How to fertilize potted flowers? Master these three key points

Potted flowers are generally placed on the balcony, with plenty of sunlight, and watered from time to time, but these two things are completely insufficient. What we pay more attention to is the fertilization step for potted flowers. The following are the three key points for fertilizing potted flowers.

"Timely" means that fertilization must follow the seasons. Generally, spring and summer are the seasons of vigorous flower growth, so fertilizer should be applied, but during high-temperature and scorching weather, fertilization should be stopped or reduced; after the beginning of autumn, flowers grow slowly, so less fertilizer should be applied; in winter, most flowers are in a dormant or semi-dormant state (except those that bloom in winter), so fertilization should be stopped. At the same time, note that once the leaves of the flowers become pale and the plants grow thin and weak, it indicates a lack of fertilizer, and fertilizer should be applied promptly.

"Appropriate amount" means that fertilization must be light and frequent, with the amount determined by the growth condition. "Light" means 7 parts water and 3 parts fertilizer; "frequent" means applying once every 7-10 days; "determining the amount by the growth condition" means "four more, four less, four no, three avoid". "Four more" means apply more when the plant is yellow and thin, apply more before germination, apply more when budding, and apply more after flowering; "four less" means apply less when the plant is plump and strong, apply less when germinating, apply less when flowering, and apply less during the rainy season; "four no" means do not apply when the plant is leggy, do not apply when newly planted, do not apply during the height of summer, and do not apply during the dormant period; "three avoid" means avoid applying concentrated fertilizer, avoid applying hot fertilizer (in summer high temperatures, fertilization easily damages the roots), and avoid applying raw fertilizer. Generally, from the Beginning of Spring to the Beginning of Autumn (do not apply during the dog days), apply dilute fertilizer water once every 7-10 days; after the Beginning of Autumn, apply once every 15-20 days.

"Appropriate" means that when growing flowers, fertilization must absolutely not be excessive. If too much or too concentrated fertilizer is applied, it will cause the roots of the flowers to lose water, leading to the leaves gradually scorching yellow, the new buds slowly drying up, and eventually death. At the seedling stage, in order to promote the growth of young seedlings, more nitrogen fertilizer can be applied; at the budding stage, in order to promote bright flowers and large fruit, more phosphorus fertilizer should be applied. Before fertilizing, loosen the soil to help the fertilizer water seep down. The best time to fertilize is in the evening, especially in summer, when the temperature at noon is relatively high and fertilization easily damages the roots. After fertilizing in the evening of that day, water in the early morning of the next day (commonly known as "returning water") to dilute the fertilizer liquid so that the plant can absorb it easily and avoid fertilizer damage.

It is necessary to correctly master these three key points of fertilizing potted flowers, so as to fertilize potted flowers reasonably. This is a key step. If fertilization is just right, it will be of great benefit to the growth of the flowers, such as lush branches and leaves, bright and colorful appearance, and so on.
