Great product easy to spread using the miracle grow spreader tool. Like the fact there is no plastic packaging. Neutral smell & great it’s pet friendly as we have a dog. Looking forward to using more and seeing the grass flourish.
So easy to use

 Miracle-Gro Lawn Builder has become a staple in my lawn care routine delivering impressive results with minimal effort. After applying it in early spring I noticed a significant improvement in the thickness and vibrancy of my grass within a couple of weeks. The slow-release formula feeds the lawn for up to three months reducing the need for frequent applications and mowing. It’s easy to apply especially when used with a spreader ensuring even coverage without burning the grass. I appreciated that it’s safe for children and pets once watered in and dried. Overall  Miracle-Gro Lawn Builder has made lawn maintenance more manageable and has significantly enhanced the health and appearance of my garden.

Wonder product! Got our grass growing amazingly
Reviewed on
This product is amazing. We followed the instructions and also used the spreader to to get an even layer. I am amazed at how well our lawn has come along. It’s 200% thicker greener and feels amazing. The value for money is great and it looks like it’s had ££ spent on it for a fraction of the price. The packaging was so easy to use and the box covered our 200m2 garden with enough to do the same again. We have left it for 3 weeks to fully work with our lawn and I can’t wait to give it a cut and smell that freshly cut grass. This will now be an added step to our lawn care!
Gives off the best in class impression
Reviewed on
Standard packaging for products of this type. Slightly more than other similar items in the market but does give off the 'best in market impression'Seeds were easy to spread using another miracle gro product and settled well on the turf. Now hoping turf will look like the picture on the box in a few weeks time!

Lawn has had a big improvement

This paired with the drop seeder has helped my lawn grow and be very lush and green. It still needs a bit of time and maybe another feed but I am very happy with the results so far.
Great product for lawn maintenance.

The miracle-gro lawn builder comes well packaged in a sturdy box and with instructions how to use it- very handy for someone who hasn't used anything like it before. The 4kg will treat up to 200 m2 lawn. Very good value for money. Promises to feed the lawn for 100 days. Great help for lawn maintenance. Would recommend as does what is says on the packaging.
Excellent effective product.

An excellent durable product that has been so useful in helping me to sort my grass ready for the good weather. Great value and very effective at its job. Good informative packaging with tips and details on its use.
Great value for your lawn
Reviewed on
The miracle grow lawn builder comes in a handy box (fully recyclable) with a handy opening and close lip on the side of the box. You don't need too much of the seed for your lawn when using the Miracle drop seeder along with it. Easy to apply and within about a week and a half the lawn is looking much greener. I will need to use it in 3 months again to help build up to a fuller and lusher lawn. But I would recommend to friends and family.
