What is the best fertilizer for roses

Perhaps in other places, old farmers will only plant a few roses randomly for ornamental and decorative purposes, but in Yunnan in the southwest, not only does it have a natural climate of “spring all year round”, but it also has the largest rose garden in Asia. Flower Trading Market – Dounan Flower Market, which determines that roses can be widely planted by local farmers as a cash crop.
In the past two years, as the price of roses has been rising, more and more experienced farmers have begun to engage in rose cultivation. But careful people will always find that the roses grown by some people can be picked 4 times a year, while the roses they grow can only be picked 2-3 times. In fact, the number of times a rose can be harvested is mainly determined by the root system of the rose. In other words, only by allowing the root system of the rose to absorb enough nutrients can we ensure the number of harvests of the rose. The most direct way to allow the root system of the rose to absorb sufficient nutrients is Fertilize properly. So, how do we fertilize roses?
Experienced flower growers know that the fertilizing time and amount of roses need to be judged according to the growth status of the roses. Generally speaking, there are four types of fertilizers that must be applied to roses, namely:
1. Base fertilizer
2. Bud-promoting fertilizer
3. Leaf spreading fertilizer
4. Flower-preserving fertilizer

Base fertilizer

Roses are perennial plants, especially when planted in a large area, it takes 4-5 years to replace rose seedlings. By applying base fertilizer, we can meet the nutrient needs of roses throughout the entire period from budding to flowering, prevent roses from becoming deficient in fertilizer during their growth, and prevent roses from entering premature aging. It can be said: “Basic fertilizer is an indirect reflection of rose yield.” Therefore, when planting roses, you must apply sufficient base fertilizer.
Regarding the time to apply base fertilizer, it is generally before planting roses or after picking roses. The reason why roses need to be applied with base fertilizer after picking is because “every time a rose is picked, it will enter the next round of growth cycle”, which is the same as “the growth cycle of leeks”. Every time a crop is harvested, another crop will grow.” There are similarities. In other words, the number of times the roses are picked, the number of times base fertilizer needs to be applied. As for the choice of base fertilizer, decomposed farmyard manure is the best for the following reasons:
① Farmyard manure contains a large amount of mineral elements. Applying farmyard manure can save the trouble of applying micro-fertilizer to roses.
② Farmyard manure has a longer fertilizer effect, and one application of fertilizer can maintain the nutrient requirements of roses throughout their growth cycle.
③ Farm manure has a slow fertilizer effect. Freshly harvested roses need to recover. Once fertilizer with a fast fertilizer effect is applied, it will cause fertilizer damage. This is just like the reason why we cannot eat large amounts of food during a serious illness.
④Farmyard manure can enhance the permeability of the soil and loosen the soil, which is more conducive to the growth and development of the rose root system, and allows the rose root system to absorb enough nutrients, so that it can naturally grow.

★Although farmyard manure is the best fertilizer, if used improperly, it will have the opposite effect. Therefore, when using farmyard manure as base fertilizer for roses, you need to pay attention to the following matters:
① Farmyard manure must be fully decomposed to prevent farmyard manure from carrying pathogens and insect eggs, and to prevent farmyard manure from fermenting in the soil and causing fertilizer damage.
② It is strictly prohibited to use livestock manure with heavy feeds such as pigs, chickens, ducks, etc. as base fertilizer for roses. The reason is that these fertilizers contain a large amount of heavy metals, hormones, etc., and roses are sensitive to these substances.
③When applying farmyard manure to roses, it is best to combine it with watering. The combination of water and fertilizer will make the fertilizer more effective.

Bud-promoting fertilizer

Applying bud-promoting fertilizer to roses has two main purposes: one is to promote the differentiation of rose buds, make the roses differentiate early, grow early, and bloom early, and enable the roses to achieve “one plant with multiple branches”, which is a preparation for high yield. Preparation; the second is to promote the growth of the rose root system, accumulate more nutrients for the rose root system, and ultimately achieve the purpose of root nourishment and root protection. It can be said that “bud-promoting fertilizer is the guarantee of the yield of the current crop of roses.”
Regarding the application time of bud-promoting fertilizer, it is generally applied after the roses are harvested and before the flower buds differentiate. If the flower buds of the roses are sparsely differentiated, a second top dressing can be carried out within 10 days after fertilization. However, during the second top dressing, remember that the top dressing time cannot be too late, otherwise, the fertilizer will be wasted and the effect will not be achieved. The purpose of bud-promoting fertilizer is generally based on the fact that no differentiated leaves can be seen. As for the choice of fertilizer to promote sprouting, high-phosphorus type 10-43-10+1 (Mg) macroelement water-soluble fertilizer is the best for the following reasons:
① Water-soluble fertilizer dissolves quickly and can be quickly absorbed by roses after dilution, without burning the rose seedlings.
②The flower bud differentiation stage of roses has the highest demand for phosphate fertilizer. Sufficient phosphate fertilizer (43) can promote flower bud differentiation.
③Nitrogen fertilizer (10) can promote the growth of flower buds and help roses quickly expand their leaves.
④Potassium fertilizer (10) can improve the disease resistance of roses and reduce rose diseases.
⑤The growth of roses requires trace elements, which can prevent roses from suffering from magnesium deficiency (1).

