Will the rotten roots of yellow leaves blossom? It only takes 2 steps to solve the problem, and it doesn't matter to raise it for 10 years!

Common disease

In the process of maintenance, the most common problems can be summarized as the following two kinds: the part above the soil and the part under the soil.

The earth part

General soil parts are easy to appear: no long leaves, yellow leaves, dead leaves, deciduous leaves, long spots on leaves, perforation, no flowering, less flowering, burning flowers, short florescence, diseases and insect pests and so on.

Subsoil part

The following common problems in the soil are too dry, too wet, not enough fertility, airtight, growing bugs, over-acid and over-alkali, and so on.

Once you understand the disease, you need to find out what the cause is in order to prescribe the right medicine. Next Huahua will tell you how to check the cause of the disease!

Etiological examination: underground problems

When the cause cannot be determined, follow the principle of "going down first and then going up", that is, check the basin soil first and avoid blindly watering and fertilizing, which will make the problem more serious.

When the situation is not serious

1. Dry and wet state: you can insert your hand into the 2cm depth of the soil. If you feel slightly moist and the soil layer is soft, you do not need watering for the time being. If it is too dry, you can water it at the right time according to the preference of the flowers.

2. Soil fertility: judge fertility by color. If the color is too light and the soil layer is hardened, the fertility must be insufficient. Rotten liquid fertilizer and water can be used to improve fertility and loosen the soil at the right time.

3, pH: the simplest method of pH detection is to use ph test paper, over-alkali can be poured with some diluted vinegar or ferrous sulfate to improve!

When the situation is serious

When there is no big problem with the soil medium, you can dig up the soil layer with a small spade to check for root problems and root rot, then you need to dig out the plant and carry out "surgical removal."

1. Gently shake off the peeled root of the flower, then rinse it off with clean water.

2. Cut off the rotten root system from the bottom up with scissors, and then apply plant ash or fine furnace ash to the wound.

3. Soak the treated root in 0.1% potassium permanganate solution or diluted carbendazim solution for about 1 hour, then leave it in a cool place to dry for about 1 day.

4. Change the soil to pot again after the root system is treated.

Etiological examination: soil problems

There are three factors above the soil, light, air humidity and diseases and insect pests.

Light judgment

1. In general, when the leaves turn yellow and droop, the flower branches are thin and weak, the flower buds turn yellow and fall off, and the flowers are too small or do not bloom, it can be judged that the light is too little.

2. Flowers with small and dense leaves are mostly semi-negative, such as camellia, asparagus, Tianmen winter, etc., which need to be maintained in indoor astigmatism; flowers with large and sparse branches and leaves are positive flowers, such as triangular plum, jasmine, dahlia, a bunch of red, etc., should be placed outdoors or south windowsill to increase illumination.

Humidity judgment

Air humidity is a problem that many flower lovers are easy to ignore. Why do the flowers bought in the flower market wilt as soon as they are taken home? it is because the humidity in the flower market is much higher!

1. If the color of the leaf is yellowish, the edge is dry, the luster is lost, or the color of the flower becomes lighter and the florescence is shortened, the air humidity is too small, then spray the leaves and branches, or cover the plant with a plastic bag to increase the humidity.

2. In the process of indoor maintenance in spring and summer, if there are moldy petals, fallen flowers, or the spread of diseases and insect pests, branches and leaves grow, indicating that the air humidity is too high, it is necessary to open the window in time for ventilation!

3. Generally, indoor humidity can be maintained at 60% to 70%. More than 70% is not good for household appliances and furniture; when it is less than 60%, water can be sprayed on the ground to increase humidity. It is suggested that flower friends hang dry and wet bulb hygrometers indoors for convenience and ease of use.

Pest control

General flower diseases and insect pests are mainly divided into three categories: fungal type, bacterial type, viral type.

1. Fungal type: the environment is too wet and easy to be infected with fungi, which is mainly characterized by mildew and powder growing in flowers and leaves, decay and discoloration, necrosis, wilting, root ulcers, etc.

2. Bacterial type: there are not many bacterial infections, such as water stains, oil stains and bacterial pus on flowers and leaves.

3. Viral type: flowers in high temperature and hot environment in summer are vulnerable to insect pests, thus infected with virus, such as long spots, ring lines, deformed dwarfing and so on.

When flower friends find that plants are infected with diseases and insect pests, they should immediately carry out "amputation" to cut off diseased branches and dead branches to prevent infection to other parts.

The examination of the disease is actually very simple.
