Question 2: What fertilizer does potted gardenia need? Maintenance of potted gardenia: Gardenia is an acidic soil plant. Temperature: 16℃- 18℃. Therefore, it should be maintained in a well-ventilated and cool place in summer. Put it in a sunny place in winter. Moisture: I like moist air, and need to increase watering properly during the growing period. Fertilizer: Fertilizer-loving plants usually propagate by cutting.
Question 3: Fertilization method and time of gardenia. For gardenia with buds, it is best to apply compound fertilizer now. The content of phosphorus and potassium in this compound fertilizer is high, because phosphorus can promote the opening of flower buds and make flowers full and lasting. Potassium can make the stem strong and the bud big and strong. However, the amount of fertilizer should not be too much. 10- 15 compound fertilizer should be buried once every two weeks until mid-May. Mineral additives should be buried and applied according to the instructions for use. These flower shops sell them, so it is better to use them according to the brand description.
Question 4: What fertilizer should gardenia add? 1. Soil: Gardenia is an indicator plant of acidic soil, so the slightly acidic environment of the soil is the key to determine the growth of Gardenia. The culture soil is made of 70% slightly acidic sandy red soil and 30% rotten leaf material. The soil pH value should be controlled between 4.0 and 6.5.
2. Temperature: The optimum growth temperature of Gardenia is 65438 06℃-65438 08℃. Low temperature and direct sunlight are extremely unfavorable to its growth, so gardenia should be maintained in a well-ventilated, high-soaked and light-filled sparse forest or shade shed in summer. In winter, let it sleep in an environment with plenty of sunshine and a temperature not lower than 0℃. If the temperature is too high, it will affect the flowering next year.
Third, moisture: Gardenia likes humid air, and it should be properly watered during the growth period. Usually when the soil is white, you can water it once and pour it thoroughly. It is hot and dry in summer. Spray leaves 2 -3 times a day to increase air humidity and help plants cool down. However, after the flowers are in bud, it is not advisable to water them too much to avoid falling buds. It is better to water dry in winter to prevent the roots from rotting.
Fertilizer: Gardenia is a fertilizer-loving plant. In order to meet the demand for fertilizer in its growing period and maintain the slightly acidic environment of the soil, ferrous sulfate can be mixed into the fertilizer solution in advance for fermentation. After entering the growing season in April, topdressing can be done once every half month (it is best to add more water when applying fertilizer to prevent burning flowers). This can not only meet the demand of gardenia for fertilizer, but also keep the soil environment in a relatively balanced slightly acidic environment, prevent the occurrence of chlorosis, and avoid the damage to gardenia caused by sudden supplementation of ferrous sulfate and local peracid.
5. Propagation: Although there are many propagation methods of gardenia, the floating water insertion method is the simplest and fastest. First, find a foam board to punch holes, cut off the semi-mature branches of gardenia and insert them into the small holes of the foam board, then put the foam board into a bucket filled with water, and put the bucket in an environment that can not only block the floating board cuttings, but also let the sun shine on the bucket, and control the water temperature at 65438+. The survival rate of cutting Gardenia jasminoides Ellis by this method is 65438 000%.
The newly bought gardenias have all dropped their buds. Why?
Improper water and fertilizer. 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, nutrients are mostly used for physiological growth, branches and leaves grow excessively, physiological growth is inhibited, reproductive organs lack nutrients, and shadow flower buds are formed, resulting in no flowers or few flowers, even if buds can be conceived, 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 should be sprayed with 0.2%-0.5% ferrous sulfate aqueous solution frequently during maintenance to prevent iron deficiency from yellowing.
5. Lack of pruning. 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. ...& gt& gt
Question 5: What flower fertilizer does gardenia use? Only by mastering its physiological characteristics can leaves, flowers and fruits be beautiful and their ornamental value be improved.
