What Fertilizers Are Suitable for Phalaenopsis and Can the Fertilizer Water Be Reused After Feeding
To keep Phalaenopsis beautiful and healthy, proper fertilization is crucial. So, what fertilizer is most suitable for Phalaenopsis? Can the fertilizer water left after feeding be used again next time?
Fertilizing Phalaenopsis needs to be adjusted according to its growth cycle and seasonal changes. The following are the types of fertilizer suitable for different time periods and growth stages:
Year-round general-purpose fertilizer: Phalaenopsis can be fertilized all year round, but the temperature should be kept between 15~28 degrees. When the temperature is below 15 degrees or above 32 degrees, fertilization should be stopped. In terms of fertilizer choice, it is recommended to use a general-purpose compound fertilizer with a nitrogen, phosphorus and potassium ratio of 1:1:1 this kind of fertilizer can provide comprehensive nutritional support for Phalaenopsis.
7 months before: 7 months before, root fertilizer and foliar topdressing can be used alternately. At this time, Phalaenopsis is in its growth period and needs sufficient nutrients to support the growth of its leaves and root system.
8~9 months: after entering 8 months, liquid fertilizer can be applied once every 15 days. And after 9 months, a 0.1% concentration of potassium dihydrogen phosphate solution should be used instead as a foliar fertilizer, to promote flower bud differentiation and flower bud formation.
10 months after: 10 months after, in order to promote further development of flower buds and flowering, phosphorus and potassium fertilizers should be the main focus, and trace fertilizers (such as boron, iron, zinc, etc.) should be appropriately topdressed. These elements help improve the stress resistance and flowering quality of Phalaenopsis.
In addition, in terms of fertilization methods, Phalaenopsis commonly uses methods such as root drenching, foliar spraying, and scattering slow-release fertilizer on the surface of the growing medium. Among them, foliar spraying is highly praised because it is less likely to damage roots, is well absorbed, and takes effect quickly. However, it should be noted that foliar fertilizer should not be sprayed during high summer temperatures, to avoid excessively high humidity leading to pathogen infection and crown rot.
After fertilization, after the fertilizer water is left to stand for a period of time, its nutritional components may change, and may even produce harmful substances. These changes may cause damage to Phalaenopsis.
Causing rot and pest damage: fermented fertilizer water generally has an odor and easily attracts pests and bacteria, thereby causing rot and pest problems. These problems will further affect the growth and development of Phalaenopsis.
Unable to guarantee fertilization effect: reusing fertilizer water cannot guarantee the accuracy and effect of fertilization. Because the concentration and composition of the fertilizer water have already changed, it is difficult to determine its specific effect on Phalaenopsis.
Therefore, in order to ensure the healthy growth and good flowering of Phalaenopsis, it is recommended to use fresh fertilizer and water each time you fertilize. After fertilizing, it is also necessary to use a large amount of water to wash the pot or wash the plant, to prevent residual inorganic salts from the fertilizer from causing damage to the roots.
Choosing fertilizers suitable for Phalaenopsis and correct fertilization methods is the key to ensuring its healthy growth and beautiful flowering. At the same time, also pay attention to avoiding reuse of fertilizer water after fertilization, so as not to cause unnecessary damage to Phalaenopsis.
