Great Fertilizer
Always a great fertilizer. Safe and productive in starting plants and helping establish root systems. I use biotone’s products regularly and always have great results.

Love this!
This product is excellent! it worked very well on all of the plants that I used it on! It has repaired the damage that I had on my Rhododendrons. It improved the health on my Boxwoods. It helped my ornamental tall grass grow thicker and taller. This is a high-quality product that i highly recommend. Use as directed as it is concentrated!

I wouldn't garden without it
I use this product in my garden every time I plant something. The plants turn out great and perform beautifully. I think my green thumb has a lot to do with this product. It's organic and I don't worry about using around my food. It does have a odor when you are adding it to the soil, but it goes away and you don't smell it afterwards. I'm used to it by now. I swear by it.

Get healthy plants
I've been using the Espoma Organic Bio-Tone Starter for years. This is my go to for planting new plants and transplants. It helped my plants establish stronger roots quickly, and it's slow release. I also like that it’s organic and contains beneficial microbes and mycorrhizae for better root development. Easy to use, just sprinkle in soil right before planting flowers, vegetables, trees, and shrubs.

Best product for new plants
I use this product in every new plant I put in the ground as well as any transplanting. It works so well that all my plants have healthy starts and don’t suffer from transplant shock.

Great Results!
We added this to our old planters before adding the new annuals. We had beautiful flowers all summer and fall. This was easier and more effective than other brands we've tried.
