Today, I'd like to introduce a kind of flower plant that is relatively easy to cultivate. It is Cosmos bipinnatus. It is native to the area around Mexico. In recent years, it can be easily bought in domestic places such as Beijing, Tianjin, Shandong, and Shanxi. It looks petite, and when it blooms, the flowers are abundant, just like young girls dressed in various colored clothes, full of charm.
Cosmos bipinnatus requires relatively abundant sunlight and a good ventilated environment for cultivation. Therefore, it is recommended to cultivate it on the outdoor balcony. If it can only be cultivated indoors, try not to place it in a dark place for a long time, otherwise the leaves are prone to turn yellow due to lack of sunlight. However, in summer, as the sunlight is extremely intense, it is also necessary to shade it at this time, otherwise the overly strong light may damage the leaves of Cosmos bipinnatus and cause them to fall off easily.
Is it suitable to cultivate Cosmos bipinnatus in northern cities? In fact, most of the flowering plants are relatively afraid of cold. So when it is extremely cold in the north, attention should be paid to the indoor temperature. However, there are also advantages to cultivating it in the north. That is, most of the north is in the temperate zone, with a warm and dry climate, and these conditions are still relatively suitable for the growth of Cosmos bipinnatus.
What should be noted when watering it daily? Cosmos bipinnatus naturally likes a humid environment and has a relatively large demand for water. It is necessary to water it regularly. If it is in a dry state for a long time, the leaves will turn yellow. To judge whether it is short of water, you can touch the soil with your hand. When the soil is relatively dry, it is necessary to supplement water in time. However, you can't pour too much water at one time either, because too much water will clog the roots and cause them to rot. Generally speaking, if a large number of leaves turn yellow, it is advisable to consider replanting it, or you can often loosen the soil and place it in a ventilated place to let the water inside evaporate.
For flowering plants, fertilization is very important. Cosmos bipinnatus grows relatively fast, so it requires relatively more nutrients. If the fertilization is insufficient, Cosmos bipinnatus is prone to appear listless in the whole plant. Therefore, it is recommended to apply thin fertilizers frequently when fertilizing. Before using fertilizers, pay attention to the concentration indicated in the fertilization instructions to avoid burning its roots. If the yellowing of leaves has already occurred, it is recommended to use fertilizers that do not need to be diluted. There is no need to worry about the concentration ratio, and they can be sprayed directly. As long as the nutrients are comprehensive, it will gradually regain vitality in about half a month.
