When does Magnolia blossom and its leaves turn yellow?

Magnolia magnolia maintenance still needs to be more careful in order to blossom. When will Magnolia bloom?

Magnolia mandshurica usually blossoms from April to June, and it is more common from mid-April to early May. Magnolia flowers early and late, in the same tree can see the various forms of flowers, some shy, green buds fresh and lovely, some just blooming, a few little bees can not wait to get in. The magnolia in full bloom is as white and tender as a baby's smiling face, sweet, pure and lovable. From a distance, a Magnolia magnolia looks like a big family with generations living together.

What if the leaves of Magnolia turn yellow:

1. The yellowing of Magnolia leaves is due to lack of light.

In the cultivation of Magnolia magnolia, there is a certain demand for light, if the light is not enough, Magnolia magnolia can not get light for a long time, it will cause its leaves to turn yellow. Pot culture of Magnolia magnolia, it is easy to occur this situation.

When cultivating Magnolia magnolia in pots, we must meet the light needs of Magnolia magnolia and give it sufficient light.

2. The yellowing of Magnolia leaves is due to low humidity in the air.

Magnolia needs appropriate humidity, if the humidity in the living air of Magnolia magnolia is too low, it will cause the air to be too dry, which will also make the leaves of Magnolia yellow.

If Magnolia magnolia is cultivated in northwest China, this phenomenon is easy to occur because the air is relatively dry. For breeding Magnolia magnolia, in order to avoid the yellowing of its leaves, it is best to maintain appropriate air humidity.

3. The yellowing of Magnolia leaves is due to overwatering.

When cultivating Magnolia magnolia, watering is also very important, because if Magnolia magnolia is watered too much, the soil is too moist or stagnant water is produced, which will cause the root system of Magnolia magnolia to rot, making it unable to absorb water and nutrients normally, thus causing its leaves to turn yellow.

Therefore, in the culture of Magnolia magnolia, watering must be appropriate, not too much.

4. The yellowing of Magnolia leaves is a problem of fertilization.

In the cultivation of Magnolia magnolia, fertilization is also a very important step, too little fertilization, or do not change the soil for a long time, nutrients will be relatively lack, resulting in its leaves are very thin and yellowing. Therefore, when breeding Magnolia magnolia, fertilizers should be applied in time, and the basin soil should be changed regularly.

If too much fertilizer is applied, it will lead to the thickening of the new leaves and the yellowing of the old leaves, so it is necessary to stop fertilizing and increase watering at this time.

The reason for the yellow leaves of Magnolia magnolia is solved.

Magnoliaceae Magnolia, Magnolia and Michelia

Have written about magnolia, it is necessary to write about several other common magnoliaceae plants, most of the flowers and colors are light and elegant, each has a clear fragrance, all very good!

Magnolia magnolia

Magnolia, I still quite like its fragrance, every May or June, it blossoms, very pure white, the flower shape is very huge, really as big as a bowl, but because the leaves are too gorgeous and dense, the huge flowers dotted sporadically are inconspicuous. Do not know when and where to get the information, has been mistaken for Magnolia Magnolia is the city flower of Shanghai, in fact, the city flower of Shanghai is Magnolia magnolia. On the contrary, the city tree in my hometown Changzhou is this magnolia. In addition, a misunderstanding was found. Zhang ailing wrote that she was imprisoned at home by her father and saw a white magnolia outside the window. She said that it was like waste paper and discarded waste paper. She did not like Magnolia magnolia. In fact, it was more likely that Magnolia Magnolia in early spring, tall and tall, must be able to reach her window on the second floor. The florescence is also long, and the white flowers gradually turn yellow and still stick to the branches. Gradually it became what Aileen looked like.

The bud is also huge.

Magnolia: Latin scientific name: Magnolia GrandifloraLinn.

Magnoliaceae, Magnolia plants. Very tall trees, it is said that in the origin of America can be as high as 30 meters, Shanghai community and road green belt is also often used this kind of tree, 30 meters have not been seen, 4, 5 meters are always there, especially tall and plump, evergreen four seasons, leaves are also large, leathery thick, very oily kind of dark green, just because of environmental pollution, often stick to ash. Of course, this is also one of the advantages of this kind of tree, which can resist smoke and wind and absorb dust and toxic gases in the air. It is obviously inappropriate for us to dislike the fact that others have sacrificed their beauty for the sake of the environment.

Magnolia magnolia is also called "Magnolia Magnolia" in some places because its flowers are huge and resemble lotus flowers. The fragrance is so rich and elegant that even if there are only a few blossoms on the tree, you can smell it from a distance. In fact, close, the fragrance is still the same, and it will not be thicker because of the proximity.

