When a Phalaenopsis grows a flower spike, people look forward to the moment when it blooms. However, many novice flower growers are often confused about whether the growing medium of Phalaenopsis can be changed after it grows a flower spike and how to fertilize it. Now, let's answer these questions one by one.
Can the growing medium of Phalaenopsis be changed when it has a flower spike? It is not recommended. When Phalaenopsis is in the period of growing a flower spike, it is in a crucial stage of reproductive growth. Changing the growing medium at this time may cause unnecessary stress to it, affecting the normal development of the flower spike and the opening of the flowers. Therefore, to ensure that Phalaenopsis can bloom smoothly, we suggest avoiding changing the growing medium after the flower spike appears.
After Phalaenopsis grows a flower spike, its demand for fertilizers will change in the following aspects:
Choose high - phosphorus and potassium fertilizers:
During the period of growing a flower spike, Phalaenopsis needs more phosphorus and potassium fertilizers to promote flower bud differentiation and bud formation. Thus, we can choose fertilizers such as Flower Bud No. 2 or potassium dihydrogen phosphate, which are high in phosphorus and potassium.
Control the fertilization ratio:
When fertilizing, it is crucial to pay attention to controlling the ratio. Generally, the fertilizer can be diluted to a ratio of 1:3000 to 1:4000 for application. This can provide sufficient nutrients while avoiding harm to the plant.
Follow the principle of applying thin fertilizers frequently:
To avoid damage caused by excessive fertilizers, we should follow the principle of "applying thin fertilizers frequently". That is, use fertilizers with a low concentration and fertilize frequently, so that Phalaenopsis can continuously obtain an appropriate amount of nutrients.
Alternate different fertilizers:
To provide comprehensive nutrition for Phalaenopsis, we can alternate fertilizers such as potassium dihydrogen phosphate and Flower Bud No. 2 during the flower - spike period. This can not only ensure that the plant gets balanced nutrition but also promote its healthy growth.
Pay attention to the fertilization timing:
When the first flower begins to bloom, we should stop using high - phosphorus fertilizers to avoid shortening the flowering period. At this time, we can choose to use balanced fertilizers or appropriately reduce the fertilizer concentration to continue providing necessary nutritional support for Phalaenopsis.
It is not recommended to change the growing medium of Phalaenopsis during the period of growing a flower spike. Instead, its growth needs should be met through reasonable fertilization. We hope these maintenance guidelines can help your Phalaenopsis bloom smoothly and show its most beautiful appearance.
