Can the latest cosmos be planted in saline-alkali soil?

Cosmos is so named because it originated in Mexico and belongs to the Asteraceae family. After being introduced to China, it has always been called cosmos without change. As people gradually came to know this perennial herbaceous plant, especially its impressive ornamental effect, it is very widely used in China. Besides applications in flower fields and gardens, it can even be seen grown in pots in many homes.

From the widespread application of cosmos in China, we can see that this flowering plant has been greatly promoted, and it is now planted all over the country. It is clear that this is not only a highly ornamental flowering green plant, but should also be relatively easy to grow; otherwise, how could it be so widely used?

In fact, whether a plant is suitable for growing in a certain soil requires us not only to be familiar with the plant's growth habits, but also to understand the influence of soil quality on it. Cosmos has the characteristic of tolerating poor soil, but at the same time it also likes a fertile, loose, and well-aerated soil environment. It can be seen that cosmos does not have high requirements for the soil environment, and its adaptability to the soil environment is also relatively strong. Its growth state is mainly affected by temperature; as long as temperature protection can be provided, it can generally maintain good growth. Therefore, even planting cosmos in saline-alkali soil is often possible.

Practice has proven that cosmos does not have very high requirements for pH value, which means that even if it is planted in saline-alkali soil, as long as a suitable temperature environment is provided, it can often still maintain good growth. Moreover, if it is planted as a flower field, as long as the plants can adapt to the current saline-alkali soil environment, they can likewise bloom into a beautiful sea of flowers. Therefore, cosmos can grow normally in saline-alkali soil, and everyone does not need to worry that potted cosmos in their own saline-alkali soil will show poor growth.

However, in order to make the plants grow better, there is generally no need to use overly poor soil for cultivation. Through understanding the growth habits of cosmos, we know that the growth state of cosmos is mainly affected by temperature changes. After all, cosmos is neither heat-tolerant nor cold-tolerant. When the temperature reaches above 35°c, flowering is often affected. Generally, providing the plants with a temperature environment of 15°c-30°c often satisfies the temperature requirements of cosmos very well.
