10 Best Vegetable Garden Fertilizers 2025 in the United States

FoxFarm Big Bloom is a liquid fertilizer designed mainly for flowering and fruiting plants, including vegetables, making it a good fit for gardeners looking to boost blooms and flavors in their vegetable gardens. The N-P-K ratio (0-0.5-0.7) shows very low nitrogen and phosphorus but some potassium, which supports flower and fruit development rather than leafy growth. It is organic, made from natural ingredients like earthworm castings and bat guano, which is ideal for those who prefer eco-friendly options.

This product is slow-release since it relies on natural nutrient sources, providing a gentler, steady feeding compared to quick synthetic fertilizers. Big Bloom also helps strengthen plant roots and enhances flavor and aroma in herbs and vegetables, which can be a nice bonus for home growers. It’s liquid and easy to mix with water, so application is simple and convenient.

Because of its low nitrogen content, it might not be sufficient alone if your vegetable garden needs strong leafy growth or if your soil lacks other essential nutrients. Big Bloom is effective as a bloom booster and flavor enhancer for gardeners focused on flowers, fruits, and herbs, but it may not cover all base nutrient needs for a fully balanced vegetable garden.
