What if the carnation leaves turn yellow? it is important to add fat and water to the sun / pruning.

Mother's Day is coming. Have your carnations blossomed yet? It may be very easy for people who can raise carnations to blossom. Friends who will not just start to grow will probably encounter a lot of problems. For example, if the leaves turn yellow, what about the yellow leaves of carnations? In fact, it is very simple to find the cause of the yellowing of carnation leaves, and then solve it. Common methods are fertilizing, basking in the sun, pruning and so on. Let's go and have a look.

I. the causes and solutions of the yellowing of carnation leaves

1. Too much or too little watering

In the cultivation of carnations, we introduce that watering is very important, and one of the reasons for the yellowing of carnation leaves is inappropriate watering, that is, too much or too little watering. If you water too much, the flowerpot will be in a state of stagnant water for a long time, the root of the flower is likely to rot, and the leaves will turn yellow; if you water too little, because you cannot absorb water, the leaves will dry up and turn yellow.

Solution: if the leaves are yellowing caused by improper watering, we can move the basin to a cool area, do not add fertilizer, and carefully control watering. If the basin is not dry, do not sprinkle water, should be diligent in loosening the soil, so that the root breathable.

2. Improper light and temperature

When the temperature is higher than 30 ℃, the leaves dry easily and turn yellow. If there is not enough light, the leaves can not breathe and photosynthesize, so they will turn yellow.

Solution: the temperature suitable for the growth of carnations is 13-25 ℃. Sunlight needs 6 to 8 hours a day. Love light is its characteristic. No matter which area of the room you put it, make sure that the sun can shine on it, so that it will grow well.

3. Soil alkalinity.

Soil is one of the most important links of potted carnations, and it likes a little sour soil, so if you often water it with alkaline water or the soil that grows flowers also has alkaline flowers, the leaves will naturally be hurt and yellowed.

Solution: if the leaves of this flower turn yellow during the growing period, the nutrients are more likely to be alkaline. 0.2% alum can be added, and the leaves will turn green soon. If it is yellowing during normal growth, it may be that too much watering has rotted away the roots.

4. The flowerpot has not been changed for a long time.

If your carnation has been bought for a long time, the flowerpot and soil have not been changed, and the leaves have turned yellow, it is likely to be caused by not changing the flowerpot for a long time. In this way, the nutrition of the flowers can not keep up, and there is not a lot of nutrients to be absorbed by the roots, so the leaves will lack nutrients.

Solution: flower friends need to change the soil properly, and if it takes a long time, they also need to change pots, so that the carnations can be nutritionally balanced and the leaves will not turn yellow.

5. Pruning depends on the time

The carnation leaves are yellow, they must be cut off, but after it is restored, all you need to do is to clean the yellow leaves at the bottom and never cut and hurt the roots. As for how to trim carnations, we will introduce the specific methods below.

Second, how to trim carnations

Many people have carnations, but they don't know how to trim them. In fact, it should be trimmed in different ways according to the time. For example, in its growing period, in order to remove the apical advantage and make it grow more luxuriantly, we can choose to top it; in the bud stage, we can cut off some buds to improve the quality of the flowers; after flowering, we can cut off the pedicels to help it grow better. The specific pruning methods of carnations are as follows:

1. Top pruning

The top of most plants has an advantage, and the top buds grow first, which limits the growth of lateral buds, so we choose to go to the top in order to make the plants more luxuriant and increase the number of flowers. Carnations also belong to this kind of plant, which is topped and pruned twice:

The first topping is to choose when the plant grows 8 to 9 pairs of leaves, this time only need to leave 4 to 6 pairs of leaves

The second topping should be carried out when more than 4 pairs of leaves grow on the side branches of the plant, this time leaving only 3 to 4 pairs of leaves on each side branch. Finally, the whole plant has 12 to 15 lateral branches.

2. Pruning buds during pregnancy

When carnations grow into flowers, we only need to keep the front end of each side branch, and the rest can be removed. This can ensure the bright color and large shape of the flowers, improve the quality of flowering and increase the degree of appreciation.

3. How to trim the flowers of carnations

For this problem, we should pay attention to the fact that the pedicel should be cut off immediately after the carnation blossoms for the first time. This helps plants continue to blossom and reduce the loss of nutrients.

