Did you know your plants need three key ingredients to grow strong and healthy?
Light, moisture, and nutrients are all essential for a thriving garden. When even one is missing, your plants won’t perform to their full potential. Calloway’s Premium Plant Foods are here to help! Our customized formulas are expertly crafted to provide the nourishment your plants need for vibrant, vigorous growth all season long.
PLANT FOOD 101
Ever wonder what the numbers on plant food labels mean?
They represent the percentages of nitrogen (N), phosphorus (P), and potassium (K)—three vital nutrients for healthy plant growth. You’ll find these formulas on every container of Calloway’s Premium Plant Foods, available in 4 lb and 16 lb sizes to suit your garden’s needs.
What each nutrient does:
- Nitrogen (N) supports green leaves, healthy roots, and strong stems.
- Phosphorus (P) promotes strong roots, blooms, and fruit.
- Potassium (K) boosts disease resistance and overall growth.
Understanding these nutrients helps your plants thrive!
