How to propagate rosemary through cutting
Main content introduction: This article provides detailed information on how to propagate rosemary through cutting and the hydroponic propagation techniques for this green plant.
Pruning branches: For hydroponic rosemary, cut the bottom of the branches at an angle to increase the water absorption area, and also remove the lower leaves to prevent water contamination.
Cleaning containers: The containers used must be cleaned first and then disinfected and soaked.
Controlling water level: The water level for hydroponics should be controlled to 2 cm from the lowest leaves.
Regularly changing water: Change the water frequently in the early stage of hydroponics, and replace it when the water quality is contaminated.
Growth environment: Keep it in a well-lit and ventilated area, and it must be shaded at noon.
One, pruning branches
When propagating rosemary hydroponically, it is necessary to prune the branches first, as direct hydroponics makes it difficult for the branches to absorb water and nutrients, which can affect growth. Prepare disinfected tools, cut the bottom of the rosemary branches at an angle to increase the water absorption area, and also remove the lower leaves to prevent them from rotting and contaminating the pruned branches. Removing the leaves also reduces nutrient and water loss, which is beneficial for the growth of hydroponically cultivated rosemary.
Two, cleaning containers
It is best to choose a transparent container for hydroponic rosemary, as it not only allows for easy observation of growth conditions but also provides better light transmission, promoting photosynthesis and growth. The container must be cleaned and disinfected with a disinfectant solution before use, soaked in a potassium permanganate solution for 20 minutes to avoid the presence of bacteria.
Three, controlling water level
When growing rosemary hydroponically, it is also important to control the water level. Too much water can affect the branches' breathing. The water level should be 2 cm from the lowest leaves. It is best to use purified water, and if tap water is used, it must be exposed to sunlight in advance to volatilize the chlorine before use. Using water with too much chlorine can easily cause the leaves of hydroponic rosemary to turn yellow or even wither, severely affecting growth and shortening the shelf life.
Four, regularly changing water
It is necessary to change the water regularly during hydroponic rosemary cultivation to ensure clean and hygienic water. During the early stages of hydroponics, water should be changed every two to three days to keep it clean. After a period of hydroponics, when the branches have adapted, the frequency of water changes can be reduced. Change the water promptly when impurities are seen or the water turns yellow to prevent bacterial growth.
Five, growth environment
During hydroponic rosemary cultivation, it is also important to pay attention to the provided environment, which must be suitable for better growth. It is best to place it in a well-ventilated and sunlit environment to promote rooting. Note that the sunlight at noon is too strong, and shading is necessary. It is best to place the rosemary in a shaded environment to prevent damage from strong sunlight.
