Soilless cultivation method of flowers

What is soilless cultivation

Some home gardeners in southern my country often soak the rootless stems of lucky bamboo in a vase. They will take root in about 10 days and grow well. After taking root, there is no need to plant them in potting soil. Some other flower plants, such as bamboo evergreen, can be cultivated and displayed using this method, which is called "hydroponics".

Most people think that soilless cultivation is hydroponic flower cultivation, but this is not the case. Hydroponics is just one method of soilless cultivation. If you want to display plants for viewing, you must first fix the plants so that they can grow independently without falling over. This requires using granular cultivation substrates sold in flower shops or pea stone, perlite, etc. to fix the roots, and then inject water into them for cultivation. Commonly used methods include gravel culture, sand culture, leech culture, asbestos block culture, plastic particle culture, etc., collectively referred to as soilless culture.

Advantages of soilless cultivation

No space restrictions

Today, as urban residences develop towards three-dimensional spaces, soilless cultivation is particularly suitable for growing flowers in small areas such as windowsills, balconies, hallways, and desks. Using soilless cultivation method to grow flowers can prevent the occurrence of underground pests and diseases, and there will be no odor due to fertilizing the potting soil. There is no need to prepare the culture soil, saving the trouble of loosening the soil, weeding and repotting.

Flowers grow stronger

What's more important is that the loss of nutrients in potting soil when planting flowers is as much as 40% - 60%. The nutrient loss of soilless cultivation generally does not exceed 10%. If cultivated properly, the growth of flowers and trees will generally be stronger than that of flowers and trees cultivated in potted soil.

Choice of nutrient solution

When carrying out soilless cultivation in a flower farm, the nutrient solution is prepared according to the different needs of various flowers and trees. The operation is quite complicated and involves many issues, such as the composition of nutrients, the concentration of the nutrient solution, the effectiveness of nutrients, the consumption and supplementation of nutrients, and pH testing, etc. When home gardeners conduct soilless cultivation, they do not have the conditions or the need to prepare the nutrient solution by themselves, so they can just buy ready-made ones!

Replacement of nutrient solution

Nutrient elements in the flower container will gradually oxidize and photochemically change, and the pH balance will become unbalanced, so they should be replaced in time. Indoor flowers should be replaced every 3-4 days. When replacing, the cultivation medium must be thoroughly rinsed with clean water, and then new nutrient solution diluted with water is injected, otherwise the water concentration will become higher and higher.
