When should flowers be fertilized? When is the best time to fertilize the flowers and when should th

Generally, fertilization is applied during the growing season of flowers, and vigorous flowers need more fertilizer. Fertilization should be stopped when the flowers are dormant. When the flower seedlings grow, about 10 days to apply a thin fertilizer water, the best effect of fertilization in the evening, avoid fertilization around noon, high soil temperature is easy to hurt the roots.

Organic fertilizer should be fully decomposed before it can be used. The controlled-release fertilizer developed in recent years is very convenient, and it can gradually release Zhihu's long-term nutrient needs with one use.

Flower fertilization should be done at the right time and in the right amount, while also mastering the season and time. Generally speaking, fertilization is applied during the growing season of flowers, and vigorous flowers need more fertilizer; Vegan fertilizer was applied at the seedling stage, phosphorus fertilizer was mainly applied at the flowering and fruiting stage, nitrogen fertilizer was used for foliage flowers, and fertilization was stopped for flowers in the dormant stage. In addition, it is necessary to grasp the principle of "thin fertilizer and diligent application", that is, "eat less and eat more".

It is best to apply a thin fertilizer water in about 10 days during the growth period of flower seedlings, and the best fertilization effect is in the evening, and fertilizer should not be applied around noon, because the soil temperature is high and the roots are easily injured. Organic fertilizer should be fully decomposed before it can be applied. In recent years, the fertilizer efficiency of controlled-release fertilizer can reach half a year or even longer, and its one-time application rate can be greater than that of water-soluble fertilizer, and the gradual release of nutrients can meet the nutrient needs of flowers for a longer time.

Pay attention to the following points when fertilizing:

1) Fertilization should pay attention to the type of flowers. Different kinds of flowers have different requirements for fertilizer. For example, osmanthus and camellia like pig manure, and avoid human feces and urine; Rhododendron, camellia, gardenia and other southern flowers avoid alkaline fertilizers; Flowers that need to be re-pruned every year need to increase the proportion of phosphorus and potassium fertilizer to facilitate the germination of new branches; Flowers with foliage as the main focus can be more nitrogen fertilizer; Flowers with large flowers (such as chrysanthemums, dahlias, etc.) need to be applied with an appropriate amount of complete fertilizer during the flowering period to make all the flowers open and beautiful; For flowering flowers, fertilizer and water should be properly controlled during the flowering period, and sufficient complete fertilizer should be applied during the fruit-growing period to achieve the expected effect. bulb flowers, apply more potassium fertilizer to facilitate bulb enrichment; Fragrant flowers, enter the flowering period, apply more phosphorus and potassium fertilizers to promote the fragrance of flowers.

2) Pay attention to the season of fertilization. In winter, the temperature is low, the plant grows slowly, and most flowers are in a state of growth stagnation, and generally no fertilizer is applied; Spring and autumn are in the peak period of flower growth, roots, stems, leaves grow, flower buds differentiation, young fruit swelling, all need more fertilizer, should be appropriate more top dressing; In summer, the temperature is high, the water evaporates quickly, and it is the peak period of flower growth, so the concentration of top dressing should be small, and the number of times can be more.

3) The application of organic fertilizer must be fully decomposed, and raw fertilizer cannot be used. In addition, there are many valuable opinions on how to fertilize potted flowers. For example, the data in Jiangsu and other places pointed out that fertilization should look at the growth, set the dosage, and adhere to the "four more, four less, four no", that is:

Apply more yellow thin, more before germination, more before germination, more before pregnancy, and more after flowering; Less application for growth, less application for germination, less application for flowering, and less application in the rainy season; Don't apply for long, don't apply for new planting, don't apply for summer, don't apply for dormancy. At the same time, it is also pointed out that there are three taboos in potted flower fertilization: one taboo thick fertilizer, two taboo hot fertilizer (high soil temperature at noon in summer, fertilization is easy to hurt the roots), three taboos to sit on fertilizer, when planting flowers, apply base fertilizer at the bottom of the pot, do not put the roots directly on the fertilizer, but add a layer of soil to the fertilizer, and then plant the flowers into the pot.

What are the precautions for flower fertilization?

Fertilizers cannot be applied in the same way.

Such as osmanthus and camellia, like pig manure, avoid human urine; Camellias, azaleas, gardenias and other flowers native to the south should avoid alkaline fertilizers; Flowers that need to be pruned every year should increase the proportion of phosphate fertilizer and potassium fertilizer. Flower-based flowers, such as chrysanthemums, dahlias, etc., need to apply an appropriate amount of nutritious fertilizer during the flowering period to make the flowers large and beautiful;

For foliage-based flowers, nitrogen fertilizer should be emphasized.

For flowering flowers, fertilizer and water should be appropriately reduced during the flowering period, and sufficient fertilizer should be applied at the fruit-strengthening stage.

For bulbous flowers, it is advisable to apply more potassium fertilizer to facilitate the enrichment of bulbs; For fragrant flowers, phosphorus fertilizer and potassium fertilizer should be applied during the flowering period to promote the strong fragrance of the flowers.

It is generally suitable between March and October during the growth period of flowers!

<>1. The best time to fertilize flowers is the growth period, generally in spring and autumn, when flowers need more fertilizer, and reasonable fertilizer is conducive to their growth.

2. It is also suitable for fertilization before and after flowering, and it is usually not fertilized when it is in the flowering period. When the plant is in poor growth, in the dormant period, or when it is not or is a newly planted lump, it is generally not fertilized, and in these cases fertilization is easy to inhibit the growth of flowers.

Fertilizing potted flowers generally picks when it grows vigorously, usually, spring and autumn are the growing seasons for flowers, so you may need more nutrients at this time. In summer, the weather is very hot, and it is possible to apply fertilizer appropriately, but the concentration of fertilizer must be low. Fertilizing flowers in summer is best done in the evening, avoiding when the sun is high, as it is easy to burn its roots.

In winter, if the potted plants you are maintaining stop growing, you should stop fertilizing.

When fertilizing flowers, it should be applied in small amounts and many times, avoiding the use of inorganic fertilizers. The fertilizer should not be applied too close to the root system of the plant, and the fertilizer should be fully decomposed before it can be used. In general, do not splash fertilizer on the leaves of flowers when applying fertilizer, as it is likely to burn the leaves.

1. For plants that have just been potted, they generally do not need to be fertilized, and when they have just been repotted, they also need to recover for a period of time before they can be carried out.

2. The amount of fertilizer applied each time must be small, and a small amount of fertilizer should be applied even during the growing period. If too much fertilizer is applied, the root system of the plant cannot absorb it, and the root system of the plant will be burned over time.
