How to tell what fertilizer to apply to your flowers

Fertilization is indispensable for the growth of flower pots, and the nutrients in the soil are difficult to meet the nutrients required for plant growth, so how to judge what fertilizer the plant is missing?

The plant lacks calcium.

Symptom. When the plant lacks calcium, the edge of the leaf will be yellow, wilted, and hooked, the root system will not grow well, the root tip will be brown, and the root will be rotten and cracked, or even on the verge of death.

Resolution. Calcium fertilizer (e.g. lime) can be applied to the potting soil to improve plant growth.

The plant lacks iron.

Symptom. When the plant lacks iron, the old leaves are still green, but the new leaves turn yellow, and the veins do not turn yellow. Later, the leaves turn yellowish-white, and the veins gradually turn yellow. When the iron deficiency of the plant is severe, the leaves will appear small spots, and the leaves will dry up or even die.

Resolution. Apply fertilizer containing ferrous sulphate to plant roots or spray onto plant leaves with foliar fertilizer containing iron.

The plant lacks manganese.

Symptom. When the plant is deficient in manganese, there are yellow-brown or reddish-brown spots on the tips of the flower leaves, and the leaves are grayish-white, and the small spots at the tips gradually expand until the leaves wilt.

Resolution. Apply manganese-containing fertilizers to plants in a timely manner.

Plants lack phosphorus.

Symptom. When the plant is deficient in phosphorus, the growth is slow, the flowering period is delayed, the leaf color turns dull dark green, the plant loses its luster, small purple or red spots appear, and in severe cases, the leaves die.

Resolution. Apply phosphorus fertilizer to the plants.

The plant lacks potassium.

Symptom. Brown spots appear on the flower leaves, and the old leaves are irregularly wrinkled and bent, and the edges are scorched.

Resolution. Supplement the plants with potassium-containing fertilizer.

Magnesium is lacking in the plant.

Symptom. The plant slowly turns yellow starting from the lower half of the leaf and then the whole plant turns yellow, and the veins are still green. If not remedied in time, the leaves will turn brown and die.

Resolution. Apply magnesium-containing fertilizer to the plants.

The plant lacks sulfur.

Symptom. Starting from the vein part of the leaf to turn yellow, the leaf will slowly develop red spots, and eventually cause the entire plant to die.

Resolution. Apply sulfur-containing fertilizer to the plants.

The plant is deficient in boron.

Symptom. The top of the flower stops growing, the new leaves are deformed and shriveled, the leaf veins are yellow, the growth rate of the plant is slowed down, and the plant no longer flowers and bears fruit when there is severe boron deficiency.

Resolution. Apply boron-containing fertilizer to the plants.

Raising flowers, skillfully "choosing fertilizer", what flowers apply what fertilizer, skillfully distinguishing!

Under the premise of meeting the demand for nitrogen fertilizer, the proportion of phosphorus and potassium fertilizer should be paid attention to. Foliage flowers were supplemented with potassium fertilizer on the basis of nitrogen fertilizer. Ornamental flowers are mainly cultivated with nitrogen fertilizer, with phosphorus and potassium fertilizer, trace elements and rare earth fertilizer.

Perennial flowers need a lot of nitrogen fertilizer in the rapid growth stage of seedlings, and attention should be paid to supplementing phosphorus and potassium fertilizers. Generally speaking, nitrogen fertilizer is applied during the growth period of flowers, and no fertilization is required during flowering, phosphorus and potassium fertilizer should be applied before flowering, and top dressing should be applied after flowering.

Taking azaleas as an example, when azaleas are cultivated as pots, the bottom should be applied before planting, and phosphorus and potassium fertilizers should be applied before flowering to promote the formation and flowering of flower buds; After the rhododendron flowering, nitrogen fertilizer-based fertilizer should be applied to promote the growth of branches and leaves, and new branches and leaves should be applied with phosphorus fertilizer and nitrogen and potassium fertilizer combined with nitrogen and potassium fertilizer after lignification. Rhododendron does not need to be fertilized during the dormant period in winter, and the application of phosphate-based fertilizer before flowering can make the flowers of the plant large and colorful.

In spring and autumn, basal fertilizer can be applied, and phosphate fertilizer can be applied appropriately; Nitrogen fertilizer is applied to flowers when they sprout and remove leaves in spring, which can ensure the nutrition of the plant and make it grow vigorously; After entering the summer, many woody flower buds begin to differentiate, at this time, it is necessary to ensure the best phosphorus and potassium fertilizer and control the amount of phosphate fertilizer.

