The ultimate indoor plant and outdoor garden booster, Miracle-Gro Water Soluble All Purpose Plant Food is a simple-to-mix formula that instantly feeds vegetables, trees, shrubs, and herbs with the nutrients your soil needs to grow healthy roots, stems, petals, and leaves. Packed full of growth-helping minerals, this powdered formula quickly dissolves in water so you may feed your plants with a watering can, or with a Miracle-Gro Garden Feeder. When use as directed, this fertilizer will help soil produce noticeably more beautiful blooms, healthier looking leaves, and bigger vegetables, versus those of unfed plants. The formula is safe for all plants in your landscaping beds or indoor planters, from delicate orchids to lush grasses to thirsty ferns. Miracle-Gro guarantees that this product won’t burn when used as directed. For best results, use every 7 to 14 days; just soak the soil at the base of each plant to fertilize the roots.
