What is the best soil for growing flowers?
Six soils commonly used in family flower cultivation;

1. Humus soil: Humus soil is a mixture of traditional decomposed soil, which consists of plant matter and various organic wastes (such as kitchen waste). Humus soil is formed by long-term decay and fermentation of tree litter in forest topsoil. Can be used for potted plants.

2. Rotten soil: Folium mould, also known as humus soil, is a nutrient soil formed by microbial decomposition and fermentation of plant branches and leaves in soil. It is also a common soil for planting flowers and trees. Humus soil is widely distributed naturally, easy to collect and simple to pile up. Where conditions permit, you can dig directly into the forest in the mountains and learn from humus that has been weathered for many years, or you can use local materials and make humus at home.

3. Peat soil: Peat soil refers to some low plains and valleys deposited by rivers and lakes. Due to long-term water accumulation and dense aquatic vegetation, a large number of incompletely decomposed plant residues accumulate to form peat layer under anoxic conditions. Peatland can be divided into sphagnum peat and swamp peat, and the main difference between these two kinds of peat lies in the different conditions of peat formation.

5. Mountain mud: Humus soil from mountainous areas with acidic soil. Used for planting acid-loving flowers such as azalea and camellia. Chen Junyu, Liu Shihan and others garden flowers azaleas: "Azaleas are acidic soil plants, and potted plants in Shanghai have been planted with black mountain mud."

6. Plain sand: it is a fine-grained sand with pure texture, low silt content and smooth drainage. It is often used for sowing and cutting propagation of flowers, and is also the main material for preparing culture soil.

Extended data

The preparation method of common culture soil is as follows:

1. humus soil: In autumn, 5 leaves of broad-leaved trees, stems and leaves of herbs, 3 sawdust and 2 horse manure are stacked in layers, and human excrement is poured while stacking, covering the pastoral soil with a thickness of 10cm for fermentation and decay. In the spring of the following year, the rotten leaves are mashed and crushed, and then 4 parts of compost soil, 4 parts of plain sand soil and 2 parts of furnace ash soil are evenly mixed according to the volume ratio, and then stacked for a period of time, kept moist, and turned over for 2-3 times, so that the fertilizer and the soil are fully mixed and can be used.

2. Peat soil: 4 parts of peat soil, 4 parts of plain sand soil and 2 parts of horse manure or compost soil, which are evenly mixed and piled up, kept moist and frequently turned over. When there is no horse manure, you can pour thin human manure. It can be used after full fermentation and decomposition.

3. Natural humus culture soil: According to the humus content and viscosity of forest humus soil, it is mixed with garden soil or river mud and rare human excrement, piled for a period of time, and can be used after full fermentation and decomposition.

As for the stacking time of all kinds of culture soil, for ordinary flowers, it can be used in the same year, and it needs to be used every other year when it is used to grow delicate flowers or as cutting soil. Before use, the culture soil should be sieved into granules with a sieve under wet conditions, and an appropriate amount of insecticidal and bactericidal pesticides should be added for disinfection and sterilization.
