What should I do if the old roots of roses turn black and do not sprout?

If the old roots of the rose turn black and do not germinate, there are several ways to consider:

1.Check for moisture: If a plant is dehydrated, its roots may turn black and fail to germinate. Therefore, the plants need to be given enough water, but also be careful not to overwater.

2.Check for light: Roses need plenty of sunlight to grow and bloom properly. If there is not enough light, it may cause the plant to fail to germinate. Therefore, the roses need to be placed in full sunlight.

3.Check the soil: If the quality of the soil is not good, it may affect the growth of the plant. It is advisable to replace the soil with good quality so that the plants can grow and germinate properly.

4.Pruning old roots: If the old roots have turned black and can't germinate, consider pruning the old roots to allow the plant to grow back. Be careful not to harm the new roots when pruning.

5.Transplanting: If none of the above works, consider transplanting the roses into a better environment, such as more suitable soil and better light conditions.

It should be noted that the problem of plant growth needs to be dealt with patiently and carefully. During handling, the integrity and health of the plant is maintained.

If the rose turns black and does not sprout, you can give it a little more water. This facilitates his overall circulation.

On the other hand, you need to give it enough sunlight. This further promotes its growth. Wait patiently for a while for it to sprout.

Caused by overwatering, it can be remedied by placing the roses in a dry and ventilated place to speed up the evaporation of water;If you are infected with black spot disease, you need to cut off the infected branches, apply 1:1:200 Bordeaux solution to the wound, and spray the whole plant with carbendazim once a week for one month;If it is caused by insufficient light, it is necessary to place the rose in a sunny place for maintenance.

The black and dry branches of the rose may be due to excessive watering, the rose is more drought tolerant, not waterlogging, too much watering will lead to oversaturation of water in the soil, the roots of the difficulty in breathing, affecting the development of the branches, black and dry. At this time, the rose should be placed in a dry and ventilated place to speed up the evaporation of moisture.

The dry and blackened branches of roses may also be due to black spot disease, which can be caused by black spots on infected branches and leaves. This condition requires immediate cutting of the infected part, applying 1:1:200 of Bordeaux solution to the wound and spraying the whole plant with carbendazim once a week for one month.

If the amount of fertilizer is too high or the concentration of fertilizer is too high, the roots will be burned, resulting in the black and dry branches of the rose. It is necessary to cut off the rotten roots of the roses, and then place them in the new soil, and then apply 1000 times of the general fertilizer of Hua Duoduo once a week, and control it at 20ml 30ml each time.

The blackened and withered branches of roses may also be due to a lack of light, and roses obtain energy through photosynthesis. When the light is insufficient, the rose does not have enough energy to maintain the survival of the epidermal cells of the branches, and the phenomenon of blackening and dryness appears. At this time, it is necessary to place the roses in a sunny place for maintenance.

Rose buds may be improper watering of the plant during maintenance, resulting in water accumulation of the plant, or it may be too much nutrients provided for the rose during maintenance, resulting in fertilizer damage to the plant, or it may be that the rose receives too much light in the process of growth, resulting in burns of the plant shoots.

How to deal with the wilting when the rose buds grow.

1. Water properly.

Although roses are suitable for growing in a more humid environment, too much water is provided for roses when they grow flower buds, which will cause rose buds to wilt, so it is necessary to provide the right amount of water for roses in the later stage of maintenance, and it is best to provide water for roses when the soil is dry.

2. Reasonable fertilization.

Rose buds may wilt when they grow or they may provide too much nutrients for roses during maintenance, resulting in burns on the roots of roses, unable to absorb nutrients for flower buds to grow, so rose buds wilt, and need to provide an appropriate amount of nutrients for roses in the later stage of maintenance, such as trim fertilizer can improve the growth rate of plants.

3. Proper shading.

Roses are suitable for growing in a sunny environment, but when maintaining roses, the light provided for them is too strong, which will cause the leaves of roses to burn and wilt, so it is necessary to provide suitable light for them when maintaining roses in the later stage, and shade the roses in time when the light is too strong, so that the plants can grow healthily.

4. Pest control.

Roses suffer from insect infestation after growing flower buds, which will cause rose buds to wilt, so in the later maintenance of roses, it is necessary to spray the plant regularly to eliminate the existing pests on the roses, and at the same time, it is also necessary to prune the roses properly to improve the ventilation of the rose plants.

It may be that the weather is too hot, and the flower pot is overheated and hurts the roots, it is recommended to put it on the north balcony for proper shade, and the watering time is not right, so it is recommended to water thoroughly at night.

Extended Materials. Rose seedling maintenance.