Zhanye fertilizer

Applying leaf-growing fertilizer to roses has three main purposes: first, to promote the growth of rose plants and make the rose plants grow stronger, so as to improve the utilization rate of rose buds; second, to promote the growth of rose leaves and make the leaves Accumulate nutrients through photosynthesis; third, prevent rose plants from lodging, bud breakage and other phenomena during the growth process, thereby achieving the purpose of increasing rose yield.
Regarding the application time of leaf spreading fertilizer, it is generally applied before the flower buds of the roses are differentiated and the “tops” are formed (before the flower buds are seen). Since roses require a higher amount of fertilizer after flower bud differentiation, which is the period during which they require the highest amount of fertilizer during their growth, rose leaf spreading fertilizer needs to be applied 3-5 times according to the growth of the plant, before and after fertilization. The interval generally does not exceed 2 weeks. As for the fertilizer selection for leaf spreading fertilizer, the balanced 19-19-19 macroelement water-soluble fertilizer is the best for the following reasons:
①A variety of nutrients are applied to better meet the fertilizer needs of roses.
② Nitrogen fertilizer (19) promotes the vertical growth of rose plants.
③Phosphate fertilizer (19) promotes strong rose plants and developed root systems, and prevents roses from growing too long.
④Potassium fertilizer (19) prepares for the formation of rose buds and increases the number of petals.
★When the rose plants grow slowly, stable nitrogen fertilizer can be applied appropriately to promote the growth of the rose plants and ensure that the roses can grow to a suitable picking height before the buds are formed.

Preserved flower fertilizer

Applying flower-preserving fertilizer to roses has three purposes: first, to promote early flowering and early market of roses, and to prevent roses from not blooming; second, to increase the weight and thickness of rose petals, thereby improving the quality of roses and preventing roses from being transported during transportation The petals will fall off; the third is to enhance the resistance of roses to diseases and insect pests, and prevent roses from developing diseases and insect pests such as white powder and red spider mites. It can be said that: “leaf spreading fertilizer is the guarantee of the quality of roses.”

After you see the “top” of the rose, you can start to apply flower-preserving fertilizer.

Regarding the application time of flower-preserving fertilizer, fertilizer can generally be applied after the roses have grown “tops” (buds). Under normal circumstances, flower-preserving fertilizer needs to be fertilized twice in a row, and the interval between fertilization should not exceed 10 days. When applying fertilizer for the second time, you need to pay attention not to apply it too late, generally when the flower buds are obviously enlarged. If the second top dressing is carried out after the petals are formed, the purpose of fertilization will not be achieved. As for the choice of flower-preserving fertilizer, high-potassium 10-8-40+1 (Mg) macroelement water-soluble fertilizer should be the best for the following reasons:
① The flowering period of roses has the highest requirements for potassium fertilizer. Sufficient potassium fertilizer (40) can improve the disease resistance of roses and improve the quality of rose petals.
②Nitrogen fertilizer (10) maintains the growth of rose plants and prevents rose plants from withering during the flowering period.
③Phosphate fertilizer (8) meets the nutrient needs of the rose root system and prepares for the next flower bud differentiation.
④Rose petals require trace elements. Supplementing magnesium (1) can improve the quality of roses.

What should you pay attention to when fertilizing roses?

① Roses like fertilizer, but they are sensitive to fertilizers. Therefore, broadcast compound fertilizers should be used with caution. It is recommended to use water-soluble fertilizers instead.
② When fertilizing roses, pay attention to “apply thin fertilizer and apply more fertilizer” to prevent root burning caused by excessive fertilization at one time. Therefore, it is recommended that the amount of fertilizer applied per mu of the above fertilizers is 5-10KG/time.
③ During the fertilization process of roses, remember not to apply too much nitrogen fertilizer, otherwise, the roses will not only appear leggy, but also suffer from serious diseases and insect pests.
④ It is recommended to fertilize roses in sunny weather, and try to avoid rainy weather to prevent the fertilizer effect from slowing down.
Of course, planting roses is not as simple as imagined. During the growth process, inadequate treatment of pests and diseases, improper temperature control, insufficient light, etc. will also affect the number of rose harvests.

Expanded information:

Roses are loved by people in many areas, especially between lovers. Roses are fragrant and perfect for creating a delicate and beautiful flower wall in the courtyard. Garden roses generally bloom only once a year. If you don’t care for them well, you will have to wait until next year to see beautiful roses. In the process of rose maintenance, fertilizing is a very critical step.

Soil base fertilizer:

When planting roses in the courtyard, if they are grown in pots, the soil in the pots needs to be filled with sufficient base fertilizer, and then the roses need to be repotted and soiled every two years. Soil base fertilizer can be made from a mixture of cake fertilizer and vegetable leaf fertilizer. This can provide sufficient nutrients for roses in a timely manner and prevent them from stunting due to nutritional deficiencies.

Fertilizer selection:

After determining the soil base fertilizer, during the growth process of the rose, we also need to apply some decomposed organic fertilizer or nitrogen, phosphorus and potassium compound fertilizer to it. But if the roses in the garden are attacked by diseases and insect pests, you should apply more potassium fertilizer, because potassium fertilizer is very effective in preventing and controlling diseases and insect pests. If you find that the roses are growing slowly, you should apply more nitrogen fertilizer.

Fertilization time:

Roses are a plant that loves fertilizer. Friends who grow roses need to fertilize them frequently. In spring and autumn, when roses are in the growth stage, fertilizer can be applied to roses every 15 to 20 days. However, in summer and winter, roses will stop growing, so there is no need to fertilize them at this time.

Fertilization precautions:

When fertilizing, we must be careful not to over-fertilize, otherwise the roses will have roots burned, resulting in leggy branches, root rot, yellowing of branches and leaves, etc., and may be infected with various diseases. Pests and diseases. In this way, even if you build a rose wall, it will not improve the beauty of the courtyard.
