2. Spray 1000 times of 70% methyltobujin wettable powder or 800 times of 70% chlorothalonil wettable powder to eliminate the damage, and spray on the leaves every 7 or 8 days.
Improper watering: pay special attention to the water content of flowers and plants before and after flowering. Watering too little, water supply can not reach the flower, will cause bud falling; watering too much, the soil is sticky, the root can not breathe, can not supply nutrients, will also cause bud falling

1. Before watering, first touch the soil. It's better to insert half a knuckle, feel the moisture of the soil, and determine whether watering is needed.

2. Rhododendron, camellia and other newly purchased new year's Eve flowers, which grew in a humid and warm shed before, suddenly brought home, may also fall bud due to sudden environmental change. At this time to ensure that the temperature above 15 ℃, often in the leaves and flowers around the water.

Too much water: too much water in winter, water filled soil pores, the root respiration of flowers and plants will be blocked, can not absorb nutrients well, leading to yellow leaves. This needs urgent rescue, otherwise the flowers and plants will easily rot.
1. If the situation is not serious and there is no waterlogging, you can 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.
Note that the temperature should not be lower than 10 ℃, or it will easily cause frostbite.
2. If the situation is very serious, the root has become soft and black, which has caused rotten roots, it is necessary to immediately cut off the rotten roots, clean up and replace the soil into the basin.
Long term shade: pineapple, Chlorophytum, Money Tree, Lucky Bamboo, Ivy These flowers and plants that you often keep indoors like half shade. They don't need much sunshine, but they can't be shaded for a long time.
Without sunshine for a long time, the leaves can not carry out photosynthesis, which can not guarantee the nutrients of flowers and plants.
Light loving flowers and plants such as meat, in winter can be placed on the windowsill, balcony maintenance, of course, pay attention to the temperature not less than 10 ℃, do not let the cold wind, or winter is easy to cause freezing damage.
Like half shade of flowers and plants such as bamboo, to be placed in a bright indoor, scattering light.
Temperature is too low: Generally speaking, the temperature at home is not less than 10 ℃, most of the common domestic plants can survive the winter safely, but if the temperature is too low or carelessly let the flowers and plants blow to the cold wind, the flowers and plants will easily turn yellow.
Cut off the yellow leaves, improve the temperature of the living environment of flowers and plants, and cover with insulation if necessary.
After bagging, when the temperature is high at noon, flowers and plants should open the bag for ventilation, or they can make a few holes on the bag when bagging to ensure that flowers and plants can breathe normally.

1. Boiling can soften the 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
2. After the basin soil is hardened, you can use the soaking basin method to water the flowers, which can not only ensure that the water is fully poured, but also is not easy to accumulate water in the basin.
The soaking pot method can let water seep into the permeable hole at the bottom of the basin, and can be taken out when the surface of the basin soil is wet. Note that the water in the big pot should not pass the top of the flowerpot.

Fertilization too much: fertilization too much, nitrogen, phosphorus and potassium can not be completely absorbed by flowers and plants, will be combined with the components in the soil, causing soil hardening, hindering the root of flowers and plants to breathe.
In this case, the soil needs to be replaced. The new soil should be loose and fertile. It is better to mix some vermiculite or clean river sand to improve the permeability of the soil.
This situation is generally mechanical damage, mostly insect damage.
1. If there are not many insects, you can consider catching them by hand to avoid using medicine to burn flowers and plants.

This kind of situation is generally caused by improper watering, or the drain hole is blocked, resulting in the pot soil is too wet, the pot moss
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 if they belong to this situation.
Take off the pot to check the condition of soil and root system of flowers and plants. If they are not rotten, put the flowers and plants with soil in the shade to dry, and then re-enter the pot after the soil becomes slightly damp.
