Seed Packet Count
The number of individual seed packets in a companion set directly determines how many beneficial planting combinations you can test in a single season. Kits with 6–10 varieties let you cover basil (thrips repellent), chives (aphid barrier), and chamomile (ground cover) alongside dill without sourcing seeds separately. A higher packet count also increases the chance of finding at least one variety that thrives in your specific microclimate.
Germination Rate & Testing
Seed quality is measured by germination percentage — industry standard is roughly 75–85% for open-pollinated herbs. Products like Burpee report 35% higher germination than industry benchmarks, reducing the need for oversowing. Lower-quality seeds waste soil space and delay the companion-planting effect, so prioritize brands that disclose germination data or back their seeds with a guarantee.
