How should osmanthus be fertilized reasonably? What fertilizer to apply to potted osmanthus?

It is recommended not to use rice washing water and tea water for a long time, first of all, it can not play a role in fertilizer for osmanthus water, and long-term use will also alkalize the soil. Osmanthus does not have high requirements for soil and moisture. The soil should not be too wet, especially if it is waterlogged.

In the event of waterlogging, the root system will rot and the leaves will fall off, resulting in the death of the whole plant. Osmanthus flowering requires a period of fog and humidity conditions with clear days and cool nights and moist rain and dew.

Reasonable fertilization can make osmanthus grow luxuriantly and bloom well, and will not produce scorched shoots and unable to bloom.

Osmanthus is fertilized 2 times a year. Apply basal fertilizer in winter, and apply enough from ll-December to promote the flourishing of branches and leaves and the differentiation of flower buds in the coming year; Summer topdressing, which is carried out in July to promote the flourishing of autumn flowers. Flower sulfur, osmanthus should pay attention to irrigation; But when flowering, you should control the watering, otherwise it is easy to fall flowers.

When using fertilizers, organic fertilizers, such as compost manure, must be used only after they have been fully decomposed and fermented (the sign is that the fertilizer juice is blackened). The use of chemical fertilizers should clarify the composition and content of fertilizers, and use them reasonably according to the different growth and development stages of osmanthus flowers. The safe concentration of urea is 0 5-1 0 and the safe concentration of superphosphate is 2.

1. Rice washing water is very good, but the method should be right:

Find a large plastic bucket with a lid. Pour in the daily rice washing water and cover tightly. It's better to put some orange peel and rotten oranges in it.

After three months, it is basically decomposed into a natural acidic fertilizer, and you can water the osmanthus. Water about half a month, mix with half of the water. The rice washing water can be added as soon as it is used up and recycled.

2. Osmanthus is a typical acid-loving plant, and the tea water contains alkali and cannot be used.

3. In fact, osmanthus likes livestock manure the most, as the saying goes, "pig manure osmanthus is fragrant". However, it is not suitable to grow at home. The above-mentioned rice washing water is the best choice for household use. Remember to cover tightly or there will be no smell.

To fertilize osmanthus, it is necessary to apply thin fertilizer frequently or from light to thick, and to achieve reasonable fertilization according to seasonal and temperature changes. When the growth of plant shoots is slow, apply more delayed fertilizer, because delayed fertilizer can slowly supply various nutrients to the growth needs of osmanthus; In the vigorous growth period of the plant, it is necessary to apply more fast-acting fertilizer, because after the application of fast-acting fertilizer, it can be effective immediately, but the concentration should be mastered when applied, and raw fertilizer should not be used, so as not to cause fertilizer damage. Osmanthus is cultivated in pots or in the open field, generally after the spring shoots germinate, it will enter the vigorous growth period, also called the vegetative growth period, this period, mainly ornamental leaves.

Therefore, nitrogen and potassium fertilizers should be applied as the main fertilizers, supplemented by other fertilizers, fertilized once a month for open field cultivation and twice a month for pot cultivation.

Potted osmanthus fertilization points in four seasons.

First, the key points of fertilization in spring.

What fertilizer is good for potted osmanthus, spring belongs to the growth period of osmanthus, the growth of plants during this time needs a lot of nutrients, and the fertilization in spring should be based on nitrogen fertilizer, nitrogen fertilizer is the key to promote plant growth. It is recommended to apply liquid fertilizer with nitrogen content every half a month during this period.

Second, the key points of summer fertilization.

Fertilization in summer is divided into two phases, and in early summer, it is also necessary to ensure that the plants have sufficient nutrients, and during this time, thin liquid fertilizer is applied once every 20 days. In the middle of summer, the high temperature has a greater impact on the plant, and fertilization can be stopped during this time, and when autumn comes, you need to chase a phosphorus and potassium fertilizer, you can choose Bika potassium dihydrogen phosphate.

Promotes the growth of its roots.

Third, the key points of fertilization in autumn.

When cultivating osmanthus, autumn belongs to the flowering period of osmanthus, and the flowering of plants has a very high demand for nutrients, and phosphorus and potassium fertilizers should be applied in time during this time. Before flowering, it is necessary to chase phosphorus and potassium fertilizer, which can achieve the purpose of promoting and preserving flowers. After the end of the flowering period, phosphorus and potassium fertilizer should also be applied once to prepare the plants for wintering.

