Can Marigolds Be Planted With Strawberries in Your Garden?
An In-Depth Guide to Growing Strawberries and Marigolds Together for a Healthier, More Productive Garden
Strawberries are one of the most beloved fruits grown in home gardens—delicious, versatile, and rewarding. If you’re considering planting marigolds alongside your strawberries, you’re on the right track. Marigolds not only add vibrant color to your garden but also offer numerous benefits that can improve the health and yield of your strawberry plants.
In this comprehensive guide, we’ll explore the compatibility of marigolds and strawberries, the benefits of planting them together, how to plant and care for them, and advanced gardening tips to maximize success. Plus, a detailed FAQ section will answer your most pressing questions.
Why Plant Marigolds With Strawberries?
1. Natural Pest Deterrence
Marigolds are famous for their ability to repel many common garden pests that plague strawberries, such as aphids, spider mites, whiteflies, nematodes, and even slugs. They release natural chemical compounds like thiophenes that disrupt the life cycles of these pests.
2. Attraction of Beneficial Insects
Marigold blooms attract pollinators such as bees and butterflies, which are essential for strawberry fruit development. Additionally, marigolds draw predatory insects like ladybugs and lacewings that prey on harmful pests.
3. Soil Health and Nematode Control
Strawberries are vulnerable to root-knot nematodes, which attack roots and reduce plant vigor. Certain marigold varieties, particularly French marigolds (Tagetes patula), produce biofumigant chemicals that suppress nematode populations in the soil.
4. Weed Suppression and Aesthetic Appeal
Marigolds’ dense foliage helps shade the soil, reducing weed growth around strawberries. Their bright flowers add visual appeal, creating an inviting and healthy garden space.
Understanding the Growing Needs of Strawberries and Marigolds
Strawberries
- Light: Full sun (6-8 hours daily)
- Soil: Well-draining, slightly acidic (pH 5.5–6.5), rich in organic matter
- Water: Consistent moisture; avoid waterlogging
- Spacing: 12-18 inches apart depending on variety
- Temperature: Prefer cool to moderate temperatures; mulch helps regulate soil temperature
Marigolds
- Light: Full sun (6-8 hours daily)
- Soil: Adaptable but thrive in well-draining, fertile soil (pH 6.0–7.0)
- Water: Moderate watering; avoid soggy soil
- Spacing: 8-12 inches apart for French marigolds
- Temperature: Warm-weather plants; tolerate heat well
How to Plant Marigolds With Strawberries: Step-by-Step
Step 1: Choose the Right Marigold Variety
French marigolds (Tagetes patula) are the best choice for planting with strawberries due to their strong nematode-suppressing abilities and compact size, which minimizes competition.
Step 2: Prepare the Soil
- Clear the planting area of weeds and debris.
- Test soil pH and amend if needed (add sulfur to lower pH or lime to raise it).
- Incorporate well-rotted compost or organic matter to improve fertility and drainage.
Step 3: Plant Strawberries
- Select healthy, disease-free strawberry plants or runners.
- Plant them 12-18 inches apart in raised beds or well-prepared ground.
- Water immediately after planting.
Step 4: Plant Marigolds
- Space marigolds 8-12 inches apart, interspersed between strawberry plants or along bed edges.
- Marigolds can also be planted in borders around the strawberry patch for maximum pest barrier effect.
Step 5: Mulch and Water
- Apply organic mulch (straw, pine needles) to conserve moisture and keep fruit clean.
- Water plants consistently but avoid waterlogging, especially near strawberry crowns.
Advanced Gardening Tips for Growing Marigolds and Strawberries Together
1. Use Marigolds as a Living Mulch
Plant low-growing marigold varieties around strawberry plants to cover soil, suppress weeds, and maintain moisture without shading strawberries excessively.
2. Rotate Plantings to Manage Nematodes
If nematodes are a concern, rotate your strawberry beds with marigolds grown as a biofumigant cover crop for a season before replanting strawberries.
3. Companion Plant Additional Beneficial Herbs
Add herbs like basil, chives, and garlic near strawberries and marigolds to repel more pests and enhance flavor.
4. Monitor for Diseases and Pests Regularly
Even with marigolds, pests can appear. Check plants weekly and use organic pest control methods as needed to protect fruit quality.
5. Deadhead Marigolds to Extend Blooming
Regularly remove spent marigold flowers to encourage prolonged blooming, ensuring continuous attraction of beneficial insects.
Troubleshooting Common Issues When Growing Strawberries and Marigolds Together
Problem: Poor Strawberry Growth or Yellow Leaves
- Cause: Nutrient deficiency, root rot, or nematodes
- Solution: Test soil, amend with compost, rotate crops, and ensure proper drainage.
Problem: Aphids or Spider Mites on Strawberries
- Cause: Pest infestation despite companion planting
- Solution: Use insecticidal soaps or introduce beneficial insects like ladybugs.
Problem: Marigolds Overcrowding Strawberries
- Cause: Planting marigolds too densely
- Solution: Maintain proper spacing; trim marigolds if necessary to reduce competition for light and nutrients.
Problem: Slugs Damaging Strawberry Fruit
- Cause: Moist conditions and shelter near plants
- Solution: Remove debris, use slug traps, and encourage natural predators like toads.

Comprehensive FAQ: Marigolds and Strawberries Companion Planting
Can marigolds help strawberries grow better?
Yes. Marigolds deter pests, attract pollinators, and improve soil health, all of which support strawberry growth and fruit production.
Which marigold variety is best to plant with strawberries?
French marigolds (Tagetes patula) are most effective for pest control and nematode suppression when planted with strawberries.
How close should I plant marigolds to strawberry plants?
Space marigolds 8-12 inches apart and plant them between or around strawberry plants without overcrowding.
Can I plant marigolds and strawberries in containers together?
Yes, if the container is large enough (at least 12-16 inches deep) with well-draining soil and adequate spacing.
Do marigolds attract beneficial insects to strawberry plants?
Absolutely. Marigolds attract bees, butterflies, ladybugs, and lacewings that pollinate strawberries and control pests.
Will marigolds compete with strawberries for nutrients?
If planted too closely or in poor soil, they might compete. Proper spacing and fertile soil minimize competition.
Are marigolds effective against root-knot nematodes in strawberry beds?
Yes, especially French marigolds, which release biofumigant chemicals that suppress nematode populations.
How often should I water marigolds and strawberries?
Water strawberries consistently to keep soil moist but not waterlogged; marigolds prefer moderate watering with some drying between.
Can marigolds prevent diseases on strawberries?
Marigolds can reduce some soil-borne pathogens by improving soil health but do not replace good cultural practices like crop rotation and sanitation.
When should I plant marigolds with strawberries?
Plant marigolds simultaneously with strawberries or slightly earlier to establish pest protection early in the season.
Can marigolds tolerate the same climate as strawberries?
Yes. Both prefer full sun and moderate climates but can tolerate a range of growing conditions with proper care.
How long do marigolds bloom near strawberries?
With regular deadheading, marigolds can bloom continuously from late spring until the first frost.
Final Thoughts
Planting marigolds with strawberries is a natural, beautiful way to boost your garden’s health and productivity. Marigolds’ pest-repelling properties, their role in attracting pollinators and beneficial insects, and their ability to improve soil conditions make them ideal companions for strawberries.
By choosing the right marigold varieties, maintaining proper spacing, and applying advanced gardening techniques like crop rotation and organic pest management, you can enjoy a lush, thriving strawberry patch full of flavorful fruit and vibrant flowers.
