What tips and tricks does the northern region have for planting and breeding southern flower varieties?

1. Match the basin soil. The suitability of potted soil is the basis of successful flower cultivation. Southern varieties generally like acidic and well-drained soil substrates, such as rhododendron, camellia, magnolia and so on. The common proportion of substrates is 4 parts of pine needle soil, 3 parts of peat and 2 parts of pastoral soil. this substrate not only has good water conservation, fertilizer conservation, drainage and air permeability, but also plays the role of alleviating fertilizer, which can basically meet the requirements of flower growth in the south.

two。 Scientific watering. Watering too often causes yellow leaves, few flowers and serious diseases and insect pests. Watering varies according to season, growth period, variety and basin soil. Such as more watering in growing period, less watering in flowering period, less watering in overcast and rainy days, more watering in dry season and so on. The water quality is required to be acid, which can be adjusted by adding ferrous sulfate.

3. adequate manuring. People often think that the more often the fertilizer is applied, the better, so tea root, beer, rice soup and bean dregs are all poured into flowerpots. This unripe fertilizer is not good for flowers at all and is easy to cause root burning. Fertilizer must be fully mature fertilizer liquid, diluted and then applied, but also a small amount of chemical fertilizer. The specific amount of fertilizer should be applied reasonably according to different plant varieties and different growth periods.

4. Adjust humidity and control temperature. Temperature and humidity are the environmental factors that restrict the normal growth of flowers and trees. Flowers in the south generally like shade and cool, like dampness and avoid dryness, and can be manually adjusted in the north. According to different varieties, sprayers are sprayed many times, and the humidification effect is good.

The culture method of the rich tree what if the leaves of the rich tree turn yellow?

It is believed that many people will put a wealth tree at home or in the office. The meaning of the wealth tree is very good at first. In addition, the tree shape of the wealth tree is very beautiful, and the green leaves are bright all the year round. It is a very good-looking foliage plant. But improper maintenance of rich trees can also lead to yellowing of leaves. The following is to introduce the breeding methods of the rich tree and the treatment of the yellowing leaves of the rich tree.

The culture method of rich tree

I. the choice of environment

The rich tree has strong adaptability, likes light and is resistant to shade, and grows well in full sunshine, half-day sunshine or shade. But if you grow up in the shadows for a long time, your chances will get worse. It is better to shade 50% at the beginning of summer so as not to scorch the leaf tip and edge caused by the hot sun.

In indoor culture and viewing, it is appropriate to place a certain amount of scattered light, not for more than 30 consecutive days. If there is a phenomenon of vitality turning bad and growing, you should gradually accept the sun and avoid being exposed to strong light quickly, so as not to adapt to death.

Second, the choice of basin soil

At present, most of the rich trees bought are the soil brought by businessmen. Flower lovers do not have to change the soil immediately after buying it, raise it first, and then consider changing the soil later. if you change the soil, the pot plants of the rich trees generally use loose vegetable garden soil or peat soil, rotten leaf soil, coarse sand, and add a small amount of compound fertilizer as base fertilizer and cultivation soil.

Third, watering rich trees

The root system of the rich tree is very underdeveloped, and many flower friends die because of rotten roots. Some flower friends will ask how often and how much a rich tree should be watered at a time. It should be made clear here that the situation is different in different places, pots and soil are also different, so there is no fixed watering standard.

So how to water it? Generally speaking, rich trees are watered once a month. In addition, they tell flower friends a little trick, that is, plants will not die soon after being short of water, and they will recover soon after watering, but if the stagnant water is waterlogged, it is basically impossible to save. Rich trees can spray more water and water less.

III. Fertilization of rich trees

Under normal circumstances, if the soil is fertile enough and does not need fertilization, if it has been raised for a long time, you can consider giving thin fertilizer, avoid thick fertilizer, fertilizing can use some common foliage fertilizer, remember to be thin fertilizer.

Note: generally speaking, rich trees are overcut, so every spring, flower friends can also give appropriate pruning, on the one hand, it can be beautiful, on the other hand, it can promote the growth of new branches.

Pay attention to the occurrence of diseases and insect pests

If it is found that the stem epidermis is blackened or black filamentous fibers are exposed, it is stem rot that causes the rich tree to rot. At the initial stage of the disease, 1000 times of water-soluble powder should be sprayed, once every 10 days, for 3 times in a row.

Anthracnose can be sprayed with 50% chlorothalonil wettable powder 800 times or 50% carbendazim 600 times, once every 10 days. For example, cabbage worm, inchworm and red spider can be sprayed regularly with 40% omethoate 800 times or 50% dichlorvos 1000 times, every 7 days for 3 times.

What if the leaves of the rich tree turn yellow?

