Buying advice

When choosing a garden fertilizer, consider the plant type, soil condition, and whether you prefer organic or synthetic. For quick green-up, water-soluble formulas like Miracle-Gro work well, but require frequent feeding. Organic options like Espoma or Dr. Earth improve soil health over time. Slow-release spikes or granules reduce application frequency. Always follow label rates to avoid over-fertilization.
