Macronutrients: These are nutrients that plants require in relatively large amounts. They include:

Nitrogen (N): Used for plant growth and development, especially for leafy green growth.
Phosphorus (P): Important for root development, flower and fruit production, and seed development.
Potassium (K): Essential for plant growth and overall health, including stress tolerance and disease resistance.
Calcium (Ca): Important for cell wall development and overall plant structure.
Magnesium (Mg): Essential for chlorophyll production and energy metabolism.
Sulfur (S): Used for protein synthesis and overall plant growth.

Micronutrients: These are nutrients that plants require in smaller amounts, but are still essential for plant growth and development. They include:

Iron (Fe): Used for chlorophyll production and overall plant growth.
Manganese (Mn): Important for photosynthesis and overall plant growth.
Zinc (Zn): Essential for enzyme activity and overall plant growth.
Copper (Cu): Used for chlorophyll production and overall plant growth.
Boron (B): Important for cell wall development and overall plant structure.
Molybdenum (Mo): Essential for nitrogen fixation and overall plant growth.
Chlorine (Cl): Used in photosynthesis and overall plant growth.

"Choosing the right fertilizer for your plants, as well as the dosage and frequency of application is essential to ensure healthy growth and optimal yields. The key to selecting the right fertilizer is understanding the unique nutrient needs of your plants and identifying any deficiencies or imbalances. For example, during the vegetative growth phase, plants require more nitrogen to support leaf and stem growth, while during the flowering and fruiting phase, plants require more phosphorus and potassium to promote flowering and fruit development. If you are unsure about the nutrient needs of your plants, you may use ready-made fertilizers with a balanced nutrient mix, like Green Diet that is a holistic nutrient solution for all types of plants or Flora Diet that is a unique nutrient solution specially made for flowering plants. This can simplify the process and ensure that your plants receive all the necessary nutrients in the correct proportions."

Plant nutrients are the essential building blocks for plant growth and development, while Growth Promoters, on the other hand, can be compared to vitamins for humans. Growth Promoters such Sea Secret and Humic Secret regulate various aspects of plant growth, such as cell division and elongation, root growth, flowering, and fruit development, increase plant vigour and enhance photosynthesis.

It depends on the specific needs of the plant and the goals of the fertilisation program. Slow Release Granules can provide a sustained source of nutrients to plants, as the nutrients are taken up by the roots and stored in the plant tissues over a period of time. However, liquid fertilisers can be applied to the plant foliage, particularly for addressing nutrient deficiencies and providing a quick boost of nutrients. Foliar fertilisation can provide a rapid and targeted supply of nutrients to plants, as the nutrients are absorbed directly through the leaves and transported to the areas of the plant that need them most. However, they need to be applied more frequently than Slow Release Granules.

Yes, it is possible to over-fertilize plants, and it can actually be harmful to them. Fertilizer is intended to provide plants with the necessary nutrients they need to grow and thrive, but too much fertilizer can lead to a build-up of salts in the soil, which can harm the plant's roots and prevent them from absorbing water and nutrients.