1. Sow rose seedlings.

The sowing season for rose seedlings is in autumn, and in order to obtain good rose seedlings, you need to sand the seeds first. The specific method is to mix the sand with a small amount of soil, then add an appropriate amount of water to wet the mixture, and then put in the rose seeds. Then bury it in the ground and leave a hole in it, and when the next year the seed has broken out, we just need to plant it in a pot.

2. Buy rose seedlings.

If you feel that it is troublesome to sow seeds, it is also a very good choice to buy rose seedlings, but it should be noted that after the rose seedlings are bought, they should be unpacked and ventilated in time, otherwise their roots are easy to rot. Especially if you buy it from other places, some of the leaves may be dying when they arrive, and you just need to put them in water to let it replenish the water.

3. Choose good soil.

The vitality of roses is relatively tenacious, suitable for growing in moderately alkaline soil, and roses love the sun, and the location chosen is good to allow roses to have sufficient sun time. At the same time, roses need to have enough water, so after choosing a good plot, it is necessary to keep the soil moist, especially in summer, so that it can be watered every day.

4. Overwintering management.

Roses are very cold-tolerant, but when the temperature is low, it will stop growing, especially when it is below zero, and it is necessary to take cold protection measures, otherwise it is easy to freeze to death of rose seedlings. We can buy some bark shavings to cover the seedlings and wait for spring to get rid of them.

Precautions for planting roses.

1. Pay attention to pruning branches and leaves.

Roses have a strong ability to grow, especially before spring, properly cutting off some excess branches and leaves and diseased branches can make roses bloom more beautiful and moving.

2. Pay attention to sun exposure time.

Roses love the sun, so you can put them in a well-ventilated place with plenty of sun exposure time. But because the summer is very hot, in order to prevent sunburn, it is good to water the rose every day so that it can thrive.

3. Pay attention to fertilization, insect control and weeding.

Roses are the same as other plants, and they need to be fertilized, insecticide, and weeded frequently, so as to better ensure the texture of the flowers.

4. Pay attention to loose soil.

Roses are suitable for growing in loose soil, so you need to use a shovel to help loosen the soil frequently, and the action should be as light as possible to avoid injuring the rhizome, otherwise it will be troublesome. If you are too lazy to do it, you can also put some earthworms in it, the effect is better.

It should be that the temperature is too high, the transpiration is too large, and the water transpired out is far greater than the water absorbed by the roots, so this situation will occur. Place in a cool place and slowly increase the light after a week, so that it will be good to live.

Cultivation methods and precautions for roses.

1. Soil. Roses prefer soft and fertile soils, and sandy soils with good drainage properties are recommended. If clay soil with poor ventilation is used, the nutrients absorbed by the roots are insufficient, which can easily lead to poor growth and unsatisfactory flowering results.

2. Moisture. Roses are not waterlogged, but they are water-loving, and when the topsoil is dry, they should be watered to completely soak the potting soil. Be sure to avoid standing water, which can cause root rot for a long time.

3. Fertilization. Roses do not have very strict requirements for fertilizer, especially when the soil nutrients are sufficient. If the nutrients are insufficient, you can choose a water-soluble fertilizer rich in nitrogen, phosphorus and potassium, and the amount of top dressing should not be too much, and thin fertilizer can be used.

4. Illumination. The growth of roses needs sunlight, it is important to ensure sufficient light, it is best to have more than 4 hours of direct sunlight every day, and a long time in an unventilated and poorly lit place will cause problems such as yellowing of leaves. In winter, the outdoor temperature is too low, so it should be moved indoors to the window for maintenance.

5. Temperature. Roses need warm temperatures, preferably between 12 and 28 degrees Celsius, with a minimum temperature of -5 degrees Celsius. It is possible to increase the temperature difference between day and night to improve the ornamentation of the plants.

Reason: Around April to July, you may be infected with black spots, at first only small purple-brown spots appear on the leaves, and then gradually expand and become more serious, and in the later stage, the branches also have black spots, resulting in the distribution of black branches and branches.

Solution: The disease is mainly prevention-oriented, to sweep the fallen leaves in time, regularly spray foliar fertilizer to promote plant growth, reduce the chance of infection, if the disease occurs, it is necessary to spray.

Reason: Potted roses have more nutrient needs, but fertilization needs to be paid attention to, once there is too much fertilization, or the concentration of fertilizer is too high, it will cause the root system to be difficult to adapt, resulting in the root being burned out, making the root rot, and the branch part will also be blackened.

Solution: After finding that there is too much fertilization, it is necessary to stop it in time, prune the roots, and replant them in pots to promote the growth of new roots.

Reason: Roses are drought-tolerant and waterlogging-tolerant plants, and if too much water is applied, water will accumulate in the potting soil, causing roots to rot and branches to cause problems.

Solution: Promote the evaporation and discharge of water, and if the roots are rotten, they should also be treated.
