Do you like to raise potted plants? do not spray water on the leaves of these plants, or they will die.

The air is relatively dry in spring, and many flower lovers like to spray water on the flowers to make them grow more watery and clean the leaves. But some flowers, if you spray water on the leaves will cause rotten leaves, rotten core, serious will directly die to show you! Come and see which flowers can't spray water on the leaves. Begonia can be said to be one of the most popular flowers in China, so many people raise crabapple flowers at home, especially the four seasons crabapple, which has the advantages of round plant type, many and dense flowers, easy to plant with other flower bed plants, and long viewing period of flowering in four seasons, so it is more and more popular. The four seasons crabapple likes a warm and humid environment, and is afraid of cold, early morning, extreme heat and waterlogging, so it grows best in a semi-overcast, humid and warm environment. Autumn crabapple of the four seasons has a long flowering period, many colors and rich changes, so it is a kind of beautiful flowers and leaves. It is not only suitable for outdoor cultivation such as gardens and flower beds, but also a good decoration for indoor family desks, coffee tables, desks and shop windows. After Qingming Festival, potted plants can be moved to outdoor shade for maintenance. East China should be maintained in full shade from April to October, but it is best to see a little sunlight in the morning and evening. If the leaves are found to be curled and scorched, this is a symptom of sunburn. After arriving at Frosts Descent, it is necessary to move into the indoor anti-freezing to keep warm, otherwise suffer frost, will freeze to death; indoor furnishings should be placed in the sunny place. If the room temperature lasts above 15 ℃ and topdressing is applied, it can still blossom. Light, water, fertilizer, temperature and heart picking are the key to growing begonia in four seasons. After planting, the four seasons begonia can be exposed to direct sunlight in early spring, and should be properly shaded with the increase of sunshine.

At the same time, attention should be paid to the management of water. Too much water is easy to produce rotten roots, rotten buds and rotten branches; high temperature and humidity are easy to produce various diseases. After planting slow seedlings, apply liquid fertilizer every 10 days. Timely pruning long branches and old branches to promote new lateral branches, strengthening pruning is conducive to the beauty of plant shape. The soil conditions of cultivation require neutral or slightly acidic soil rich in humus and good drainage, which is afraid of both drought and water stains. Spring and autumn is a growing and prosperous period of soil that needs to contain more moisture, watering it in time and keeping it moist. The requirement of watering work is "two more and two less", that is, spring and autumn are the periods of growth and flowering. The moisture should be more appropriate; the basin soil is slightly wetter; in summer and winter is the semi-dormancy or dormancy period of the four seasons begonia, the moisture can be less, the basin soil is slightly drier, especially in winter, and the basin soil should always be kept slightly dry. Watering time should also be noted in different seasons, watering in winter should be carried out in the sun around noon, and summer watering should be carried out in the morning or evening, so that the temperature difference between temperature and basin soil is small, which is beneficial to the growth of plants. The principle of watering is "do not dry, do not water, dry is thoroughly". Four seasons crabapple likes the humid environment, but in the hot summer, the basin soil should be slightly moist. Watering should not be fixed several times a day or once a few days, but should pay attention to observe the dry and wet condition of the basin soil at any time. It can be watered when the basin soil turns white, and the amount of water should not be too much. Watering time around 9 o'clock is better, as far as possible not dry, watering thoroughly, but can not wait until completely dry again. Its leaves can not be sprayed with water, if spraying water on its leaves, it is easy to block the villi stomata on its leaves, after blocking, it is easy to have problems, such as rotten leaves, diseases and insect pests and so on. Therefore, the four seasons crabapple should be watered slowly along the edge of the basin when watering.

