Bio-tone is a brand of plant fertilizer produced by Espoma, a company that specializes in organic gardening products. Bio-tone is specifically known for its line of biologically enhanced plant foods. The flagship product is Bio-tone Starter Plus, which is formulated to promote root development, reduce transplant shock, and encourage healthy growth in newly planted trees, shrubs, flowers, and vegetables.

Key features and components of Bio-tone Starter Plus include:

1. Mycorrhizae: Bio-tone contains mycorrhizal fungi, which form a symbiotic relationship with plant roots. These beneficial fungi enhance nutrient uptake and improve the plant's ability to withstand environmental stress.

2. Beneficial Bacteria: The fertilizer includes beneficial bacteria that aid in nutrient cycling and contribute to soil health. These bacteria enhance the breakdown of organic matter, making nutrients more available to plants.

3. Bio-tone Microbes: The proprietary blend of microbes in Bio-tone includes a mix of beneficial fungi and bacteria that work synergistically to support plant growth and improve soil structure.

4. Bio-tone Starter Plus: This specific product is often recommended for use when planting new plants, whether in containers or directly in the ground. It helps establish a strong root system and provides a nutrient-rich environment for young plants.

5. Organic Ingredients: Bio-tone products are formulated with organic ingredients, making them suitable for organic gardening practices. They are often favored by gardeners who prioritize natural and sustainable gardening methods.

6. Slow-Release Formula: Bio-tone Starter Plus is a slow-release fertilizer, meaning it provides a steady and continuous supply of nutrients to plants over an extended period. This slow-release feature helps prevent over-fertilization and minimizes the risk of nutrient runoff.

7. Versatility: While Bio-tone Starter Plus is widely used for transplanting and establishing new plants, Espoma also offers other Bio-tone formulations for various purposes, such as flower tone, tomato tone, and plant tone, each tailored to the specific needs of different plants.

When using Bio-tone or any fertilizer, it's important to follow the manufacturer's recommended application rates and guidelines. Applying the fertilizer as directed ensures that plants receive the appropriate nutrients without the risk of over-fertilization. Always read and follow the product label for specific instructions on how to use Bio-tone or any other Espoma product.