Fourth, the key points of fertilization in winter.

Winter temperatures are very low, and osmanthus flowers enter the dormant period during this time, when the growth of the plants becomes very slow and the demand for nutrients is reduced. Therefore, it is necessary to reduce the fertilization of plants in winter, under normal circumstances, the fertilization after the end of the osmanthus flowering period can meet the growth of winter, and it is not fertilized during the wintering period.

Osmanthus fertilization is mainly divided into three periods, and nitrogen fertilizer should be applied once in about 15 days in the budding period of spring to make it better germinate and pull branches. In the summer flowering stage, a small amount of phosphorus and potassium fertilizer should be applied every week to make it bloom better, and in late autumn and early winter, a long-lasting base fertilizer should be applied to make it safely overwinter and continue to grow in the next year.

About how to fertilize osmanthus to grow better, it is generally necessary to fertilize three times according to its growth stage, which is in the budding period in spring, the flower bud germination period in summer and the overwintering period in winter, and it is necessary to fertilize in time to supplement its nutrition.

Generally, fertilization is carried out in the budding period of spring, and it is necessary to choose rotting cake fertilizer or nitrogen fertilizer, which is usually applied once in about 15 days, so that its young shoots can grow better and become stronger.

In the summer flower bud stage, it is necessary to apply an appropriate amount of phosphorus and potassium fertilizer, at this time, osmanthus needs to have enough nutrients to support its flower buds, so as to better and more flowering, generally need to apply a small amount of fertilizer every week, so that its nutrients are sufficient to wait for flowering.

In the winter overwintering period, a long-acting basal fertilizer should be applied, and in late autumn and early winter, it should be repotted and buried in the soil, so that it can provide enough nutrients for the osmanthus that has slowed down its growth rate, so that it can safely overwinter and wait for the next year to continue to grow.

Osmanthus every spring, can be applied every 10 days or so to apply nitrogen fertilizer, autumn can be applied every half a month to apply phosphorus and potassium fertilizer, in winter can be applied a rotten organic fertilizer, can also be used leaves, poultry, bean cake, peanut cake and other mixed fermentation to make osmanthus fertilizer, each fertilization should not be excessive, so as to promote the growth of osmanthus better.

Osmanthus is a plant that needs to provide it with a lot of nutrients to maintain, so how to fertilize osmanthus, osmanthus in the spring, can be fertilized every 10 days or so, fertilizer every half a month in autumn, fertilizer also needs to be applied in winter, and osmanthus does not need to be fertilized at other times.

Osmanthus generally mainly needs nitrogen fertilizer, followed by phosphate fertilizer and potassium fertilizer, generally the best nitrogen fertilizer in spring, phosphorus and potassium fertilizer can be applied in autumn, and a rotten organic fertilizer can be applied in winter, which can help osmanthus overwinter, and can also promote the growth of osmanthus flowers more vigorously.

Usually you can also make your own osmanthus fertilizer, we can use the leaves as osmanthus fertilizer, we can also mix poultry manure to make osmanthus fertilizer, we can also mix and ferment bean cakes, peanut cakes and other mixed fermentation as fertilizer, the nutrients of these fertilizers are also very good, which is conducive to the growth of osmanthus.

Every time you fertilize osmanthus, it should not be too concentrated, it is best to choose in the morning and evening when fertilizing, otherwise the temperature is too high and it is easy to burn the roots, affecting the normal growth of osmanthus, and the fertilizer applied to osmanthus needs to be rotted, otherwise the fertilizer will ferment in the pot soil, producing a large number of bacteria, so that the roots can not grow normally in the soil.

Osmanthus has a strong root system, strong germination, and vigorous growth, so there is a greater demand for fertilizer. When potting, a certain amount of solid fertilizer should be applied to make fertilizer, so as to be conducive to the later growth and meet its demand for fertilizer.

In addition to adding fertilizer when potting osmanthus flowers, fertilization during its growing season is also essential. At this time, it is necessary to water the liquid fertilizer with all elements, and the watering time is once every 10 to 15 days. Fertilization follows the principle of thin fertilizer and frequent application, and at the same time, the fertilizer should contain as much or more phosphorus and potassium fertilizer, so as to make the number of flowers more blooming and more colorful.
