When is it difficult to fertilize orchids?

First, early spring should not be fertilized: just out of the room orchids, but also just gradually recover from dormancy to restore growth period, at this time the temperature is low, activity ability is not too strong, if this time fertilization will be due to the plant can not absorb and remain in the root of the orchid, causing great fertilizer damage. The best time to fertilize is at the vernal equinox.

Second, high temperature in midsummer should not be fertilized: the general temperature of more than 35 ° C, then the orchid plant may be in a dormant or semi-dormant state, nutrient growth is extremely slow, root activity is very weak, growth has dropped to extremely weak, if fertilization at this time, like "worse", the orchid plant basically can not absorb, easy to cause fertilizer damage. If the summer fat words, to autumn leaves grow vigorously, but also will lead to the next year's root and leaf flowering are not good.

Third, winter is not suitable for fertilization: winter weather is cold, the temperature is very low, the plant has entered the dormancy period, and the flower bud has also entered the vernalization stage, and the vegetative growth has gradually slowed down with dormancy, so generally winter is not fertilized.

Fourth, should not be fertilized at noon: no matter what season, should not be fertilized at noon, should choose the most appropriate fertilization in the morning and evening, because noon in any season is the highest temperature, high temperature fertilization is easy to damage the seedling roots.

5, the new orchid just on the pot should not be fertilized: the new orchid just on the pot should not be fertilized, because the pot soil is too fat, orchid plants often can not survive. And because the orchid seedlings after several twists and turns, the body is in a state of inhibition, weak resistance, broken roots have not yet healed, easy to infect the virus.

When the orchid fungus is gradually produced, hyphae are densely distributed, and a proper number of new roots are formed, the orchid plant can be completely restored to normal, and the resistance can be enhanced before "thin fertilizer and frequent application".

6. Orchid plants are not strong and cannot be fertilized: if orchid plants do not develop normally, new buds cannot be drawn out, orchid leaves are gray-green, dull, leaves droop, sharp coke, which may be that roots are decaying and dying. At this time must not fertilize, can only spray some foliar fertilizer, supplement nutrition, but not too much. If still can not restore growth, can only turn over the pot for soil pruning maintenance, is expected to recover growth.

Seven, the new bud does not grow up should not be fertilized: when the orchid seedlings in the upper pot are taken out, it indicates that the orchid bacteria have been initially formed, the new roots are gradually grown, and nutrients are needed, but at this time the new roots are still not vigorous, the roots are few and short, and the function is weak. Therefore, when the new buds grow to about 15 cm high, they can be thin and applied less. The orchid root will be damaged if too much fertilizer is applied.

Eight, flower bud growth is not full should not be fertilized: orchid plants to the early autumn, the more new roots grow, but also began to flower buds. If the flower bud is not full, or even strange shape, this shows that the root function is not good, but can only barely grow, but can not meet the nutritional growth, this orchid must not be fertilized, only a small amount of foliar fertilizer, should not be excessive, otherwise, the loss is not worth it.
