Why do cacti shrink in the fall?

Cactus is a drought-tolerant plant that does not require much water and nutrients. When the temperature is too low, the cactus will go dormant and no longer grow, and the sphere will even begin to shrink and shrink. This is because when the temperature is below 15 degrees, the cactus will gradually go into a dormant state, its growth will stagnate, and the sphere will shrink in size in order to reduce water evaporation.

Therefore, in the autumn when the temperature starts to drop, the water demand of the cactus will also decrease, and the water should be cut off at this time to avoid overwatering that can cause excessive growth or decay of the cactus. At the same time, cacti need plenty of sunlight and a warm environment to maintain healthy growth, and if there is a lack of light or the temperature is too low, cacti are prone to grow or shrink.

Therefore, if you want to keep the cactus ball in a full sphere state, you need to put it in a sunny place, give it the right amount of water and fertilizer, and wait until next spring, when the temperature rises, it can continue to return to a full ball shape.

It's okay, your ball is a dragon king ball, it's very easy to raise, pay attention to don't accumulate water when watering in autumn, it's easy to rot roots. If the temperature is a little higher, then no problem. The landlord is **? It is better to decide on the issue of watering according to the autumn and winter climate of your city.

It depends on what the temperature is like in autumn when it's cold, and it's going to be dormant when it's cold, so you should water less or no watering, as if you are already asleep, and make a basin of water to soak your feet, will you be comfortable? Take it out and let it dry when there's sun.

If you water too often, the roots will be broken.

It may be caused by a lack of water, although the cactus is a drought-tolerant plant, but in order to reduce the evaporation of water during the drought, the cactus will not bloom, and even if the flower buds grow, they will dry up. Take care of the water and fertilizer, and soon the buds will grow again! I've been in this situation before, but now there are two of them, which is very beautiful!

Hope you can see your cactus blossom soon.

It's normal. Some cacti are like swan eggs, and the flowering is long like a suona, which is very chic, but it is rare to see the flowering after a few hours.

Most cacti have a relatively short flowering time, but there are also varieties that have a longer flowering time.

Rest assured, the cactus will not die so easily, usually water less, and it is easy to rot if there is more water.

The cactus balls that have been in bloom for many years and are brilliant and shimmer after a day.

1. Lack of light.

As much as possible, place the cactus in a place where the sun is shining for a long time, not where the light is strongest. For plants to fill in the light, the light time should be extended, rather than because the light is weak to increase the light intensity. Cacti are sun-loving plants, which are strongly masculine, and can only have bright flowers under strong sunlight conditions.

Therefore, if you want to bloom more, you should give plenty of light, especially in winter.

2. Air humidity.

Air humidity at night should be increased and decreased during the day. High air humidity at night is conducive to CO2 intake by cacti. For comrades cultivated in the open air, spray some water appropriately at night.

The high air humidity during the day will reduce the transpiration of plants, increase the moisture content, and form fatness.

3. Watering. Don't look at the cactus drought tolerance, but this does not mean that you can not water, usually to maintain their own water, as long as the root system finds a water threat, it will immediately turn off the gas exchange, which will reduce the amount of growth. Most desert cactus succulents can still have normal gas exchange for a week after a drought, so watering can be done once a week.

4. Fertilization. Most of the cactus succulent cultivation books on the market say that less or no fertilizer is used, which is not comprehensive. Nitrogen fertilizer should be applied appropriately, otherwise the plant will grow slowly or even stop growing. A part of organic fertilizer should be applied when fertilizing, because organic fertilizer releases C02 when decomposing, which will promote the growth of plants.

5. Temperature. The suitable temperature for the growth of cactus plants is 20 30, the highest is not more than 35, and the minimum is not less than 5. In winter, it is safe to overwinter by maintaining a temperature of more than 5, and the drier the potting soil, the more cold-tolerant. The temperature in winter should be relatively stable, and the temperature difference between day and night is too large, which is prone to frost damage.

When the temperature reaches 15 or more in spring, it begins to grow, and when the temperature reaches 35 or more in midsummer, it begins to enter dormancy, and resumes growth in autumn.

6. Flower pots. As much as possible, use flower pots that are ventilated around them, such as purple clay pots and clay pots. If plastic pots are used, they should be cultivated with a medium with larger particles.

For the growth of cactus, don't worry, take your time step by step, and take care of it, and the cactus will thrive!

Why don't cacti grow thick? Before answering this question, we need to figure out why cacti are thick. As we all know, cacti grow in desert or semi-desert areas, where the environment is relatively harsh, barren, arid, and the sun is scorching, in order to adapt to such an environment, cacti usually have to store enough water and nutrients in the body for use in the dry season.

When enough water nutrients are absorbed, the stem becomes hypertrophied. Therefore, the cactus we raise at home is not thick because the living environment is too superior, and the cactus has no sense of crisis and cannot take precautions. So how do you make a cactus thicker?

