Therefore, special attention should be paid to controlling the pH value of the soil in daily management, otherwise, the alkaline soil will affect the absorption of water and nutrients by the roots, leading to poor growth and no blooming.
Temperature Reasons: The optimal growing temperature for Phalaenopsis orchids is between 23 to 28 degrees Celsius, only by maintaining this temperature can they bloom well.
Light Reasons: Insufficient light will result in abnormal growth of Phalaenopsis orchids, often with more leaf buds than flower buds.
Ventilation Reasons: Placing Phalaenopsis orchids in places with poor ventilation can easily cause the plants to get sick, especially during the blooming period, the top of the flower stem is prone to withering, leading to yellowing of the flower buds, affecting blooming, and even the already bloomed flowers can easily wilt prematurely.
Fertilization Reasons: Over-fertilization can easily cause the flower buds of Phalaenopsis orchids to fall early. Nitrogen fertilizer can be applied during the vegetative growth period, but it should be stopped during the reproductive growth period, and more phosphorus and potassium fertilizers should be applied to promote bud formation and blooming.
Watering Reasons: Insufficient watering can also easily cause leaf yellowing, affecting flower bud differentiation and blooming.
