Solution: put it in a bright and ventilated place on the balcony and trim the bad leaves. Water is often sprayed on the leaves to increase humidity, and it is better to add some potassium dihydrogen phosphate, so that the leaves are greener and brighter.
Maintenance and management of potted citrus;
? Lighting, potted oranges are placed in a bright and ventilated place on the balcony. It is best to have a higher light intensity, which is easy to blossom and bear fruit. It is easy to grow in the dark, with few flowers and few fruits.
? Moisture, oranges are more drought-tolerant, and can be watered when dry. If you don't dry the soil and water it, you are afraid of waterlogging. It is best to see the dry humidity of the basin soil before watering, and water it in time when it is dry.
? Nutrients, orange trees like to fertilize, from March to September, it is best to fertilize water once every half month in the growing season, so that plants grow better and more vigorously. Spraying potassium dihydrogen phosphate to leaves often can promote the flowering and fruiting of plants.
? Pests and diseases, potted oranges are placed indoors, which is poor in ventilation and easy to breed scale insects. It is best to spray pesticides for about a month during the growth period to prevent pests.
How to cultivate potted citrus reticulata how to cultivate potted citrus reticulata potted citrus reticulata
1. Pot changing: according to the size of citrus reticulata, choose a round flowerpot with appropriate size, and the mouth of the flowerpot should be larger, which is convenient for fertilizing and loosening citrus reticulata in the future. The flowerpot should have good air permeability and water permeability to ensure the oxygen demand for the growth of citrus roots.
2. Soil: When replacing the flowerpot, the soil should be replaced at the same time. Pour out the original basin soil, add some sandy loam or sandy soil rich in humus, and some organic fertilizer. For the old pot soil, stir the soil fully and evenly, then pour some water to moisten it, and then put the pot soil back into the flowerpot.
3, lighting: orange tree is a kind of fruit tree that likes sunshine. When planting potted citrus reticulata at home, it is more appropriate to put potted citrus reticulata in a sunny and well-ventilated environment, usually on the balcony. In sunny days, citrus reticulata can often be moved to the sun to bask in the sun, which can promote the growth and flowering of citrus reticulata.
4. Pruning: If you want to make the potted orange tree look good, you need to prune the orange tree from time to time and prune some messy branches of the orange tree to maintain its good shape and improve its aesthetics.
5. Water: Pay attention to the amount of water when watering potted citrus reticulata. Generally speaking, orange trees should be watered once a day in summer. If the soil is dry, water more 1 times. Water is only watered once a day in spring and autumn and once every 3-4 days in winter. Don't water too much each time, just make sure the soil is wet.
6, temperature: orange trees are not cold-tolerant fruit trees. In the cold winter season, attention should be paid to keeping potted plants in citrus reticulata. Generally, it is best to move potted orange trees indoors. But in the warmer winter in the south, you don't have to move indoors.
7. Water conservation: "Water conservation" before flowering In order to prevent excessive growth of summer shoots, at the same time, trees should accumulate nutrients and promote the formation of buds, and potted citrus should be "water conservation" before summer. The specific method is to gradually reduce the water supply to potted oranges more than ten days before the hot summer; In the first 5 days, the water was stopped, the basin soil was exposed to the sun, a lot of water evaporated, and the basin soil was dry; Due to the lack of water in roots, branches and leaves lose water, and leaves wither and curl. In order to prevent dehydration of leaves, water can be sprayed on the leaves in the morning and evening, and a small amount of water can be sprayed on the pot soil at the same time, so that the axillary buds of oranges expand day by day and the color of buds turns from green to white when they are dry and immortal. When most axillary buds turn from green to white,' withholding water' promotes flower success. At this time, it is necessary to restore the water supply of potted oranges in time.
8. Protect the flowers and fruits: After the oranges bloom, in addition to applying thin fertilizer once a week, the flowers and fruits must be thinned. Sparse some buds before flowering; After the flowers wither and set fruit, some young fruits in inappropriate positions should be thinned out to reduce the consumption of nutrients, so that the limited nutrients can be concentrated on the preserved flowers and fruits, and the fruits can grow bigger and better. In the process of fruit growth, if the fertilizer and water are sufficient and the plants are nutritious, some branches will sprout new buds, and the growth of new buds will inevitably divert some nutrients, which will affect the growth of fruits. In order to protect the fruit, the new buds should be smoothed in time. When the fruit turns yellow, stop fertilizing, reduce watering and keep the soil moist and slightly dry. If we continue to give too much fertilizer and water, the fruit will ripen and fall early, shortening the viewing time.
