What to do if you put too much desert rose fertilizer and start to die buds

If you put too much fertilizer, you will burn the seedlings. It is advisable to change the soil as soon as possible. Desert roses are often propagated by cuttings, grafting and striping, and can also be sown.

Cuttings, the best in summer, select 1-2 year old branches, the top branch is the best, cut into 10 cm long, wait for the incision to dry and then insert it in the sand bed, about 3-4 weeks after the cutting. Grafting, using oleander as rootstock, in the summer using the splitting method, after the plant grows robust and easy to flower. Stripping, often in summer, using the high-altitude stripping method, cut off 2 3 on the strong branches, first fill with moss and then wrap with plastic film, about 25 days to take root, 45 days after cutting the potted plant.

Sowing in summer, germination temperature 21 .

Causes of yellowing of desert rose leaves:

1. Not long after I bought it, it is in the adaptation period, and a small amount of yellow leaves is normal and common.

2. The pot is not breathable, and the pot has large roots to avoid long-term moisture of the potting soil, resulting in root rot.

3. When the temperature is low, it will be in a dormant period in winter, that is, the leaves turn yellow and fall off, or even fall into a bare rod.

4. It is more drought-resistant, and the amount of water can not be too much each time, if there is more water, it is easy to cause root rot and cause leaf yellow.

5. The sun is too shaded, but remember not to expose to the sun, the leaves are also easy to yellow, and affect flowering.

6. Poor ventilation and insufficient light will inevitably cause yellow leaves, and in severe cases, the whole plant will rot and die.

7. If there is too much fertilization, it should be fertilized in an appropriate amount, and not too much.

8. There are earthworms or needleworms (red spiders, beetles) and other pests in the potting soil, and the symptoms of leaf yellow will also appear.

9. Leaf spot disease and root rot are harmful, and a large number of leaves can fall off when leaf spot disease is serious.

Finally, special attention should be paid to the fact that watering should be controlled and fertilization should be suspended, regardless of whether it is in the adaptation period or the dormant period. When a large number of new sprouts sprout in spring, top dressing is supplemented according to the growth situation.

In winter, it can be placed in a sunny location and keep the potting soil dry, and the minimum temperature should not be lower than 8. In other seasons, it can be placed in the sunlit area, not placed in the shade for maintenance, otherwise even if the watering and fertilization are normal, the yellow leaves will fall off due to less light.

Add a little new soil to neutralize it, take a portion of the soil to plant more flesh, and use the rest later.

When the desert rose rots its roots, it needs to be removed from the flower soil and washed off with clean water. Then use a sterilized knife to cut off the rotten roots, apply a layer of carbendazim powder to the incision, and let it dry. When it is completely dry, replant it in new flowering soil and place it in low light, and after a week it will be able to grow new roots.

1. Depotting. When you notice that a desert rose has rotten roots, the first step is to remove it from the pot. If its root system and the flower soil are tightly combined, if it is difficult to take, you can use a small shovel to loosen the flower soil around it, and then take it out whole.

2. Root trimming. Wash the roots of the plant with water, wash off all the soil, and then cut off all the rotten parts. Before cutting, treat the knives with a fungicide to prevent bacteria on them from infecting the plants. After cutting, apply a layer of carbendazim powder to the incision to sterilize.

3. Dry. Place the treated plants in a well-ventilated place to dry. After about 20 days, the carbendazim powder is completely dry and it is ready to be re-potted.

4. Put on the basin. Prepare some flower soil with good air permeability, put it in the flower pot, and then put the plants in the flower soil and compact the soil surface by hand. Finally, put it in low light, and after about a week, it will be able to grow new roots. For rooting and root care, you can choose to chase the root rooting agent of Woye Root.

After the desert rose root rot is treated, there is a high probability of survival.

1. Depotting and pruning.

If the roots of a desert rose rot, it needs to be removed from the original culture medium and gently washed with water to remove all the dirt from it. Then prepare a handle pruning shears and treat them with disinfectant, and cut off all the rotten roots on the plant, as well as the dead branches and yellow leaves that appear due to rotten roots.

2. Disinfection and soil preparation.

Prepare some disinfectant medicine, pour it into a small basin, and pour some water into it to dilute the liquid. Then put the plant in the solution, soak for about 30 minutes, and then take it out to dry. During this time, it is also necessary to prepare some new flower soil with humus and fine sand to replace the old soil in the pot.

3. Replanting and maintenance.

Place the dried plant with its roots facing down in the prepared new soil so that all its roots are below the surface of the soil. Then move the pot to a place with a relatively soft light and a temperature of around 20, and slowly maintain it for a while. Do not apply fertilizer during this period, but spray a little water when the soil dries.

This way, after about 7-10 days, it will be able to grow again. After that, use Bika water-soluble fertilizer in small quantities and many times.

Desert Rose ignores 1 point and causes severe root rot, and the following is how to save it.

From its name, we can clearly see that it is extremely drought tolerant, so when raising, there is no need to water too much, if you have too much water, it will be easy for it to rot roots.

Solution: Once the roots are rotten, they should be removed from the flower soil, carefully inspected, cut off the roots that have rotted and blackened, and then plant them in the new flower soil, and control the watering. If the flower soil is insufficient, you can put the old flower soil in the sun to dry it, steam off the moisture, and then mix it with a small amount of new flower soil.