1. Acid-loving soil: Soil, water and fertilizer contain alkali, which prevents plants from absorbing iron, thus affecting the formation of chlorophyll, making branches wither, leaves scorch and even die. Rich, loose and well-drained acid soil should be selected. If pine sawdust is fully mixed into the soil, the use effect is also very good.
2. Like cool: avoid exposure to the hot sun, but some people often mistakenly think that gardenia needs full shade, leading to cultivation mistakes. In fact, while paying attention to cultivating its cool environment, it is necessary to keep 60% light all day to meet its growth needs.
3. Humidity: If the air humidity is lower than 70%, it will directly affect the differentiation and growth of flower buds, but if it is too humid, it will lead to root rot, branches wither and leaves fall off. In addition to normal watering, the leaves and nearby ground should be sprayed with clear water frequently to appropriately increase the air humidity.
4. Fertilizer-loving: Fertilizers such as cooked bean cake, sesame sauce residue and peanut bran should be applied, which can be acidic after fermentation and decomposition, but they must be applied thinly, avoid thick fertilizer and raw fertilizer, and do not apply fertilizer during hibernation. It is forbidden to use human excrement if it has been planted for less than three years. Too much nitrogen fertilizer will cause thick branches, large leaves and dark green, but it will not bloom. When phosphorus and potassium fertilizer are lacking, there will be no flowering or bud withering and falling off.
5. Thermophilic: The growing period is 18℃ to 22℃, and the wintering period is 5℃ to 10℃, and it is easy to be frozen below-10℃.
6. Timely pruning: Gardenia has strong germination, easy overlapping of branches, dense ventilation and scattered nutrition. In orthomorphism, three main branches should be selected according to the tree shape, and other branches sprouting from roots should be cut off at any time. After the flowers wither, the branches should be shortened in time to promote the germination of the new branches cut. After the new branches grow for three days, the core should be removed to avoid blind growth.
7. Prevent yellowing disease. There are four reasons: ① Iron deficiency. Excessive calcium, alkali, phosphorus and manganese in the soil will affect the absorption of iron by plants, affect the formation of chlorophyll, make the veins of young leaves turn green and spread the whole leaves. 1/500 ferrous sulfate water or 0.2% black alum water, once every 10 day. ② magnesium deficiency. Too much acid red loam and potassium and ammonium are prone to magnesium deficiency, which makes the veins of the lower old leaves turn green and yellow. It can be sprayed with 1% to 2% magnesium sulfate solution, but excessive magnesium application will cause calcium deficiency and hinder the development of xylem of roots and stems. ③ The basin soil is too wet or too dry. 4 exposure in summer.
Gardenia likes warm and humid semi-shady environment, slightly resistant to shade and afraid of strong light. In summer, it should be kept in a cool shed or under the shade of flowers and other places where light is scattered. Therefore, to cultivate in acidic soil rich in humus, generally 3 parts humus soil, 2 parts sandy soil and 5 parts garden soil can be mixed. Rainwater or fermented rice washing water should be used for irrigation; If it is tap water, it should be dried for 2 to 3 days before use. Pouring 0.2% ferrous sulfate (black alum) water or applying alum fertilizer water once every 7 days to 10 in the growth period (both can be done alternately) can not only prevent soil alkalization, but also supplement iron in the soil, which can not only prevent the leaves from yellowing, but also make the leaves oily green and bright, and the flowers are full. Gardenia likes to be wet. Water the plants and the surrounding ground frequently in spring, summer and early autumn to keep the soil and air moist and make the plants grow vigorously. But after the heavy rain, the accumulated water in the basin should be poured out in time to prevent the roots from rotting. In winter, put it in the indoor sunshine, stop fertilization and keep the temperature above 5℃, but it can also withstand the short-term low temperature of 0℃. Don't water too much, and the branches and leaves can often be washed with water close to room temperature. Keep the leaves clean and prevent dust from polluting the leaves, especially in rooms with heating in the north. Turn the pot every 1 to 2 years in spring. Prune the plant once a year in spring, and cut off the long branches, weak branches and other messy branches that affect the plant shape, so as to keep the plant shape beautiful, promote the development of new branches and make it bloom more.
