How long does it take for orchids to fertilize?

The best fertilization time of orchids

The key period of fertilization and watering of orchids refers to the rainy season, the arrival of summer solstice and the end of August, so it only takes March (June, July and August) to cultivate orchids. If your orchid can survive this critical period safely and healthily, it will bring you a good mood for one year, which also means the success of orchid cultivation this year.

1, the time of fertilization of orchids. First of all, in the growing period, newly germinated or cultivated orchids need a lot of fertilizer when they germinate and grow new branches and leaves. Furthermore, in the onset period, orchids will suffer from certain diseases due to the lack of certain nutrients, such as yellowing of leaves, and fertilization should be carried out according to the situation at this time.

2. The difference between organic fertilizer and inorganic fertilizer. Orchid fertilization is mainly based on organic fertilizer, supplemented by inorganic fertilizer. Organic fertilizer is mainly human and animal manure. As a diluted common organic fertilizer, the advantage of organic fertilizer is balanced nutrition, while inorganic fertilizer is often called chemical fertilizer, with single nutrition and stronger pertinence.

3. Important fertilizer components. Nitrogen, phosphorus and potassium are the main components needed by orchids, and the main function of nitrogen fertilizer is to promote the growth of stems and leaves and make them flourish. When orchids lack nitrogen fertilizer, the main performance is that the leaves are yellow and even the stems are yellow. The main function of phosphate fertilizer is to promote the growth of roots and new buds. The role of potassium fertilizer is to make plants grow healthily and enhance the disease resistance of orchids.

4. targeted fertilizers. Germination accelerating fertilizer to promote the growth of new buds is generally used in spring. Promote root fertilizer and root growth and development. Promote growth and fertilization, promote plant growth and make leaves grow big and green.

5. In addition, organic fertilizer must be decomposed, and human and animal feces and urine cannot be used directly. Page fertilization should not be carried out in the morning, but in the evening or in a dark place.

Fertilize orchids, but not in the following situations:

First, it is not suitable for fertilization in early spring: orchids that have just come out indoors have just gradually recovered from dormancy and resumed their growth period. At this time, the temperature is low and the activity is not very strong. If fertilization is applied at this time, it will remain in the roots of orchids because the plants cannot absorb it, causing great fertilizer damage. The best time for fertilization is from the vernal equinox.

Second, the high temperature in midsummer is not suitable for fertilization: the general temperature is above 35℃. At this time, orchid plants may be dormant or semi-dormant, vegetative growth is extremely slow, root activity is very weak, and growth has dropped to extremely weak. If fertilization is applied at this time, it will be like "adding insult to injury", and orchid plants can't absorb it at all, which is easy to cause fertilizer damage. If there is more fertilizer in summer and the leaves grow vigorously in autumn, it will also lead to bad flowers in the next year.

Third, it is not suitable for fertilization in winter: in winter, the weather is cold, the temperature is very low, the plants have entered the dormant period, and the flower buds have also entered the vernalization period. The nutritional growth gradually slows down with the dormant period, so fertilization is generally not applied in winter.

4. Not suitable for fertilization at noon: No matter what season, it is not suitable for fertilization at noon, and it is most suitable for fertilization in the morning and evening, because the temperature is the highest at noon in any season, and high-temperature fertilization is very likely to hurt the roots of seedlings.

5. Cymbidium hybridum should not be fertilized when it first enters the pot: Cymbidium hybridum should not be fertilized when it first enters the pot, because the pot soil is too fat, and Cymbidium hybridum plants often cannot survive. Moreover, due to the twists and turns of Lanmiao, the body is in a state of inhibition, the resistance is weak, the roots have not healed, and it is easy to be infected with the virus.

When cyanobacteria are gradually produced, hyphae are densely covered, and an appropriate number of new roots are formed, cyanobacteria will completely return to normal, and after the resistance is enhanced, they can be "thinly fertilized and frequently applied".

Six, orchid plants are not strong, can not be fertilized: if the orchid plants develop abnormally, new buds can not be drawn, orchid leaves are gray-green, dull, and drooping sharply, which may be that the root system is rotten and dying. At this time, you must not fertilize, but only spray foliar fertilizer to supplement nutrition, but not too much. If you still can't restore growth, you can only plough, change soil, trim and maintain, and you can expect to restore growth.

Seven, the new buds are not suitable for fertilization: when the leaves of the orchid seedlings in the upper pot are taken out, it shows that the orchid has taken shape initially, and the new roots are gradually growing and begin to need nutrients. However, at this time, the new roots have not yet grown vigorously, and the roots are few and short, and their functions are weak. Therefore, only when the new shoots grow to a height of about 15cm can we apply less thin fertilizer. If too much fertilizer is applied, the roots of orchids will be damaged.

Eight, flower bud growth is not full and not suitable for fertilization: orchid plants in early autumn, the longer the new roots, the more they begin to sprout flower buds. If the germinated flower buds are not full, or even grotesque, it means that the root system function is not good, and it can only barely grow and grow, which cannot meet the nutritional growth. This orchid must not be fertilized, only a small amount of foliar fertilizer can be sprayed, and it should not be too diligent and excessive. Otherwise, the loss will outweigh the gain.
