Four reasons orchids do not bloom. Once you understand them, you can solve the problem.

People who grow orchids all hope to see their flowers and smell their fragrance. Recently many readers have asked Haoshe Nongfu: the orchid leaves grow very well, but they just will not bloom. Why?Haoshe Nongfu is not an expert, and does not understand most orchids. I can only answer using wild orchids from Huizhou, and hope it helps my friends.

As far as Haoshe Nongfu knows,a plant needs several conditions to bloom: light, water, fertilizer and temperature. Orchids are certainly no exception. Only when these four conditions are suitable will they naturally bloom.Haoshe Nongfu will not recite textbooks; I will just talk about what I actually do (the climate of a rural village in Jixi, Huizhou), and share real examples with friends.

1. Starting every year in November of the solar calendar, increase the light the orchids receive.The shade net used in summer should be taken down at this time, to increase the photosynthesis of the orchid plants, so they can better store energy and prepare for bud formation and blooming.

2. WaterBefore bud formation, you must control water. Too much water easily causes excessive leaf growth, and excessive leaf growth consumes a large amount of energy, making bud formation difficult. Haoshe Nongfu used to grow watermelons in the countryside and knows this is the same as farmers growing watermelons: if the watermelon leaves grow excessively, it is very difficult for them to bloom, and even if they do bloom, fruit set is difficult.

3. FertilizerWhen orchids are on the mountain, fallen leaves cover them every year, and after the fallen leaves rot they become organic fertilizer, which is equivalent to applying a layer of organic fertilizer every year. But after being potted, some orchid growers are afraid of burning the roots and do not dare to fertilize, or they fertilize improperly. For example, applying too much nitrogen fertilizer (urea) can also easily cause failure to bloom. Before bud formation, Haoshe Nongfu applies some phosphorus and potassium fertilizer to the orchids. In agricultural production, phosphorus and potassium fertilizer promotes flowers and fruit, while nitrogen fertilizer promotes leaves. Everyone, remember this well.

4. TemperatureOrchid bud formation needs suitable temperatures, and also a suitable temperature difference. Here, the bud formation period for Cymbidium goeringii is generally between 10°C and 25°C, so a temperature difference of about 15°C should be fairly suitable for Cymbidium goeringii. In books this is also called vernalization. The purpose of vernalization is somewhat similar to water control: both inhibit the growth of orchid leaves and shift energy to bud formation.

If you like it, follow and share it, so more friends can see it.

Master these four points, and you will not have to fear that orchids are hard to bloom. Friends, what do you think? If anything is lacking, please add to it. Many thanks!
