A Detailed Guide to Flower Seed Storage and Fertilization Methods

Supply the nutrients plants need to the soil. The general principle of fertilizing flowers is to act reasonably in the type and amount of fertilizer, as well as the timing and method of application, according to the biological characteristics of different species and their stages of growth and development. As for base fertilizer, for outdoor flowers it is applied together with soil preparation before planting, and for potted flowers it is applied when potting up; as for top dressing, the principle of applying thin fertilizer frequently is generally adopted. During the seedling stage of flowers, top dressing richer in potassium should be applied; during the growth period, top dressing richer in nitrogen should be applied; during the flowering and fruiting period, top dressing richer in phosphorus should be applied. Top dressing should preferably be applied on sunny days, and it is best when the soil is relatively dry. Whether flowers need fertilizing can be judged by the color of the leaves. Those with dark green, thick and wrinkled leaves are over-fertilized and should stop being fertilized; those with yellowing and thin leaves are deficient in fertilizer and should be supplemented.

How to Apply Top Dressing Through the Roots

Also called "foliar fertilization." A method of fertilizing. A very dilute solution of chemical fertilizer or trace elements is sprayed on the leaves of flowers, so that the fertilizer solution is absorbed and utilized through the leaves. It can supplement the insufficiency of nutrient absorption by the plant roots. Spraying is best done in the early morning, in the evening, or on cloudy days; it is not suitable when the sun is intense or the wind is strong. It is mainly used for flowering shrubs and precious flowers, and is mostly carried out during the peak growth period of flowers or when a certain element is lacking.

What Is the Use of Top Dressing

Fertilizer applied because of nutritional needs during the growth and development period of crops. For flowers, quick-acting fertilizers mainly based on inorganic fertilizers are generally used, so as to supply the growth and development of plants in time. When applying top dressing, the fertilizer must be diluted with water in a certain proportion before watering, so as to prevent direct contamination of the flowers and branches and leaves.
