It is no secret that just like humans, plants need good nutrition to remain healthy. Good gardeners are aware of which fertilizers to use and how much to use. There occur changes in appearance and discoloration, which are indicators that the plant lacks nutrients. It is not rocket science figuring this out. You’ll need to know the following to ensure good plant growth.
- The right way to feed a plant during each of its stages
- Information on plant-specific nutrients needed
- Common feeding mistakes to avoid
How important are plant nutrients?
The three categories are
- Macronutrients: Nitrogen, Phosphorous, Potassium classified as macronutrients are essential for health and growth of the plant.
- Secondary nutrients: Calcium, Magnesium, Sulphur are less essential when compared to macronutrients.
- Micro nutrients: Iron, Borone, Chlorine, Manganese, Zinc, Copper, Molybdenum
Significance of Nitrogen (N), Phosphorous (P) and Potassium (K):
Also referred as N-P-K, if a plant lacks the required amount of these nutrients, it dies. Plant foods you purchase contain 3 numbers in the label which signifies the ratio of these nutrients present in it. The Grow Depot is your one-stop destination for all your gardening needs. Their knowledgeable team is more than happy to help you out with your queries.
What’s with the NPK ratio?
A plant needs right amount of above nutrients. The two main stages of development of a plant are vegetative stage and flowering stage. Vegetative stage requires high nitrogen, medium phosphorous and high potassium while flowering stage requires low nitrogen, medium phosphorous and high potassium content.
How often should I feed my plants?
It is determined based on the nutrients you are using and the type of growing medium.
- Soil growers: Plants that are grown in nutritious soil and under good light conditions don’t need much feeding. You’ll only have to water it at regular intervals.
- Soilless medium: When growing a plant in sphagnum-based or peat medium, more feeding is required. When the top part of the medium is dry, it is time to water it.
- Coco coir: More feeding (with coco-specific nutrients) with ample runoff is required.
- Hydroponics: Since the plant roots are constantly in contact with water, it gets ample nutrients that way.
If the plant is looking pale green, it needs more water. Ensure you don’t end up overfeeding your plant either. Your plant could be prone to nutrient burn if it has too many nutrients while nutrient lock would happen when a plant isn’t able to absorb the nutrients. The pH level must also be right to aid growth.
