Activated carbon for plants
Activated carbon for plants
Today, I’d like to share information about activated carbon and its uses in plant cultivation. Activated carbon is one of those magical substances that can help our beloved houseplants. When it comes to adsorption, it’s a reliable tool for every gardening enthusiast. In this article, we’ll explore the different ways activated carbon can be used for plant cultivation, its benefits, and how to use it effectively to ensure optimal growth and health for our plants. Want to discover the secrets of growing plants with activated carbon? Read on.
HOW IS ACTIVATED CARBON MADE - ALSO USED IN PLANT CULTIVATION?
Activated carbon is primarily made from organic materials such as wood, peat, fossilized coal, and nutshells. It is called “activated” due to its ability to adsorb, or attract and retain molecules of gases, liquids, or pollutants on its surface. The activation process that activated carbon undergoes creates a porous structure with a large specific surface area. This gives it the ability to “actively” absorb and retain substances such as toxins, heavy metals, and organic pollutants.
There are two types of activation processes:
Physical activation – this process involves subjecting organic material to high temperature in the presence of a limited amount of oxygen.
Chemical activation – in this process, organic material is treated with chemicals such as phosphoric acid or potassium hydroxide.
After such processes, activated carbon becomes an effective tool for purifying water and air, and for use in various filtration processes. Activated carbon strongly binds toxins and fungi in plant cultivation.
WHAT ARE THE WAYS OF USING ACTIVATED CARBON?
Depending on its purpose and requirements, activated carbon is used in various forms:
Powder – is one of the most popular forms of activated carbon. It can be easily added to various substances or dissolved in water for use in various filtration and purification processes. It can be added to plant substrates and is often used when rooting cuttings in water.
Granules – activated carbon is also available in the form of granules of various grain sizes, which allows it to be used in water filters, drainage systems or as an element of substrate mixtures for plant cultivation.
Pills – Some activated carbon products are available in tablet or capsule form, making them easier to dose and use in many applications, such as drinking water purification or as a dietary supplement.
WHY IS IT WORTH USING ACTIVATED CARBON IN PLANT CULTIVATION?
Activated carbon is worth using for plants due to its beneficial properties and positive impact on flowers. Activated carbon acts as an effective adsorbent, removing harmful substances from the soil, such as toxins, excess mineral salts, and organic pollutants. This improves soil quality, promoting healthy plant growth and development. Furthermore, activated carbon helps maintain optimal soil moisture levels by regulating water retention, which is especially important for potted plants. Its use also helps prevent fungal diseases and the excessive growth of pathogens in the soil. Therefore, activated carbon for plants is essential for cultivation, as it supports plant health and development at every stage of growth.
HOW TO USE ACTIVATED CARBON FOR PLANTS?
When adding activated carbon to the substrate of potted plants:
– for plants requiring a well-permeable substrate, such as cacti or succulents, it is recommended to add activated carbon in a proportion of approximately 10-20% of the substrate volume,
– for other potted plants that do not require a particularly permeable substrate, smaller amounts of activated carbon can be added, for example about 5-10% of the substrate volume.
Remember that adding too much activated carbon can lead to excessive leaching of nutrients from the substrate, so it’s recommended to exercise moderation and adjust the proportions to the specific growing conditions. Activated carbon in the substrate has a shelf life of two to four years.
During the process of rooting plants in water, it’s worth adding a little powdered activated carbon to the container every time you change the water—ideally every few days. Simply gently mix the activated carbon with the water to provide a healthy environment for the rooting cutting. This simple method also works for rooting plants in perlite or expanded clay.
Activated carbon is an invaluable tool for any plant enthusiast. Its versatile uses, from improving soil structure to removing harmful substances from water during rooting, make caring for plants easier, and allow our seedlings to thrive in a healthy and clean environment, resulting in beautiful appearance and lush growth. I encourage you to experiment with its uses and discover the further benefits it can bring to your plant growing.
