Leaf spot
(author: Nong Botong source: I can plant)
Reason one
Water shortage: if the spots and patches on the leaves are brown and the edges are wrinkled, it is likely to be caused by water shortage p>
(source: Baidu knows)
Cure
On a sunny and warm morning, water the flowers and plants and pour them through along the flowerpot until the water comes out of the permeable hole at the bottom of the flowerpot p>
For indoor shade loving plants such as green pineapple, ivy and asparagus, you can spray water around the leaves and potted plants to moisturize. Note that there is too much meat. Do not spray water on the leaves, which is easy to cause decay p>

Reason two
Burn: when watering flowers and sprinkling water, the water splashes on the leaves. Later, when exposed to the sun, the leaves will be burned by the sun under the concentrated action of water droplets. (author: a280810 source: stepping on the flower forum)
Cure
Move the plant to a ventilated shade and cut off the spotted leaves p>

Reason three
Disease: the spot of leaf spot disease is grayish brown, and the spot is softened. At first, it is a small water immersion spot, and then it slowly spreads to oval and amorphous p>
Cure
1. If flowers and plants are infected with leaf spot disease, the remaining leaves will become pathogens. They must be cut off and cleaned to avoid infecting healthy leaves p>
(author: Nong Botong source: I can plant)
2. Spray 1000 times of 70% methyltobuzin wettable powder or 800 times of 70% chlorothalonil wettable powder on the leaves every 7 or 8 days p>
Falling bud
Reason one
Improper watering: pay special attention to the moisture of flowers and plants before and after flowering. Too little watering, water supply to flowers, will cause bud falling; Watering too much, the soil is sticky, the roots can't breathe and can't supply nutrients, which will also cause bud falling p>
(author: Mulan # source: Flower treading Forum)
Cure
1. Touch the soil before watering. It's best to insert half a knuckle to feel the soil moisture and determine whether watering is needed p>
Whenever watering, it must be thoroughly watered. It is necessary to see that the water can flow out of the permeable hole and then stop p>

2. Rhododendron, camellia and other newly bought new year's Eve flowers grew in wet and warm greenhouses. When they were brought home suddenly, the environment changed suddenly and may also fall buds. At this time, ensure that the temperature is above 15 ℃, and often spray water around leaves, flowers and plants to moisturize p>
Reason two
Insufficient nutrition: flowering is a matter of consuming plant nutrients. If there is insufficient nutrition, it will also cause bud falling p>

Cure
Sparse bud: Flower friends don't care about the bud. Now the bud is broken down to retain nutrients and make the remaining buds bloom better p>
Small and poorly developed flower buds can be removed, and one or two flower buds with dense sides can also be removed as appropriate p>

Yellow leaf
(source: Baidu knows)
Reason one
Excessive watering: if you water too much in winter, the water will fill the soil pores, and the respiration of the roots of flowers and plants will be blocked, so they can not absorb nutrients well, resulting in yellowing of leaves. This needs urgent rescue, otherwise the flowers and plants will easily rot p>
Cure
1. If the situation is not serious and there is no waterlogging, move the flowers and plants to a cool and ventilated place, loosen the soil in time and let the water evaporate as soon as possible p>
Note that the temperature should not be lower than 10 ℃, otherwise it is easy to cause frostbite p>
2. If the situation is very serious and the root has become soft and black, it has caused rotten roots. The rotten roots must be cut off immediately and replaced into the basin after cleaning p>
Reason two
Long term shade: Green pineapple, Chlorophytum, fortune tree, Fugui bamboo and ivy... These flowers and plants often raised indoors by flower friends like semi shade and have no great demand for sunshine, but they can't be shaded for a long time p>
Without sunshine for a long time, the leaves can not carry out photosynthesis, and the nutrients of flowers and plants can not be guaranteed p>
Cure
Light loving flowers and plants, such as meat, can be placed on windowsills and balconies for maintenance in winter. Of course, pay attention to the temperature not lower than 10 ℃, and do not breathe cold wind, otherwise it is easy to cause freezing damage in winter p>
Like semi shade flowers and plants, such as asparagus, should be placed indoors in a bright place with scattered light p>
Reason three
Low temperature: Generally speaking, the temperature at home is not lower than 10 ℃, and most common domestic plants can survive the winter safely. However, if the temperature is too low or the flowers and plants are accidentally blown to the cold wind, the flowers and plants are prone to yellow leaves p>
Cure
Cut off the yellow leaves, raise the temperature of the living environment of flowers and plants, and cover with insulation when necessary p>
After bagging, when the temperature is high at noon, flowers and plants should open the bag for ventilation. You can also make several small holes on the bag during bagging to ensure that the breathing of flowers and plants can be carried out normally p>

Soil hardening
Reason one
Watering flowers with hard water: tap water contains more soluble calcium and magnesium compounds. When watering flowers with tap water for a long time, calcium and magnesium ions are precipitated, which is easy to lead to hardening of basin soil, and the water cannot seep down when watering again p>
(author: beautiful cook, source: Sina blog)
Cure
1. Boiling can soften hard water, so you should try to reduce the direct use of tap water to water flowers. You can use pure water or cold boiled water p>
2. After the potted soil is hardened, the potted method can be used to water the flowers, which can ensure the thorough watering and is not easy to accumulate water in the basin p>
The basin immersion method allows water to seep into the permeable hole at the bottom of the basin and take it out when it is wet on the surface of the basin soil. Note that the water in the big pot should not go over the top of the flowerpot p>

reason 2
Excessive fertilization: if excessive fertilization, nitrogen, phosphorus and potassium cannot be fully absorbed by flowers and plants, it will be combined with the components in the soil, causing soil hardening and hindering the respiration of flowers and plants p>
Cure
In this case, soil replacement is required. The new soil should be loose and fertile. It is best to mix some vermiculite or clean river sand to improve the air permeability of the soil p>
The blade has holes
Cause
This situation is generally mechanical damage, mostly insect pests p>
Cure
1. If there are not many insects, you can consider catching them manually to avoid using drugs to burn flowers and plants p>
(author: nilshuai; source: Orchid bar)
2. If the pest is serious, drug pest control should be considered. The flower protection god can be diluted according to the ratio of 1:200. It is better to be thin than thick. Spray the leaves comprehensively. Then put the flowers and plants in a cool and ventilated place p>
Moss grows on the side of the pottery basin
(author: Huang Guo, source: home of red pottery basin)
Cause
This situation is generally caused by improper watering, or the drainage hole is blocked, resulting in too wet pot soil and moss on the flower pot p>
Of course, if the weather is too humid and the air humidity is high, the pottery basin may also grow moss. Flower friends can see whether they belong to this situation p>
Cure
Take off the pot to check the soil and root system of flowers and plants. If the roots have not yet rotted, you can put the flowers and plants with soil in a cool place to dry, and re-enter the pot after the soil becomes slightly damp p>

If the roots are rotten, the bad roots need to be cut off, cleaned and replanted. The new soil should be loose and fertile with good air permeability p>