The tree is too tall, the flowers are not easy to shoot, a few far away, there have been no satisfactory pictures. You can't move a ladder to climb a tree in order to shoot flowers. At this time, I would think of Aileen's little building, Magnolia, which could be photographed from the window on the second floor.

Magnolia and other magnoliaceae plants, like light, seedlings need to be shady, like warm and humid climate, it and Magnolia, relatively hardy, Beijing, Lanzhou and other places can be planted outdoors.

The leaves of the seedlings are still soft.

White orchid

Every year in early summer, the gardenia bloom season, the white orchid also blooms, the roadside often meets the granny carrying a basket of flowers in the hawking: "Gardenia, white orchid." Voice cadence, listening to it seems to smell the fragrance of white orchids. Gardenia needless to say, has always been my favorite fragrance, white flowers, the only regret is that it will attract a lot of small black insects. The flower shape of the white orchid is much smaller, exquisite, like a jade pendant, the color is white or some light yellow, the fragrance is also light and elegant, often can not help but buy a string, hang on the skirt or backpack, the fragrance can last all day. Grandmothers usually wear several flowers together with thin lead wire, and there will be a small ring at the top, which can be hung directly on the button.

Do not know where they come from the white orchid, Shanghai and Jiangsu and Zhejiang areas of the general white orchid is not outdoor winter, can only be potted, can not grow too big, winter needs to move indoors or closed balcony for the winter.

There will be more white orchids in the south. In Kunming and Guangzhou, white orchids can grow to more than ten meters. I almost didn't recognize them when I went to Guangzhou to see them tall and majestic, full of green leaves and fragrant flowers. There is also a kind of orange, locally known as yellow orchid, also known as yellow Burmese cinnamon, color and fragrance are somewhat close to sweet-scented osmanthus, but the flower patterns are very different.

White orchids bloom for a long time, almost from April to September, and the whole summer is elegant and fragrant, which is the advantage of the south.

White orchid (scientific name: MicheliaalbaDC.):

Trees of Magnoliaceae. Sex like light, afraid of high temperature, not cold-resistant, suitable for slightly acidic soil. Like warm and humid, not resistant to drought and waterlogging, sensitive to sulfur dioxide, chlorine and other toxic gases, poor resistance. [

Family potted white orchids should be cultivated in soils that are loose, permeable and rich in humus. Usually choose tile basin with good air permeability, purple sand basin (cylinder) or plastic basin with more bottom holes. It is better for the soil in the basin to have a certain amount of granular soil of different sizes to facilitate water seepage and air permeability.

Smile

The name of "smile" is really special. I can remember it once, but I know it at the beginning. I really don't understand such a simple flower, but it has such a good name. Guess the name of Michelia may have something to do with its flower shape, even to the most blooming point, the petals are not completely open, the flowers are in full bloom, reserved and reserved. Or maybe it's because of its fragrance, every time I walk past it, I can't help but be attracted by that fragrance, but the inconspicuous flowers and leaves contain such a sweet fragrance; about the smiling fragrance, some people say it's like banana, others say apple. I think it's more like cantaloupe ice cream, with delicate sweetness, in short, it's that kind of beautiful fruit sweetness, not thick or weak.

Scientific name: Michelia figo (Lour.) Spreng

Evergreen shrub, 2-3 m tall, grayish brown bark, leaves light green, leathery and oily, yellowish brown tomentose on petiole and pedicel.

Spring flowers bloom from April to June. The smiling flowers are not as big as other Magnoliaceae plants. When they are in full bloom, they are close to the yellowish green of the leaves. If you don't look carefully, you can hardly notice them. That's why you need to emit such a charming fragrance to attract the attention of insects.

When the bud expands and the outer bract will crack and fall off, the picked Michelia flower has the strongest smell.

When the flowers bloom in the later stage, the fragrance fades a lot.

Key points for pot conservation of Michelia mollissima

Fleshy root, keep the basin soil moist, avoid depression water, otherwise it is easy to rot the root. The growing period and flowering period require a large amount of water and need to be watered in time; the leaves are easy to fall off if they are too dry.

Like fertilizer, you can use rotten cake fertilizer, bone meal and so on to make the leaves bright green and increase the number of flowers.

Properly trim the long branches, sick and weak branches, etc.

The overwintering temperature is 0-5 degrees, which should be properly protected in winter. Large seedlings planted on the ground can withstand lower temperatures.

With a smile in the mountains:

White this kind of flowers and leaves at the same time, belongs to the mountain smile, the fragrance is very elegant.

