Money TreeMost common cause: Improper wateringThe money tree is afraid of water. Once it is watered too much, the soil will become airtight, the roots will begin to rot, and the leaves will begin to turn yellow. Solution: 1. When watering the money tree in spring and autumn, you should follow the principle of watering when the soil is dry and keep the soil moist. About 1-2 times a month is enough. 2. The money tree grows faster in summer, the evaporation of its leaves is relatively large, and its demand for water is relatively high. Therefore, you can water it more often in summer, about once every 7-10 days. 3. In winter, water the plant about once a month. Other reasons: Improper fertilizationWhen fertilizing the money tree, if the fertilizer used is uncomposted raw fertilizer, or if too much fertilizer is applied, it will cause damage to the root system of the money tree, causing the leaves to turn yellow and fall off. Workaround1. May to September is the peak growth period of the money tree. At this time, you can apply fertilizer once every half a month, mainly with decomposed liquid fertilizer or mixed flower fertilizer. 2. For daily fertilization, you can choose to dig a 2cm hole, bury a few grains of compound fertilizer, and let the fertilizer be slowly absorbed. ChlorophytumMost common cause: OverwateringChlorophytum is afraid of waterlogging. If you water it too much, the soil in the pot will not drain well, the roots will not be able to breathe, and the leaves will easily turn yellow. Solution:1. If the spider plant is overwatered, you need to loosen the soil in time to evaporate the excess water. 2. In daily watering, pay attention to watering when the soil is dry and wet. You can wait until the surface of the soil is dry, then insert a toothpick into the soil. If the toothpick is also dry, it is time to water the plant. 3. In summer, the temperature is high and the evaporation is large. Water the plants about once every 3-5 days and make sure they are watered thoroughly. Other reasons: Improper lightingIf spider plants are kept in a dark environment for a long time, the chlorophyll in their leaves will decrease, and then they will slowly turn yellow; if spider plants are exposed to the sun, the leaves will also turn yellow. Workaround1. Allow the spider plant to receive at least 4 hours of light every day, or you can place it under an incandescent lamp indoors for maintenance. 2. If the light is too strong in summer, provide appropriate shade for the spider plant. In winter, you can place the spider plant on the south balcony or south windowsill to allow it to receive sunlight. asparagusMost common cause: Improper wateringAsparagus fern needs a moist environment to grow. If it is watered too much, the roots will rot and the leaves will turn yellow and fall off. If it is watered too little and the soil in the pot is dry for a long time, the leaf tips will turn yellow and the leaves will fall off. Solution:1. In spring and autumn, watering once every 3-5 days is enough, and in winter, watering once every 7-10 days. 2. The growth environment of spider plants requires very high air humidity. You should often spray water on the leaves of asparagus fern and the surrounding air to maintain a high air humidity. Other reasons: Improper lightingAsparagus fern prefers a semi-shaded environment. If it is exposed to strong light, its leaves will turn yellow. However, if asparagus fern is placed in a completely shaded environment, its growth will be weak, its nutrients will be reduced, and its leaves will turn yellow. WorkaroundPlace asparagus fern in a brightly lit living room so that it can receive appropriate scattered light. It will not be overwhelmed by the sun, but will also receive sufficient sunlight needed for growth. CliviaMost common cause: Improper lightingIf the Clivia is exposed to strong light, yellow spots will appear on its leaves, causing the leaves to wilt and turn yellow; however, if it is placed in a completely shaded place, its leaves will turn yellow due to lack of photosynthesis and inability to absorb nutrients. Solution:1. Clivia grown outdoors should be placed in a shaded place to avoid exposure to the sun. At the same time, yellow leaves should be removed to reduce nutrient consumption. 2. For indoor Clivia cultivation, it must be placed in a brightly lit living room and receive a certain amount of scattered light to maintain its growth and development needs. Other reasons: Dirty leavesThe leaves of Clivia are very large and have many stomata on them. If too much dust accumulates on the leaves, the Clivia will not be able to breathe and the leaves will easily turn yellow. Workaround1. Clean the leaves of Clivia, remove all dust and other stains, and keep the leaves clean. 2. You can also use expired beer, mix it in a ratio of 1:1000, then dip a soft cotton cloth in the solution and gently wipe the leaves to make them shiny. RoseMost common cause: Powdery mildewPowdery mildew is a common disease of roses. A layer of white powder can be found on its leaves and tender shoots. If powdery mildew is severe, it can cause the leaves to turn yellow and fall off, and may even affect growth and flowering. Solution:1. Powdery mildew is mainly caused by potting soil. If the potted roses in your home have powdery mildew, you need to change the soil. 2. You can cross-spray the plants with 50% thiophanate solution every week until the powdery mildew disappears. Other reasons: Improper wateringToo little watering will cause the edges of the rose leaves to dry out and wither, and the old leaves will begin to wither from the bottom up, while the new leaves will remain normal. Too much watering will cause the leaves to turn yellow and lose their luster, and the branches will become thin and weak. Workaround1. If you water the rose too much, take the plant out of the pot and place it in a cool and ventilated place. Wait until the soil is dry before putting it back into the pot. 2. When watering, follow the principle of not watering unless the soil is dry, and watering thoroughly when you do. Wait until the soil in the pot turns white before watering. Water thoroughly at one time to keep the soil moist. GardeniaThe most common cause: Improper lightingToo strong light will cause yellow spots to appear on the sunny parts of the gardenia leaves; insufficient light will cause the leaves to turn yellow and fall off. Workaround1. If the light is too strong and yellow spots appear on the leaves, place it in a shaded place for a period of time and it will recover. 2. If the leaves turn yellow due to insufficient light, just put it in the sun and get some additional sunlight. Other reasons: Improper fertilizationToo much fertilizer will cause the leaves to lose their luster and the old leaves will begin to turn yellow and fall off; insufficient fertilizer will cause the entire plant to turn yellow. Solution:1. If too much fertilizer is applied, stop fertilizing immediately. In serious cases, the soil should be flushed to reduce the concentration and reduce damage to the root system. 2. If you apply too little fertilizer, you should frequently spray 0.2%-0.5% ferrous sulfate aqueous solution on the leaves for prevention and control.
