10 Best Vegetable Fertilizers 2026 in the United States

Burpee Organic Tomato & Vegetable Granular Plant Food is an excellent choice for those looking to grow their vegetables organically. One of its strengths is the long-lasting nutrient release, which can feed your plants for up to three months. This is particularly helpful as it reduces the need for frequent reapplication.

The granular form is easy to apply, and it releases nutrients immediately, ensuring your plants get the essential nutrients they need right away, while also providing a steady supply over time. The product is OMRI listed, which means it is certified for organic use, appealing to environmentally-conscious gardeners.

With its balanced N-P-K ratio, it’s designed to support plant health and productivity. Burpee's long-standing reputation in the gardening community adds to the trustworthiness of this fertilizer. If you are looking for a dependable, easy-to-use, and organic fertilizer for your vegetable garden, this product is a strong contender.

Miracle-Gro Shake 'N Feed All Purpose Plant Food offers a convenient solution for both in-ground and container plants, providing nourishment for up to three months. One of its notable strengths is the inclusion of vital micronutrients, which can help produce stronger and more vibrant plants.

Additionally, its versatility makes it suitable for a variety of plant types, including flowers, vegetables, and herbs, whether grown indoors or outdoors. This product is easy to apply by evenly distributing the granules onto the soil and working them into the top few inches, followed by regular watering to activate feeding.

Another advantage is that it contains natural ingredients, which can appeal to those looking for more organic gardening options. However, it's worth noting that while this fertilizer is classified as slow-release, which means it gradually feeds plants over time, it may not be as effective for gardeners needing immediate results.

FoxFarm Grow Big Hydro Liquid Fertilizer is designed especially for hydroponic vegetable growing but can also benefit soil gardens. It has an N-P-K ratio of 3-2-6, meaning it is higher in potassium, which supports flowering and fruiting—important for vegetables that produce fruits like tomatoes or peppers. It's organic-based, enriched with earthworm castings and essential micronutrients, helping improve soil quality and plant health naturally. One big advantage is that it's formulated to work well in hydroponic systems by maintaining stable pH and nutrient availability, reducing nutrient lock-up which can limit plant growth.

This fertilizer supports the entire growth cycle, from early leaf development through flowering and fruit production, making it versatile for many vegetable types. Being liquid and quick to absorb, it offers faster nutrient delivery than slow-release fertilizers, but might require more frequent application. It’s easy to use with simple mixing instructions, suitable for beginners or experienced gardeners.

Considering its formulation for hydroponics, it might not be as effective alone in certain soil types without additional soil amendments. Also, the relatively low nitrogen content (the first number) means it may not be the best choice if you need a fertilizer that boosts leafy green vegetables specifically. Additionally, it comes in a smaller 1-pint size, which might not be economical for large garden areas. FoxFarm Grow Big Hydro is a strong option if you want an organic, micronutrient-rich liquid fertilizer that supports fruiting vegetables and hydroponic setups. If you primarily grow leafy greens or need a slow-release option for soil, you might want to look for alternatives.