Rescue for yellowing leaves and falling off

Because the roots of potted flowers can not stretch freely, the root development is restricted. if poor management, improper watering and fertilization, it is easier to produce leaf yellowing than open-field flowers, light appearance, heavy, the whole plant will die. For this reason, it is necessary to make a correct diagnosis in time and prescribe the right medicine to solve the problem. The causes, symptoms and remedial measures are briefly described as follows:

(1) too much water. The basin soil has been too wet for a long time, resulting in lack of oxygen and root rot. After being victimized, the young leaves first turned pale yellow, and then the old leaves gradually turned dark yellow. At this time, we should immediately control watering, stop fertilization, and often loosen the soil to make the soil well ventilated.

(2) drought and dehydration. Flowers missed or long-term watering half waist water (that is, wet down dry), will cause the leaf color dim, leaf wilting sagging. First, the lower leaves aged and turned yellow and scorched from the bottom up. At this time, appropriate amount of watering is needed to gradually recover and then transfer to normal water and fertilizer management.

(3) to lose weight for a long time. Without fertilization or changing soil for a long time, there is a lack of nutrition in the soil, resulting in thin branches and leaves and yellow leaves. It is necessary to pour the pot in time, replace it with new fertile and loose soil, and gradually apply flower fertilizer or thin fertilizer and water.

(4) excessive fertilization. When the concentration of fertilization is too high or the concentration of unmature fertilizer is too high, the concentration of nutrient solution in the soil is too high, which leads to the extravasation of flower cell fluid, the separation of plasma wall, and the scorching of the edge of old leaves until the whole plant dies. In this case, you should immediately stop fertilization, increase the amount of water, make the fertilizer flow out of the drainage hole, or immediately pour the basin, rinse the tuo with water and then plant it back into the basin, or remove part of the old soil and replace it with new culture soil.

(5) hot and high temperature. In summer, if J dangerously likes cool or shady flowers, such as orchids, cyclamen, Golden Bell, four Seasons Begonia, etc., put them in a high temperature place for direct sunlight, which can easily cause scorch on the tip or edge of young leaves. Need to be moved to a well-ventilated cool place for maintenance.

(6) excessive shading. Most flowers like sunlight, and if they are placed in places with too much shade or insufficient light for a long time, it will gradually lead to weak growth, thin and yellow leaves, no flowering or little flowering. Be careful to move the potted flowers to the sunny place.

(7) soil and water is alkaline. The soil and water in most northern areas contain more salt and alkali, and the flowers planted in acidic soil, such as Camellia, rhododendron, orchid, Michelia, mast, sweet-scented osmanthus, pearl orchid, night incense, magnolia, magnolia and so on. Due to the lack of soluble iron that can be absorbed by flowers in the soil, the leaves gradually become yellow and white, and even the whole plant dies. Acid soil is used when planting, and 0. 5% is often sprayed on the leaf surface. 2% ferrous sulfate solution, and regularly irrigate alum fertilizer water.

(8) whether it is airtight or not. Pot flowers apply too much nitrogen fertilizer, branches and leaves grow too luxuriantly, coupled with long-term unpruned, resulting in insufficient light of inner chamber branches and leaves, which is easy to appear leaf yellow shedding phenomenon. Pruning should be strengthened to make it ventilated and transparent, while reasonable watering and proper application of phosphorus and potash fertilizer should be applied.

(9) dry air. When the air of indoor flower cultivation is too dry, some flowers in a humid environment, such as orchid, tortoise back bamboo, magnolia, jasmine, Fusang, Michelia, etc., often appear leaf tip drying, or leaf edge scorching, or scorched spots on leaves, edge curling and so on. The incidence of the disease is more serious in the areas where the indoor coal stove is heated in winter. At this time, you should often use warm water close to room temperature to wash branches and leaves to increase air humidity. For some precious flowers, it is best to use a plastic film mask and put a small basin of water in the cover.

(10) pests and diseases. Leaf spot disease caused by fungi and other bacteria is easy to cause local necrosis of the leaves, the emergence of yellow spots or patches, serious withering and yellow shedding of the whole leaf. Yellow-green mottle appeared on the leaves after being infected by mosaic virus. Suffering from red spiders and other pests, the leaves will also become local yellow withered or even the whole leaf wilt and fall off. When diseases and insect pests are found, topiramate and dimethoate and other pesticides should be sprayed in time for control.

(11) strong sexual stimulation. The use of excessive concentration of pesticides in the prevention and control of diseases and insect pests, or polluted by toxic gases in the atmosphere, or when the temperature is high, sudden watering of cold water, etc., are easy to cause local scorch of the leaf tip or leaf surface, or even death of the whole plant. Therefore, we should pay attention to the rational use of pesticides, try to eliminate air pollution sources, and avoid watering flowers with cold water around noon in midsummer.
