How to choose

  • Feed the soil or the plant. Amendments like alfalfa meal, rock dust, and living soil build long-term soil health, while blended fertilizers give plants a faster nutrient boost.
  • Read the N-P-K. The three numbers show nitrogen, phosphorus, and potassium; higher nitrogen supports leafy growth, higher phosphorus supports roots and blooms.
  • Match to what you grow. Citrus and bloom fertilizers target specific crops, while all-purpose blends suit mixed beds and vegetables.
  • Organic and natural options. Many products here are organic inputs like fish bone meal and glacial rock dust; check the label for certification.
  • Pest and disease care. Horticultural oils and natural repellents help manage common garden problems; follow the application rate on the label.

Frequently asked questions

What do the numbers on fertilizer mean? The three numbers are the N-P-K ratio: nitrogen for leafy growth, phosphorus for roots and flowering, and potassium for overall plant health. Choose a ratio that fits your crop and its stage.

What is the difference between a fertilizer and a soil amendment? A fertilizer feeds plants directly with nutrients, while a soil amendment such as compost, rock dust, or alfalfa meal improves the soil's structure and biology over time. Many gardens use both.

Are these products organic? Many items here are organic inputs such as fish bone meal, glacial rock dust, and living soil blends. Check the individual product page and label for certification and application rates.

When should I apply fertilizer? Most gardens feed in spring as growth begins and through the growing season per the product's schedule. Follow the label rate to avoid over-application.