What the editor would like to remind here is that if a novice grows flowers, you don't have to be careful when pruning, and don't overrun love and don't have the heart to prune. The carnation has great vitality, so even if it is trimmed wrong, it can slowly grow back. But without rest, carnations can not blossom normally, and then it will be too late to regret. The above is all about the pruning of carnations and the yellowing of carnations leaves. I hope I can give you some help.

How to cultivate Carnation in Aquatic Culture methods and points for attention of Carnation Culture

Carnation is a common flower plant, it is rich in color, if the growth environment is suitable, it is possible that it will bloom for four seasons. Many people raise carnations, but most of them grow carnations in pots. In fact, it can survive not only in the soil, but also in the water. Let's learn about the hydroponic culture of carnations.

How to raise carnations in water

1. Prepare a vase or other container and inject the right amount of water into it. In order to make the flowers bloom longer, you can also put a little beer in the vase, or add a small amount of sugar and aspirin to the water.

2. Check the leaves above the bouquet and cut off all the leaves that may be immersed in water.

3. Cut the base of each carnation stem in the bouquet with scissors, and then insert it into the water.

4. It is best to spread the bouquet so that there is good ventilation between the branches. If you must keep the bound ribbon on the bouquet, it is recommended to loosen it and not tie it too tightly.

5. If you want the carnation to blossom early, you can prune the branches and put them in warm water solution so that the flowers can bloom a few days earlier.

Methods and matters needing attention in hydroponic Culture of Carnation

1. Pruning

The branches should be cut 35 mm below the node, and the cut should be flat and free of cracks. Remove the leaves under the mouth of the bottle, and there should be a certain interval between each flower to ensure smooth ventilation. Its growth time is from December to February of the following year, and it only takes about 30 days to take root.

2. Watering

Wipe it clean before putting it into the bottle. The water should be less than half of the root, and part of the root should be exposed outside the water. If it is a new flower, the root wound is more, it is easy to rot, so often change the water, at the same time to wash the bottle and flower root.

If it is hot and hot, the amount of oxygen in the water will be reduced, its breathing will be faster, the oxygen will be used up quickly, and the water should be changed more frequently, preferably every day, until the white roots grow in the water can slowly reduce the number of times to add water.

If the water in the bottle volatilizes from 20% to 30, you can add water. Don't add too much water. You still have to expose part of the root to the surface. If it is the spring and autumn season about half a month to renew the water, if it is winter, about 20 days to update once.

3. Fattening

Because it is hydroponic, the added fertilizer will melt in the water, and once its proportion exceeds the need for flowers, it will have an adverse effect. It is best to buy a special nutrient solution, which is based on the proportion of flowers, which is very scientific.

4. Lighting

It likes the sun better, if it is the period when the seedlings are just growing or the flowers are in full bloom, don't put them under the bright light. At other times, you don't have to worry that the strong light will hurt it.

5. Temperature

It likes cool temperatures. In winter, if the temperature is lower than nine ℃, growth will stop. In summer, if the temperature is higher than 35 ℃, it will be injured. So it should be cooled down in summer and wrapped in plastic film in winter.

Potted carnation

Carnation is also known as carnation and musk carnation. It is an evergreen subshrub of Caryophyllaceae and Dianthus. It is herbaceous when young and is often cultivated perennially. The plant height is 30 cm to 60 cm or more, and the stems and leaves are smooth. The whole body is covered with white powder, and the base of the stem is often lignified. Leaves opposite or whorled, linear-lanceolate, thick, entire, base clasping, grayish green. Flowers are usually solitary or 2 to 5 clustered branches with white, water red, purple, yellow, creamy yellow, orange and other colors, with fragrance, bracts 2 to 3 layers, close to the calyx tube, calyx tube tip 5-lobed, lobes broadly ovate, petals numerous, single or double, the apex is wrinkled and wavy. Fruit a capsule, seeds brown. The natural flowering period is from May to July, the cut flowers can be produced annually in greenhouse cultivation, and the winter flowering period is from January to February.

