Detailed Explanation of Scientific Fertilization Methods and Knowledge for Flowers

There are many kinds of flowers and many planting methods. For each different flower, an appropriate fertilization method should be used. Today, the editor will introduce in detail how to fertilize flowers so that they can be more beautiful.

(1) Fertilize at the right time. When flower leaves are found to become lighter in color and growth slows down, fertilization is appropriate. Apply different fertilizers and different amounts according to the different growth stages of the flowers. For example, at the seedling stage, mainly apply nitrogen fertilizer, using thin fertilizer frequently, to promote rapid and robust seedling growth; after the plants are established, the fertilization concentration can be appropriately increased, and phosphorus and potassium fertilizers should be added.

(2) Combine base fertilizer with topdressing. Base fertilizer is mainly organic fertilizer, which provides nutrients for a long time and stably, and can improve soil structure and physical and chemical properties and increase soil fertility. Topdressing is mainly chemical fertilizer, which has the characteristics of containing many nutrients, having a quick fertilizer effect, and providing nutrients strongly, and is a necessary supplement to base fertilizer.

(3) Fertilize by category. Foliage plants should be given more nitrogen fertilizer to make the leaves fresh, tender, and crisp green; flowering and fruiting plants should be given more phosphorus and potassium fertilizers to make the plants bloom earlier and bear fruit earlier; bulbous flowers should be given more potassium fertilizer to help the bulbs become plump.

(4) Apply nitrogen, phosphorus, and potassium fertilizers evenly. For example, favoring nitrogen fertilizer can easily cause excessive growth of branches and leaves, delaying flowering or preventing flowering; favoring phosphorus fertilizer can inhibit the absorption of nitrogen and potassium, causing poor plant growth and easily causing iron and zinc deficiency; favoring potassium fertilizer can inhibit the plant's vegetative growth and cause magnesium deficiency.

(5) Cover with an appropriate amount of soil after fertilizing. Many people are used to applying fertilizer in the surface soil layer. This not only easily causes fertilizer volatilization loss, but also harms the root system. Especially in high-temperature and dry weather, volatilization is faster and root damage is more severe. Therefore, after fertilizing, an appropriate amount of soil should be covered to prevent nutrient loss and improve fertilizer efficiency.

(6) Fertilize when the soil is moist. Fertilizing when the soil is dry can easily cause physiological dehydration of flower branches and leaves, leading to wilting, and in severe cases can cause the plant to die. On the contrary, fertilizing on rainy days, because the soil water content is high and the ability to absorb and retain fertilizer is poor, the fertilizer is easily washed away by rainwater, and it can also cause excessive growth of the plant's branches and leaves.

(7) Apply foliar fertilizer as appropriate. During the period of vigorous plant growth or when trace elements are lacking, spraying foliar fertilizer as appropriate can promptly supplement the insufficient nutrient absorption by the flower roots. However, for foliar topdressing, the concentration must be strictly controlled to avoid leaf damage.

By understanding the fertilizer requirements of flowers, you can target fertilization according to the characteristics of the flowers, so that the flowers grow healthily.
