Great team and product

Everyone is so helpful there. They keep records of past purchases, which makes purchases easier. Because products are natural, they have distinct odor; it's not a big deal for a quality product.

We are happy that you love the Perfect Blend Organic 4-4-4 Fertilizer! We do our best to make sure our customers are well taken care of! Thanks for the business, we look forward to serving you again soon!

Great with clover blend

Added this to my tilled soil before adding the clover blend, and within three days I had green sprouting!

You made the right choice with Perfect Blend 4-4-4 fertilizer and it sounds like the results are proving that true! Thanks for the business, we look forward to serving you again soon!

Perfect Blend Fertilizer

I have been using this fertilizer for a few years now. What is so nice, first is that the fertilizer is organic. Second once applied per the application recommendations the lawn turns a deep green color but doesn't grow in length like when I used a chemical base fertilizer. It is a win win product and now I do have earth worms in the ground and not killing them with chemicals. Thanks RMBA for helping the earth.

Great to hear of the amazing results with Perfect Blend Organic 4-4-4! It is an amazing organic technology that is great for lawn and garden fertilization! Thanks for the business, we look forward to serving you again soon!

We are looking forward to

We are looking forward to see results with the products grass seed, fertilizers we purchased,but still too early to see any results. The owner and team employees are very knowledgeable and explain all the products and was very interesting. Just waiting for warmer weather to see results.

We are excited for you as well! Just a matter of time and you will have a thriving lawn and well nourished soil! Thanks for the business, we look forward to serving you again soon!