Question 6: What is the best fertilizer for gardenia? Maintenance of potted gardenia: Soil: Gardenia is an acidic soil plant. Temperature: 16℃- 18℃. Therefore, it should be maintained in a well-ventilated and cool place in summer. Put it in a sunny place in winter. Moisture: I like moist air, and need to increase watering properly during the growing period. Fertilizer: Fertilizer-loving plants usually propagate by cutting.
Question 7: What fertilizer does gardenia use? Just use ordinary granular fertilizer, once every half month.
Question 8: What fertilizer is the best for gardenia? Gardenia is afraid of hypertrophy, so it should be applied twice with cake fertilizer containing more phosphorus and potassium fertilizer before budding, and stopped after budding. During the growth period, it can be used with decomposed cake fertilizer or manure, and a small amount of ferrous sulfate is also called black alum as topdressing, which is applied once a month.
Question 9: When does gardenia need fertilization? When does gardenia need fertilization?
Gardenia needs reasonable fertilizer supplement during its growth period. Apply decomposed human excrement or cake fertilizer once every 10 day, stop watering 1 day before fertilization, and water 1 time at the same time on the day of fertilization. Fertilization was stopped in mid-September. For adult plants, sesame paste residue should be applied again in mid-June and mid-August, with 0.5- 1 2 each time, and thoroughly mixed with topsoil after crushing.
Gardenia flower fertilization method
1. Gardenia should be fertilized with fertilizers such as fermented bean cake, sesame sauce residue, peanut bran, etc., which can be acidic after fermentation and decomposition, but more thin fertilizers must be applied to avoid thick fertilizers and raw fertilizers, and no chemical fertilizers should be applied during hibernation.
2. Stop watering gardenia before fertilization, and water it thoroughly when fertilizing.
3. During the growth period of Gardenia, apply proper fertilizer when flowering, and add fertilizer again after flowering.
4. If gardenia has been planted for less than three years, it is forbidden to smear human feces. Too much nitrogen fertilizer will cause thick branches, large leaves and dark green, but it will not bloom. When phosphorus and potassium fertilizer are lacking, there will be no flowering or bud withering and falling off.
Matters needing attention in fertilization of Gardenia jasminoides Ellis
Gardenia likes fertilizer, but you can't add too much fertilizer at a time. Be sure to apply more fertilizer thinly, and don't be greedy and save trouble, otherwise it will cause thick branches, large leaves and thick green, and lose its own appreciation effect.
The reason why gardenia doesn't bloom.
1, improper water and fertilizer, once excessive water and fertilizer, will cause plants to grow white, reproductive growth without enough nutrients will affect the formation of flower buds, resulting in no flowering or less flowers, some open, or even fall off immediately. Special attention should be paid to the coordination of phosphorus and potassium fertilizers during flower bud differentiation, such as 0.2% potassium dihydrogen phosphate solution, which is beneficial to the formation of flower buds and the pregnancy of buds; Excessive fertilization and frequent watering during bud pregnancy can also lead to falling flowers and seedlings.
2, the light is not suitable, scorpion flowers like shade, so pay special attention to the light that is too strong in summer and too weak in winter. Too strong and too weak light will affect the flowering of gardenia.
3. The soil has high alkali content, and gardenia likes acidic soil. The high saline-alkali soil where gardenia is planted will lead to the yellowing of plants and eventually affect flowering.
4. Without pruning, the branches of Gardenia are messy, a large number of miscellaneous branches consume a lot of nutrients, and the branches are too dense, which affects photosynthesis, all of which are important reasons for not flowering.
5, serious pests and diseases, I believe everyone can understand that serious pests and diseases will inevitably lead to falling flowers.
How to fertilize gardenia and what fertilizer to use are introduced here, hoping to help everyone. Welcome everyone to continue to pay attention to this site and learn more about gardenia conservation knowledge.
