What kind of soil is suitable for planting flowers and potted flowering plants
More and more people are growing flowers, and what kind of soil is good for planting flowers is a difficult question. Today I will share with you what kind of soil is good for planting flowers and what kind of soil is good for potted flowers.
What role does soil play in the growth and development of flowers:
Soil is an important medium for cultivating flowers, the material basis on which flowers depend for survival, and the main source of the water, nutrients, air and heat needed for flower growth and development. This is because soil is composed of minerals, organic matter, soil moisture and soil air. Minerals are the basic substances that make up soil and can provide the various nutrient elements flowers need. Organic matter not only supplies nutrients for flower growth, but also plays an important role in improving the physical and chemical properties of soil, soil aggregate structure, water retention, water supply, ventilation and temperature stability. Soil moisture is an indispensable material condition for flower growth. Soil air is the source of oxygen needed for root absorption by flowers and for the life activities of microorganisms, and it is also an important condition for the further weathering of soil minerals and the transformation of organic matter to release nutrients. Scientific experiments have proven that, in soil suitable for plant growth, by volume, minerals account for about 38%, organic matter about 12%, and soil air and soil moisture each account for about 15%-35%. According to some sources, the suitable water content for the growth of general flowering plants is 25% of soil volume, and air also accounts for 25%. Because some people do not understand the above principles, when cultivating potted flowers they do not repot or change the soil for a long time, causing the physical and chemical properties of the soil to deteriorate, poor aeration and water permeability, and a lack of nutrient elements, which leads to poor flower growth, yellowing leaves, few flowers, or even no flowers. Therefore, to grow potted flowers well, attention must be paid to repotting and changing the soil at the right time.
What kind of soil is good for potted flowers:
For potted flowers, because their root systems can only grow within a very small range of soil, the requirements for soil are stricter than for open-ground flowers. On the one hand, nutrients should be as abundant as possible, so that the limited potting soil contains the nutrients needed for flower growth; on the other hand, good physical and chemical properties are required, that is, the structure should be loose, the water-holding capacity should be strong, the pH should be suitable, and the fertilizer retention should be good. For this reason, when growing flowers, you should try to choose a neutral or slightly acidic soil with good aggregate structure, loose and fertile, with good water retention and drainage performance, and rich in humus. This kind of soil is light in weight, has large pores, circulates air well and is rich in nutrients, which is beneficial to flower root development and robust plant growth. If flowers are planted in heavy clay soil with poor aeration and water permeability, or in pure sandy soil that lacks nutrients and has poor water and fertilizer retention, or in alkaline soil, then for the vast majority of flowers it easily causes weak growth and even death. However, the soil conditions mentioned above are not possessed by any natural soil. Therefore, the soil for potted flowers needs to use an artificially prepared culture soil. This culture soil is made by mixing two or more kinds of soil or other medium materials in a certain proportion according to the different growth habits of flowering plants, so as to meet the growth needs of different flowers.
