10 Best Fruit Tree Fertilizers 2026 in the United States

Farmer's Secret Fruit Tree Booster Fertilizer is a liquid fertilizer specifically designed to support the growth and yield of various fruit trees, including peaches, bananas, and apples. With a super concentrated formula, it offers an impressive N-P-K ratio that aids in optimal growth during the early stages of a fruit tree's life cycle, which is crucial for setting the foundation for a fruitful harvest.

One of the standout features of this fertilizer is its ease of use; you only need to dilute a teaspoon into a gallon of water and apply it weekly. This method allows for precise application without overwhelming the tree, which is particularly beneficial for younger trees that require careful nutrition management. The product is also versatile enough for mature trees, allowing for increased dosages as needed.

The emphasis on supporting trees during their early growth cycle makes it an excellent choice for new fruit tree growers. The Farmer's Secret brand claims to bring professional-grade formulations to home gardens, and with its Kentucky roots, it’s a product made in the USA. This may appeal to consumers looking for local products. This fertilizer is well-suited for gardeners focusing on nurturing young fruit trees.

Jobe’s Garden Fertilizer Spikes offer a convenient way to nourish fruit and citrus plants with their slow-release formula. The 9-12-12 NPK ratio ensures a balanced mix of nitrogen, phosphorus, and potassium, which are essential for plant growth and fruit production. These spikes reduce the risk of over-fertilizing, as they release nutrients gradually over time.

Application is simple and needs to be done only twice a year, making it low maintenance for users. The spikes are designed to minimize runoff and mess, which helps in keeping the garden clean and safe. However, being a synthetic fertilizer, it might not appeal to those who prefer organic options.

These fertilizer spikes are a good choice for anyone looking for an easy and effective way to boost their fruit and citrus plant health with minimal effort.

Espoma Organic Citrus-Tone is a solid choice for anyone growing citrus, avocado, or nut trees who prefers an organic fertilizer. It has an N-P-K ratio of 5-2-6, which means it offers a higher amount of potassium and moderate nitrogen, supporting healthy fruit development and tree vigor. The inclusion of 5% calcium helps strengthen cell walls and overall plant health. This product is 100% natural and approved for organic gardening, making it environmentally friendly and safe for sustainable practices.

It comes as easy-to-use granules, requiring no mixing, and should be applied around the tree’s drip line in late winter, spring, and fall for best results. One potential drawback is its medium coverage per 18 lb bag, so larger orchards might need multiple bags or more frequent applications. Espoma Organic Citrus-Tone provides a well-rounded fertilizer option for home gardeners looking to promote vigorous growth and abundant fruit while maintaining organic standards.