Here are a few things to keep in mind:

1. Reasonable water control.

Cacti are very drought tolerant, whether it is a potted plant or a ground plant, it must be controlled and cannot always be watered with large water. Let it have a sense of danger, in order to start the function of coping with danger, more water is stored in the body, and the stem is wide and thick. If it is always watered, the cactus will feel that there is no need to store water, and it will grow thin and flat, and only develop vertically and not horizontally.

How do you control the water for the immortals? Generally, when the stems are a little soft when they are pinched, they can be watered. If the stems are hard to pinch, do not water them, no matter how hot the weather is.

After controlling the water in this way for a period of time, the cactus will naturally become fatter.

2. Sufficient light.

Everything grows without the sun, and the cactus is even more so, it loves light. When the light is insufficient, it will grow long, and the stems will become narrow, long, thin, like a jujube stalk, crooked and unsightly. Some flower friends are worried that the light is too strong in summer and the cactus will get sunburned, this worry is unnecessary, the cactus has a layer of waxy substance on the surface, the older the stem, the thicker this waxy substance, this thing can not only reduce water evaporation, but also have the function of sun protection.

Therefore, even if the temperature is 40 degrees, people can smoke from the sun, and the cactus will not get sunburned.

3. Supplement nutrients.

Cacti have a relatively low need for fertilizer, but it is impossible to grow tall and fat without fertilizer. If the cactus at home has not been fertilized for a long time, or has not changed the potting soil for a long time, resulting in insufficient nutrients, even if the water control and light control are reasonable, the stems will become thinner and thinner, and no new stems will germinate. Therefore, it is necessary to fertilize cactus, and apply a little fertilizer with a balance of nitrogen, phosphorus and potassium in the spring and autumn growing season, which has great benefits for promoting the growth of cactus.

Fertilization is best slow-release fertilizer or farmhouse fertilizer, organic fertilizer, ordinary fertilizer is not used well will hurt the roots. I once had a friend's cactus that was going to die or not to live, and when he changed the pot in the spring, he added a layer of farm fertilizer to the bottom of the pot, and the cactus grew crazy that summer.

Hello, cactus not growing can be the following reasons:

1. Breed reasons, the simplest examples: Shitong and Golden Tiger.

The fairy ball is very small, does not grow large throughout its life, and is "precocious" and blooms early.

Golden Tiger Cactus can reach up to 60 years from seed germination to flowering. The sphere is round in the early stage, and cylindrical in the later stage.

It can be seen that the variety determines the size of the sphere.

The subject can take a photo of the plant and upload it, and it will be easy to judge after knowing the variety.

2. The cactus lacks light.

Most varieties of cactus are very light-loving, if it is placed indoors for a long time, it will grow in the early stage of serious lack of light, and then it will grow slowly.

3. Cactus lacks water.

People who sell cacti say that they are easy to raise, and it is good to water less.

However, cactus is also a plant, and it will grow slowly and dry out due to lack of water.

4. Other causes of cactus.

Root rot, root scales, insects, etc. can also cause slow growth.

As a personal suggestion, you can adjust the growth of the plants by changing the soil and placing them.

Withered cacti can be restored. Cactus wilting caused by severe water shortages can be restored by loosening soil and watering. If it is caused by insufficient light, the light intensity should be gradually increased, placed in a place of astigmatism for maintenance, and then basking in the sun after returning to normal.

It can also be caused by rotten roots. It is necessary to prune the rotten part of the cactus bulb root and then replace the pot.

Can the cactus recover from shriveling and wilting?

1. Although the cactus is a drought-tolerant desert plant, it still needs water to grow and survive. If the cactus is left unwatered for a long time, there will be a severe shortage of water, resulting in the shrinkage and atrophy of the cactus. At this point, it is necessary to loosen the soil to restore the porosity of the soil, then water it and place it in a place of astigmatism for maintenance.

Let's continue to dive into the topic of this issue.

2. The lack of light in the cactus can also lead to atrophy. If the cactus is not exposed to light for a long time, it will not have enough energy to survive, and the water in the cells will gradually be lost, and some cells will die, causing atrophy. At this point, it needs to be placed in a place of astigmatism** and then exposed to sunlight after returning to normal.

3. The rotten roots are also one of the reasons why the cactus ball is abrasive and shrinking. The ability of cactus to absorb water and nutrients after root decay will be greatly reduced, resulting in severe water shortage and nutrient deficiency in the aboveground parts of cactus plants, water loss and atrophy of cells, necrosis of some tissues, and dryness and atrophy. In this case, the pool needs to be replaced.

For example, how to change the pot of cactus in the eggplant shed.

When changing potted cactus, first take the cactus out of the soil, clean up the residual soil on it, and cut off the rotten and blackened roots. The cactus bulbs are then soaked in a solution of potassium permanganate for 30 minutes, removed, dried and planted in new potting soil. Then water, compact, and place it in a ventilated place for maintenance.

Through our introduction, I believe that everyone has a deeper understanding of what measures should be taken to recover from the shriveled and atrophied cactus.
