What is the physiological disease of flowers? What shall I do?

Flowers in the growth process, due to the lack of some nutrients, or due to soil over-acid, over-alkali, or temperature and humidity is too high, too low, light is too strong, too weak, and pollution caused by diseases, called physiological diseases.

The common physiological diseases of flowers are:

The main results are as follows: (1) the growth of new leaves and basal stems are too slow or even not long, the lower leaves of the plant are drooping and the leaves are pale, which is caused by the lack of fertilizer. The symptoms can be improved after adding nitrogen fertilizer for several times.

(2) the branches are slender, the internodes are elongated, the leaves are thin, large and thin, and the color is light, which is caused by the lack of light, so the sunshine time should be increased gradually.

(3) the lower leaves of the plant are curly and the new leaves do not grow big, which is due to the strong light, so the sun is shaded properly or moved to the place where the light is weak.

(4) the leaf is weak, the leaf tip is withered, and the lower leaf falls off, which is caused by lack of water. Check whether the basin soil is hardened, whether the root is bitten by pests and affect water absorption, and deal with the symptoms. At the same time, pay attention to watering thoroughly each time to stop waist water.

(5) the branches and leaves are wilting, the color is dark and even mildew gradually, which is caused by too much water in the basin and lack of air in the roots. Check whether the water hole at the bottom of the basin is blocked and control the watering times. Ensure that the drainage hole is unobstructed.

(6) the leaf edge wrinkles, withered tips, or even the whole leaf withered, because the air is too dry, or the temperature is too high, you should often spray water to the leaves, and put the flowerpot into a water-bearing sand trough or often sprinkle some water on the ground around the flowerpot to humidify and cool down.

(7) there are yellowish-brown patches on the leaves facing the sun. Gradually talking to the outside, there is a white bubble in the middle, which is caused by sunburn and should be shaded and protected from the sun.

(8) the branches and leaves grow abruptly, the pregnant buds are few, and the tile basin L appears moss, which is caused by too much nitrogen fertilizer, so the times of fertilization should be reduced, and only phosphorus and potassium fertilizer should be applied without nitrogen fertilizer during the budding period.

(9) poor plant growth, leaf shrinkage, decay, shedding, white frost along the mouth of the flowerpot and the topsoil after drying, which is too alkaline. Remove the frosty topsoil, first dissolve the salt in the soil with a small amount of water, and rinse with a large amount of water after half an hour. Rinse salt, or neutralize alkali with vinegar water (1 bowl of water plus 1 tablespoon of vinegar).

(10) the roots in the basin must be exposed, and the roots at the bottom of the basin must be drilled out, and wilting occurs soon after watering. The new leaves are small and few, or the drop of flowers and fruits may be the reason why the pots have not been changed for a long time or the pots are small.
