10 Best Organic Fertilizers 2025 in the United States

Miracle-Gro Water Soluble All Purpose Plant Food is a versatile, user-friendly fertilizer suitable for various plants, including indoor and outdoor plants, roses, flowers, houseplants, vegetables, and trees. With a significant 10 lb. container, it is designed to cover approximately 4,000 sq. ft. of garden area. This product claims to grow bigger, more beautiful plants compared to those unfed, thanks to its nutrient-rich formula that starts working instantly.

Jobe’s Organics Granular All Purpose Fertilizer is a versatile option suitable for a wide range of plants, including vegetables, flowers, shrubs, and trees. Its balanced nutrient content with a 4-4-4 NPK ratio ensures that it provides essential nutrients uniformly, which is great for plant health and yields. This fertilizer stands out because it contains no synthetic chemicals and is OMRI listed, meaning it is certified for organic gardening by the USDA, making it an environmentally friendly option.

Miracle-Gro Performance Organics Edibles Plant Nutrition is designed especially for home gardeners growing tomatoes, vegetables, herbs, and fruits. Its nutrient ratio of 9-4-12 (N-P-K) offers a good balance with a bit more potassium, which supports flowering and fruit development, making it well suited for edible plants. Being OMRI listed means it meets organic standards, which is great if you want chemical-free gardening. The fertilizer is a powder that you can apply easily either with a watering can or the specific Miracle-Gro Garden Feeder device, allowing you to cover a decent area (up to 265 square feet). One strong point is that it feeds plants quickly with weekly applications, which can help if you want faster nutrient uptake compared to slow-release organic options. However, because it feeds quickly, it requires regular use to keep plants healthy, which might mean more effort compared to some slower-release organic fertilizers.
