Pro-Gro (5-3-4), organic fertilizer
Pro-Gro 5-3-4 is North Country Organics’ premium general-purpose fertilizer that excels in every application. Pro-Gro 5-3-4 is a high nutrient blend of natural ingredients that plants and trees respond to with rapid and sustained growth, making it the most popular blend of nurserymen, landscapers, fruit and vegetable growers, and farmers.
Its a blend of: Natural Sulfate of Potash, Phosphate Rock, Vegetable Protein Meals, Animal Protein Meals, and Natural Nitrate of Soda.
The N-P-K in the formulation is expressed in numbers. The first number, 5 is "N" for Nitrogen, used by plants for leaf growth and good green color.
The second number 3, is "P" for Phosphorous used by plants to help form roots, buds, flowers, seed and fruit. It's also used by plants to help fight disease.
The third number, 4 is "K" for Potassium, and this helps plants make strong stems and keep growing fast.
We have used it with great results for many years on both our nursery beds and display garden. We find a general application rate of 1-2 cups per established peony or fruit tree to be sufficient for the growing season. Younger plants need less.
Easy to use, no mixing. We favor this product in the farther reaches of the garden where lugging hose or watering cans is not easy. Use it during the spring when there is moisture and scratch it in. If used in summer, water it in or time it's application when there is rain. Product is meant to go down into the root zone, not stay on the surface.
