Miracle-Gro and other chemical lawn care products are not bad for your lawn, but they can be harmful to the environment and your health.
If you don’t have to, don’t. When it comes to plants, there are many ways to make sure your garden is thriving. The best approach is to start with the basics: healthy soil, well-placed and properly sized plants, and a water supply that keeps your garden well-watered.
Generally speaking, you should stop using Miracle-Gro and go organic.
