Given that many gardening friends have asked about what type of fertilizer to use for roses and what fertilizers can be used, a simple sharing was done a few days ago.
So, faced with such a variety of fertilizers on the market, how should we choose and use them?
Today, let's start with the types of fertilizers and explain step by step until everyone truly understands the functional characteristics of each type of fertilizer and the correct usage methods.
First, let's understand the types of fertilizers that can be used for roses.
Classification of fertilizer types:
Fertilizer types can be simply divided into organic fertilizers and inorganic fertilizers.
In terms of form, they can be divided into liquid fertilizers and solid fertilizers.
According to the duration of effectiveness, chemical fertilizers can be divided into long-acting fertilizers and fast-acting fertilizers.
What is organic fertilizer?
Organic fertilizer is a type of fertilizer containing a large amount of organic matter. It mainly comes from plants or animals, processed from plant and animal waste and plant residues, and is rich in a large amount of organic matter and nutrients such as nitrogen, phosphorus, and potassium.
It not only provides comprehensive nutrition for plants but also has long-lasting effects and is beneficial for improving the soil environment and promoting the reproduction of microorganisms in the soil.
What is inorganic fertilizer?
Inorganic fertilizer is a mineral fertilizer, also known as chemical fertilizer, commonly referred to as fertilizer. It is produced through chemical synthesis and mainly includes nitrogen fertilizer, phosphorus fertilizer, potassium fertilizer, and compound fertilizers of nitrogen, phosphorus, and potassium.
Inorganic fertilizers have a high content of effective ingredients, are mostly soluble in water, and are easily absorbed by plant roots, also known as fast-acting fertilizers.
In the process of raising roses, we often use organic fertilizers, water-soluble fast-acting fertilizers, and slow-release fertilizers, controlled-release fertilizers, and other long-acting fertilizers.
Talking about slow-release fertilizers and controlled-release fertilizers, many gardening friends may not be very familiar with the differences between the two, although both are long-acting inorganic fertilizers, there are many differences between these two types of fertilizers.
What is a slow-release fertilizer?
As the name implies, a slow-release fertilizer is a type of fertilizer with a slow release of fertilizer effect.
What is a controlled-release fertilizer?
A controlled-release fertilizer is a higher form of slow-release fertilizer, produced using film-coating technology to control the release of nutrients to meet the different fertilizer needs of roses at various growth stages.
What is the difference between slow-release fertilizers and controlled-release fertilizers?
Controlled-release fertilizers are more advanced than slow-release fertilizers, with the release of fertilizer effects less affected by temperature, while the release of slow-release fertilizers is greatly affected by temperature.
Because the release of slow-release fertilizers is greatly affected by temperature, it has always been emphasized:
Do not use slow-release fertilizers as a base or top dressing for roses in the summer or approaching summer!
Otherwise, it is very easy for the fertilizer effect to be released in a concentrated manner due to high temperatures, which can lead to fertilizer damage.
Fertilizer damage caused by slow-release fertilizers is irreversible, meaning that once we find that roses are problematic, there is no way to rescue them.
In summary, we can classify common fertilizers as follows:
Water-soluble fertilizers and nutrient solutions: belong to fast-acting inorganic fertilizers. Animal and plant waste: belong to long-acting organic fertilizers. Slow-release fertilizers and controlled-release fertilizers: belong to long-acting inorganic fertilizers.
Knowing the nature and characteristics of each fertilizer will guide us in using them reasonably in the process of raising roses.
So, how exactly should we use each type of fertilizer for roses?
Yesterday, it was mentioned that fast-acting water-soluble fertilizers should be applied with watering, once every 10 days. In fact, fast-acting fertilizers can not only be applied to the roots but also used for foliar spray.
Foliar spray, also known as root exterior top dressing, is a quick-acting and relatively safer method of top dressing than root dressing, especially when roses show deficiency symptoms. Using root exterior top dressing can improve the deficiency symptoms of roses in a short time.
Is this good top dressing method something you also want to learn?
Due to limited space, more specific sharing will be done tomorrow.
