What to do if the cactus turns yellow (causes and treatment methods) A complete collection of cactus propagation methods

Cactus can survive strongly in the desert, which shows that its vitality is very tenacious. Many novice flower growers will choose such a strong self-survival ability. However, the growth environment of domestic cactus is still very different from that of nature, which leads to some problems in the process of cactus culture. Today, let's take a look at the causes and solutions of cactus yellowing.

What to do if the cactus turns yellow (cause and treatment)

1. Overwatering. The basin soil has been in an over-wet state for a long time, in which the cactus is extremely anoxic, and the cactus gradually rotates, hindering the normal absorption of nutrients and water, so the leaves turn yellow and fall off, so the watering should be stopped and the application of fertilizer should be suspended to keep the soil aerated.

2. Drought and dehydration. On the contrary, this is due to the wet and dry watering of flowers, which affects the water absorption of cactus, resulting in dark yellow leaves without luster, gradually withering and falling off from the bottom to the top. At this point, stop watering or spraying water and keep it appropriate to gradually recover.

3. Lose weight for a long time. If the soil has not been changed for a long time, the pot should be poured in time and the compound fertilizer should be increased gradually.

4. Excessive fertilization. Due to excessive fertilization, resulting in the gradual fall off of the old leaves, at this time to stop fertilization, and an appropriate amount of water, immediately pour the basin, wash the soil with water.

5. It is hot and hot. The cactus needs to be moved to a cool and ventilated place in time.

6. Excessive shade. Due to the lack of sunlight absorption caused by long-term storage in a cool place, it is necessary to transfer to a ventilated sunny place in time.

7. Soil and water is alkaline. In the northern areas where the soil and water is alkaline, the picture lacks soluble iron, so the needles will gradually turn yellow. It is necessary to pour alum and fertile water in time.

8. Airtight. Reasonable application of pruning to make it transparent, because the branches and leaves are luxuriant, it is easy to cause the leaves to fall off, so pay attention to ventilation and light transmission.

9. The air is dry. If the air is too dry, you should pay attention to spraying water and appropriately increase the humidity of the air.

10. Improper temperature. Due to the changes in the four seasons, the room temperature will also change with it, pay attention to adjust the appropriate room temperature in time.

11. The soil is sour. The loss of chemical elements in the soil leads to the acidity of the soil, which requires the application of alkaline solutions such as calcium, magnesium and phosphorus.

12. Diseases and insect pests. Due to the pathogen is easy to cause leaf spot disease, resulting in branches and leaves withered and yellow, timely spray control.

13. Strong sexual stimulation. The concentration of pesticide spraying is too high, which leads to toxic gas pollution and overall death. Pesticides should be used reasonably to prevent air pollution, make correct judgment and prescribe the right medicine.

A complete Collection of breeding methods of Cactus

1. Cutting propagation of cactus.

In the cuttage propagation of cactus, it is necessary to intercept 1 to 4 stem nodes or big branches that can be branched as cuttings; before cutting, the cuttings should be dried for three days.

Prepare cutting substrate: use nutritious soil or river sand or peat soil as cutting materials; select the substrate and directly put the sun-dried cuttings into the soil. After inserting, you should keep it in a warm and sunny place, pay attention to less watering, and wait for it to take root and sprout.

2. Seed propagation of cactus.

First of all, you can pollinate the flowers of the cactus, with your help, as long as you use a cotton swab to stick the pollen to the pistil; after a period of growth, the fruit will mature, and then the seeds can be taken out and cleaned.

After cleaning, you need to wrap the seeds with gauze; then prepare the basin soil and pour water, so you can sow the seeds in the basin soil and keep it in the dark. After the seedlings are issued, they can be transplanted, planted and maintained.

3. Grafting propagation of cactus.

In the grafting breeding, we should first choose the strong germ-free seedlings, first cut off the tip, and then peel off the outer skin. Then prepare the well-growing cactus plant as an auxiliary rootstock, and then cut off the bottom of the seedling to let the ball core exposed.

Can the fruit of cactus be eaten?

The fruit of cactus can be eaten, it tastes cool and crisp, but we should pay attention to the fact that not every kind of cactus fruit can be eaten according to whether it is an edible variety, so when you see the fruit of cactus again, because you don't know its kind, you'd better not eat it randomly.

The function of cactus fruit

1. The pulp is rich in trace elements, proteins, amino acids, vitamins, polysaccharides, flavonoids and pectin, all of which are beneficial to the human body.

2. The fruit can be eaten as food, it can be peeled and eaten directly, or it can be fried into a side dish.

3. It also has the effect of dispelling dampness and reducing fever, promoting qi and activating blood circulation, invigorating muscle and so on.

4. The fruit can also promote the expansion and regeneration of normal fiber cells in the human body, help injured people heal the wound, and remove the bacteria that inflame the wound.

5, the fruit can extract substances that can accelerate wound healing, make skin soft and delicate, place dry skin, reduce wrinkles and so on, which can not only treat wounds, but also beautify and nourish beauty.

Although the cactus is more tenacious, it should pay more attention to it in the process of breeding. After all, water, soil and light are the necessary conditions for any plant to survive. Give the cactus a suitable growth environment, may also be able to grow fruit, its fruit has a very high edible value and medicinal value.
