Today, Espoma is the provider of organic fertilizers for the retail lawn and garden industry.

- Reviewed in the United States on January 20, 2023I never really paid much attention to this brand of fertilizer until after I started watching Garden Answer's YouTube videos. I was super impressed by Laura's flowers and results that I had to try this stuff and boy was I glad I did! Last summer, I used this with all flowers, vegetables, trees, and shrubs I planted and was blow away by the results! I have used MiracleGro and Osmocote fertilizers in the past, but wanted to find something organic for use in my gardens so I didn't have to worry about harsh chemicals. I was absolutely blown away at the abundant yields and healthy vigor of my plants this past year after using Bio-Tone. The root promotion and development of my plants was unlike anything I have ever seen with other products.
I will admit, I was a little hesitant initially at trying this product, especially given that it is considerably more expensive than some of the other "big-names" in fertilizers. I was also a little surprised at the "smell" at first as others have commented on. However, after using it I can now see why so many gardeners recommend this product and I don't mind the smell anymore when using it. The results you see are more than worth the money spent! I will only be using Espoma organic products from here on out! Would HIGHLY RECOMMEND!
- Reviewed in the United States on May 27, 2024If you have to transplant anything in your garden, then this product is for you. Last spring we transplanted in the front of our house with 100's of potted plants. Using this product we lost ZERO plants. This starter smells a little like chicken manure but it doesn't burn. It does however work. All our plants are growing well and flowering as we wanted. Couldn't be happier!
- Reviewed in the United States on October 16, 2024I order it every year; it works wonders.
- Reviewed in the United States on July 16, 2024Cant say enough good things about this product. we use it for everything, trees, flowers, and vegetables. It smells horrible, but that's typical for fertilizer.
- Reviewed in the United States on April 3, 2020Laura from Garden Answer introduced me to the product; she doesn't rave about it, she just goes about using it matter of factly. Doing so made me realize she was confident in the product, it would help to produce the plants (size, health) she expected. Thus I picked some Espoma BioStart in little bags. It has provided such great results -- the plants, the seedlings are the proof ... that I now have to buy it in 25# bags. Can't find it in such sizes locally -- they want to sell me dinky 4# bags, of which me and my potting shed laugh uproariously. Used BulbTone when planting last fall -- about 300 bulbs, then used to fertilize those already in the ground. Noticeable difference, the older bulbs performed like they hadn't in years. On the lookout for PlantTone by Espoma, none found locally. I guess i'll order online. Come on Espoma ... help the Meem out; i must garden!
The daughter uses the product too, she can't stand the smell. I think it's just fine, tells me it's all natural. It's a good thing.
Try it, you'll notice a difference.
- Reviewed in the United States on August 2, 2024Love to use this product when planting anything. Helps give plants a great start.
- Reviewed in the United States on July 24, 2022I've used this for years in my garden and found hands down it is one of the best organic plant food products around. Often I will mix this with Espoma Plant-Tone as well in my starter soil for new plants. So if you do the same, be mindful of the directions and cut back on the suggest amount of food per bag since you are using both.
Hope this helps!
Price of the times:
Sadly, as long as prices are crazy for plat food, I've been looking into use more natural products to use. And for those of you who are feeling the financial pinch too, search around the Internet for what folks used before box stores. You'll be amazed at how many free options you have just from waste from the kitchen and a compost pile will do for you. Does take time to cook down but it so worth it.
- Reviewed in the United States on October 22, 2023Dislike Still Waiting For It
But the product is amazing - I have purchased before.
I will not plant without it. Helps establish healthy root system.
