What if the orchids are black and fall off?

Differentiation time of orchids in mature stage

It takes about one year for flower bud differentiation of orchids in mature stage. Different orchids are cultivated with different nutrients and buds are unearthed.

The length of florescence is different successively. After being unearthed, such as Hanlan, Cymbidium, Cymbidium and Cymbidium. This process will take about half a year. Four season orchid, Xia Han orchid and so on from the bud unearthed to flowering, it only takes about a month, the time is relatively short.

Prevention and control of orchid shedding during vernalization

Regardless of whether there is vernalization or not, we should pay attention to the management of water, fertilizer and light. There are many causes of orchid shedding and death, and most of them are caused by large amount of fertilizer, too much watering and lack of ventilation. When the flower bud differentiation, there is no need to fertilize, just topdressing, so at this time its nutrition is sufficient, we need to pay attention to the amount of fertilizer.

Attention should be paid to the management of fertilizer and water during flowering so as to promote the growth and expansion of flower buds. And the environmental temperature during vernalization is generally high, which requires frequent sterilization to ensure the normal growth of orchids. When the bud of the orchid is unearthed, we should pay attention to the problems of fertilization, watering and lighting, and be careful to prevent the orchid from falling off.

Pay attention to the fat and water of orchids during pregnancy.

Orchids in the bud period, autumn and winter, need to add fertilizer, so that the bud to maintain expansion and growth, adequate nutrients. The interval between disinfection and fertilization should be kept at an interval of about 7-10 days, and should not be too frequent or too thick, so as to keep plants in sufficient light, otherwise insufficient photosynthesis will lead to rotting roots.

In addition, we should also pay attention to the control of water and fertilizer before flowering. When the bud is small, you should pay attention to watering to ensure the quality of the flowers. If you do not participate in the orchid exhibition, maintain its natural growth and do not deliberately adjust the daily maintenance of orchids.

Matters needing attention in the growing period of orchids

During the growing period, nitrogen fertilizer should be the main fertilizer, which can promote the growth of plants, improve the disease resistance of orchids and ensure the conditions of flower bud growth. Therefore, whether orchids can blossom normally or not is closely related to the daily management in the early days.
