I have a pot of cactus, about 5-6 centimeters in diameter. There are several small balls growing on it. Some of them have fallen on the soil. How should I raise these small balls?

Welcome to Dadingchuan Flower House when you are free, welcome your presence! Cactus flowers are divided into two major categories in cultivation: terrestrial cacti and epiphytic cacti. These two types of cactus flowers have very different requirements for temperature, light, and moisture in their overwintering sites. But the author believes that their overwintering management should start in autumn. After mid-autumn, palm plants should receive as much light as possible. After entering late autumn, watering should be gradually controlled until it is stopped. If necessary, a small amount of potassium chloride solution can be applied to increase the concentration of plant body fluids and enhance cold resistance. From late autumn to early winter, do not rush to bring palm flowers into the house too early. Instead, try to keep the plants outdoors to receive full sunlight during the day and low-temperature exercise at night. If there is no cold wave, palm flowers can be placed indoors only when the lowest temperature drops to 4°C at night. Don't take a break in between. Palm flowers that have been treated in this way generally have enhanced tolerance to low temperatures, which is beneficial to overwintering. : I2 r# R, v' z7 ~7 i6 B

% F* g( r/ d; _ g! After winter, watering should be absolutely prohibited and the pot soil should be kept dry to encourage it to enter a dormant state. If the temperature is not lower than 2℃-5℃, palm plants can survive the winter safely. Strong. If improper watering in winter breaks their dormancy and restores their physiological activity, the plants' cold tolerance will be reduced and they will be susceptible to frost and rot. If the room temperature is too low during the winter, the plants can be covered with plastic. Cover and keep warm. If necessary, the plants can be wrapped in cotton and straw and stored in wooden boxes and cabinets. Even if the temperature is below 0°C, flowers can be safely grown at home. In the case of limited space and poor conditions, after winter, when the pot soil is dry, the plants can be removed from the pot soil, and the bare roots can be wrapped with cotton straw and stored in a box or cabinet, which saves space. , and keep it warm. When the temperature rises to 10°C, remove the wrapping material from the plant, repot it, place it indoors and in a dry place, so that it can gradually adapt to sunlight, and spray water appropriately at noon to allow it to gradually resume growth. Although this will have some impact on the growth of the plants in the coming year, it is also a good way to survive the winter for families who lack space and have poor insulation facilities. p>7 r o# O8 E) x Epiphytic cacti are native to tropical rainforests with high air humidity, such as epiphyllum, arrow lotus, crab claw, etc. They also need higher temperature and air humidity in winter, and there is no dormancy. Therefore, overwintering management is more difficult than for terrestrial cacti. It is necessary to create an ideal overwintering environment for them. The author installed a 5 cm thick glass box next to the south-facing window, with a layer of charcoal ash laid on the bottom of the box. A 100w bulb is used for heating. Place the cactus in a box, cover it with plastic film, and bury the pot in charcoal ash. When the weather is fine, lift the film appropriately for ventilation. If the weather is bad, cover it with plastic film and cover it if necessary. Put on a quilt or straw curtain and light the bulb for heating. Even on a sunny night, the glass box should be covered with a straw curtain or quilt to keep the temperature inside the box at 12℃-13℃. Water and keep the pot soil in a semi-dry state. You also need to sprinkle water on the walls of the glass box as appropriate to maintain a greater air humidity in the glass box. This can meet the water needs of epiphytic cacti and maintain low-level growth of the plants. , which is conducive to the growth and flowering in the second year. Here, if there is no glass box, using a double-layer plastic film to build an insulation shed for the same management can also make epiphytic cacti survive the winter safely.

So, how to grow them well. What about cactus? The author thinks there are the following aspects: ' B3 Q- D9 v) N4 E& b6 r

Temperature Prickly pear likes high temperature and dry environment. In winter, the room temperature should be kept above 20℃ during the day, and the temperature at night should not be Below 10℃. Too low a temperature can easily cause root rot, but too high a temperature can easily cause scale insect damage. 3 k6 z( g4 c1 @% n2 L

Light cactus requires sufficient sunlight, but it cannot be exposed to strong light in summer and needs to be properly shaded. For indoor cultivation, it can be illuminated with light to make it grow robustly.

( ?/ w/ s0 w0 _7 ]( ^Soil Cactus is suitable for growing in sandy loam soil with good drainage. Artificial culture soil is often used for indoor cultivation. It is usually prepared by mixing half and half of peat soil and fine sand; it can also be used after crushing. Add fine sand to the pine needles, and plant them in the prepared culture soil. The soil is "dry and wet". It is best to use water that has been dried.

* F/ C& p5 W! \When fertilizing the cactus, add a small amount of base fertilizer, such as water chestnuts, to the bottom of the pot. slices, bean cakes or sesame paste residue.

During the growth period, fermented organic liquid fertilizer should be irrigated every half month (the concentration is preferably 20%), and the fertilizer concentration should not be too high. / w) r5 Diseases can be sprayed with carbendazim or thiophanate; insect pests can be killed by spraying dimethoate. No matter what kind of liquid is sprayed, it must be done outdoors.

' The specific method is: first cut off the top of the rootstock, cut the base of the scion crosswise, and then tie the two with a string.

When the aging yellow color appears, use a brush to apply undiluted Yun Da 120 times to the ball to make the yellow color fade away. This is my experience. Yunda 120 is a plant growth regulator that contains hormones and is harmless to cactus at high concentrations.

