How to see what kind of fat the gentleman orchid lacks? What if the gentleman orchid is short of fat?

If you want to raise the orchid well, you can't do without fertilization, because the orchid needs a variety of nutrients to meet its growth and development. Once there is a lack of certain nutrients in the basin soil, it will be reflected in the orchid plant. Therefore, according to the growth status of Magnolia (leaves) for nutritional diagnosis, so as to determine the type of fertilization.

1. Lack of nitrogen fertilizer

The whole plant of Cymbidium is stunted, the leaves are weak and yellowish, the lower leaves are yellow, the growth stops, and then the dry brown is often related to nitrogen deficiency.

2. Lack of phosphate fertilizer

The flowers are not bright, the flowering is delayed, the leaf sheath is purple-brown, the leaves are dark green, the fruit is small, and the lack of seeds is often related to phosphorus deficiency.

3. Lack of potash fertilizer

The fleshy roots are underdeveloped, the plants are small and weak, the leaves are yellow with necrotic spots, and the flowers are small and unfruitful, which is related to potassium deficiency.

4. Iron deficiency

The new leaves are yellow and white, and chlorosis is often related to iron deficiency; the leaves are curly and yellow, the veins are still green, and the small flowers are related to iron deficiency and magnesium deficiency, and so on.

Therefore, according to the growth status of Cymbidium, it is necessary to adjust the types of fertilization. Cake fertilizer and urea contain more nitrogen, which can promote root and leaf luxuriant. Rice bran, bone meal, fishy water and feather water contain more phosphorus, which can help the development of flowers, fruits and seeds. Plant ash and potassium dihydrogen phosphate fertilizer contain more potassium, which can make yellow leaves green, roots strong, and enhance the ability of cold and drought resistance. For chlorosis, alum fertilizer and water (0.5% ferrous sulfate) can be applied.
