Due to the climate difference between the north and the south, the soil required for growing orchids is also different. In the south, you should choose soil with good drainage to prevent the environment from being too humid to breed bacteria. It can be prepared with pine bark, fairy soil and plant gold stone, the ratio is about 2:1:1. In the north, you should choose soil with stronger water retention to provide sufficient moisture for its growth. It can be prepared from leaf humus soil, peat soil and sand soil, and mixed in a ratio of 6:3:1.

1. Soil conditions
Usually the substrate for cultivating orchids is called plant material, and plant materials can be divided into soft and hard. Depending on the region and climate, the choice of planting materials is also different. Soft plant materials are mainly humus soil, perlite, and peat soil. This type of plant material is highly nutritious and has strong water retention capacity. However, if the amount of water is not controlled well, roots may rot easily. Hard planting materials are mainly pine bark, coconut shells, peanut shells, etc. This type of planting material has good drainage ability, but fertilizers are also easily lost. Usually, hard planting materials are chosen in hot and rainy areas, while soft planting materials are chosen in dry and cold areas.
2. Pot soil preparation
1. Soft planting materials: Soft planting materials mainly include leaf humus soil, perlite, peat soil, etc. When preparing, humus soil is the main ingredient, while peat soil and sand are added. The ratio of the three is about 6:3:1. After thorough mixing, you can add a little organic fertilizer as a base fertilizer to supplement nutrients for orchids.
2. Hard planting materials: Hard planting materials mainly include pine bark, fairy soil, gold planting stone, orchid stone, etc. Among them, pine bark accounts for a relatively high proportion, usually between 40% and 60%, and fairy soil and plant gold stone can be added in equal amounts. If it is a weak seedling, you can use less bark and more fairy soil and planting stones.
3. Precautions
1 2. Selection of planting materials: The climate in the south is relatively humid and there is more rain. It is advisable to choose hard planting materials with better drainage. The north is drier and colder in winter, so you can choose soft planting materials that retain water and heat.
2. Differences in watering: Soft planting materials have strong drainage, so watering should be more frequent, usually once every two days. Hard planting material has good water retention capacity, so watering should not be too frequent, otherwise it will easily flood the roots. Generally, once every 5 days is enough.
