What is the reason why the water raised roses are bowing their heads and wilting?

Excessive fertilization: It is particularly important to breed roses when fertilizing, some users are eager to make roses bloom, or they hear that the flowers of roses will be big and fragrant when they are fertilized, so they give roses a lot of fertilizer. However, too much fertilizer will only cause the roots of the roses to be burned, causing the leaves to wither without absorbing nutrients.

Lack of light: Plants must be exposed to light to increase the formation of chlorophyll, if the roses have been placed in a cool and ventilated position, then they will not be exposed to light for a long time, the leaves will show a withered yellow color, and then there will be wilting.

Precautions. When hydroponic roses are born, they need to change the water according to the four seasons, generally every 7 days in summer, once in autumn and half a month in spring, and once every 20 days in winter.

Secondly, the rotten roots and leaves need to be cut off every time the water is changed, so that the roses can grow well.

When the root system grows, the frequency of water change can be extended, about half a month, and once a week when the weather is hot. The temperature during maintenance should not be too high, around 18-25.

Reason 1: Due to the excessive evaporation of water in the sun, the root system cannot absorb enough water to maintain the freshness of the plant, so there will be wilting.

Reason 2: Many times the rose wilts are caused by the cold weather, and if it is frostbitten by the cold air, it will wilt because the roots are frostbitten and necrotic, and nutrients cannot be delivered.

Reason 3: Many times when breeding, you will forget to fertilize it, if there is not enough nutrients, the plant can not grow robustly, and there will be wilting.

Solution: 1. Replenish water in time.

Solution: Replenish it with water in time, water it, and then place it in a well-ventilated and cool place for a few days, and breed it in a sunny place.

2. Raise the temperature.

Solution: Move it to a warmer place as soon as possible and let it recover slowly. But don't put it in the sun or next to the heater right away.

3. Carry out fertilization.

Solution: Apply water and fertilizer to the roots of the plant to supplement its nutrients, or apply some rotten cake fertilizer, but you must water it a little to let it absorb better, and it will slowly recover.

You can try to cut off all the leaves and put them in a cool and ventilated place, you can also try to put them in a warm place to let him warm up slowly, or you can try to change some clean water and put some nutrients you need.

Place the roses in another shady place, change the growth environment, water and fertilize regularly, and put some nutrients in the water to keep the roses warm.

It may be that the temperature is not suitable, or there are no nutrients added to the water, or the temperature of the water is not correct, or it may be that there is a lack of sunlight, or there are bugs.

How to remedy the water raised roses is as follows:1. Change the water: change the roses with clean water and spray water mist on the flower branches.

2. Pruning: Prune off the yellowed and withered rhizomes and prune the petals.

3. Shading: Move the roses to a cool place for maintenance to reduce the time of strong light.

4. Ventilation: ensure indoor air circulation, and open windows for ventilation every day.

Add water to change the water, avoid exposure to the sun, and trim the hall in time.

Add water for water exchange: This can be caused by a lack of water or poor water quality. In a state of water scarcity, the branches of the flowers are unable to absorb water to supply the leaves and flowers, resulting in wilting.

Poor water quality can affect the freshness and wilting of flowers. If it is caused by water shortage, it needs to be replenished in time, and when the water quality deteriorates, the water needs to be changed immediately. Shading treatment:

Flowers are not tolerant to strong light. If they are exposed to bright light for a long time, they can accelerate the evaporation of water from the branches. If they cannot be supplied to the branches, they will wither.

It needs to be transferred to a semi-shaded environment for maintenance in time to ensure that the environment is ventilated and breathable. When the water in the shoots is full, it can gradually recover. Timely trimming:

Blockage of the branches at the base of the flowers affects the absorption of water by the branches, causing the branches to wilt. In addition, if there are many leaves on the branches, the amount of water evaporation will increase, which will also lead to wilting. The flowering branches should be plucked in time, the branches should be cut short, the upper part of the leaves should be pruned, and only the lower 1-2 leaves should be retained.

In general, the freshness time of flowers is about 7-20 days. Depending on the variety and maintenance method, it is normal for the flowers to wither after a period of maintenance, and the branches will not remain fresh for a long time.

Roses are gorgeous, there are many colors of roses, the most classic is red roses, red roses have always been a popular flower. Whether it is a water-raised or soil-grown rose, it is impossible to say that it will never wither, but it can only be said that it can be said to find a way to prolong its withering time. So how to raise roses in water without wilting?

1. Change the water regularly. After hydroponic roses have taken root, changing the water is even more important. In spring and autumn 15 days, summer 7 to 10 days, winter 15 to 20 days to change the water.

When changing the water, the container and the roots should be cleaned, because the inner wall of the container and the roots are very easy to absorb substances that are not conducive to the growth of the plant. When adding water, the root system needs to be exposed1 3 on the outside for normal respiration.

2. Ensure sufficient sunlight. Roses can not be placed in a place with insufficient light indoors for a long time, to ensure that there are more than 4 hours of direct sunlight every day, and it is recommended to put them indoors in a sunny place in winter to ensure their normal growth.

3. Maintain a suitable temperature. The most suitable temperature for indoor hydroponic roses is about 18 25, if the temperature exceeds 30, it is necessary to give the hydroponic roses a proper shade to cool down, because long-term exposure to high temperature nutrient aqueous solution can easily lead to root rot. In summer, it is necessary to prevent direct sunlight into the basin to avoid excessive water temperature, and in winter, it is necessary to prevent frostbite and keep it in a warm place indoors.

4. Prune and prune. Prune properly according to growth. Pruning should be done in autumn to prevent overgrowth, which will affect flowering and plant appearance.

For roses that have weakened growth and basically lost their ability to bloom, they can be re-pruned to promote the growth of new branches. Old branches that are more than 5 years old should be thinned in time to support the growth of new branches. Roses bloom, pick as they bloom, and then open again after picking, otherwise they will only bloom once.

5. Reasonable fertilization. When fertilizing hydroponic roses, be sure to apply a special nutrient solution, because roses are more sensitive to fertilizer in water, if it is not applied well, it is easy to affect the normal growth of plants, and special nutrient solutions can be purchased from flower shops, which are generally available.

6. Control pests and diseases. There are many aphids in roses, and we should pay attention to prevention and control. A small amount of aphids can be wiped off with tweezers or a rag, and if there are too many, it is recommended to buy drugs and use them according to the instructions.

Break a small piece of vitamin C, crush it, put it in water, or add a little sugar to the water, and then cut a small piece at the bottom of the received rose flower path and put it into the level where the "material" has been added. Spraying rose petals and leaves with a small watering can every day can can preserve the freshness of the roses.
