Can You Plant Dill and Basil Together? Expert Guide

By James Wilson · January 24, 2026

Yes, you can plant dill and basil together—they share similar growing conditions and can thrive in the same garden bed or container with proper spacing and care. However, monitor for competition and pest attraction.

Why Dill and Basil Make Good Garden Companions

Planting dill and basil together is not only possible but often beneficial when managed correctly. Both are popular culinary herbs that prefer warm, sunny environments and well-drained soil. Their compatibility stems from overlapping climate and soil needs, making them ideal candidates for co-planting in herb gardens or containers.

Shared Growing Requirements

Sunlight: Both require 6–8 hours of full sun daily.
Soil pH: Prefer slightly acidic to neutral soil (6.0–7.0).
Watering: Need consistent moisture without waterlogging.
Temperature: Thrive in warm climates (70–85°F / 21–29°C).

Potential Challenges When Growing Dill and Basil Together

Despite their compatibility, several factors could hinder successful co-cultivation.

Competition for Resources

Dill grows tall (up to 4 feet) and may shade shorter basil plants, reducing photosynthesis and stunting growth. Additionally, both have moderate to high nutrient demands, increasing root competition if planted too closely.

Attracting Similar Pests

Dill attracts aphids, spider mites, and tomato hornworms.
Basil is vulnerable to slugs, thrips, and downy mildew.
Proximity may increase pest pressure or disease spread.

Self-Seeding and Invasiveness

Dill readily self-seeds and can become invasive in some gardens, potentially overcrowding basil unless monitored or deadheaded.

Factor	Dill	Basil	Compatibility Rating
Optimal Temperature (°F)	65–75	70–85	High
Sun Exposure	Full sun (6–8 hrs)	Full sun (6–8 hrs)	High
Soil pH Preference	6.0–7.0	6.0–7.0	High
Water Needs	Moderate, even moisture	High, consistent watering	Medium
Mature Height	3–4 ft	1–2 ft	Medium
Pest Attraction	Aphids, spider mites	Thrips, slugs	Medium-Low

The table shows strong alignment in temperature, sunlight, and soil pH preferences between dill and basil, supporting their co-planting potential. However, differences in mature height and watering frequency suggest careful spacing and microclimate management are needed. Pest overlap is moderate, so integrated pest monitoring improves success.

Best Practices for Planting Dill and Basil Together

Spacing and Layout

Space plants at least 12–18 inches apart. Position basil on the south or east side of dill to prevent shading. Use containers if space is limited to better control growth.

Soil and Fertilization

Use rich, loamy, well-draining soil.
Incorporate compost before planting.
Fertilize lightly every 4–6 weeks with balanced organic fertilizer.

Pruning and Maintenance

Regularly pinch back both herbs to encourage bushiness and delay flowering. Remove dill flowers if self-seeding is a concern. Harvest leaves from the top down to promote airflow and reduce disease risk.

Frequently Asked Questions About Planting Dill and Basil Together

Can dill and basil grow in the same container?

Yes, but use a large pot (at least 12 inches deep and wide) with drainage holes. Ensure both plants receive equal light by rotating the container and prune regularly to manage size differences.

Does dill affect the flavor of nearby basil?

No scientific evidence suggests dill alters basil’s flavor through proximity. However, cross-contamination during harvest or drying should be avoided to preserve distinct taste profiles.

Will dill attract pests that harm basil?

Dill attracts beneficial insects like ladybugs and lacewings, which can help control pests on basil. However, it also draws aphids and spider mites, so monitor both plants closely and treat infestations early.

How often should I water dill and basil when grown together?

Water when the top inch of soil feels dry—typically 1–2 times per week depending on climate. Basil usually needs more frequent watering than dill, especially in hot weather.

What herbs should not be planted with dill or basil?

Avoid planting dill near carrots (attracts carrot rust flies) or cilantro (different moisture needs). Keep basil away from rue and sage, which inhibit its growth. Rosemary prefers drier soil and isn’t ideal with either.
