What is missing from the flowers? What fertilizer should be applied, thank you

The loss of leaves of flowers and plants is not necessarily caused by a lack of fertilizer, but by the unsuitable maintenance method and maintenance environment.

1.Watering, generally in the indoor maintenance of flowers and trees, to see dry and wet watering, the surface of the pot soil is not dry do not water, but watering to water thoroughly, there are leaking gaps must be filled in time. If you water too often, the potting soil will be wet and the root system will rot, resulting in difficult delivery of water and nutrients, and the plant will lose its leaves and die in the worst case.

2.Fertilization, fertilization is based on the principle of frequent application of light fertilizer during the growth period, and thick fertilizer and raw fertilizer can not be applied, otherwise the plant is difficult to absorb, resulting in fertilizer damage, and the light ones fall and the heavy ones die.

3.Light, flower growth needs a suitable environment, in the shade environment, no photosynthesis, the leaves are very prone to the phenomenon of falling leaves, yellow leaves, sun-loving plants must be in a sunny place, like semi-shade must be placed in a semi-shaded or scattered light position.

4.Ventilation, any plant prefers good ventilation, so that it not only grows luxuriantly, but also rarely infects itself with pests and diseases.

5.Pests and diseases, there are leaves falling, may be caused by plant infection with pests and diseases, can be found through observation, general flowers have aphids, scale insects, red spiders, etc., but can be seen with the naked eye; Diseases mainly harm leaves, stems, and roots, but these diseases are mainly caused by unsuitable maintenance environments.

Flowering leaves may be a lack of potassium fertilizer. Potassium fertilizer should be applied appropriately.

Remove the soil from the surface of the pot and replace it with new soil. Water thoroughly to dilute and dilute nutrients in the soil.

The withered flowers can be picked off to make fertilizer, but they must be fully decomposed, otherwise they will cause the crops to burn the roots and seedlings, affecting the growth of crops, and this nutrient element is single, it is recommended to use Fujinmen water-soluble fertilizer, a variety of formulas, to meet the growth needs of crops.

1. The location of symptoms.

If the symptoms first appear on the old leaves, it means that the plant is deficient in nitrogen, phosphorus, potassium, magnesium, zinc, etc.; Symptoms first appear on the new tissues, indicating a lack of calcium, iron, boron, etc. in the plant.

You can judge what kind of fertilizer flowers lack by the leaves, and you must know if you love flowers.

2. Nitrogen deficiency fertilizer.

When nitrogen fertilizer is deficient, the whole plant will be dark dark green, the petiole turns purple, the development is stunted, the old leaves are not spotted but the leaf veins appear yellow, and the leaves are easy to fall off.

3. Potassium deficiency or zinc deficiency.

When potassium or zinc deficiency occurs, yellow, brown, purple and other spots will appear on the old leaves (different from flower to flower), the leaf tips are scorched and curled downward, and the leaves turn yellow from the edge to the center, but the leaf veins are still green, the leaf edge is curled upward or downward, and the leaf gradually withers.

You can judge what kind of fertilizer flowers lack by the leaves, and you must know if you love flowers.

4. Boron deficiency or calcium deficiency.

When boron or calcium are deficient, symptoms begin to appear in new leaves, which can easily lead to terminal bud death.

You can judge what kind of fertilizer flowers lack by the leaves, and you must know if you love flowers.

5. Iron deficiency. When iron is deficient, the young leaves are yellowish-white, and the veins are still green, but the leaf margins will gradually wither over time.

Judge what fertilizer your favorite flower lacks through the above leaves, what fertilizer to apply to it, it will definitely grow very well, so you can judge what fertilizer the flower lacks through the leaves, you must know if you love flowers!

Orchid fertilization can be done by looking at the leaves to know what fertilizer it needs.