9, reasonable fertilization: oranges like fertilization, usually should be relatively thin fertilizer. Apply decomposed liquid fertilizer once before the plants germinate, and then apply liquid fertilizer mainly containing nitrogen every 7 ~ 10 days to promote more branches and leaves and more spring shoots. Fertilize in time after each coring to promote the early maturity of branches. During the growth of citrus, you can sprinkle some cake fertilizer on the basin surface, so that some fertilizer can penetrate into the soil every time you water it, and enhance the fertility. After autumn, fertilization will be reduced, plant nutrition will be avoided, autumn shoots will be promoted, and fruits will compete for nutrients, leading to fruit drop.
What should I do if the leaves of potted orange are curly and dry? Oranges like acidic soil, and the lack of acidity in the soil will cause the yellow leaves of orange trees to fall off. You can buy a pack of ferrous sulfate at the flower market, melt it in a larger beverage bottle, soak it until it turns rusty, and dehydrate it for later use. Wu listens to the owner of the flower shop, and it doesn't matter whether he picks it up or not. Don't make me sad. In today's society, no one believes in the truth, so many people like to be fooled, and good people are hard to do.
All the leaves of my potted orange tree have fallen off. How to prune branches and leaves and control watering is better. It doesn't matter if the soil is dry without watering. Small evaporation, high humidity, easy to rot, and germinate next spring.
It may be one of the following reasons: 1, root injury, resulting in insufficient nutrition supply. 2. When transplanting, the humidity of the soil can not be guaranteed, which may be caused by being too dry or too wet. 3. When transplanting, the soil ball is not big enough, or it is too loose. There may be other reasons, but I don't know how you transplanted it. Think for yourself.
What should I do if the leaves of potted oranges turn yellow? 1. Kumquat likes wet, but is afraid of waterlogging. Kumquat is watered every three or four days from the time it leaves the house in spring to the time it blooms in early summer to keep the soil moist. Summer after the young fruit period is hot, so you can water it once a day. Lack of water will not only cause the leaves to wither, but also make the fruit fall off easily.
2. Kumquat likes light, but is afraid of strong light. Too strong light burns leaves easily. In summer, it needs to be kept under a shade shed, especially at noon, so that it can be exposed to sunlight before 9: 00 am and after 5: 00 pm. In early autumn, it should be kept in a sunny place indoors in late autumn and winter, and fully exposed to sunlight. The reason why leaves turn yellow:
1, the environmental change of oranges leads to serious water absorption of leaves.
Oranges are new before you buy them. Oranges are not adapted to the soil, which temporarily affects nutrient absorption.
3. The newly bought oranges, watering and placing environment are not suitable for the growth of oranges.
4. Too much watering will damage the roots.
5. Too much or too little fertilization will cause the leaves to turn yellow.
Potted orange leaves turn yellow, so avoid sun exposure, ventilate the soil and don't water more. Only when the soil is dry can it be poured thoroughly at one time. At the same time, organic fertilizer and magnesium should be supplemented.
How is the yellowing of potted orange leaves? Now the temperature is a little low, plants are not suitable for growth, and it is normal for old leaves to turn yellow. It is best to put it in a bright and ventilated place on the balcony. When it is dry, water it in time and just trim the bad leaves.
How to raise potted citrus reticulata? Potted rutaceae plants are usually changed once every three years. Knock the plants out of the pot before flowering, and cut off the roots that are too dense with scissors. The size of the new flowerpot depends on the growth of the plant. If the pot grows well, choose a big pot, and the bottom of the pot is made of broken pieces. After a layer of soil, put a few horseshoes in it, and then put another layer of soil on it. The culture soil should be neutral in soil, rich in humus, loose and fertile, well drained, compacted while filling, and finally watered once and placed in a cool place.
When changing pots, it is best to apply decomposed organic fertilizer to them. Apply dilute liquid fertilizer to it two or three times in summer. Apply thin fertilizer every half month after flowers wither, apply some compound fertilizer after fruits are formed, and add phosphorus and boron fertilizer to promote fruit development and enrichment. Fertilize it, preferably with liquid fertilizer, once every seven days after leaving the house in spring and before budding (from mid-April to early June), with the flowering period suspended, and once every 10 day after fruit setting to the fruit growth period (from early July to the end of September). Using liquid water mixed with sesame sauce residue and horseshoe slices with water to make kumquat sour has the best effect, which can make the plants grow vigorously, and the fruits are large and colorful.
