How do flower farmers choose fertilizers?

Planting flowers is inseparable from chemical fertilizers, and all flower growers will encounter the problem of buying chemical fertilizers. Faced with various brands and types of fertilizer products available in the market, how can we choose the most suitable fertilizer for our favorite flowers?

First, choose fertilizer according to the growth stage of plants.

Plants use different fertilizers at different growth stages. For example, fertilizers with high nitrogen, low phosphorus and low potassium should be used at seedling stage, and fertilizers with low nitrogen, high phosphorus and medium potassium should be used at flowering stage. For some flower farmers, it is also appropriate to consult experienced people because they are not experienced enough and are not familiar with the details of fertilizer use.

Second, buy fertilizer according to the actual shortage of plants.

Plants will behave differently if they lack certain nutrients, and some people will buy some fertilizers indiscriminately. It often causes fat damage. The purchase and use of fertilizers should be based on the actual lack of nutrients in plants.

Third, buy fertilizer according to the cost performance.

Some people think that expensive fertilizer is good fertilizer, but it is not. At present, the most popular way to use fertilizer is to add 75% controlled release fertilizer and 25% water-soluble fertilizer, which is the most economical and effective. In the common people's mind, the price of controlled release fertilizer is high, which will increase the cost when used, but it is not. Water-soluble fertilizers will be wasted more in use. Controlled release fertilizer is a kind of coated fertilizer. If it is released according to the needs of plants, the waste of fertilizer can be reduced to a minimum and the efficiency is very high. In addition, when selecting controlled release fertilizers, we should also pay attention to some explanations provided by suppliers, such as the differences in composition between different brands. Some brands of fertilizers have patented technology, which can promote the absorption of nutrients by plants. This information should provide a basis for selection.

Because flower growers don't need as much fertilizer as flower growers and farmers, don't be greedy when buying fertilizer. Once some fertilizers are unpacked, the chemical components in them will evaporate if they are not used for a long time. So it's best to buy as soon as you can, and use it immediately after unpacking.
