- African Marigolds (Tagetes erecta): These are taller plants that grow up to 3 feet tall. They have large, double flowers in shades of yellow and orange.
- Signet Marigolds (Tagetes tenuifolia): These are smaller plants that grow up to 1 foot tall. They have fine, lacy foliage and small, single flowers in shades of orange and yellow.
Benefits of Planting Marigolds
There are several benefits of planting marigolds in your garden:
- Pest Repellent Properties: Marigolds are known to repel several garden pests, including nematodes, whiteflies, and aphids. This makes them a great companion plant for vegetables and other flowers.
- Aesthetic Appeal: Marigolds have bright, cheerful flowers that bloom from late spring until frost. They can add a splash of color to any garden.
- Ease of Care: Marigolds are relatively easy to care for, making them a great choice for novice gardeners.
How to Plant Marigolds
Choosing a Location
Marigolds prefer a sunny location with well-draining soil. They can tolerate some shade, but they will produce more flowers if they receive at least 6-8 hours of sunlight each day. If your soil is heavy clay or sandy, you can improve its texture and fertility by mixing in some organic matter, such as compost or well-rotted manure.
Preparing the Soil
Marigolds prefer a soil pH between 6.0 and 7.0. You can test your soil pH with a soil test kit available at garden centers. If your soil is too acidic, you can raise its pH by adding lime. If your soil is too alkaline, you can lower its pH by adding sulfur. Marigolds also prefer well-draining soil, so if your soil is heavy clay, you can improve its drainage by mixing in some sand or perlite.
Planting the Seeds or Transplants
You can start marigolds from seeds or transplants. If you are starting from seeds, you can sow them directly in the garden after the last frost date in your area. Plant the seeds 1/4 inch deep and 8-10 inches apart. If you are starting from transplants, plant them 8-10 inches apart. Water the soil thoroughly after planting.
How to Care for Marigolds
Marigolds prefer slightly dry soil, so it’s better to underwater them than to overwater them. Water the plants deeply once a week during dry spells. If the soil is still moist 1 inch below the surface, you don’t need to water.
Marigolds do not need a lot of fertilizer. In fact, too much fertilizer can lead to lush foliage and fewer flowers. If your soil is very poor, you can feed the plants with a balanced, all-purpose fertilizer once a month. Otherwise, it’s not necessary to fertilize marigolds.
Pruning is not necessary for marigolds, but it can help to encourage bushier growth and more flowers. You can pinch off the tips of the stems when the plants are young to encourage branching. You can also remove the spent flowers to encourage more blooms. This is called deadheading.
Pest and Disease Management
Marigolds are relatively pest and disease resistant, but they can occasionally be affected by aphids, whiteflies, and spider mites. You can control these pests by spraying the plants with insecticidal soap or neem oil. Marigolds can also be affected by powdery mildew, a fungal disease that appears as a white powder on the leaves. You can prevent powdery mildew by watering the plants at the base instead of overhead, and by providing good air circulation around the plants. If your plants do get powdery mildew, you can treat them with a fungicide.
Marigolds are a great addition to any garden. With their bright, cheerful flowers and pest repellent properties, they are both beautiful and functional. With a little bit of care, marigolds can thrive in your garden and provide color and beauty all season long.
Frequently Asked Questions
- When to Plant Marigolds: Marigolds can be planted after the last frost date in your area. If you are starting from seeds, you can sow them directly in the garden at that time. If you are starting from transplants, you can plant them at that time.
- How to Deadhead Marigolds: To deadhead marigolds, simply remove the spent flowers by pinching them off with your fingers or cutting them with pruners. This will encourage the plants to produce more flowers.
- How to Overwinter Marigolds: Marigolds are annuals, so they will not survive the winter in most areas. However, you can collect the seeds from the spent flowers and save them for planting next year. Simply remove the seeds from the flowers and let them air dry. Store the seeds in a cool, dry place until you are ready to plant them.
