Nasturtiums and marigolds can definitely be planted together in your garden for a vibrant, pest-resistant, and mutually beneficial floral display.
Planting nasturtiums and marigolds together is a popular companion planting choice because they complement each other’s growth habits and pest-repelling properties.
In this post, we will dive into why you can plant nasturtiums and marigolds together, how to do it successfully, and the benefits of pairing these two colorful flowers in your garden space.
Let’s get started on exploring this dynamic duo of garden companions.
Why You Can Plant Nasturtiums and Marigolds Together
Nasturtiums and marigolds can be planted together because they thrive well in similar growing conditions and help protect neighboring plants by repelling common pests.
1. Similar Growing Conditions
Both nasturtiums and marigolds prefer full sun and well-draining soil.
They thrive in nutrient-poor soil, which means you don’t have to fuss over specialized fertilization for either plant.
This makes planting nasturtiums and marigolds together an easy, low-maintenance option in most garden beds.
2. Pest-Repellent Properties
One of the key reasons gardeners choose to plant nasturtiums and marigolds together is their natural ability to repel pests.
Marigolds emit a scent that repels aphids, nematodes, and even certain beetles.
Nasturtiums work as a trap crop, attracting aphids away from other plants in your garden.
Together, they form a protective barrier against common pests, reducing the need for chemical pesticides.
3. Complementary Growth Habits
Nasturtiums are trailing or bushy plants that can sprawl across the soil or climb supports, while marigolds are more upright and compact.
This difference in growth habit means they don’t compete aggressively for space.
Planting them together maximizes garden real estate and creates a visually balanced and diverse planting area.
4. Attract Beneficial Insects
Both nasturtiums and marigolds attract beneficial insects like ladybugs, hoverflies, and pollinators such as bees and butterflies.
These beneficial insects help keep harmful pests in check and improve overall garden health by ensuring good pollination.
Planting nasturtiums and marigolds together enhances biodiversity and supports a thriving garden ecosystem.
How to Successfully Plant Nasturtiums and Marigolds Together
If you’re wondering how to plant nasturtiums and marigolds together properly, it’s easier than you might think.
Here are some tips to help you get the best results when combining these two flowers.
1. Choose the Right Location
Pick a sunny spot in your garden that receives at least 6 hours of sunlight daily.
Both nasturtiums and marigolds flourish in sunlight, so make sure their joint planting area isn’t shaded by taller plants or trees.
2. Prepare Well-Draining Soil
While these plants tolerate poor soil, well-draining soil is crucial to avoid root rot.
You can improve drainage by mixing garden soil with sand or organic matter like compost.
This preparation benefits both nasturtiums and marigolds, ensuring healthy root systems.
3. Space Plants Appropriately
Leave enough space between plants to allow airflow and reduce disease risk.
Marigolds should be spaced approximately 8 to 12 inches apart, depending on variety size, while nasturtiums can be spaced about 10 to 12 inches apart for bush varieties.
When planting nasturtiums and marigolds together, alternate them every 10 inches to create a charming and functional patch.
4. Plant Nasturtiums as Ground Cover or Climbers
If using trailing nasturtium varieties, plant them on the edges or at the base of taller plants like marigolds.
Let the nasturtiums trail over garden edges or climb a trellis nearby, adding a cascading effect with their bright flowers and green leaves.
5. Keep Watering Consistent but Moderate
Both nasturtiums and marigolds prefer soil that is moist but not waterlogged.
Water deeply once or twice a week and let the topsoil dry out between watering sessions.
Avoid overwatering marigolds, which can cause fungal diseases, while nasturtiums are fairly drought tolerant once established.
6. Deadhead Regularly
To promote continuous blooming for both nasturtiums and marigolds, deadhead spent flowers regularly.
This keeps the plants focused on producing new blooms rather than seed development.
Ultimately, deadheading will ensure a more vibrant and prolonged flowering season for your garden bed.
Benefits of Planting Nasturtiums and Marigolds Together
Now that you know you can plant nasturtiums and marigolds together, let’s talk about the benefits this combo brings to your garden.
1. Natural Pest Control
Planting nasturtiums and marigolds together is a smart natural pest control strategy.
The scent of marigolds deters many harmful bugs, while nasturtiums serve as an aphid trap, diverting pests away from vegetables and other ornamental plants.
This reduces the need for pesticides that can harm beneficial insects and disrupt your garden’s ecosystem.
2. Continuous Color and Visual Appeal
This pairing fills your space with a radiant mix of orange, yellow, red, and sometimes even cream or peach-colored blooms.
Nasturtiums offer soft, trailing greenery with vibrant flowers, while marigolds deliver bold, upright clusters.
Together, they create stunning seasonal color that enhances garden borders, containers, or raised beds.
3. Supports Pollinators and Beneficial Insects
By providing nectar and pollen, nasturtiums and marigolds attract pollinators to your garden, crucial for fruit, vegetable, and flower production.
Ladybugs and predatory insects are also drawn to these plants, naturally keeping pest populations low.
A thriving community of pollinators and beneficial bugs contributes to a healthy, sustainable garden.
4. Easy to Grow and Maintain
Both plants are beginner-friendly, fast-growing, and forgiving if you miss a watering or two.
Planting nasturtiums and marigolds together means less fussing about soil quality or fertilizer.
You get bright blooms, pest control, and ground coverage with minimal effort — perfect for new gardeners or low-maintenance spaces.
5. Versatility in Garden Design
Whether you’re planting in raised beds, containers, along vegetable rows, or on garden edges, nasturtiums and marigolds fit well.
You can use them as companion plants with veggies or as standalone color beds.
Their versatility lets you experiment with garden layouts to suit your space and style.
