If you could see within a cluster of daffodils or a lemon tree, you’d discover an intricate mechanism unfurling under the soil. The soil or the potting mix, which appears as a crumbly cake, hides within it lacy fungal threads, moss, microorganisms, and nutrients that together determine how strong the plant will become after it bursts outwards and encounters the harsh, unpredictable world. Gardeners, including Martha Stewart, are swearing by a potting mix from the Miracle-Gro Store, available on Amazon at a 19% discount.

The company says that their mix enables gardeners to make the most out of their piece of Earth by helping even the most stubborn plants grow with ease and grow about twice as big in size. The mix is best-suited for indoor and outdoor container plants, including flowers, veggies, annuals, perennials, shrubs, and ornamentals.

Miracle-Gro’s mix helps replenish nutrients in the soil, prevents soil compaction, and retains water so moisture is available to the plants all the time. Most gardeners who bought this mix share that they’ve witnessed miraculous results. “It has made my garden flourish,” wrote Lwiltsie. Another shopper, Diane Morrow, said, “I love this potting soil! My plants have gone from meh to looking super nice with lots of growth.” One person said that her plants flourished in a way she didn’t expect, “It’s a miracle!”

According to the product description, the bundle comes with two green and yellow packets of the potting mix, each with a 16-quart quantity, and an instruction booklet. One 16-quart bag can fill a 12-inch container, but the amounts may vary depending on the size of the root ball.
