If you want to try using marigolds for pest control in your garden, here’s what you need to know about how to plant them.

When to Plant Marigolds: You can plant marigolds any time from spring to fall. If you live in an area with a long growing season, you can even sow the seeds indoors in late winter and then transplant the seedlings outside when they are big enough to handle.

How to Plant Marigolds

Marigolds are easy to grow from seed. You can sow the seeds directly into your garden bed or start them off in pots or trays of moist potting mix. If you are sowing the seeds indoors, do so about six weeks before you want to transplant them outside. Sow the seeds thinly so that each one has enough space to grow. Once the seeds have germinated, thin out the seedlings so that only the strongest ones remain. When transplanting seedlings outside, space them 30-45 centimeters (12-18 inches) apart.

The best time to plant marigolds.

To get the most benefits from marigolds in the garden, it’s best to plant them in the spring, after the last frost. You can start them from seed or purchase young plants from a nursery.

How to care for marigolds.


Marigolds are one of the most popular annual flowers grown in gardens. They are easy to grow and care for, bloom over a long period of time, and are available in a wide range of colors. Marigolds can also be used for pest control in the garden.

Here are some tips for growing and caring for marigolds:

  • Choose a sunny location for planting. Marigolds need at least 6 hours of sunlight each day to bloom well.
  • Prepare the planting area by loosening the soil and removing any weeds.
  • Dig a hole that is twice as wide as the root ball of the plant.
  • Mix some compost or organic matter into the soil before replanting.
  • Water plants deeply and regularly, especially during dry periods. Marigolds are drought tolerant but will bloom better with consistent moisture.
  • Deadhead spent flowers to encourage continued blooming.

How to harvest marigolds.

Using marigolds for pest control.

Marigolds secrete a chemical known as pyrethrin, which is toxic to many common garden pests such as aphids, beetles, and worms.

Tips for using marigolds in the garden.


Marigolds are one of the most popular flowers in the world and they have many uses beyond just being ornamental plants. In the garden, they can be used as pest control, as they give off a strong smell that deters insects. They can also be used to companion plant, as they help to improve the health of other plants around them.

When planting marigolds, it is important to space them out properly so that they have room to grow. They should be planted about 18 inches apart in rows that are 24 inches apart. If you are planting them in a pot or container, make sure that it is at least 12 inches deep so that the roots have plenty of room to grow.

Marigolds need full sun in order to bloom properly, so make sure to plant them in an area of your garden that gets at least six hours of direct sunlight each day. They also need well-draining soil so that their roots don’t become waterlogged. If your soil is heavy clay, you may need to amend it with sand or compost before planting.

Once your marigolds are planted, water them deeply and then allow the soil to dry out before watering again. Marigolds are drought tolerant and don’t need a lot of water, so it’s better to err on the side of too little rather than too much. You can fertilize your marigolds once or twice during the growing season with a balanced fertilizer such as 10-10-10.

As your marigolds start to bloom, you can deadhead them regularly to encourage even more blooms. Simply cut off any spent flowers at the stem so that the plant can focus its energy on producing new ones. You can also pinch back the stems of young plants to encourage them to bush out.

At the end of the growing season, you can let your marigolds go to seed and then save the seeds for next year. Or, you can dig up the plants and replant them in another part of your garden. Marigolds are annuals, so they will only last for one growing season before they need to be replaced.
