1 moisture, gardenia likes warm and humid, but too much moisture can easily lead to poor root respiration and serious root death, which affects plant water absorption. Of course, it is easy to drop flowers without water; 2 illumination, if the illumination is insufficient for a long time, it will turn yellow, and the sun will turn yellow; 3. The humidity is not suitable, the first edition has little influence, and the environmental humidity is not easy to change. Southwest China is the most suitable environmental humidity; 4. If the temperature is too high, the flowers will fall off, and the optimum temperature is 22-26; A large amount of phosphorus and potassium fertilizer is needed at flowering stage. If the soil is not enough, potassium will transfer from the old leaves to the flowers, so the old leaves will turn yellow first. If it is not enough, the flowers will fall off. Suggest buying potash fertilizer in specialty store. If it is not easy to buy, you can burn the hay leaves into ashes and apply fertilizer as the raw material of potash fertilizer.
Summary of nursing methods: Gardenia likes warm, humid, well-lit and well-ventilated environment, but does not like strong light irradiation. Suitable for living in a slightly cloudy place, resistant to semi-shade, afraid of stagnant water, not cold. It can only be used as greenhouse potted flowers in northeast, north and northwest China. It should be planted in loose and fertile light sticky acid soil with good drainage, and it is a typical acid flower.
Question 2: My gardenia always drops buds and won't bloom. Why don't you see if there is rot where the bud falls? If there is mildew, you can spray diluted carbendazim. If not, even if there is too much water, too little light, more sunlight and photosynthesis, it is easy to bloom. Gardenia likes acidic soil, and ferrous sulfate can be applied once every half month.
Question 3: What is the reason why gardenia flower buds fall off? Gardenia: Rubiaceae, Gardenia.
Habit: like warm and humid climate, not cold-resistant. Hi-light is also slightly resistant to semi-shade, and leaves are well shaded (referring to outdoor lighting conditions). I like well-drained, soft and fertile slightly acidic soil.
Gardenia likes fertilizer and applies thin fertilizer once or twice a month. Prune once in May and July, and cut off the top branches to form a complete crown. Picking the residual flowers in time after flowering is conducive to vigorous flowering and prolonging the flowering period.
Gardenia is a common biological disease "bacterial wilt" in the north, which usually occurs when cultivated in alkaline soil. At the beginning of the disease, the leaves turn yellow; What's more, the branches and leaves are burnt and the flowers are sparse until the whole plant dies. One thousandth to two thousandths of ferrous sulfate solution can be used for irrigation once a month to prevent it.
Your gardenia:
①: It is certain that the shading time is too long. Try to put it in a bright place indoors. Usually, it should be moved to a cool, ventilated and bright place outdoors for three to five days (when this pot of gardenia is moved outdoors, it must be careful not to be exposed to direct sunlight, otherwise the leaves will be burnt, and it should be placed in a bright and cool place), so that it can be used for photosynthesis to supplement nutrition and continue to be placed indoors.
②: As for watering several times a day or once every few days, most of them can't grow flowers. Water should be based on the habits of flowers, different seasons, soil moisture and other factors. Now that the weather is hot, the soil of gardenia can be kept a little moist. Water it when the soil is dry in Yichun and autumn, and dry it in winter. Spraying it on the leaves during air drying in the north is beneficial to increase the relative humidity of the air. There is heating in Tianjin in winter, so water gardenias and put them in a place not lower than MINUS five degrees for the winter. Too hot is not conducive to dormancy and will affect the growth in the coming year.
③ Pots for potted plants are best earthen pots, which are difficult to buy now; Then there is the purple (white) sand basin, which is beautiful in ventilation (it will become more and more difficult to buy); The worst are porcelain pots (such as glazed pots) and plastic pots, which are completely airtight; Porcelain pots are generally used as ornamental pots outside the planting pots. Therefore, peat soil, vermiculite, perlite and coconut chaff are now used to improve the soil permeability of porcelain pots and plastic pots.
. Otherwise, the flowers will not grow well.
It is recommended that you do not use porcelain or plastic pots, or improve the air permeability of the soil.
Few insects can be caught in time, and using pesticides is not good for your health.
You have kept the flowers indoors for too long. Now you must keep them outdoors in a cool and ventilated place for at least half a month. Spray as many plants as possible, but no matter how many times you spray, you can't save the flowers. What is important now is to save your life. Don't fertilize in the near future, wait for it to recover slowly. It is not too late to apply thin nitrogen fertilizer until new buds and leaves sprout.
