Know before you buy

Yes, this is an all-purpose formula designed for vegetables, fruits, flowers, trees, shrubs, and lawns. Its organic composition makes it safe for edible crops while providing the sustained nutrition needed for healthy grass.
The slow-release nature of this granular fertilizer ensures that nutrients are delivered steadily throughout the growing season rather than all at once. This prevents nutrient leaching and provides your plants with a consistent supply of food for long-lasting growth.
A single 40lb bag of Harmony Ag Organic Fertilizer covers approximately 2,000 square feet. This makes it a practical choice for medium-sized home gardens and residential lawn areas.
The 9% calcium content is added to support robust cell wall structure and overall plant vigor. It is particularly beneficial for preventing common issues like blossom end rot in vegetables and promoting stronger stems in ornamental plants.
You can apply the granules by mixing them directly into the soil during planting or by spreading them topically around the base of established plants. Because the formula is designed to resist wash-through, it stays in the root zone effectively after application.