Nitrogen, phosphorus, and potassium fertilizers are a large number of elements, which are generally sufficient in the soil, and flowers are mainly supplemented with micro-fertilizers, that is, foliar fertilizers. It has the characteristics of quick effect....

The scale fertilizer for viewing flowers and fruits is the main fertilizer, and the nitrogen fertilizer for viewing leaves is the main fertilizer.

The potting fertilizers we commonly use in daily life are generally divided into chemical fertilizers and organic fertilizers.

Chemical fertilizer is also known as mineral fertilizer, fertilizer is simple, fertilizer effect is fast, easy to use, but the fertilizer is violent and not lasting, when the humus contained in the potting soil is less, the long-term use of chemical fertilizer alone is easy to make the soil compacted and cause the lack of certain nutrients.

Therefore, when using chemical fertilizers, if the potted soil is more reasonable, the plant is generally not prone to trace element deficiency, but if the soil is relatively simple, it is easy to cause the potted plant to lack trace elements.

Organic fertilizerOrganic fertilizer, also known as complete fertilizer, has a soft fertilizer effect, long validity period, contains a variety of trace elements necessary for plant growth and development and a large amount of organic matter, and the humus in organic matter can constitute a good potted soil structure, enhance the fertilizer retention, water retention and permeability of the soil.

And that's not all. Organic fertilizers also contain a lot of nitrogen, phosphorus, and potassium.

What are nitrogen, phosphorus, and potassium?

Nitrogen, phosphorus, and potassium are the three major elements needed for plant growth.

Indispensable. All plants need nitrogen, and for flower plants, its main role is to promote flower growth, leaf growth, and leaf greening.

If your plant is nitrogen deficient, it will look smaller, and then it will not grow for a long time or slowly, and the leaves will be yellowish-green, and it will not bloom.

Like nitrogen, phosphorus is also needed by all plants, it can not only promote plant germination and differentiation, but the most important function is actually to promote plant rooting.

If your plant is deficient in phosphorus, it will grow slowly, the leaves will be smaller, the flowers will be fewer, the branches will be reduced, and the old leaves will turn yellow first and then purple.

For plants, potassium's main role is to promote the strength of plant stems, improve the plant's ability to resist cold and drought, and in addition to promoting the development of roots.

If your plant is deficient in potassium, then its stems will be smaller, the edges of the old leaves will be spotted, and the tips of its leaves will turn yellow and slowly die.

The organic fertilizer is rich in nitrogen, phosphorus, potassium and trace elements, which can provide long-term nutrients for the growth of plants, and can effectively prevent the emergence of nutrient deficiency in potted plants.

Therefore compared to fertilizers.

The nutrient composition of organic fertilizer is relatively comprehensive.

It is an ideal nutrition for potted flowers**.

There are specially formulated special flower fertilizers on the market, which can ensure that the nutritional elements of leaves, flowers and fruits are sufficient, and it is the best choice for beginners.

Long-acting controlled-release fertilizers.

Fertilizer for trees and shrubs with an effective effect of 6 months under 21 environmental conditions. Urea nitrogen 18%, containing trace elements. Trace element fertilizer, fertilizer effect of 12 months, containing iron, sulfur, calcium, magnesium, manganese, zinc, etc., suitable for most flower farming.

Fertilization of high iron surface.

It is specially used for foliar spraying of plants that originate from the south and have a high demand for iron, with a fertilizer effect of up to 4 months, and contains trace elements such as urea nitrogen, ammonium nitrogen, iron, and calcium. Special fertilizer for evergreen plants, fertilizer effect up to 4 months, containing urea nitrogen, ammonium nitrogen, calcium, magnesium, manganese, iron.

Palm Springs Fertilizer.

The fertilizer efficiency is up to 4 months, and the proportion of nitrogen, phosphorus and potassium content is 3 1 3, which is suitable for the nutritional needs of palm plants, and contains calcium, magnesium, manganese, iron and other medium and trace elements.

Special fertilizer for pine and spruce.

The fertilizer effect is up to 9 months, containing nitrate nitrogen, urea nitrogen, ammonium nitrogen and trace elements. Special fertilizer for woody plants, fertilizer effect up to 14 months, containing nitrate nitrogen, ammonium nitrogen, no trace elements.

How to choose fertilizer for raising flowers? Commonly used flower hypertrophy is recommended, and novices can easily master it!

