About these, do you know? The content about how to plant zinnia seeds and the key points of cultivation techniques for green plants and flowers will be explained in detail by the editor for you next.
Zinnia is a very famous herbaceous flower, which I believe everyone has seen. It can be found in flower seas all over the country. Zinnias can be seen in both the north and south of China, and sometimes even wild varieties can be seen in the wild.
The reason why zinnias are so popular is because of their beautiful flower shapes, wide variety of species, rich colors, and easy maintenance. They can grow into a large area without much care. Most importantly, the cost of propagation is low, so zinnias are often used in the arrangement of many flower seas in China.
Zinnia is also called "hundred-day grass," and its appearance is somewhat similar to that of dahlia. Its flowering period is very long, usually lasting for more than a hundred days. Of course, this does not mean that every zinnia flower can maintain a hundred-year viewing period. Flowers will constantly wither, but new ones will continuously emerge.
Zinnias are often grown as annual plants in many places, which means they are removed after the flowering period and planted again the following year. It is also important to avoid planting the same flower in the same place for consecutive years, as this can easily lead to fungal diseases.
The advantages of zinnias, in addition to their good ornamental value and rich colors, include their strong drought and barren resistance, and their ability to adapt to various environments. They can adapt to warm, cool, and arid conditions.
How to plant zinnia seeds
The disadvantages of zinnias are also quite obvious. Although they love sunlight, they are prone to diseases and pests in excessively hot summer conditions with poor ventilation. Zinnias also have weak cold resistance and can only maintain a good state at temperatures above 15 degrees. A temperature range of 18-30 degrees is best for their growth.
Zinnias come in a wide range of colors, with the most common ones being: orange, yellow, red, pink, purple, white, orange-yellow, and various mixed-color varieties. Most of their petals are single, but some double-petaled varieties have also appeared.
As mentioned above, some zinnia flowers are similar to dahlias. Most zinnia petals are flat, but some are tubular or curly.
Zinnias are suitable for propagation by sowing. Their seeds have a high germination rate and can grow into seedlings by simply sprinkling them on a flat surface, covering them with a thin layer of soil, and watering regularly.
However, it is important to avoid transplanting the seedlings after they have grown. If you want to plant them in pots, use the pots for seedlings directly. If planting in the ground, simply level the soil and sprinkle the seeds on it (cover with soil).
To avoid various diseases and pests in zinnia seedlings after they have grown, it is best to pre-treat the seeds with fungicides and disinfectants before sowing, which can reduce the occurrence of diseases and pests.
The best sowing time for zinnias is from April to June. Sowing in July is already considered late.