In winter, it should be watered once every 2-3 months. Note that it must be watered thoroughly when watering; when changing pots, Do it in spring. The newly repotted cactus should not be watered immediately, but should be watered after a week. Cultivation of cactus should be done in a flat-bottomed clay pot. The soil inside should be mixed with a ratio of 1 part sand, 1 part soil and 1 part bone meal. Apply once a year. 2 times of thin fertilizer, so you can grow cactus well.

Cactus It is native to Argentina and southern Brazil. It is a perennial succulent plant. Its stems are spherical, solitary or clustered, and the old plants bloom in summer. The flowers are borne on the sides of the sphere. The flowers of most varieties are trumpet-shaped and white. , fragrant and fleshy. Prickly pear loves light, but avoids direct sunlight for a long time in summer. It is not suitable to be kept indoors for a long time. It requires moderately fertile, well-drained and calcareous sandy loam. The propagation of prickly pear is mainly done by cuttings. Can be grafted. During the growing season, the pods can be peeled off from the mother ball and planted. The pods can also be grafted onto the tops of other columnar or vine-shaped cactus to cultivate new landscapes. Potted cactus can be grown with leaf mold or garden soil. 3 parts each of coarse sand and 1 part plant ash are mixed into the prepared culture soil. It is best to pot and repot the pot in a size that can accommodate the sphere and have a slight gap when potting. Use a layer of broken tiles or gravel about 3 cm thick to facilitate drainage. The appropriate planting depth should be that the root neck of the ball is level with the soil surface. Do not water the newly planted cactus. Just spray water 2 to 3 times a day. After half a month, you can water a small amount, and after about a month of new roots growing, you can gradually increase the amount of watering. When planting, you should pay attention to watering the cactus to keep the pot soil from being too dry. The lower the temperature, the more important it is to keep the pot soil dry. As the temperature rises, plant dormancy is gradually lifted, and the amount of watering should be gradually increased. However, in the hot summer, watering should be properly controlled and the potted flowers should be placed in a shaded place. After the hot summer days and the weather turns cooler, normal watering should be resumed. Apply thin liquid fertilizer or compound flower fertilizer every half month or so during the growing season, and stop fertilizing in winter and hot summer. In addition to shade in summer, you should also pay attention to good ventilation. Insufficient light, excessive shade, or too much fertilizer and water during cultivation can lead to failure to bloom. In northern areas, when the weather warms up in spring, potted flowers can be placed outdoors in a sunny place for maintenance. Before winter, they can be moved indoors and placed in a sunny place. If the room temperature is kept above 5°C, they can survive the winter safely.

2 d( x* I: Y4 n The cultivation and management of cactus is simple, the main thing is to master the watering. Repot the pot in early spring every year. When changing the pot, cut off part of the old roots and let them dry for 4-5 days. Planting should not be too deep, and the root neck of the ball should be level with the soil surface. Do not water the newly planted cactus immediately. Just spray water mist 2-3 times a day and water lightly after half a month. When new roots have emerged, the amount of watering can be gradually increased. During winter dormancy, watering should be controlled and the pot soil should not be dry. In rooms with good heating conditions, normal watering can be done in the morning on sunny days. As the temperature rises, the frequency and amount of watering can be gradually increased. It requires a high temperature and high humidity environment, but watering should be appropriately controlled during hot and rainy seasons, and placed in a well-ventilated shaded place after the hot weather. Return to normal watering. Apply decomposed thin cake fertilizer every 10 days or half a month during the growing season. There is no need to fertilize in winter.

After autumn, the temperature continues to drop, especially at night. When there is a cold snap, early frost sometimes occurs at night. At this time, the cactus blooms Physiological activities tend to slow down, and the water consumption of the sphere is also significantly reduced, so watering must be controlled. If it is sunny and warm weather, watering is usually twice a week. As the temperature turns cooler in autumn, watering is done once a week or once every two weeks. , Water evaporates slowly on cloudy and rainy days, so avoid watering, otherwise the soil will be too wet, roots will easily rot, and the cactus will die. After autumn, cactus cannot be fertilized more. Generally, it is appropriate to fertilize liquid once a month. Fertilization should be stopped during the Cold Dew Festival. If fertilization is applied at this time, the cactus will continue to grow, and the growing part of the ball will be tender and its cold resistance will be reduced. In late autumn, there is a huge temperature difference between day and night, and the tender cactus spheres are prone to frost damage.

1 g9 ?( G5 s- \0 i In early winter, when the weather turns cold, the cactus will be moved indoors to a place with common sunlight. If the temperature is lower than 5℃, the smaller spheres can be covered with can bottles. If the cactus can't be filled in cans and bottles, you can use a plastic bag to cover the entire pot; if there are more cactus, you can nail a wooden box (cardboard box is also acceptable) according to the number of balls, put the balls in the box, and then cover it with plastic film Cover it up, and make sure the box is sealed and not breathable. It is best to install a 40-watt light bulb in the box. When the weather forecast temperature reaches zero degrees, turn on the light at night to keep warm, and then use an old cloth to make a cotton cover and put it on the outer layer of the ball box. In this way, the triangle can be safely kept warm during the winter. In sunny and windless weather, you can often expose it to the sun, which will form a warm microclimate inside the cover. In severe cold weather, do not remove the plastic film. Start watching the ball, because the ball and the triangle are suddenly hit by the cold wind, the ball will shrink and the triangle will freeze. You must pay attention to leaving the house in spring. The weather is changeable in spring, so don't rush out of the house too early, and don't water in early spring, otherwise all the hard work of the winter will be ruined. It must be done before and after Grain Rain. , the temperature has stabilized before it can be moved outdoors for normal maintenance and management.
