What kind of soil do orchids like? Do they prefer acidic soil or alkaline soil?

1. What kind of soil do you like?

Orchids like slightly acidic soil, and the pH value of the soil should be between 5.5-6.5, which is conducive to better growth of the plants. Do not use slightly alkaline soil, which is not suitable for orchid growth and may stop it from growing. Orchids have high requirements for soil. In addition to the soil being slightly acidic, it also has certain requirements for soil air permeability and drainage. The soil needs to have good air permeability to allow the orchid roots to breathe better. The soil drainage capacity should be stronger, otherwise it will affect the normal discharge of water. The soil must have sufficient nutrients. Generally, the culture soil can be prepared by mixing leaf mold, garden soil, etc., which can provide sufficient nutrients for plant growth.

2. What soil to use

1. You can mix 6 parts of leaf mold, 2 parts of mountain soil, and 2 parts of red soil to make the culture soil to provide sufficient nutrients for plant growth.

2. You can prepare the culture soil with garden soil and leaf mold. Mix 2 parts of field soil, 3 parts of garden soil, and 5 parts of leaf mold. Such a well-mixed mixture can keep the orchid healthy.

3. You can mix sand and leaf mold to improve the drainage and air permeability of the soil, and provide sufficient nutrients for the plants. The preparation ratio can be 4 parts of sand and 7 parts of leaf mold or the ratio of Panax notoginseng.
