How to use soil for planting flowers in flowerpots

The soil is the basic material for cultivating flowers, the sustenance of flower roots, and the source of nutrition, water and air supply. Plant roots absorb nutrients from the soil to feed and thrive themselves.

Soil is composed of minerals, organic matter, water and air. The minerals in the soil are granular and can be divided into sandy soil, clay and loam according to the particle size.

Sand accounts for more than 80% and clay accounts for less than 20%. Sand has the advantages of large pores and smooth drainage. The disadvantage is poor water retention and easy to dry. Therefore, sand is the main material for preparing culture soil. Good air permeability, used as cutting matrix, easy to take root. Due to the low fertilizer content in sandy soil, more organic fertilizer should be applied to flowers planted in this soil to improve the properties of sandy soil. The sandy soil has strong absorption of light and heat, high soil temperature, vigorous growth of flowers and early flowering. Sand can also be placed at the bottom of the basin as a drainage layer.

Clay accounts for more than 60% and sand for less than 40%. The soil is fine and sticky, and the soil surface cracks into blocks during drought. It is very troublesome in cultivation and management, easy to harden and poor drainage. Loosen the soil and drain the waterlogging in time. If handled properly, the flowers can grow well and bloom more. Because the clay has good fertilizer and water retention, it can prevent the loss of water and fertilizer. Flowers grow slowly in this soil and the plants are short and strong. When planting flowers in heavy clay, it is necessary to mix more rotten leaf soil, humus soil or sandy soil to improve the properties. Land turning and winter irrigation shall be carried out in winter to loosen the soil and facilitate farming.

Loam is a soil between sandy soil and clay, and the content of sandy soil and clay accounts for half respectively. Those with more sand are called sandy loam or light loam. Those with more clay are called clayey loam or weighing loam.

In addition to the above three types of flower soil, in order to achieve a certain purpose, several other types of soil can be prepared, such as humus soil, peat soil, rotten leaf soil, rotten grass soil, wooden soil, mountain mud, acid soil, etc.