1. Overwatering

The basin soil is too wet for a long time, which causes anoxia in the soil, causes some fibrous roots to rot, hinders normal respiration and absorption of water and nutrients, and causes leaves to turn yellow and fall off. After the injury, the young leaves turn pale yellow, and then the old leaves gradually turn yellow. watering should be controlled immediately, fertilization should be suspended, and the soil should be often loosened to make the soil well ventilated.

2. Drought dehydration

Flower cultivation leakage watering or long-term watering half waist water (that is, upper wet and lower dry) will affect nutrient absorption, and it is also easy to cause dull and dull leaves and drooping leaves. First, the lower old leaves aged, and gradually withered and yellowed off from the bottom up. At this time, a small amount of watering and spraying is needed to gradually recover and then turn to normal watering.

3. Lose weight for a long time

There is no application of ammonia fertilizer or no change of soil for a long time, and there is a lack of nitrogen and other nutrients in the soil, resulting in thin branches and leaves and thin and yellow leaves. It is necessary to pour the pot in time and gradually apply rarefied mature liquid fertilizer or compound flower fertilizer into new loose and fertile culture soil.

4. Excessive fertilization

If you fertilize too much, the new leaves will be thick and uneven, and the dry tips of the old leaves will fall off. You should immediately stop fertilization and increase the amount of water to make the fertilizer flow out from the drainage hole at the bottom of the basin, or immediately pour the pot, rinse the soil block with water and then plant it again into the basin.

5. Hot and high temperature

In summer, if you put cool flowers (such as cyclamen, Golden Bell upside down, four Seasons Begonia) in a high temperature place to let the strong light shine directly, it is very easy to cause the young leaf tip and leaf edge to scorch, or the leaf yellow to fall off. Move to a well-ventilated shady place in time.

6. Excessive shade

If the sun-loving flowers are placed in shady places or places with insufficient light for a long time, it will cause the branches and leaves to turn yellow.

7. Alkalinity of soil and water

There are more saline and alkali in soil and water in most areas of northern China, and flowers with acid-like soil are planted, such as rhododendron, camellia, Michelia, gardenia, orchid, magnolia, sweet-scented osmanthus and so on. Due to the lack of soluble iron and other elements that can be absorbed by the soil, the leaves will gradually turn yellow. Acid soil should be selected when planting, and alum fertilizer and water should be often watered during the growth period.

8. Whether it is airtight or not

If too much nitrogen fertilizer is applied, the branches and leaves will grow luxuriantly, coupled with the long-term unpruned, resulting in insufficient light in the inner chamber branches and leaves, which is easy to cause the leaves to yellowing and falling off. Reasonable fertilization should be applied and pruning should be strengthened to make it ventilated and transparent.

9. Air drying

When the indoor air is too dry, some flowers that like the humid environment, such as hanging orchids and orchids, often appear leaf tip dryness or leaf edge scorching and so on. Attention should be paid to water spraying, plastic film cover and other methods to increase air humidity.

10. Improper temperature

If the room temperature is too low in winter, the flowers are often vulnerable to cold damage, which leads to the yellowing of the leaves and death in severe cases. If the room temperature is too high, the transpiration of the plant is too high, and the root water and nutrients are in short supply, the leaves will turn yellow. Please pay attention to adjust the room temperature in time.

11. Soil partial acidity

It is easy to lose acid and magnesium in southern red loam. planting flowers and trees with alkali-tolerant or mute soil, such as oleander, yellow poplar, Yingchun, etc., are often prone to green and yellowing between the veins of old leaves. Can apply calcium magnesium phosphate fertilizer or spray magnesium sulfate solution.

12. Diseases and insect pests

Leaf spot disease caused by fungi and other bacteria is easy to cause local necrosis of the leaves, yellow spots or patches appear, the whole leaves wither and fall off seriously, yellow and green mottle appears on the leaves after being infected by mosaic virus, and damaged by shell insects, red spiders and so on, the leaves will also become local yellow, or even the whole leaves will wither and fall off. All should be sprayed in time.

13. Strong sexual stimulation

The use of excessive concentration of pesticides in the prevention and control of diseases and insect pests, or being polluted by toxic gases in the atmosphere, or suddenly watering cold water when the temperature is high, are easy to cause local yellowing and scorching of the leaf tip or leaf surface, or even the whole plant to die.

Therefore, we should pay attention to the rational use of pesticides and try to eliminate air pollution sources. Avoid watering flowers with cold water around noon in midsummer. Finally, it should be mentioned that the yellow leaves of potted flowers are sometimes caused by one reason, but they are often caused by a variety of factors, so a correct diagnosis should be made to prescribe the right medicine to the case.

The above is for you to introduce the breeding methods of the rich tree, and about the rich tree leaves yellow how to do some answers to this question, I hope you can understand, more household plant knowledge, please pay attention.
