10 Best Tomato Fertilizers 2026 in the United States

Burpee Organic Tomato & Vegetable Granular Plant Food is a well-regarded choice for gardeners looking for an organic fertilizer. It comes in a 4-pound package and is easy to apply, providing long-lasting results by releasing nutrients over a period of up to 3 months. This makes it convenient for those who prefer not to fertilize frequently. The product is OMRI listed, ensuring it is suitable for organic gardening practices.

The fertilizer supports robust growth and healthy plants by supplying essential nutrients continuously throughout the growing season. It is well-suited for tomatoes and other vegetables, but may not be the best choice for those seeking a synthetic fertilizer with immediate, intense nutrient delivery. Burpee's long-standing reputation and commitment to quality make this a reliable option for organic gardeners aiming for superior yield and plant health.

Burpee Organic Blood Meal Fertilizer is a natural, organic option designed to boost nitrogen levels in soil, which is essential for healthy tomato plant growth. Its high nitrogen content (12-0-0) makes it especially good for leafy vegetables and fruiting plants like tomatoes, helping them develop stronger stems and richer foliage. Since it’s organic and OMRI listed, it fits well for gardeners looking to avoid synthetic chemicals. The fertilizer comes in granule form and is easy to mix into potting soil or garden beds. It also supports soil health by encouraging beneficial microorganisms and can act as a mild pest repellent against animals like deer and rabbits, which is a nice bonus.

It doesn’t provide phosphorus or potassium, which are also important nutrients for tomatoes, so you might need to use it alongside other fertilizers to cover all needs. Application frequency should be moderate, following package instructions, as too much nitrogen can lead to excessive leaf growth at the expense of fruit. If you want an organic fertilizer focused on nitrogen to help your tomatoes grow strong, this product is a solid choice, especially for home gardeners aiming for natural gardening methods.

This 10-10-10 slow-release fertilizer offers a balanced mix of nitrogen, phosphorus, and potassium, which are essential nutrients for healthy tomato plants. Its granular form makes it easy to spread evenly in your garden. The slow-release formula means it feeds your plants for up to 8 weeks, reducing how often you need to apply it—typically twice per season for vegetables like tomatoes.

It also includes a quick-release nitrogen component to give your plants an immediate growth boost, which is handy for jump-starting your tomato plants early on. While this fertilizer is synthetic, it’s versatile enough for a wide range of outdoor plants, including tomatoes, flowers, shrubs, and fruit trees. Just remember to water after application to help the nutrients soak into the soil.

For tomato growers seeking an easy-to-use, balanced fertilizer with steady feeding and occasional quick boosts, this product fits well. Its all-purpose nature suits gardeners who want a simple, reliable fertilizer without fussing over specialized mixes.
