Our verdict
Choose by how fast you need results and whether you care about soil. An organic granular like Espoma Garden-tone (3-4-4) releases slowly, builds soil organic matter and rarely burns, making it ideal for in-ground vegetable beds you feed a few times a season. A synthetic water-soluble feed like Miracle-Gro (24-8-16) acts within days and is cheap per feeding, but it does nothing for soil and needs reapplying every 1-2 weeks. For long-term garden health go organic; for quick fixes and container plants the synthetic wins. Many gardeners run both, and either way you should follow the label rates.
