The Long Answer

Yes! Peppers and Marigolds make great garden companions. There are a few things to consider when planting the two together, and your strategy may differ depending on how your garden is setup, and what types of peppers you plan to grow.

About Peppers

Peppers prefer to grow in a warm place with as much sunlight as possible.

Peppers are full sun, heat-loving vegetables that are a staple to most home gardeners. They are planted in mid to late spring and can produce bounties of peppers if given the right conditions.

Peppers are fairly easy-going plants. They are prone to a few insects such as potato beetles, worms, and root nematodes. Marigolds can help in deterring some of these pests and help protect your pepper plants from damage.

Bell peppers are one of the most popular garden grown vegetables, and certain varieties can have a smaller footprint, making them a great choice for vegetable gardeners.

About Marigolds

Marigolds are magnificent annuals that can repel pests and attract beneficial insects and pollinators.

Marigolds are flowering annuals that do best in warm climates. They have fine, dark-green leaves, and display blooms in warmer shade (reds, yellows, oranges). There are two types of marigolds: African and French. African marigolds tend to be taller than French marigolds.

Marigolds contain chemical compounds in their leaves and root systems that are known to deter harmful insects and other garden pests.

They can keep away bugs such as potato beetles, root-knot nematodes, and cabbage worms. They can also attract beneficial insects such as hoverflies, butterflies, and ladybugs.

Benefits of Marigolds in the Garden:

  • Add biodiversity to your garden and backyard areas.
  • Attract butterflies and other pollinators to the surrounding areas.
  • Deter harmful insects and other pesky critters.
  • Low maintenance to grow and provide pop of color all summer long.

Growth Requirements

Both of these plants are fairly low maintenance once established. Picking a good location, soil, and climate are just a few things to consider when considering planting these two together.

Both plants require at least 6-8 hours of sunlight per day.

Both of these plants need full sun to grow best. This means they should be in an area that receives 6-8 hours of direct sunlight daily.


Yellow flowers grow in the garden
Both plants prefer to grow in warm climates.

Both plants are true annuals, meaning they will only live for one season, and then die off before winter sets in. They grow best in warm climates and are very tender to cool temperatures that dip below 45 degrees Fahrenheit.

When planting peppers, keep in mind that they need enough space to grow.

When choosing a location for both plants, it is important to consider space and sunlight. Some pepper varieties grow large and tall, while some stay compact or can even be planted in containers. Keep in mind the mature size of your pepper plants when choosing a location.

Both of these plants grow best in full sun. Plant marigolds in a location that won’t get shaded out by the pepper plant or other crops.

Container vs. Garden

When it comes to planting them together, most gardeners are either planting them together in raised beds, in the ground, or in containers. There’s a slightly different approach depending on how you plan to grow them together.


Wooden boxes of plants
If you want to plant them together in a container, plant them separately.

There are certain varieties of peppers that maintain a small, compact growing habit making them perfect for patio pots or containers. If you are planting your pepper plants in containers or pots, but still want to plant marigolds nearby, plant the two in separate containers.

Although marigolds and patio pepper varieties have a smaller growth footprint, using two separate containers will ensure both root systems have enough room. Place the containers close together so that the peppers will still benefit from your marigolds.

Garden/Raised Bed

You can also plant the pepper in a raised bed, giving it plenty of sunlight and room to grow.

Planting in the garden or a raised bed is a relatively simple process. Take note of which parts of your garden receive the most sunlight throughout the day. You’ll want to plant your peppers and marigolds in that location. Take into account both of the plants’ mature size when picking the right location to ensure they both have enough room to grow.

Plant marigolds 10 inches apart from other crops to give them enough room to grow and good airflow.

Marigolds should be planted at least ten inches away from your other crops or plants. This will ensure they have enough room to grow to mature size, and still allow good air flow to the plants leaves.

Pepper plants at mature size can range anywhere from 2 feet to 5 feet tall depending on the variety. Most grow to about 2 feet in diameter. Keep this in mind when spacing out your pepper plants. You want to give the plants enough room to reach mature size comfortably but allow room for the plant to breathe and make harvesting accessible.

When planting marigolds and peppers together allow each plant to have its required space, and some. You want to make sure they don’t grow too close together as this can crowd the leaves, hindering air flow and sunlight.

Seeds vs. Transplants

Marigold seeds and transplants are easily accessible at nurseries or local garden centers. Pepper seeds are usually sold at these places as well, but you will see more varieties readily available as transplants.

Pepper seeds germinate within 10-14 days.

Starting pepper plants from seed can be a cost effective way to start your own pepper plants in early spring. Seeds can also be direct sown into your garden if you live in a warmer climate that has a long growing season.

Seeds should be kept warm and moist until germination (usually 10-14 days). Germination time can fluctuate depending on temperatures and environmental factors.


Flower transplants going in garden
Before transplanting marigolds into the garden, make sure that the danger of frost has passed.

When transplanting, make sure the danger of frost has passed in your area. Pepper and marigold plants are very sensitive to cold temperatures and this could severely damage your plants. Water frequently after transplanting to help the root systems get well established.


Farmer putting plants in soil
Before planting peppers, make sure to add compost or mulch to the soil.

Pepper plants do best in well-draining, fertile soil. They do not like to stay wet for too long, so soils that contain clay can negatively affect their growth.

Before planting peppers in a garden bed amend with a compost or peat-based mulch to aerate and freshen the soil. Marigolds are not too picky when it comes to soil, if your soil is well-draining they will be perfectly content.


Farmer holding fertilisers for peppers
Pepper prefers all-purpose fertilizer.

Pepper plants will benefit from frequent fertilization once planted in your garden or container. An all purpose fertilizer or vegetable specific blend will work great. Marigolds do not require fertilization throughout the season, but you might see more blooms if fertilized.


Watering garden flowers and vegetables
Since both plants do not like to stay in moist soil for long periods of time, make sure the soil dries out between waterings.

Watering consistently and frequently right after you plant is crucial to help the root systems adapt and get well established. Throughout the growing season, water your peppers and marigolds regularly. Both of these plants both dislike staying consistently moist for too long. It is important to let the soil dry out in between waterings.

Marigolds benefit from pruning dead flowers to encourage new growth.

Once established, pepper plants will not require any maintenance past irrigation and fertilizing. Marigolds are low maintenance as well. While deadheading marigolds is not required in order to keep happy and healthy plants, they will benefit from frequent deadheading. This will also help encourage new flowers once the old ones begin to fade and dry out.

Final Thoughts

Marigolds and peppers make great companion plants for many reasons. Marigolds add many benefits to your garden and can directly benefit your pepper plants when planted close by. So, just to recap the benefits of marigolds as companions to garden grown peppers:

Marigolds can…
  • Attract butterflies and other pollinating insects.
  • Deter harmful insects and root pests.
  • Deer and rabbit resistant.
  • Add biodiversity, reduce weeds, save space.

Now that you know that there’s some great benefits to planting these two plants together in the same area, it’s time to get planting!
