Fertilizer provides nutrients for the growth of flowers and is the basis for ensuring the health of flowers. The purpose of fertilization is to supplement the deficiency or imbalance of nutrients in the soil and meet the demand of flowers for nutrients. Reasonable fertilization and adequate nutrition will make flowers thrive and flourish. On the contrary, unreasonable fertilization can not only promote the growth of plants, but also lead to the white growth of flowers, which may lead to the death of flowers in severe cases. So how can we achieve reasonable fertilization?

First, timely and appropriate fertilization.

Timely means fertilizing at the right time. Such as flowers before flowering and fruiting, when growth is stagnant, and when buds are rarely pregnant. Fertilization can help flowers grow rapidly in this period and achieve the effect we need. Appropriate amount refers to the flexible control of fertilization according to the actual situation such as time, weather, flower size and so on. The amount of flower fertilization can follow the principle of "four more, four less and four noes".

Second, because of "planting" and fertilization.

"Species" refers to different kinds of flowers. We need to fertilize flowers according to different varieties and different growth periods. Different varieties of flowers have different requirements for nutrients. For example, gardenia, camellia, azalea and other flowers that like acidic soil should use acidic or physiologically acidic fertilizers such as ammonium sulfate, potassium nitrate and calcium superphosphate when fertilizing: the same flower will need different nutrients at different growth stages. For example, more phosphorus and potassium fertilizers should be applied after pruning to facilitate the germination of new branches and leaves. Bloom needs complete fertilizer when viewing flowers, which is conducive to the gorgeous flowers; The amount of phosphorus and nitrogen fertilizer should be increased in bud stage, but water and fertilizer should be controlled in flowering stage and complete fertilizer should be supplemented in strong fruit stage.

Third, rational fertilization.

When fertilizing, we should also pay attention to the methods and choose the appropriate methods to fertilize the flowers. Fertilization methods include applying base fertilizer and topdressing. When planting flowers, base fertilizer is to mix fertilizer and soil in a certain proportion and pad it at the bottom or around the basin. Topdressing is to supplement nutrition for flowers during their growth period. There are many ways of topdressing, including spraying, acupoint application, liquid application, smear application and so on. When the flowers are just planted or in the seedling stage, the roots of the flowers are underdeveloped or there are few leaves, and the photosynthesis is weak, so we can choose to spray them. But pay attention to the timing of spraying, and the temperature 18 to 25 degrees is suitable for this method. We generally choose to spread granular compound fertilizer, that is, spread the fertilizer evenly on the basin soil and let it slowly melt into the soil. For rotten farmyard manure, we generally choose acupoint application to cover up the smell of farmyard manure.

Through our introduction, I believe everyone has a deeper understanding of how to grow flowers reasonably and how to grow flowers all year round.
