Rescue and treatment

On a sunny and warm morning, water the flowers and plants and water thoroughly along the flowerpot until the water seeps through the hole at the bottom of the flowerpot.

For green pineapple, ivy, asparagus and other indoor semi-shade plants, you can sprinkle water around the leaves and potted plants to moisturize. Pay attention to succulent plants can not sprinkle water on the leaves, it is easy to cause rot.

Reason two

Burns: when watering flowers and watering, water splashes on the leaves, and then when basking in the sun, under the concentrated light of water droplets, the sun burns the leaves. (author: a280810 Source: step Huaxing Forum)

Rescue and treatment

Move the plant to a ventilated shade and cut off the spotted leaves.

Reason three

Disease: the spot of leaf spot is grayish brown, the spot softens, at first it is a water-immersed spot, and then it slowly spreads to oval and unshaped.

Rescue and treatment

1. If flowers and plants are infected with leaf spot disease, the residual leaves will become pathogens. Be sure to cut them off and clean them up to avoid infecting healthy leaves.

2. It can be sprayed with 1000 times of 70% methyl topiramate wettable powder or 70% chlorothalonil wettable powder and sprayed on the leaves every 7 or 8 days.

Falling bud

Reason one

Improper watering: special attention should be paid to the moisture of flowers and plants before and after flowering. Too little watering, lack of water supply to flowers, will cause buds; too much watering, heavy soil, roots can not breathe, unable to supply nutrients, will also cause buds.

Rescue and treatment

1, before watering to touch the soil, it is best to insert half of the knuckles, feel the soil moisture, to determine whether it needs watering.

Whenever watering, be sure to water thoroughly, to see that the water can flow out of the hole and then stop.

2. Cuckoos, camellias and other newly bought New year's flowers, which were previously grown in a moist and warm greenhouse, are suddenly brought home, and the environment changes suddenly, and they may also drop buds. At this time, it is necessary to keep the temperature above 15 ℃, and often spray water around the leaves and flowers to moisturize.

Reason two

Insufficient nutrition: flowering consumes a lot of plant nutrients, and if it is not nutritious, it will also cause buds to fall.

Rescue and treatment

Shulei: flower friends, don't feel sorry for the bud. The purpose of getting rid of the bud now is to retain nutrients and make the remaining buds bloom better.

Relatively small, stunted buds can be removed, and buds with denser sides can also be removed according to the situation.

Yellow leaf

(source: Baidu knows)

Reason one

Too much watering: too much watering in winter, water filled with soil pores, flowers and plants root respiration will be blocked, can not absorb nutrients well, resulting in leaves yellowing. This needs emergency rescue, otherwise the flowers and plants are easy to rot.

Rescue and treatment

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 volatilize as soon as possible.

Pay attention to the temperature not lower than 10 ℃, otherwise it is easy to cause frostbite.

2. If the situation is very serious and the roots have softened and blackened, the rotten roots have been caused, and the rotten roots must be cut off immediately, cleaned up and re-changed into the basin.

Reason two

Long-term shade: green pineapple, hanging orchid, rich tree, rich bamboo, ivy. These flowers and plants often raised indoors like semi-shade, there is no great demand for sunshine, but it can not be shaded for a long time.

If there is no sunlight for a long time, the leaves can not carry out photosynthesis, and the nutrients of flowers and plants can not be guaranteed.

Rescue and treatment

Flowers and plants that like light, such as succulent plants, can be put on the windowsill and balcony in winter. Of course, you should pay attention to the temperature not lower than 10 ℃, do not pass through the cold wind, or it is easy to cause frost damage in winter.

Flowers and plants that like semi-shade, such as asparagus, should be placed in a bright and scattered place indoors.

Reason three

The temperature is too low: generally speaking, the temperature at home is not less than 10 ℃, most common domestic plants can survive the winter safely, but if the temperature is too low or accidentally let the flowers and plants blow to the cold wind, the flowers and plants will easily have yellow leaves.

Rescue and treatment

Cut off the yellow leaves, raise the temperature of the living environment of flowers and plants, and keep warm if necessary.

After bagging, when the temperature is high at noon, flowers and plants should open the bag for air. You can also punch a few holes in the bag when bagging to ensure that the breathing of flowers and plants can be carried out normally.

Soil consolidation

Reason one

Hard water watering flowers: tap water contains more soluble calcium and magnesium compounds, long-term use of tap water to water flowers, calcium and magnesium ions precipitate, easy to lead to basin soil consolidation, re-watering water can not ooze.

Rescue and treatment

1, boiling can soften hard water, so usually we 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 consolidated, the soaking pot method can be used to water the flowers, which can not only ensure the watering thoroughly, but also not easy to accumulate water in the basin.

The soaking method allows water to seep in from the permeable hole at the bottom of the basin and can be taken out when the surface of the basin soil is moist. Note that the water in the large pot should not pass the top of the flowerpot.

Reason two

Excessive fertilization: too much fertilization, nitrogen, phosphorus and potassium can not be completely absorbed by flowers and plants, it will be combined with the composition of the soil, causing soil consolidation and hindering the root respiration of flowers and plants.

Rescue and treatment

In this case, the soil needs to be changed. The new soil should be loose and fertile, and it is best to mix some vermiculite or clean river sand to improve the air permeability of the soil.

The blade has holes.

Reason

This situation is generally mechanical injury, mostly insect pests.

Rescue and treatment

1. If there are not many bugs, you can consider catching them by hand to avoid using medicine to burn flowers and plants.

Moss grows on the side of the pottery basin

(author: Huangguo Source: the House of Red Pottery Basin)

Reason

This situation is generally caused by improper watering, or the drainage hole is blocked, resulting in the basin soil is too wet and the flowerpot grows moss.

Of course, if the weather is too humid and the air is humid, pottery pots may also grow moss. Flower friends can see if they belong to this situation.

Rescue and treatment

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 soil of flowers and plants in a cool place to dry, and wait for the soil to become slightly moist and return to the basin.
