Excellent product!
I have been using Espoma Starter Fertilizer ever since I was introduced by Laura from Garden Answer. It's a game changer...my plants grows so much better. I used it on shrubs, perennial and annuals. I been using it for more than 5 years now.

Works for seeds
I've been using this to start my garden seeds and repotting seedling. It definitely helps with growth. Easy to use and I don't need a lot for it to work so it lasts.

Bloomin
I planted Crape Myrtle’s in the spring using this fertilizer. After I dug the hole, I would sprinkle a layer of the fertilizer on each layer of dirt I added. My trees bloomed and grew since planted. Highly recommended.

Espima Fertilizers
I only buy Espoma fertilizers. I add some in the spring to all my many perennials. All their products are organic which i prefer to use in my gardens.

A must for new plants!
Biotone is an absolute must for me when I am placing new plants in the ground. New plants have the best start with the biotone which contains mycorrhizae. I do not plant without it!!

First attempt at using, and so far, so good!
I had never purchased "starter" plant food before and it was recommended to me for trying to get a Pride of Barbados plant established. So for my 6th attempt I purchased this product and my POB so far is looking like it will last. Will be using from now on for starting plants. I live in central Texas and it has been a challenge the past 4 years after moving from CA.
