What are the reasons why Phalaenopsis orchids do not bloom in winter and spring?
Phalaenopsis orchids bloom in winter and spring, but sometimes they do not bloom when cultivated artificially. The reasons are as follows:
Soil reasons: Phalaenopsis orchids prefer acidic soil, with an optimal soil pH value of 4.5 to 5.5. Therefore, special attention should be paid to controlling the soil pH in daily management, otherwise it may lead to poor growth and no blooming.
Temperature reasons: The optimal growth temperature for Phalaenopsis orchids is between 23℃ and 28℃, and they can only bloom well at this temperature. Light reasons: Insufficient light will cause the growth of Phalaenopsis orchids to be abnormal, often with more leaf buds and fewer flower buds.
Ventilation reasons: Poor ventilation can make the plants susceptible to diseases, especially during the blooming period, the top of the flower stem is prone to withering, causing the flower buds to turn yellow and affecting blooming. Even the already open flowers can easily wilt prematurely.
Fertilization reasons: Over-fertilization can easily cause the flower buds of Phalaenopsis orchids to drop early. Nitrogen fertilizer can be applied during the vegetative growth period, but phosphorus and potassium fertilizers should be applied more during the reproductive growth period, with nitrogen fertilizer stopped, to promote bud formation and blooming.
Watering reasons: Insufficient watering can also cause the leaves to turn yellow, ultimately affecting the differentiation of flower buds and blooming.
The above are some tips on why Phalaenopsis orchids do not bloom in winter and spring in the field of green plants and flowers, hoping they can be helpful to you in life!
