Hi-Yield Grower's Special Fertilizer 12-6-6 (30 lb) is a balanced, slow-release plant food formulated for trees, shrubs, ornamentals and container plants to deliver steady nutrients without harsh spikes.
Whether you tend a landscape, specimen shrubs or potted ornamentals, consistent feeding makes plants healthier and more resilient. This granular 12-6-6 formula supplies nitrogen, phosphate and potash in proportions suited for general maintenance and vigor, with a slow-release nitrogen component that reduces the risk of overfeeding. The 30-pound bag provides ample product for seasonal care of multiple plants across beds and containers.
Applied at the recommended times, the fertilizer supports sustained growth, helping foliage and roots develop through spring and fall. The nutrient mix is balanced to avoid excessive foliage at the expense of root or bloom health. Follow label rates for root-zone application to ensure even distribution and absorption.
Container-grown specimens need smaller, more frequent feedings because potting media flushes nutrients faster. Use the product sparingly on pots and follow the one teaspoon per 6-inch pot guideline to maintain balanced nutrition without salt build-up. Reapply about every six weeks during the active growing season for consistent results.
For landscape trees and shrubs, schedule applications to match their growth cycle—typically early spring before active growth and again in late fall to support recovery and root development. Broadcast or band the granules around the drip line, then water in to move nutrients into the root zone. Consult the label for specific rates according to plant size to optimize results and minimize waste.
Keep the bag sealed and stored in a cool, dry area away from children and pets to preserve effectiveness and prevent accidental exposure. Granular fertilizers are stable when kept dry; avoid freezing or prolonged wet conditions which can cause caking. Use protective gloves when spreading and wash hands after handling.
Who is this product for? Gardeners, landscapers and hobby growers seeking an all-purpose, easy-to-use granular fertilizer will appreciate Hi-Yield Grower's Special 12-6-6. It suits homeowners caring for ornamental beds, professionals maintaining shrubs and trees, and anyone with a mix of containers and landscape plantings who wants a reliable, slow-release nitrogen source. If you need a balanced feed that reduces the risk of burnout and covers a variety of plants, this 30-pound bag delivers practical value and season-long support.
