Zinnia Flowers at a Glance
The zinnia is one of the most colorful flowers you can have in the garden. As a matter of fact, zinnias grow quickly and easily everywhere. Zinnias seem to be perfect plants for beginner gardeners because they require minimal care.
In general, there are different kinds of zinnias. The most popular kind is named “Zinnia Elegans.” Most zinnias come from North America, though some are from Central America.
In appearance, zinnia looks like daisies, cosmos, and dahlias thanks to its diverse vibrant colors. Zinnias have long stems that are single and semi-double. The nectar attracts butterflies. Zinnia flowers are represented in a variety of ways with petals arranged in a row, dome, or ball.
Planting Zinnia Seeds
Zinnia is a very resistant plant. Indeed, the flower is available in a wide range of types and colors. Zinnias grow best in moist, fertile, well-drained soil in full sun. In general, plants prefer temperatures of 23 to 29 ° C.
In fact, zinnias prefer long, hot summers, and they don’t like sudden temperature changes and cold weather. The zinnia can’t stand the cold and should be sown under cover if the temperatures are below 18 °.
Sowing is done starting in March under shelter at a temperature of 15 ° Celsius, minimum. Sowing can be done directly in the ground from May. Planting is done starting in May, respecting a space of 20 to 30 cm between each plant.
You can also harvest zinnia seeds from wilted flowers. Then, store them in a moisture-proof envelope, and sow them the following year. Zinnia plants go well with cosmos, carnations, roses, and marigolds.
Useful Tips to Grow and Care for Zinnia Flowers
Most zinnia plants come from the equatorial regions, which is why some varieties are more subject to drought. Regardless of how they can thrive in dry soil conditions, they can produce more flowers if they get enough water. Generally, you can water zinnia flowers two to three times a week, once you notice that the soil is completely dry.
Thus, the zinnia flower requires abundant and regular watering, especially during hot periods. This watering must be carried out directly at the level of the foot of the plant to avoid the risks of disease.
In addition, zinnias are watered on the soil surface, not on their leaves. This keeps the foliage dry and reduces the risk of spreading disease. Most gardeners water their zinnias early in the morning. If watered in the evening, the foliage might remain moist and can be more vulnerable to fungal infections.

Zinnia Flower: Pests and Diseases
More often than not, diseases and infections in zinnia plants happen mainly because of insects. There are two diseases to look for, too, in zinnias, which are powdery mildew and alternaria blotch.

The key to preserve a healthy zinnia is to create an unwelcoming environment for pests. Zinnias should be exposed all times to the sun. Water them regularly but keep the soil well drained to prevent insects from coming.
Remove dead leaves or flowers, too. In addition, weeds must also be removed, which can attract various insects. If all of these steps have been completed and the plants are still suffering, seek advice from a gardening expert.