I hope I can help you.
Question 4: Why do the flower buds of Gardenia fall off so easily? It should be malnutrition. Pay attention. There are two gardenia trees in my family, which have been raised for more than ten years and have never dropped their buds. A vine was planted last year, and its leaves turned yellow, not sick, but obviously malnourished. See if there is a similar reason for yours. There are bugs in the soil. Check whether the soil has hardened. If the board is hardened, loosen the soil and simply change the soil.
Question 5: Why does the flower bone of gardenia grow old? Common reasons for gardenia falling buds are as follows:
1, lack of fertilizer, gardenia lack of fertilizer, the tree grows weakly, even if it bears flower buds, it is easy to dry up and fall off. Therefore, gardenia should pay attention to applying some nitrogen fertilizer and iron fertilizer when maintaining at ordinary times, and increase the supply of phosphorus and potassium fertilizer after budding. Before the leaves are renovated every spring, the supply of base fertilizer can be increased or buried in the basin soil.
2, lack of water, gardenia likes big water, Huayun: jasmine that never dies in drought, gardenia that never dies in waterlogging, as long as there is no water in the basin, try to increase the water supply.
3. Large amount of water, high soil moisture and poor root respiration will lead to poor plant growth and bud loss.
4. The air humidity is low. Gardenia is a southern flower and likes warm and humid climate. If the air humidity is too low, it will cause bud drop. Therefore, in the process of maintaining gardenia, gardenia should grow in a high humidity environment, and can be sprayed on the leaves with a watering can.
5, pests and diseases, carefully check the plants for fungal hazards such as white powder and black spots, and pay attention to the hazards such as red spiders and scale insects. If there is, treat it symptomatically, otherwise gardenia will fall off easily after budding, with little or no flowers.
6, harmful gases, sulfur dioxide, hydrogen sulfide, etc. It has an effect on the growth of gardenia. For example, the air pollution is heavy, and the content of such gases is high, which will cause poor growth of gardenia and insufficient nutrient reserves, and more buds will fall off after budding in the next year.
Just to be clear, gardenias like scattering light, so don't expose them to the hot sun. If exposed to the hot sun, the leaves will dry up, yellow and fall off, and the whole plant will die.
Question 6: Why do gardenia flower buds rot? Generally, the flowers bought back should adapt to the environment. Sudden changes in the family are likely to cause too much lightning or too little fertilizer. It is possible to burn more flowers. What is the specific situation of your home? Study for yourself.
Question 7: What should I do if the gardenia falls off? Don't have too much water. Too much water should cause flowers to wither. Only when the topsoil is white or cracked can it be watered. If it is wet, don't water it. Lack of nutrition can also easily lead to the phenomenon of dead flowers falling. Bury 30 high-phosphorus and high-potassium compound fertilizers in pots, because phosphorus can promote flowering and make flowers bloom for a long time, and potassium can make branches strong. Lack of light can also easily lead to the phenomenon of falling flowers, so move out for an hour in the sun in the morning or evening. Enhance photosynthesis, so that plants can get more self-nutrition, so that it is not easy to cause flowering.
Question 8: Why do gardenia buds fall off? If there is insufficient light, both temperature and humidity will occur. Gardenia usually blooms in summer, which requires high temperature, high humidity and strong light.
Question 9: Gardenia flowers fall off their buds. Why should gardenia be malnourished? Attention, there are insects in the soil. Check whether the soil has hardened. If it hardens, loosen the soil. Simple soil replacement is beneficial to the growth of its root system and better transport nutrition. Try this.