Choose my rice field, and the fertilizer water will not flow into the outsider's field.

In the plant germination and growth stage, we should apply nitrogen fertilizer to the plant, mainly fertilizer with no missing other elements, to promote the vigorous growth of the plant; When the plant flowering, the fertilizer based on phosphorus fertilizer promotes the differentiation of plant flower buds, which is conducive to the plant to give birth to more flower buds, generally the flowering plants we raise at home, such as those that only bloom once a year, we can choose fertilizers with high phosphorus content before it blooms, such as potassium dihydrogen phosphate, so that after it is used, it can promote its rapid differentiation of flower buds.

It is not advisable to use chemical fertilizers for raising flowers at home. The main fertilizers such as nitrogen, phosphorus, and potassium needed to grow flowers can be collected in daily life. For example:

Moldy inedible waste peanuts, beans, melon seeds and miscellaneous grains are nitrogen-containing fertilizers, and the 16 elements required for the growth of flowers are: carbon, hydrogen, oxygen, nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, iron, manganese, copper, zinc, boron, aluminum, chlorine. Flowers generally have a large demand for the first 9 elements, we choose fertilizers with high nitrogen content, and other elements are not missing, so that the nitrogen content is high, it will quickly grow branches and leaves, and the root system can also grow because there is no lack of other elements.

The principle to be followed is to apply thin fertilizer frequently, adjust the frequency of use according to the needs of plant growth, and give fertilizer every time you water, if it is a flowering plant, the ratio of nitrogen, phosphorus and potassium must be slightly higher, and the frequency of use can be larger. During the growth of flowers, due to the limited potting soil, the basal fertilizer loses its strength after a long time and can no longer provide sufficient nutrients for the plants. At this time, it is necessary to selectively supplement various fertilizers according to the needs of flowers during different growth periods.

Exposed plants can choose to fertilize on rainy days, put a few grains of nitrogen, phosphorus and potassium compound fertilizer in the pot, and plant the plants in the ground, just sprinkle the compound fertilizer directly in the ground. Fertilization depends on the growth and the dosage is determined. Adhere to the principle of "four more, four less, and four no", that is, apply more yellow and thin, more before germination, more before germination, more after flowering; Less application for growth, less application for germination, less application for flowering, and less application in the rainy season.

The choice of fertilizer for raising flowers should be based on different periods. When planting flowers, add farm fertilizers to the soil, such as poultry and livestock manure, or buy special flower fertilizers directly from the Internet to provide nutrients for flowers and trees slowly and continuously. When the flowers and trees enter the growth period and are ready to bloom, they need to add fertilizer and apply some special compound fertilizer to the plants to help the plants thrive.

Raise flower plants to fertilize according to its growing season, can not be fertilized indiscriminately, the temperature is too high in summer according to the plant growth requirements less fertilizer or no fertilizer, most of the plants in winter stop growing when the temperature is too low to suspend fertilizer.

Flower fertilization is very particular. You can't water and fertilize the flowers uncontrollably, otherwise it is easy to raise the flowers to death. Fertilizer can choose to have well-rotted organic fertilizer, such as chicken manure and sheep manure. If you apply fertilizer, you can use a small amount of fertilizer many times, and don't put too much fertilizer at once.

It is necessary to use the fertilizer that was bought. You can ferment your own fertilizer, such as bean cake. Bean cake is a good nitrogen fertilizer, which can promote the growth of plant roots, green leaves, and thick branches.

When changing pots, you can add a small amount of fermented cow dung and sheep manure to the bottom of the pot. Fermented cow and sheep manure is a good fertilizer. It is not easy to burn flowers, and can supply nutrients to the potting soil for a long time to avoid the hardening of the potting soil.

Fertilization should be applied with organic fertilizer, and fully decomposed organic fertilizer should be selected. And a small amount many times, you can't apply too much fertilizer at a time, and it will burn the roots. It is necessary to pay attention to the application of basal fertilizer. Use chicken manure, sheep manure, rotted soybean meal, etc. to make liquid fertilizer.

Generally, raising flowers to fertilize plants is divided into three segments, the first is the growth of flowering fertilizer, which is to ensure the growth needs of plants in the process of plant growth, and there is the top dressing after flowering, due to the excessive consumption of nutrients in flowering, top dressing, the third is overwintering fertilizer, the application of phosphorus and potassium fertilizers in winter is conducive to improving plant cold resistance, and can be conducive to the growth of flowers in the spring of the next year.
