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

Article Catalog

Orchids like slightly acidic soil, and the pH value of the soil is preferably between 5.5-6.5, which is conducive to better plant growth. Slightly alkaline soil cannot be used as it is not suitable for orchid growth and may even cause the plant to stop growing. Orchids have higher requirements for soil. In addition to the soil being slightly acidic, the soil also needs to have stronger nutrient content, air permeability, drainage, water retention, etc., so that the plants can grow and bloom better. The soil also needs to be disinfected so that there are no germs in it.

1. What kind of soil do they like?

Orchids like slightly acidic soil. The best pH value of the soil is between 5.5-6.5, which is conducive to better plant growth. Slightly alkaline soil cannot be used as it is not suitable for orchid growth and may cause it to stop growing. Orchids have high requirements for soil. In addition to the soil being slightly acidic, they also have certain requirements for soil air permeability and drainage. The soil must have good air permeability to allow the orchid roots to breathe better. The soil's drainage capacity must be stronger, otherwise it will affect the normal drainage of water. The soil must have sufficient nutrients. Generally, culture soil can be mixed with leaf mold soil, garden soil, etc., which can provide sufficient nutrients for plant growth.

2. What soil to use

1. A mixture of 6 parts leaf humus soil, 2 parts mountain soil and 2 parts red soil can be used as culture soil to provide sufficient nutrients for plant growth.

2. Garden soil and leaf humus soil can be used to prepare culture soil. Mix it according to the ratio of 2 parts field soil, 3 parts garden soil, and 5 parts humus soil. Mixing it evenly can maintain the orchid very strong.

3. It can be prepared by mixing sand and humus soil. It can not only improve the drainage and air permeability of the soil, but also provide sufficient nutrients for the plants. The preparation ratio can be 4 parts sand soil and 7 parts humus soil or a Panax notoginseng ratio.
