Miracle-Gro® Expand 'N Gro® Concentrated Planting Mix
Grabbing the bag of soil on the porch no longer counts as part of your workout when you use Miracle-Gro® Expand 'n Gro Concentrated Planting Mix. The lightweight bag makes it a breeze to move around, but what this mix can actually do will blow you away. Add water, and the compressed coir expands up to 3X, then use it for planting, and expect growth up to 3X compared to garden soil or potting mix.
Why We Love Them
Even after it's done expanding, this mix works overtime. It holds up to 50% more water than basic potting soil and creates up to 90% more air space, giving your plant's roots all the room they need. Plus, it feeds your plants for up to 6 months.
- NPK (0.45-0.15-0.30)
- Covers 4 sq. ft. when used in ground or, after water is added, 2 12-inch containers.
How to Use
Directions for containers:
- Fill the container 1/3 full then gradually add water and stir to make it expand. Total expansion could take up to 10 minutes. Then plant as usual.
Directions for in-ground:
- Spread a 1-inch layer over the area where you intend to plant. Mix with the top 4-6 inches of native soil. Then plant as usual and water plants thoroughly.
Directions for raised beds and other large projects:
- Mix equal parts of the mix and water in a separate container. Once the mix has thoroughly expanded, add it to the bed and plant as usual.
