How should flowers be fertilized for the best results? These taboos should be avoided

Many people grow flowers, and today the editor will share with you

Flowers are better fertilized this way:

(1) Fertilize according to category. Foliage plants should be given more nitrogen fertilizer to make the leaves tender and bright green; flowering and fruiting plants should be given more phosphorus and potassium fertilizer to make the plants bloom early and bear fruit early; bulbous plants should be given more potassium fertilizer to help the bulbs plump up.

(2) Fertilize at the right time. When the leaf color of the flowers becomes lighter and growth slows down, fertilizing 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 dilute fertilizer frequently, to promote rapid and robust growth of the seedlings; after the seedlings are established, the fertilization concentration can be appropriately increased, and phosphorus and potassium fertilizer can be added.

(3) Combine base fertilizer with topdressing. Base fertilizer is mainly organic fertilizer, which supplies nutrients persistently and steadily, 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 fast fertilizer effect, and providing a strong nutrient supply, and is a necessary supplement to base fertilizer.

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

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

(6) Fertilize when the soil is moist. Fertilizing when the soil is dry can easily cause the branches and leaves of the flowers to lose water physiologically and wither, and in severe cases can lead to the death of the plant. On the contrary, fertilizing on rainy days, because the soil water content is high and the ability to absorb and retain fertilizer is poor, makes it easy for the fertilizer to be washed away by rainwater, and it can also cause excessive growth of the plant's branches and leaves.

(7) Cover with an appropriate amount of soil after fertilizing. Many people are used to applying fertilizer in the topsoil layer. This not only easily causes the fertilizer to volatilize and be lost, but also can damage the roots. Especially in hot and dry weather, volatilization is faster and root damage is more serious. Therefore, after fertilizing, an appropriate amount of soil should be covered to prevent nutrient loss and improve fertilizer efficiency.

Taboos of fertilizing flowers:

(1) Fertilizing newly planted plants. Newly planted plants have many root wounds. If stimulated by the outside, the wounds are not easy to heal, which will cause root rot and may even lead to plant death.

(2) Fertilizing sickly and weak plants. Sickly and weak plants have weak growth vigor, poor photosynthesis, slow metabolism, and low ability to absorb fertilizer. If fertilizer is applied casually, it is instead likely to cause fertilizer damage.

(3) Fertilizing during the flowering period. Fertilizing during the flowering period will promote excessive vegetative growth of the plant, easily causing excessive growth and resulting in bud drop and flower drop.

(4) Fertilizing during the dormant period. Flowers stop or slow down growth during the dormant period. If fertilizer is applied, it will break dormancy, prompt the plant to continue growing, and affect flowering the following year.

(5) Fertilizing directly under the root crown. When planting flowers, do not place the plant roots directly on the base fertilizer. Instead, add a layer of soil on top of the fertilizer. Otherwise, it is not only unfavorable for the fertilizer to be fully absorbed and utilized, but also easy to damage the root system. In addition, when topdressing, depending on the plant's growth, apply it in holes at an appropriate distance from the roots to facilitate root absorption.

(6) Applying raw fertilizer. Applying organic fertilizer that has not been fully decomposed to flowers not only easily spreads pests and diseases, but the organic fertilizer will ferment and generate heat during decomposition, damaging the plant roots.

(7) Applying concentrated fertilizer. When fertilizing flowers, the amount of fertilizer must be strictly controlled. Avoid too high a concentration or too large an amount, otherwise it will damage the plant root system and in severe cases cause death. Generally, "apply dilute fertilizer frequently" should be followed.

That is all for sharing the methods of fertilizing flowers and the taboos of fertilizing flowers. I hope this article is helpful to everyone, and I wish everyone good luck.
