Understanding Houseplant Nutrients
Fertilizers provide essential nutrients that plants need to grow. The three primary nutrients, known as macronutrients, are:
- Nitrogen (N) promotes leafy growth and overall greenery.
- Phosphorus (P) supports strong roots and flower development.
- Potassium (K) enhances plant health and disease resistance.
Besides these, micronutrients like calcium, magnesium, and iron also play a vital role in plant development.
