1. Choose fertilizer according to the plant's growth stage
Plants use different fertilizers at each growth stage. For example, during the seedling stage, a fertilizer high in nitrogen and low in phosphorus and potassium should be used, while when forcing flowers to bloom, a fertilizer low in nitrogen, high in phosphorus and medium in potassium should be used. For some flower growers, because they have not been growing flowers for long and are not experienced enough, they are not familiar enough with the details of fertilizer use, so it is also advisable to ask experienced growers for advice.
2. Buy fertilizer according to what the plant actually lacks
If a plant lacks certain nutrients, it will show different symptoms, and some people will randomly buy fertilizers and apply them. This often causes fertilizer damage. Fertilizer should be purchased and used according to the actual nutrient deficiencies of the plant.
3. Buy fertilizer according to cost-effectiveness
Some people think that expensive fertilizer is good fertilizer, but this is not the case. At present, a fairly popular way to use fertilizer is 75% controlled-release fertilizer plus 25% water-soluble fertilizer; using them in this ratio is the most economical and effective. In most people's minds, controlled-release fertilizer is expensive and will increase costs, but this is not the case. Water-soluble fertilizer is wasted a lot during use. Controlled-release fertilizer is a coated fertilizer that releases according to the plant's needs, which can reduce fertilizer waste to a minimum and has relatively high use efficiency. In addition, when choosing controlled-release fertilizer, you should also pay attention to some of the explanations provided by suppliers, such as differences in ingredients between different brands. Some brands of fertilizer have patented technologies that can promote the plant's absorption of nutrients, and all this information should serve as a basis for selection.
Because flower growers do not need as much fertilizer as flower producers and farmers, do not be greedy for quantity when buying fertilizer. Once some fertilizers are opened, their chemical ingredients will volatilize if they are not used for a long time. So it is best to buy them when needed and use them immediately after opening.
