Growing Marigolds


Marigolds are easy to grow and can be planted in almost any soil type. They prefer full sun and well-drained soil. When planting, space the seeds or seedlings 6-18 inches apart, depending on the variety. Marigolds can be started indoors 6-8 weeks before the last frost or sown directly into the ground after the danger of frost has passed.

Watering and Fertilizing

Marigolds require regular watering, especially during hot, dry weather. Water the plants deeply once a week, and more often during periods of drought. Overwatering can lead to root rot, so be sure to allow the soil to dry out between waterings. Fertilize the plants with a balanced fertilizer once a month to encourage healthy growth and blooms.

Pest and Disease Control

Marigolds are generally resistant to pests and diseases, but they can still be affected by aphids, spider mites, and whiteflies. To control these pests, spray the plants with a mixture of water and dish soap or use insecticidal soap. Marigolds can also be affected by fungal diseases such as powdery mildew and rust. To prevent these diseases, avoid overhead watering and provide good air circulation around the plants.

If you plant in a shaded area they may be susceptible to mildew.

Overall, growing marigolds is a great way to add color and beauty to your garden. With a little care and attention, these hardy plants will reward you with bright blooms all season long.
