The leaves of asparagus turn yellow

Main reason: too little watering

The biggest reason is that the leaves of asparagus are watered too little

Solution:

1. Pruning

If you find that the leaves of asparagus have turned yellow, there is no other way except pruning. All yellow leaves should be cut off. Don't be distressed. Only in this way can asparagus grow more vigorously

2. Watering

1. After trimming the asparagus, add water to the asparagus in time. Water it once every 2-3 days. Only when the water is sufficient, the asparagus will not have yellow leaves. However, it should be noted that there should be no water in the basin. If it's tap water, it's best to put it overnight before using it. When watering, you can add a little sugar to the water, which can make the leaves of asparagus more green

2. If the air is too dry, it is best to spray water on the asparagus leaves with a watering can, once in the morning and once in the evening, to ensure the air humidity and make the asparagus grow more prosperous

Other reasons:

1. The light is too strong

Asparagus likes a cool environment. If placed in direct sunlight, it will cause yellow leaves. Therefore, asparagus needs to be placed in a bright living room with transparent north and south to receive scattered light

2. Oil fume is too heavy

If you often smoke next to asparagus, or put it in a place with heavy oil smoke, over time, the harmful substances inhaled by asparagus will increase, which will lead to yellow leaves

Gardenia yellow leaf

Main reason: soil alkalinity

Gardenia like acidic soil. The soil in the north is generally alkaline. Gardenia can't adapt to alkaline soil and will produce yellow leaves

Solution:

1. For the pot soil of gardenia, it is best to choose peat soil, rotten leaf soil and river sand, mix them in the ratio of 1:1:1, and then mix some ferrous sulfate solution. In this way, the mixed soil is an acidic soil suitable for gardenia

2. In order to ensure the acidity of the soil, pour 0.2% ferrous sulfate solution or 1:10 alum fertilizer water into the Gardenia soil, about 2-3 times a month. If there is no ferrous sulfate at home, you can also choose to irrigate with vinegar at a concentration of 1:10

Other reasons:

1. Improper watering

Gardenia likes water, but avoid ponding. Too much or too little watering is easy to cause yellow leaves. If you water too much, you need to put the flowerpot in a cool and ventilated place, remove the yellow leaves, and move the position after the soil is dry; If you water too little, the old leaves will turn yellow first and fall off from bottom to top. At this time, you should water them thoroughly

2. Improper illumination

Gardenia likes light. You need to ensure more than 6 hours of light every day. It's best to put it on Nanyang terrace or South windowsill. However, too much light will lead to yellow spots on the leaves. At this time, it can be maintained in a cool place; If the light is too weak and the leaves turn yellow, just put Gardenia under the sun to supplement the sun

Fortune tree yellow leaf

Main reason: improper watering

Fortune trees like warm and humid environment. Too much or too little watering will lead to yellow leaves. Watering too much will make the root system of fortune tree breathe poorly, resulting in rotten roots and yellow leaves; Watering is too little, the surface of the basin soil is only wet, and the soil below is still dry. The roots cannot absorb water, and the leaves will turn yellow from bottom to top

Solution:

1. If you find that the rich tree is watered too much, put the rich tree in a ventilated place near the window and loosen the soil. If the pot soil cannot be dried in a short time, you can pad a layer of sponge or absorbent towel at the bottom of the pot, and replace it when it is wet. You can also use a hair dryer or a small electric fan to blow it. If none of the above methods work, the soil can only be changed

2. If watering is too little and the surface of the basin soil is cracked, watering can be carried out step by step without completely yellowing. First keep the soil surface moist, and then pour it a little for an hour to gradually water it. If the water is poured at one time, it will make the root absorb water and expand, affecting the growth and development

Other reasons:

1. Improper illumination

Fortune trees like sunshine, but they can't be exposed to strong light. Hot sun exposure or long-term shade may cause their leaves to turn yellow. If the leaves of fortune tree turn yellow due to excessive exposure to the sun, it proves that the water in the leaves has volatilized seriously. It's best to put them in a semi shady place, remove all the yellow leaves and water them appropriately. It's good to grow new leaves after the yellow leaves gradually fall off

2. Excessive fertilization

If you fertilize too much because you are worried about the lack of fertilizer, the excess fertilizer will burn the roots of the tree and cause the leaves to turn yellow. At this time, we need to remove the rich tree from the basin, clean up the rotten part, and then replace it with new soil and replant it. Or by watering, slow-release the concentration of fertilizer in the soil can also reduce the symptoms of excessive fertilization

