The leaves of orchids will naturally turn yellow. Is it different grass?

Hello, I'm glad to answer your question. It is true that some blue flowers have turned yellow and their characters have changed. That's what people call variation, but it's generally not obvious.

To cultivate orchids, we should avoid the following misunderstandings.

1: More water.

Some flower growers think that flowers drink water every day just like people, so frequent watering will make the flowers bloom beautifully. In fact, the more water, the better. You should water it properly according to different flowers.

Generally, water can be poured once a day in the morning, and appropriate supplementary watering can be carried out at night according to the dryness of the basin soil, and no watering can be carried out during the day. Water thoroughly when watering, subject to the water flowing from the bottom of the basin. Of course, some flowers with fleshy roots, such as Clivia, need to control the amount of watering, otherwise too much water will easily rot the roots. This kind of flower only needs to spray some water on the leaves at dry noon. And some drought-tolerant flowers such as cactus, cactus, etc. should also be watered less, otherwise the roots will rot easily.

Myth 2: Put it indoors.

Some flower farmers see the strong sunshine in summer or the cold weather in winter, fearing that the flowers will get sunburned or freeze to death, or are too busy to take care of them, and simply move them indoors. However, the result of this is that the flowers lack sunshine for a long time, leading to poor growth. In fact, some flowers like sunshine, for example, positive flowers are not afraid of strong sunlight, and only need proper shading at noon in summer.

Of course, neutral flowers should be properly shaded. If it is a balcony potted flower, it can be moved indoors from 10 to 3 pm every morning. If it is a shade-loving flower, don't touch strong light. However, it is always good for flowers to bask in the sun, just like taking a baby out to bask in the sun, so that flowers will grow strong.

Myth 3: Fertilize more.

Some flower farmers mistakenly believe that the more fertilizers are applied, the better the flowers will grow, so they buy various fertilizers and often fertilize the flowers. As a result, the flowers are not flourishing, but growing worse and worse. In fact, this is like giving people too much nutrition, but getting sick because they can't digest it for a while. Flowers should absorb nutrients bit by bit, not a lot at once, or they will hurt their roots.

Fertilization should be based on the climate, and the temperature in spring and autumn is suitable, which is the peak season for flower growth. Fertilization can be increased at this time. The temperature is high in summer and too low in winter. During these two periods, some flowers go into dormancy and absorb less fertilizer. Therefore, flower growers should apply as little fertilizer as possible according to different flower properties. Of course, flowers that bloom in summer are more resistant to high temperature and can be fertilized more, such as crape myrtle, jasmine and Lihua. And make it flourish in flowering period. Some ornamental flowers, such as five-color pepper, can bear more fruits after flowering by topdressing with phosphate fertilizer. Tropical foliage plants, such as bamboo, should be topdressing with nitrogen fertilizer to make their leaves greener. Avoid high concentration and apply more fertilizer.

Here is a summary of fertilization tips: apply more yellow and thin, apply more before germination, apply more during pregnancy, and apply more after flowering; Apply less fertilizer, no germination, less flowering, and less application in rainy season; No new planting, no summer, no growth, no dormancy.

Myth 4: The more flowers you plant, the better.

Some flower farmers put a lot of plants in the room regardless of the size and function of the room, which makes the space appear messy, crowded and narrow. In this way, planting flowers will not only lead to the failure of spatial function, but also make the room lack harmony and aesthetic feeling, which is also unfavorable to the growth of plants. In fact, a living room of about 15 square meters is only suitable for putting 2 pots of medium and large plants, while 3~4 pots of small plants are very good.

Myth 5: Growing flowers is greedy.

Some flower farmers like to buy all kinds of flowers back. The more the better, the more varieties the better. In fact, some flowers are not suitable for indoors, and some flowers should be kept away from the crowd. For example, Du Juanhua and Bauhinia contain toxins, which can poison people if eaten by mistake. Narcissus, dripping Guanyin and other leaf juice and flower juice dripping on the skin will cause allergic symptoms such as redness, swelling and pain. And some plants with thorns will accidentally hurt people, so they should be placed where they are not easy to be touched. In short, don't be greedy for more flowers, but choose flowers according to the size, function and needs of your room.

Myth 6: Chasing fame and fortune

Some flower growers think it is necessary to raise famous flowers because of their high ornamental value and great market profit. To this end, they spend a lot of money to buy all kinds of precious flowers everywhere. But the result is often due to the lack of good maintenance conditions and management techniques, flowers will soon die. This not only wastes precious flowers, but also wastes money.

The correct method of flower cultivation is to start with ordinary and low-grade varieties and gradually explore the rules and skills of flower cultivation. Wait until the experience and technology have accumulated to a certain extent before gradually buying rare varieties, so that the chances of successful breeding will be more.

Myth 7: chop and change

Some flower farmers are impatient, always impetuous and try their best to raise flowers. This practice is not only bad for cultivating beautiful flowers and trees with high ornamental value, but also bad for improving flower cultivation techniques.

Flower growers had better choose one or two kinds of flowers and focus on cultivating them in order to gain something.
