Phalaenopsis is a standout among household flowers. To ensure that Phalaenopsis grows robustly and has a long flowering period, proper fertilization is of great significance. So, how can we determine whether Phalaenopsis needs fertilization? And how should we fertilize it correctly to extend its flowering period?
How to Determine Whether Phalaenopsis Needs Fertilization:
Observe the Leaf Growth Status: The leaves of Phalaenopsis directly reflect its nutritional status. When the leaves are bright green, glossy, and growing vigorously, it indicates that the plant has sufficient nutrients and does not need fertilization for the time being. On the contrary, if the leaves turn yellow, become thinner, or grow slowly, it may be due to a lack of nutrients, and fertilization should be considered.
Pay Attention to the Growth Stage: Phalaenopsis has different nutritional requirements at different growth stages. During the peak growth season (from spring to autumn), the plant has a high demand for nutrients, which is the best time for fertilization. In the winter dormancy period, Phalaenopsis grows slowly and has a reduced demand for fertilizers, so the frequency and amount of fertilization should be decreased.
Check the Root Status: The roots of a healthy Phalaenopsis should be white or light yellow and covered with fine root hairs. If you find that the roots are black, rotten, or not growing well, it may be caused by excessive fertilization or improper fertilizers. At this time, you should stop fertilizing and adjust the fertilization plan.
How to Fertilize Correctly to Extend the Flowering Period:
Select Appropriate Fertilizers:
Special Orchid Fertilizers: They contain an appropriate amount of nitrogen, phosphorus, potassium, and trace elements, which are suitable for the growth needs of Phalaenopsis.
Liquid Fertilizers: They are easy to use and are easily absorbed by plants, making them suitable for quickly supplementing nutrients.
Slow-release Fertilizers: They have a slow release rate and can provide long-lasting nutrient support for the plant, which is suitable for growers who do not want to fertilize frequently.
Master the Timing and Frequency of Fertilization:
Peak Growth Season: Apply a thin fertilizer once a week or every two weeks, and the concentration should be low to avoid burning the roots.
Flowering Period: During the period from the emergence of the flower spike to the actual blooming of Phalaenopsis, a large amount of nutrients need to be stored. Fertilization should be continued, but the concentration should be appropriately reduced until the flower stamen reaches the size of a thumb, and then stop fertilizing.
Dormancy Period: Reduce the frequency and amount of fertilization, or even stop fertilizing to avoid affecting the health of the plant.
Pay Attention to Fertilization Methods and Techniques:
Apply Thin Fertilizers Frequently: Avoid applying too much fertilizer at one time, which may cause root burns.
Avoid Fertilizing Directly on the Roots: It is best to mix the fertilizer with water and water it evenly to avoid concentrating the fertilizer in one place.
Rinse with Water After Fertilization: After fertilization, rinse the orchid pot and the orchid plant with a large amount of water to prevent the residue of inorganic salts from harming the roots.
Regularly Check the Roots and Leaves: During the fertilization period, regularly check the roots and leaves of Phalaenopsis. If any abnormal situation occurs, adjust the fertilization plan in a timely manner.
Auxiliary Measures:
Water Reasonably: Water reasonably according to seasonal changes and the needs of the plant, and keep the soil moist but not overly wet.
Provide Sufficient Light: Provide sufficient light but avoid direct sunlight for a long time, which is helpful for the growth and blooming of Phalaenopsis.
Prune Appropriately: Remove diseased and pest-infected leaves, yellowed leaves, and overly dense branches and leaves in a timely manner to keep the plant well-ventilated and well-lit.
In conclusion, by scientifically determining whether Phalaenopsis needs fertilization and properly managing fertilization, we can effectively extend the flowering period of Phalaenopsis and make it bloom more durably and beautifully at home.