We all know that any plant breathes by its roots, and if your flower soil, the sand and gravel you choose is too heavy and too dense, it will directly affect its roots, so that the roots cannot breathe normally, and if you encounter the wet weather in spring, it is not surprising that there are rotten roots.

Solution: At this time, we also need to cut off the rotten roots in time, and also replace the flower soil. Generally, it is best to mix peat soil, smelting, nutrient soil and other proportions, and then apply appropriate phosphate fertilizer to ensure its normal growth.

When raising it, if you accidentally apply chicken manure to it, it will be easy to mold and produce bacteria, and then the bacteria will flow to the roots, and when it gets wet, it will cause root rot.

Solution: In this case, we also need to remove the broken and replace the soil, and then pay attention to the use of flower fertilizer, and do not use chicken manure anymore.

Desert rose root growth period can apply a small amount of phosphate fertilizer, try to choose ordinary fertilizer do not use quick-acting fertilizer, this period of desert rose has not yet fully rooted, its root system is not developed, so the absorption rate of fertilizer is slow, the use of fast-acting fertilizer will lead to excessive soil nutrient content, causing certain fertilizer damage to the root system.

1. Ordinary phosphate fertilizer

Phosphate fertilizer can promote the growth and development of the root system of desert rose, can make its root system more robust, pay attention not to use fast-acting phosphate fertilizer, the nutrient content of fast-acting fertilizer is too high, it is easy to cause too much soil nutrient content, the plant has not yet taken root, can not completely absorb nutrients, easy to cause fertilizer damage, damage the root system of the plant, affect the normal growth and development.

2. Watering requirements

Desert roses grow drought-tolerant, watering should not be too much, to follow the watering principle of watering is watering thoroughly, see dry and wet, watering as far as possible round the edge of the pot to ensure that the soil is fully soaked, remember not to water from the top of the plant, it is easy to cause a lot of water to accumulate on the leaves and can not evaporate, which will lead to yellow leaves in the long run.

3. Light and temperature environment

Desert rose growth needs proper light, if the light is not enough, the leaves are easy to yellow and the flower type is loose, it can be placed on the balcony or in the yard with light contact for maintenance, when the temperature is too strong in summer, it can be properly shaded to avoid strong light burning the leaves, the temperature changes greatly in winter and spring, and it should be moved to indoor maintenance.

4. Potting soil selection

To plant desert roses, choose loose and fertile sandy soil with good drainage and air permeability, you can use humus, garden soil and sand and gravel to fully mix and add a small amount of nutrient solution, which can be sterilized and disinfected in the soil before planting, which can effectively avoid the bacteria in the soil from causing damage to the roots of the plants.

Desert roses do not germinate for reasons.

In general, desert roses cultivated in different regions have different germination times. Desert roses cultivated in the south generally sprout from the end of March to mid-to-early April each year, while those cultivated in the north are delayed by a month, and germination is only at the end of April and early May each year. The reason why roses do not germinate in the desert may be because they have just been transplanted and not potted, or they may be due to improper maintenance, such as too much watering and insufficient light.

Sand finger picks desert roses do not germinate treatment method.

Desert roses generally germinate four or five days after seed transplanting in the spring, but if they are not properly maintained after planting, they will affect their normal germination, or even no germination. If the roots of roses in the desert do not sprout due to excessive watering, the pots should be removed, the rotten roots of Wei Chanchang should be cleaned up, replanted in suitable pots, and then properly watered. If the desert rose does not germinate due to lack of sunlight, the plant should be moved to a sunny area for maintenance to ensure adequate sunlight, but if the sun is too strong, proper shade should be given.

Desert roses are maintained after germination.

Desert roses need to be watered properly after germination, generally more watering in spring, and timely fertilization to ensure sufficient water and nutrients to promote their growth.

Desert roses are usually fertilized better in spring and summer, mainly phosphorus and potassium fertilizers, and should be watered after sprinkling fertilizer, which helps to better absorb nutrients and make the plants grow vigorously. Ensure that it has sufficient light time in the usual maintenance, the ambient temperature shall not be lower than 10, and then water when the soil surface is drier, and pay attention to the prevention of pests and diseases.

Many people maintain desert roses, but do not know when it is better to fertilize desert roses, desert roses do not have a large demand for fertilizer, usually only in the spring and summer growth period need to apply fertilizer, every two years when changing pots can also be properly applied fertilizer, can make the branches and leaves grow luxuriant, flowering gorgeous.

Desert rose in spring and summer is the vigorous growth period, so water and fertilizer should be sufficient, desert rose prefers phosphorus and potassium fertilizer, when applying fertilizer, this can be the main, and then add some base fertilizer appropriately, after spreading fertilizer, you can carry out a watering, which helps plants to better absorb nutrients, and should stop spreading fertilizer in winter.

Desert roses should not be placed in a damp and dark location to maintain, should ensure that it has sufficient light time, it is best to place it outdoors for maintenance, the best temperature for growth is between 18 30, if the ambient temperature is lower than 10, it will stop growing, and the phenomenon of leaf yellow and leaf fall may occur.

Desert roses are tropical plants, so they should be watered when the soil surface is relatively dry, and the pot should not be watered, and the frequency of watering should be reduced in winter. Attention should also be paid to the prevention and control of pests and diseases during the growth period, carbendazim solution can be sprayed for prevention, and if pests and diseases have occurred, the corresponding drugs need to be sprayed according to the specific situation**.
