Fertilizing is one of the most important steps in maintaining healthy, vibrant plants. Whether you’re caring for indoor greenery or growing a lush outdoor garden, the right fertilizer can make all the difference. But with so many options available, how do you choose the best one?

Why Fertilizers Are Important

Plants rely on three key nutrients:

• Nitrogen (N) for leafy growth.
• Phosphorus (P) for strong roots and blooms.
• Potassium (K) for overall plant health and resilience.

While soil contains some nutrients, regular fertilizing ensures your plants get what they need to thrive.