Cactus, commonly known as grass ball, is a perennial succulent succulent herb of cactus family. The stem is spherical or oval, green, and flowers are born in longitudinal thorns. Cactus flowers usually bloom in the early morning or evening, lasting from several hours to a day. Cactus is a kind of stem, leaf and flower with high ornamental value. It is a fine art of hydroponic flowers. It usually grows in dry, rainless desert areas. Cactus is a natural air freshener, which can not only absorb ultraviolet rays, but also absorb dust and purify the air. And the cactus releases carbon dioxide during the day and absorbs carbon dioxide and releases oxygen at night, which helps people sleep. The time of watering is early morning in summer, sunny weather in winter, morning and evening in spring and autumn. In general, do not sprinkle water from the top, or there will be ugly spots on the sphere over a long period of time. In general, watering must be fully watered, so the soil must be often loosened to make the basin soil easily and evenly absorb enough water. Summer is the cactus growing period, with high temperature and high water demand. Must be fully watered, should be carried out in the morning and evening when the temperature is low, hot at noon, watering is easy to cause ball burns. In the hot and rainy season, watering should also be controlled properly. For those cactus with sunken tops, be careful not to pour water into the depressions so as not to cause decay, especially in the evening. Winter dormancy should be controlled watering, in order to keep the basin soil not too dry, the lower the temperature, the more to keep the basin soil dry. Adult big balls are more resistant to drought than seedlings. Watering in winter should be carried out on a sunny morning. With the increase of air temperature, the plant will gradually break away from dormancy, and the watering times and amount of water will gradually increase. Cactus water can not be sprayed on the ball, even when watering can not get water on the ball, otherwise it is easy to cause cactus fester, can not survive. And cactus watering must wait until dry and then thoroughly watered, but also be careful not to let cactus stagnant water, because stagnant water is easy to let cactus rot roots.

Cyclamen alias radish begonia, rabbit ear flower, rabbit flower, a crown, bonspark, petal lotus, is Primulaceae, cyclamen perennial herbs, leaves from the top of the tuber, heart-shaped, ovate or kidney-shaped, leaf serrulate, leaf surface green, with white or gray halo spots, leaf back green or dark red, petiole longer, reddish brown. Cyclamen is a widely cultivated flower, which is suitable for indoor flowerpots and greenhouse in winter. Some cultivated species of cyclamen have strong aroma, while others have light or no aroma. Cyclamen has some contradictions in water absorption. It likes the moist environment very much, but it is afraid of too much water, so when we water it, we should water it appropriately once a day to maintain the wettability of the basin soil, and at the same time control the amount of water watering. Water must not accumulate on the basin soil so as not to corrode its roots. Spray more water for it in summer to ensure normal water absorption. Cyclamen is a more fertile plant, but it likes thin fertilizer, especially in its growing period, we give it thin fertilizer every ten days or so, and we have to apply liquid fertilizer again when cyclamen is pregnant. Try to apply less fertilizer during the flowering period, even if you apply a thin fertilizer once in a while, do not apply nitrogen fertilizer. When fertilizing, you should be very careful not to pour fertilizer and water directly on the flowers and leaves, otherwise it will be easily corroded.

Paulownia likes to grow in warm, moist, semi-shaded, bogey direct light and loose, fertile and acidic sandy soil rich in humus. During the growing period, the suitable temperature was 20: 25 ℃, and it was not cold-tolerant. It was dormant when the temperature dropped to about 5 ℃ in winter, and the normal growth of the plant would be affected when the temperature was too high. When the temperature was more than 30 ℃ in summer, the plant would be semi-dormant. Growth period requires high air humidity, do not like floods, to avoid Rain Water intrusion. Winter dormancy period needs to keep dry, such as humidity is too high or temperature is too low, the tuber is easy to rot. Watering: large paulownia flowers, leaves are fluffy, once stained with water droplets, it is very easy to rot, so avoid spraying water on the flowers and leaves. It is best to use the immersion method to water. Usually appropriate amount of watering, too much is easy to cause tuber rot, leaves withered and yellow, or even the whole plant death. During the period of high temperature in summer, it should be watered once or twice a day, and rain must be avoided during flowering. Soil: paulownia likes loose, fertile and good water retention humus soil, which should be cultivated with slightly acidic soil rich in humus and loose. It is often prepared with 1 part perlite, 1 part of river sand and 3 parts of rotten leaf soil plus a small amount of rotten and sun-dried fine broken poultry manure. Potted paulownia is commonly used as a mixed substrate of rotten leaf soil, coarse sand and vermiculite. Temperature: the suitable temperature for growth is 10-25 ℃. There are different requirements in different seasons, 18: 25 ℃ from January to October, and 10: 12 ℃ from October to January. The suitable temperature can make the leaves grow luxuriantly and green, and the flowers are large and bright. When the plant is withered and dormant, take out the bulb and hide it in the slightly moist sand. Lighting: paulownia is a semi-positive plant, usually should be properly shaded to avoid direct light. There should be plenty of sunshine in the seedling stage in winter, and it must be carefully maintained in a ventilated shade shed with scattered light in summer, the light in the growing period should not be too strong, the sunshading time should be properly prolonged when flowering, and the basin soil should be kept slightly dry during the dormant period in winter.