Gardenia jasminoides (scientific name: Gardenia ja *** inoides), also known as gardenia, gardenia, Rubiaceae. Mainly distributed in Sichuan, Jiangsu, Zhejiang, Anhui, Jiangxi, Guangdong, Yunnan, Fujian, Taiwan Province and other places. Like warm and humid, like sunshine, cold-resistant, semi-cloudy, afraid of stagnant water, requiring loose, fertile and acidic sandy loam, native to China. Belonging to Rubiaceae, it is an evergreen shrub with lush foliage, evergreen leaves and fragrant flowers. It is an important garden ornamental plant. Besides ornamental, its flowers, fruits, leaves and roots can all be used as medicine, which has the effects of purging fire, removing annoyance, clearing away heat and diuresis, cooling blood and detoxifying. Leaves opposite or 3 leaves, leaves obovate, leathery, green and shiny. Berries are oval, yellow or orange. I like warm, humid and sunny environment, which is relatively cold-resistant. Gardenia is semi-cloudy, afraid of stagnant water, and requires loose, fertile and acidic sandy loam. I like a well-lit and well-ventilated environment, but I don't want to be exposed to strong light. It should be planted in loose and fertile acid soil with good drainage. It can be propagated by cutting, layering, dividing plants or sowing. Flowers can be used as the spice of tea, and fruits can diminish inflammation and dispel heat. This is an excellent fragrant flower. Gardenia usually refers to the variety of gardenia with double petals for ornamental purposes. Leather is rectangular and shiny. Axillary flowers with short peduncle and fleshy. The fruit is ovoid to oblong, with 5-9 wing-like straight edges, and the cell1; There are many seeds embedded in the fleshy placenta. From May to July in bloom, flowers, leaves and fruits are beautiful, and the flowers are overflowing. Roots, leaves and fruits can be used as medicine, and have the effects of purging fire and relieving annoyance, clearing away heat and diuresis, cooling blood and detoxifying. Its fruit can be used as a pigment for painting.
Question 10: improper fertilization and watering of gardenia flower buds, too much nitrogen fertilizer, insufficient phosphorus fertilizer and too much watering are the two main reasons for flower buds. The following are various reasons for gardenia flower buds for your reference: improper fertilization and watering. Gardenia likes fertilizer, so it balances and fertilizes organic fertilizer, cooked bean cake, sesame sauce residue, peanut bran and so on. After fermentation and decomposition, it can be acid fertilizer, but only thin fertilizer can be applied frequently to avoid thick fertilizer and raw fertilizer. Too much fat can easily lead to damage to the root name and even rot. In the growing period, if there is excessive water and fertilizer, especially nitrogen fertilizer, the nutrients are mostly used for physiological growth, the branches and leaves grow excessively, the physiological growth is inhibited, and the reproductive organs lack nutrients, which affects the formation of flower buds, resulting in no flowers or less flowers, even if they can conceive buds, they are easy to fall off. Therefore, in the stage of flower bud differentiation, it is necessary to pay attention to increasing the application of flower fertilizer containing more phosphorus fertilizer or watering or spraying leaves with 0.2% potassium dihydrogen phosphate solution, which is beneficial to bud pregnancy and ducray. Secondly, excessive fertilization and uneven watering during bud pregnancy are also easy to cause falling flowers and buds. Flowers with flowers and bones have the most vigorous physiological activities. They should not only meet the needs of physiological growth, but also meet the needs of reproductive growth, which needs to transport a lot of nutrients to leaves and flowers through roots. At this time, if the conservation environment changes suddenly, or the flowerpot breaks down, the physiological balance will be broken, and the leaves and buds can't adapt to the new environment quickly or get proper nutrition, so the leaves will fall off, the buds will fall off, and even die. Three minor discomforts. Gardenia likes humid and semi-cloudy environment during its growing period, and it should be fully illuminated indoors in winter. If the growing environment is not satisfied, and the sun is not seen for a long time, and photosynthesis cannot be carried out, the leaves will turn yellow, leading to falling flowers and buds. Gardenia also needs iron to moisten, and iron deficiency will lead to yellowing. It will also affect its growth and flowering. This is because the soil is fully absorbed in the slightly acidic strip, so it is most suitable for the growth and development of flowers. Alkaline soil not only affects flowering. In severe cases, it will lead to plant death. Therefore, gardenia must use acidic soil with good ventilation and air permeability, and it should be sprayed with 0.2%-0.5% ferrous sulfate aqueous solution frequently during maintenance to prevent iron deficiency yellowing and missing branches. Gardenia, if it is not trimmed and reshaped for a long time, the branches will be messy, which will not only affect the appearance, but also consume a lot of nutrients on useless branches, which will not only affect the formation of flower buds, but also cause the buds to fall off. 6. Pests. Gardenia should grow in a well-ventilated semi-cloudy and semi-humid environment, otherwise it is vulnerable to pests and diseases. For example, in the long development period, suffering from plant diseases and insect pests will destroy the growth potential of plants, affect the accumulation of nutrients, and also lead to falling flowers and buds.
