How do I prevent zinnias from getting powdery mildew?

Our Advice:

Powdery mildew is a common fungal disease that can affect zinnias, causing a white or grey powdery coating on the leaves and stems. To prevent powdery mildew in zinnias, it's important to provide good air circulation and avoid overhead watering. Plant zinnias in a sunny location with plenty of space between the plants to allow for good air flow. Water the plants at the base, rather than from above, to keep the leaves as dry as possible. If powdery mildew does occur, it can be treated with a fungicide. Be sure to follow the instructions on the fungicide carefully and apply it as directed. In severe cases, it may be necessary to remove and destroy infected plants to prevent the disease from spreading to healthy plants. Regular monitoring and prompt action can help keep zinnias healthy and free from powdery mildew.

Zinnias are annual flowering plants native to Mexico and Central America. They are popular garden plants due to their vibrant and colourful blooms, ease of cultivation, and long-lasting flowers.

Zinnias: Characteristics

Zinnias come in a variety of sizes and colours, with flowers ranging from small and dainty to large and double. The flowers can be found in shades of red, orange, yellow, pink, white, and even green. Zinnias can grow up to 3 feet tall and 2 feet wide, depending on the cultivar and growing conditions. The leaves of zinnias are lance-shaped and up to 6 inches long.

Zinnias: Cultivation

Zinnias are relatively easy to grow and care for, making them a great choice for beginner gardeners. They prefer full sun and well-draining soil, and can tolerate heat and drought once established. Zinnias can be started from seed or purchased as seedlings, and should be planted after the danger of frost has passed. Deadheading spent blooms can encourage more flowers to grow. Zinnias can also be prone to powdery mildew, so it's important to provide good air circulation and avoid overhead watering.

Zinnias are often used in gardens and landscapes as bedding plants, borders, or as a cut flower for bouquets.

With their wide range of colours and sizes, ease of cultivation, and long-lasting blooms, they are a popular choice for both novice and experienced gardeners.