Clivia yellow leaf

Main reasons:

Clivia is drought resistant but not moisture resistant. If watered too much, it will lead to ponding in the basin, rotten roots and yellow leaves

Solution:

1. If the root system does not decay, the Clivia can be placed in a cool and ventilated place without water for 3-5 days to dry the basin soil before subsequent maintenance. If the root system has decayed, the Clivia should be removed from the pot, the decaying root system should be cut off, and then soaked in 0.1% potassium permanganate solution, dried, and then put into the pot again

2. When watering normally, keep the basin soil dry, do not pour, and pour it thoroughly. Watering can be selected at 8-9 a.m. and the tap water can be used after drying for 2-3 days. For 1-2-year-old Clivia, it can be watered once every 5-7 days. For more than 3-year-old Clivia, it can be watered according to the size of the basin and the dry and wet condition of the soil

Other reasons:

1. Excessive fertilization

If the Clivia is fertilized too much, the concentration is too high, or the fertilizer without decomposition is applied, it will lead to yellow leaves. First, stop fertilization and wash the soil with large water to reduce the soil concentration; If rotten roots have been caused by excessive fertilization, change the soil immediately, soak the roots in 0.1% potassium permanganate solution for about 20 minutes, wash them with clean water, cut off the rotten roots after drying, apply plant ash to the wound, and then plant them again

2. Insufficient light

If Clivia is in the shade for a long time, the green color on the leaves will gradually decline, and the leaves will gradually turn yellow. Fluorescent lamps can be used to supplement the light of Clivia; Or transfer the Clivia to the scattered light and slowly accept the light, and the yellow leaves of the Clivia can recover soon

Rose yellow leaf

Main reason: improper watering

If you find that the leaves of rose are dark yellow, or the edges are dry, it is all caused by improper watering

Solution:

1. If the rose is watered too much, the plant needs to be removed from the pot and placed in a cool and ventilated place. After the soil mass is blown dry, it can be put back into the pot

2. Usually, you can water the rose once every 2-3 days. When you find that the pot soil turns white or weigh up the flower pot, you can water it when you obviously feel lighter

Other reasons:

1. Diseases and insect pests

Roses are particularly vulnerable to diseases and insect pests such as red spiders and scale insects. Generally, the leaves are obviously yellow and withered. If you find a red spider growing in a potted rose at home, you'd better isolate it quickly, because the red plants reproduce very fast, and isolation can effectively avoid mutual infection. After that, pyridaben, jinmanzhi and other drugs can be sprayed alternately to avoid drug resistance of rose

2. Insufficient light

Roses like sunshine. If the light is insufficient, it is easy to cause the leaves to turn yellow. It's best to put the rose on the sunny Nanyang terrace or windowsill and receive at least 6 hours of light every day; If possible, it's best to put it in the courtyard

Chlorophytum yellow leaf

Main reason: improper watering

If you water Chlorophytum too much, it will cause poor drainage in the basin, resulting in ponding, Chlorophytum root system can not breathe, and the leaves are easy to turn yellow. If the Chlorophytum is watered too little, it will lead to water shortage in the root and the lower leaves will soon turn yellow

Solution:

1. Chlorophytum is usually watered once every 5-7 days. If the temperature is high in summer, it can be watered once every 3-5 days. In winter, it can be watered once every 10 days. The watering should be thorough and the drainage should be smooth. The best time to water is in the morning or evening. Don't water when it's hot at noon, otherwise it's easy to evaporate and it's also white

2. If the air is too dry, spray water on the blade with a watering can to increase the air humidity and prevent the blade from drying

Other reasons:

1. Insufficient light

If Chlorophytum is not exposed to the sun, it will reduce the chlorophyll in its leaves and the leaves will begin to turn yellow. The Chlorophytum can be exposed to scattered light for 4 hours a day, or it can be placed under an indoor incandescent lamp to receive scattered light, or on a balcony or windowsill. When the light is strong in summer, the Chlorophytum should be placed in the shade and not exposed to the sun

2. Undernutrition

The nutrients needed by Chlorophytum are basically obtained from the soil. If the basin soil is not replaced for a long time, the nutrients in the soil will be absorbed by the root system of Chlorophytum, which will lack nutrition and lead to the yellow leaves of Chlorophytum. You can apply rotten bean cake fertilizer or liquid fertilizer every 7-10 days, or you can make organic fertilizer from domestic waste such as bone residue and eggshell; If there is a serious lack of nutrients in the basin soil, you can only choose to change the soil and basin
