Haven't used it yet,been using organic fish out of California can give better reveiw end of season price was good shipping was fast.

Thank you for the 5-star review, John! We’re glad to hear you were happy with the pricing and that your order arrived quickly.

It is great that you're doing a side-by-side comparison with your usual organic fish fertilizer. The Perfect Blend Organic 4-4-4 is unique because of its complex mineral profile and proprietary process that helps build long-term soil structure while providing steady nutrition. We’re very interested to hear how it performs for you and look forward to your end-of-season update!

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!

I have high hopes for this clover in my backyard (which gets absolutely hammered by the sun in the summer)! It has sprouted & I have my finger's X'd that it fills in.

Thank you for the review, Kate! We’re so excited to hear that your microclover has sprouted and is off to a good start.

To help it fill in those areas that get hammered by the sun, make sure to keep it consistently watered through the establishment phase. Once it is fully established, you can then begin to reduce the frequency of watering. We have high hopes for your backyard as well!

Love your product!!! Will be ordering again!!!!

Thank you for the 5-star review, Jay! We’re so glad to hear you’re loving the product.

Applied first application about 2 weeks ago.
Have observed significant less activity regarding ticks being on our dogs.
Have ordered more for a future application.

Thank you for the 5-star review, Daniel! We’re so glad to hear that Tick Killz is making such a noticeable difference for your dogs after just one application.

It’s great that you’ve already secured more for future use consistency is key to keeping those pests away throughout the season. We appreciate your support and are proud to be the company you trust for effective, eco-friendly pest control!
