Phalaenopsis has strict requirements for soil quality, mainly reflected in the following aspects: 1. Rich in organic matter
Phalaenopsis prefers to grow in soil rich in organic matter. Organic matter can provide sufficient nutrients for the healthy growth and flowering of Phalaenopsis orchids. When planting Phalaenopsis, it is possible to add organic rich materials such as decomposed compost, leaf rot soil, or peat soil to the soil. 2. Good drainage
The root system of Phalaenopsis is sensitive and not tolerant to waterlogging. Choosing soil with good drainage is crucial. This can prevent water from accumulating in the soil and prevent root rot. To improve soil drainage, appropriate amounts of loose substances such as perlite and vermiculite can be added to the soil. 3. Good breathability
The root system of Phalaenopsis requires sufficient oxygen for respiration, therefore the soil must have good air permeability. Soil with good breathability can promote root development and improve the growth quality of Phalaenopsis. When choosing soil, it is advisable to avoid using soil that is too sticky and heavy, as it may hinder the respiration of roots. 4. Suitable acidity and alkalinity
Phalaenopsis also has certain requirements for soil acidity and alkalinity. Generally speaking, it is suitable for growth in neutral or slightly acidic soils with pH values of 6, 0-7, and 0. Both acidic and alkaline soils may have adverse effects on the growth of Phalaenopsis. 5. Specific soil medium selection
Moss soil: Moss soil is one of the commonly used soil media in the cultivation of Phalaenopsis. It has good water retention and permeability, and can provide stable water and oxygen supply for Phalaenopsis.
Perlite: Perlite is a lightweight, porous mineral that can increase soil permeability and drainage, and prevent root waterlogging.
Vermiculite: Vermiculite also has good water retention and breathability, which can help regulate soil moisture.
Peat soil: Peat soil is rich in organic matter, can provide abundant nutrients, and has good water retention and permeability. 6. Soil mix proportion and adjustment
In order to achieve the best cultivation effect, the above media can be mixed and used in a certain proportion. For example, moss soil, perlite, and vermiculite can be mixed in a certain proportion to form a cultivation soil that is both water retaining and breathable. The specific ratio can be adjusted according to the actual situation and personal preferences. 7. Regularly replace the soil
Regularly changing the soil is also an important step in the maintenance process of Phalaenopsis. This can ensure that the soil always maintains good fertility and breathability, providing favorable conditions for the growth of Phalaenopsis. Generally speaking, when the root system of Phalaenopsis orchid fills the entire pot, it is necessary to change the pot and soil.
The soil requirements of Phalaenopsis mainly include rich organic matter, good drainage, good breathability, and suitable acidity and alkalinity. When selecting soil media, the selection and proportioning can be adjusted according to these requirements. At the same time, regularly changing the soil is also one of the important measures to ensure the healthy growth of Phalaenopsis.