The so-called carnation mainly refers to the four seasons flowering carnation planted in greenhouse or potted. Under good and moderate cultivation conditions, it can blossom for several years and Lignification at the base of the stem. These varieties are mainly bred in the United States. Carnation is native to southern Europe, the Mediterranean coast to India. Sexual preference for fresh air, dry and sunny environment, requires rich in humus, strong conservation, slightly clayey soil, but must be well drained. Avoid continuous cropping. Summer should be cool, not resistant to hot and humid. The suitable temperature for growth is 15 ℃ to 20 ℃, and the night temperature in winter is 7 ℃ to 10 ℃. There are some differences in temperature requirements among different varieties, such as yellow varieties, the suitable temperature for growth is 20 ℃ to 25 ℃, and the suitable temperature for flowering is 10 ℃ to 20 ℃, while for red varieties, the requirements are higher, and when the temperature is lower than 25 ℃, the growth is slow, even can not bloom.

In large-scale production of carnation, virus-free seedlings are usually cultivated by tissue culture as female parent, and then propagated by cutting method. The best cutting time is from January to March, especially from late January to early February in the middle greenhouse. Cuttings should be selected mother plant apical bud diameter has grown to 1 cm, in which the lateral buds grow to 4 cm to 6 cm by hand, the action should be quick, its part with some heel, so easy to survive. Cuttage containers are used with cuttings or seedling pots, and the substrate is made of plain sand. The cutting depth should be 1 cm. After cutting, first put the scattered light in the greenhouse near the heat source, keep the substrate temperature about 20 ℃, and promote rooting. Initially, spray water once or twice a day with a fine spray can. After sprouting new shoots for about one month, new roots were sent out in the lower part, moved to the sunny place, dry watering, moderate ventilation and application of dilute liquid fertilizer. At the end of April, the seedlings were moved to the open field for maintenance.

In open field cultivation, sandy soil areas with high dry terrain and waterlogging prevention should be selected as beds, leveled and raked fine, applied sufficient basic fertilizer, and then planted seedlings. The row spacing of the plant was 10 cm × 10 cm, and the row spacing was 20 cm × 20 cm after about 1 month. Usually see dry watering, often ploughing and weeding. When the plant grows 6 to 9 pairs of leaves, remove the top tip from above the fourth pair of leaves. Usually leave 2 lateral buds and remove the rest. Wait for the lateral buds to develop into branches and pick the heart again, keeping each plant with 7 to 9 neat lateral branches, flowering in winter. It takes 5 to 6 months for the shoots to blossom after coring, which can regulate the flowering period.

When the temperature rises in summer, the plant growth is getting weaker and weaker, so fertilizer should be banned. When the Beginning of Autumn turns cooler with the weather, he can gradually apply thickened liquid fertilizer for 4 to 5 times. At this time, it grows faster, in order to concentrate nutrients for the flowering of the main branches, the lateral buds growing on each branch and the later germinating lateral buds should be removed, and the two lateral buds at the base of each branch can be properly retained, so that after the flower head of the main branch is cut off, the lateral buds germinate new branches and bloom again.

At the beginning of October, the soil with enough soil was transplanted in the greenhouse, or potted indoors. The border soil should be fertilized deeply in advance and sterilized, keep 15 ℃ to 20 ℃ at room temperature, and strictly prevent the temperature difference between day and night from exceeding 8 ℃. Pay attention to ventilation, keep enough light, blossom one after another from January to February, and the flowering period can be extended from May to June. Carnation Xi Qin fertilizer, in addition to basic fertilizer, in the formation of flower buds, but also need to apply liquid fertilizer several times, can be used alternately with organic liquid fertilizer and 0.3% potassium dihydrogen phosphate solution. After the plant grows tall, it is easy to lodge, so it should stand a stick or set up a grid to make it grow in the grid, which is not only conducive to ventilation and light transmission, but also has straight branches and neat and robust growth.

Family potted carnation, spring seedlings can be planted with high humus content of the gentleman orchid soil and plain sandy soil are half mixed with fine, the upper inner diameter of 10 cm of small basin maintenance. After two coring, the plant grew and enriched, and in mid-July, the fertilised culture soil was replaced with a pot with an inner diameter of 20 cm, and some broken basin slices were padded at the bottom of the basin as a drainage layer, with a small amount of long-acting base fertilizer. Put windbreak and rain shelter in midsummer, shade and cool places to avoid drought and waterlogging. Change the basin once every spring, pruning moderately. Follow its habits and carefully take care of it, which can be watched for many years.
